(Comcast) Connect Modem To Wireless Router/Modem Combo!

Q: (Comcast) Connect Modem To Wireless Router/Modem Combo!

My Motorola SBG901 Modem/Router combo has stopped connecting to the internet. I have done all the troubleshooting with Comcast and with Motorola and it is out of warranty, so I will have to purchase a new one.

In the mean time, I wanted to use it only as a wireless router connected to my Scientific Atlanta DPC2100R2 modem. Is there any way to do this? Is there a way to disable the modem in the SBG901?

Simply connecting with the ethernet cords has not worked. I connected the DPC2100 to the SBG901 via ethernet cord. My computer was able to pick up a wireless connection but there is no cable connection. I am using Windows 7.

Thanks!

Perhaps a really skilled electronics engineer or technician could take it apart, separate the modem from the router portion and add an ethernet WAN port.

Hey Guys. what i need is some help turning my modem/router combo into just a modem so i can use a different wireless router.
My problems with my current combo are that for gaming (pc xbox and ps3 primarily) i have huge connection problems that would all probably be solved with some simple port forwarding. the problem with that, is that my ISP disabled port forwarding and DMZs on the model modem/router thing we have. Networking is not my strong suit so this hasn't gone so well for me in attempts prior to this.

We have an Ambit cable modem/wireless router combo. there is no model number on the modem itself however in the setup page it lists "Cable Modem : DOCSIS 1.0/1.1/2.0 Compliant" which is looking like it may be a model U10C019.

also. inb4 wrong login: user/user. ISP changed admin pass and will not give it to me. i already spoke to them about this garbage.

new router i want to use is a Linksys wireless router. i already know how to do all the major setup on those. its just this ambit one is trash.

thanks for any help you can give me.
 

A:modem/router combo to just modem for use with new wireless router

Not much, if anything, we can do. To configure the modem/router into bridge (modem only) mode you have to login. If you don't have the login/password the only thing to do is reset it to factory default settings.

Two potential problems with doing that ...

a. They may have disabled that function also.

b. You have to know the settings needed to connect. (Usually not a problem with cable service.)

DSL modem/wireless router combo for AT&T?
Is this a crazy idea? will it work?
I just killed my DSL 2wire modem wired connection by trying to add a wireless router. Attempting to bridge, I changed a setting and now I cannot even reach the modem with the computer.

so, since I am in the middle of hassle anyway, I am considering just replacing this old (6-year-old) modem, and replacing with combo DSL modem and wireless router.

Has anyone done this? suggest a model?

I'm switching from AT&T U-verse to Comcast since comcast can offer speeds up to 5x faster.

As you might know At&T uses ethernet as incoming signal vs. Comcast that uses 75 ohm cable.

I need to buy a new modem and router to install the new Comcast service.

I have two questions:

1) What is better? the combo modem/router units (i.e. Motorola SBG6580) or buying a separate stand-alone modem Motorola 6141 modem + Netgear N750 wireless router)?

2) I do have one issue to overcome. I have one TV in my house that is wired for cable only. That is, it has a cable run going to it. It's too difficult for me to install an ethernet run to it, so I'm stuck having to use the cable run. Are there modem/routers that have a cable OUT so that i can feed this TV its hard-wired signal?

Thanks,

The two dns servers you show, 75.75.75.75 and 75.75.75.76 belong to Comcast so that must be your ISP.

Try opening an elevated Command Prompt and entering ipconfig /flushdns, see if that helps.

I have an office over my garage (detached from my house but only about 30-50 feet from modem in house).
The wireless signal is very weak. When I had the modem in the garage office, the wireless signal to the house was weak. Comcast thought their new wireless modem would address this, but it has not.

So, I have run a cat5 cable from the modem across the yard to the garage and hardwired it into a Linksis WRT54G Wireless Router.

Although I can connect to the router wirelessly, I cannot get internet access on my computer. I called Comcast, and they said they would have to disable the wireless signal from the modem if I want to activate the wireless router. I do not see how this will solve anything. They mentioned that to have 2 active wireless signals would create interference. Is this true? I can hardwire my computer to the router, but I also use a laptop and other wireless devices that I would really like to have a strong signal for.

Please advise.
 

A:Is it possible to run wireless router off of wireless Comcast modem?

It should be possible without to much fuss.

I'd guess that you may have double WAN'd your network. The Comcast wireless device is determining what IP addresses all of your devices are supposed to get, and your WRT54G is probably doing the same thing. Both devices are probably set up to automatically provide DHCP services, and they are clashing with each other. The range of IP addresses for both devices may not even be the same. Since your WRT54G is an aftermarket device I'd disable DHCP on that machine (because it'll probably be easier to do and your Comcast device is closest in line to the modem because it is the modem, Oh and you'll have to log into your WRT54G's admin page to disable DHCP ) and make sure the line that runs from the Comcast device to the garage isn't plugged into the WAN port on your WRT54G router but is instead plugged into one of the four network/internet ports. The WAN port is the single port off to the left of the other four ports when viewed from the back.

It's possible with the right equipment to bridge two wireless routers and extend the range of your home network. A Linksis WRT54G firmware can be reflashed as a DD-WRT machine and bridged with another DD-WRT router. I know it's possible because I've done exactly that at my house.

You'll want to got to http://www.dd-wrt.com/site/index for any additional info on how to do that.

Info about my computer (should it be relevant) is below.

Short Story: I desired a new router/modem just to see if it would improve internet consistency. However, I ended up buying just a router. I have a modem and can link them up. Should I keep this setup, or switch back to my old Router/Modem combo, while looking for another Router/Modem?

Long Story:
My internet, for the most part, is fine. However, I still experience the occasional disconnect. My internet will go off for less than a minute about 5x a week. This is fine for browsing, but sucks for gaming. My ISP is AT&T, and I have 3 Mb max DSL. Years ago, it started having a bunch of disconnects after I tried an upgrade (6 Mb max) for a year. The techs came out about 6 times. As a result, I downgraded my service back and got an AT&T 2Wire Router/Modem combo out of the deal. I know people say this device sucks a lot, but it's been at least doing its job. General browsing is fine, gaming has the disconnect problem only sometimes, and there's only one device to think about.

However, I've recently started wondering if the quality of the modem was in fact affecting the consistency of the connection. The techs tried different modems when troubleshooting everything, but none were high quality.

So, I got my eye on this:

A:Separate router and modem vs Router/Modem combo...

i would not see any advantage

but why not try it for a week and see if it disconnects - that is what you are trying to fix

also you wont get a faster speed if the download is set to 3Mbps and all wireless modes B,G,N will be faster than 3Mbps anyway

How many devices do you have connected to the router and when you get the disconnect is it for all of them

it maybe a dns issue - but you would need to see if the new modem/router setup has resolved the issue anyway

Can't the DSL is the input and ALL connections to the device will (internally) use the router portion. The bandwidth you see is NOT restricted by the internal router however - - it's the DSL itself.

Hi everyone, this is my first post here. I've trawled the net for ages but have found nothing. I believe I have a unique situation here and would love some help from some net savvy people. I have strong computing skills, but keep away from networks if possible. Hope someone here can help, would really appreciate it.

Here's my current setup:
- HP Pavillion Laptop with Windows 7

It all works well, internet is fine, I'm happy.

Why I want to share this network connection:
I have a couple of iphones and a Nintendo Wii and we would like to connect them to the the laptops internet connection.

You enable Internet Connection Sharing on the internet connection and configure the Belkin as follows.

JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers... Read more

Its been a long time since I've posted but you've never let me down in the past.

My father in law connects to the internet by a dialup modem on his XP desktop. This is shared by a crossedover network cable with an XP laptop.

Now for his birthday I wanted to make the laptop wireless, I couldn't get hold of a wireless access point so I got him a wireless router (netgear wgt624) instead and a PC wireless card for the laptop.

Now I'm not sure how to connect things up.....

I have read that "to use the wireless router as an access point you need to connect via the LAN ports to the router and disable DHCP and reset the IP address of the router. Then with the desktop connected to the LAN port (rather than the WAN port which should be left unconnected) you configure the router and simply plug the card in the laptop and away you go". This description was from sites suggesting that there would be an existing router on the network which should continue to be used as a dhcp server and that no network should have two dhcp server.

My query is that since there is at present no other router or DHCP server on the network(though I don't know how the laptop gets an IP address) could I simply plug a standard ethernet cable from the desktop into the WAN port of the wireless router?

You can share the dial-up connection using Windows in-build ICS (internet Connection Sharing) software. ICS is a DHCP server. Your wireless router connected up as an access point as you described will work with that. Type ICS into the XP Help pages for guidance.

The modem needs to plug into the WAN port on the router first.

If the router has 4 ports just plug the 2 machines into the LAN ports on the router.

You can also add a switch with more LAN ports which you would plug into the routers LAN port using Ethernet cable.

I have a Motorola Modem (SB5120) from Comcast, I have connected to a Belkin router (F5D5230-4)

The Problem I am having is that when I hook the Modem alone I have super speed downloads and I stay connected all the time.

When I am hooked to the modem and then to the router, my speed is cut almost in half and on some sites I get disconnected??

One site told me to ck my TCP config to see if I can increase my TCP connections.
It was set at auto sense, I called Belkin and they said that I should change the setting to 10baseT, and to download the new Firmware from there site.

I did all of the above, still slow, but a bit faster. Still get disconnected but it finds it self and reconnects most of the time?

What I would like to do is connect the main computer direct to the modem and then the other 2 computers thur the router.
But I am not sure if I can, or not and how??

The Modem has a USB port or a Wier connector, but you can only use one??
Is there a splitter of some kind that I can get??


Sorry for such a long first post!! But i am trying to give you all the info I can.

O yea I run a Dell 4400 Pentium 4, 1.6 MHz, 512 ram, 165 gig HD, CDrom, CD burner and Floppy

Thanks!!!!

So Comcast wants me to use their high speed router/modem but the Linksys router I have (plus their modem) has been working quite well for many years.

They promise my speeds will be higher. Right now I'm at 54 Mbps. No problem here, if it ain't broke...

Should I just install it?

I just moved to a new home. In the previous home, my XBOX was connected by wire to a Linksys wireless router, which was connected to a Linksys modem, which was connected to Cox Cable.

My new home has Comcast. The modem is a new Motorola SB6121, and the router is a new Medialink N router. I cannot get the 360 (or my Roku box or my DirecTV CCK) to connect to the Internet no matter what I do. I do not have a wireless adapter on my XBOX 360, so I've been trying this all through a wired connection.

First, I should note that I have had no trouble getting my laptop to work through either a wired or a wireless conection.

I first tried something traditional: modem->router->360. When I go into Configure Network, the XBOX has all the correct IP/Subnet/etc. (verified by the numbers on my laptop). When I run a test, it gets past the Network test, but it cannot connect to the Internet.

I have also tried MAC cloning, port forwarding, DMZ, disabling the firewall, IP/MAC binding, and reassigning my XBOX the same MAC address as my laptop.

I have even tried connecting the XBOX directly into the modem, bypassing the router completely. Again, it is assigned proper IP/DNS/etc., but it can't get to the Internet.

Nothing I have done has connected by 360 to the Internet. I also called Comcast and they could not help. I'm really at the end of my knowledge here. I've tried every setting I can find.

Every time when we come back from work (i.e., connected to wireless networks at work), we need to restart the modem and router before our laptops can connect to our home wireless network. The error message is "This connection has limited or no connectivity. You might not be able to access the Internet or some network resources. "

We never had this problem until I changed from WEP to WPA2. The current settings are:

on the router (D-Link, DI-524): WPA2, PSK
on the laptops: WPA2-PSK, AES

It doesn't look like that our laptops do not support WPA2, since they would work after restarting modem and router. And it works fine as long as we are at home, whether we restart our laptops or not.

I am totally confused and would appreciate any thoughts you can provide! Thanks!

A total non-tech guy here. Have old Dell desktop connected to Comcast modem (ARRIS TM502G). When Comcast set it up they used USB connection rather than ethernet. Recently bought new Dell desktop and Netgear wireless router. Tried setting new computer/router up to modem. Router is looking for a static IP address, but Comcast says I am set up for dynamic. Finally gave up on setting up router and have just been trying to get new computer to connect. Feel like if I can get computer to connect I can get the router set up. So I don't even mention router to Comcast anymore. After telling me mulitple times how to power cycle everything, and me doing so 57,000 times , they blamed Windows 7 and told me to call Microsoft. Instead I hired a tech guy to come help. He had no luck at my house so took the new machine home with him, and instantly connected to internet with his Comcast modem. So he brings it back and says it's on Comcast's end. Getting nowhere with Comcast. I explained (mulitple times) that it's connecting on the tech guys modem but they continue to say the computer is not set up correctly but have yet to help me out. I asked for a Comcast tech to come take care of it but they say they will but if it's not a Comcast issue I will have to pay for tech visit. I wouldn't know enough to know if it was a Comcast issue or not so would have to take his word - so not excited about this prospect. Again, have power cycled everything every different way possi...

Hey All,

I have a Wireless Modem that works perfectly (i can use the wireless fine) but i need to connect it to a Wireless Router. But it won't work.

I also have a non-wireless Modem that when connected to the wireless router everything works great. But i have to return the non-wireless modem.

I think it might have to do w/some gateway settings on my wireless modem. Any help is appreciated.

thanks,

A:Can't connect Wireless Modem to Wireless Router

"won't work" means what? Both devices refuse to power on?

What modems are these anyway? Dialup, cable, DSL, some special wireless connection?

Gateway settings on the wireless modem? If that modem cares about gateways and such, then it is a router device and you should connect it to one of the LAN ports of your wireless router. Disable the router's DHCP server and make sure you don't have any IP address conflicts.

I am in the process of dumping AT&T DSL in favor of Comcast Broadband. (Considering their "performance" package at 25mbps) to replace my current overpriced 1.5 mbps DSL. (It was the only thing I could get in my subdivision about 12 years ago).

I have been running a Netgear N300 ADSL2+ Modem/Router and two Linksys WRT54G2's configured as wireless access points in my 3 level home for the last 3 or 4 years with virtually no problems.

I am no where close to expert, but not a novice either. I was able to set up the above with a little help and advice from this forum.

I would appreciate any advice regarding hardware, etc. I am looking at a Motorola SBG6580 as it is about the only combo modem router on their "approved" list.

I am not heavy into gaming etc. but, I would like to be able to download maps to my garmin gps in less than 4 hours and download the occasional movie in less than the current 8 hours. I would hope to also get better response from two iPads, and two smart phones that run on my network.

By the way, also going to dump AT&T voice in favor of an Ooma Telo if that makes any difference. Looking at prices, I can pay for voice and HSI for less $$ than I currently pay to AT&T.

I have a Belkin F5D8235-4 router and for the life of me it does not operate normally with my comcast RCA cable modem.

I've read on the net the others are having the same issues. Main issue is that the router only works in simple default mode (dynamic IP) and the moment you start tweaking the settings for private IPs ect...it disconnects and then you have to restart and rest.

Anyhow, I'm in need of a new recommendation for a router that works well with comcast cable modems.

Anyone have a suggestion?

Okay so to save money my mom went on the Comcast triple play deal, and today it was installed. We got the big, black Arris modem, model TM602G, and it's plugged in via a telephone wire to our main phone base, coaxial cable line from wall to modem, and the ethernet line that's plugged into my laptop.

Now we were on Verizon before, and our router, the Netgear wgt624 worked perfectly fine on it. Now, with Comcast, I can't get any wireless. As soon as I plug it the ethernet to the back of the router, I get nothing. I've changed the router settings and deleted the old account information, even tried putting in the new account info. Tried using the setup wizard and it says we need a static IP. So, I call Comcast and they tell me they use dynamic IP settings, of which I was already doing. So, they reset my Arris modem, and then when everything's set they call me back, and we continue to diagnose. Then they give me the BS of that since my router's not a Comcast-owned router, they can't troubleshoot it and I'll have to call Netgear's tech support.

Now I am fairly smart with this networking stuff and I am not calling Netgear unless I have to...my voice is shot to hell no thanks to Spring allergies and I have a feeling just one setting needs tweaking....but what?

So, any suggestion?

Hey guys. I was wondering if there was some buying advice you could give me on a modem.

I have ADSL service with ATT, and upgraded to a 6 Mbps package at the tail end of last year. However, I've had DSL since the early 2000s, and the modem (Speedstream 5360) is so old it can't really keep up. The DSL connectivity will sometimes blink off and then back on, and it really flares up when I play online video games. I get dropped from games left and right. I've already had an ATT technician down here to see if it's the wiring in the phone jack or the modem. He said it was the modem, which I believed. He suggested an ATT 2Wire combo modem/router. I didn't buy it, as it got slammed on amazon. But that got me thinking, since I need to replace my router (Airnet AERO14) too. Maybe I should kill two birds with one stone:

1.) Should I get a combo Router/Modem? What are the pros/cons?

2.) If a combo does work, do you guys have any recommendations? I was looking at this one:
http://www.amazon.com/D-Link-DSL-2540B-4-Port-Ethernet-Router/dp/B000O0XW7E/ref=cm_cr_pr_product_top
But I'm all for anything that's cheaper, and people have been talking on that router's review pages like it has a problem with ATT (my provider).

If you guys need any more pertinent information that will help me, let me know. The maximum budget I'm working with here is 70 bucks.
I'm on Windows XP w/Service Pack 3.

I'm having problems getting my home network to work smoothly. I believe it is in the communication between router and cable modem. I think these problems all started when Comcast implemented Bridging in the modem(im not positive). Not sure if this is IP address related , MAC address related or another problem. What I do know is that.....

A. Sometimes even the wired connection to router goes out and can require some or all of following. Restart Modem, Restart Router. Restart Computer and/or "repairing" network connection.
B. Wireless connection..Wireless Networks can be "seen", but cannot get an IP Address when "repairing" or connecting.
Any type of Description to how routers/computer/modem interact would also be appreciated.
 

A:Comcast+Motorola Cable Modem+ Any Router=Problems

A. Sometimes even the wired connection to router goes out and can require some or all of following. Restart Modem, Restart Router. Restart Computer and/or "repairing" network connection.
B. Wireless connection..Wireless Networks can be "seen", but cannot get an IP Address when "repairing" or connecting.Click to expand...

B is a consequence of A, so make A work reliably first and then address the
stability of the wireless thereafter.

Lots of issue here, including specific brand names and even model numbers.
At the top of your list of suspects is Comcast; there's a lot of flap re their support.

An ISP can configure their end to be very parochial to force specific
operations, such as allowing access to only KNOWN users. When installed,
they can record (assuming no router is yet installed) the MAC of the system
that is connected. {hint: this is a good security measure for even your LAN}
This is also where your WAN (ie public) IP-Address gets determined, either
statically per your service contract or dynamically via DHCP on the ISP site.

If your ONLY system is directly connected to the modem, it will receive these settings.

Modems are transducer devices, ie they change one technology into another,
just like a radio changes a/c or d/c power into rf and then into audio.
Most of them have little functionality beyond that.

Routers are great devices and have many features. The most important is

Hi,
Moved into a home that has a wiring closet in the basement. Typical wiring closet setup, Cat 5 cables and Coax cables from the house outlets terminate there. There is a Suttle sam v8m voice distribution module installed. Looks exactly like the one in this user manual:

Page 5 of 8, Wiring Diagram.
http://www.manualslib.com/manual/68953/Hometech-8-Port-Voice-Module-Sam-V8m.html?page=5#manual

However, there is NO Sam D8 switch below installed in the wiring closet. The Cat 5 cables from the home outlets enter the wiring closet and plug directly into the Sam V8m.

A couple questions.
Can a comcast modem be connected to the Shuttle Sam V8m to make the Cat 5 outlets hot? Or, does the Sam D8 (or similar) need to be installed?

How should the Comcast Modem be connected to the Suttle Sam V8m? In the User Manual diagram above, should a Cat 5 cable run out of the Comcast Modem and connect to the Line In on the Module (labeled as 1-4 Lines In). And, should this be a "straight through" cable - Brown/BrownWhite/Green/GreenWhite/Orange/OrangeWhite/Blue/BlueWhite? This is the color scheme top to bottom on the Sam v8m. This image is similar, except it does not have a Test port below the Out and Security Port. you can view the color scheme on the Line In

Hello,
I'm not much of a tech savvy guy so bare with me here, I'm currently having an issue with my router. I have a belkin n450 DB wireless router (model f9k1105v1) that has been having issues resulting in a "no internet connection". after some research on this topic, I didn't find much except that my modem (which is an Comcast arris modem) might not be able to connect to the routers settings. I have tried everything from resetting my Belkin router and unplugging everything, and still no result! - may I add this router is a solid orange colour when. it should be a solid blue - I am aware that resetting the router sets it back to factory default settings. So I guess my initial question being, since I have little experience with this situation, what steps can I take that are a bit easy for a person like me to comprehend? Thank you for your time and knowledge in advance! NOTE- I've had this issue before in the past and I solved the situation from some tweaking with the cords and it worked just fine, except I had to use the default password for the router. Although now tweaking with the cords isn't a solution.
