Cable modem to DLink Router can't find IP address

Q: Cable modem to DLink Router can't find IP address

Hi all -
we were happily getting along with our RCN cable Motorola modem and DLink wireless 655 until the last couple of weeks. The internet would intermittently not be available, without warning. First couple of times we power cycled the modem and router, and it worked, but then stopped being available altogether. I got some support from RCN, the cable provider (they own the modem and it's old, so naturally that was my first thought). I now have a new modem and the situation is exactly the same.
The error message that I get is that the IP address for the network cannot be found.

I got internet access by bypassing the router, connecting the modem directly to my (Windows XP) PC, releasing and renewing the IP address, and power cycling the modem. However, the internet still intermittently shuts down, and of course turning off the computer necessitates the whole procedure again. And now we have no wireless.

SOooo - should we assume it's the router, and a new one would solve our problem? Of do we just need to reset the IP address of the router? Or has anyone heard of this and maybe has some light to shed...???
Many thanks

Preferred Solution: Cable modem to DLink Router can't find IP address

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I got internet access by bypassing the router, connecting the modem directly to my (Windows XP) PC, releasing and renewing the IP address, and power cycling the modem.Click to expand...

Power cycling the modem is necessary when switching the device connected to it; after that there should be no need to power cycle it until the next switch.

However, the internet still intermittently shuts down,Click to expand...

Implies ISP, modem, cable or computer problem. If you have another Motorola modem you have LEDs that give a pretty good idea of what might be happening. And most modems have some LEDs. What are they telling you on the "shut downs"?

and of course turning off the computer necessitates the whole procedure again.Click to expand...

Shouldn't have to do anything but power up the computer. Can you try another computer? If the modem has a USB port can you try a USB connection?

A:Ip conflict with cable modem and dlink router

Read other 8 answers

I have a motorola SB5120 surfboard modem, an adelphia cable internet connection, and a DLINK - DI-514 wireless router. When I connect my modem directly to my computer, the internet connection works fine. When I connect to my router, it will work for like 5 minutes and then just lose the connection "can't find server". A few weeks ago, everything was fine, but since I just got this new modem, I don't know if its the modem or if it's the router -- if I need to replace either.

I have tried the renew and release, I've tried resetting the modem, uploading the new firmware. DLiNK tells me something on my computer is blocking the signal -- a firewall because there are always all the lights on my modem when I'm connected directly and when I'm connected through the router.

i must also mention that there are times when i'm connected directly to the computer and not the router, i also lose the connection -- even with all the lights on -- that I have to do a renew/release.

I hope that you can help me figure this out.

A:DLINK losing connection/cable modem

Curious to know if you reset the D-Ling back to factory setting and start from scratch with the setup? If you didn't you may have some setting in there preventing the router from obtaining the info from the modem.

Try resetting the router, then turn everything off. Start by turning the modem on, let it stabilize, then the router...give it a couple of minutes and then the computer.

I've had a dlink604router connected to a dsl modem for the longest time with all my computers receiving internet without any problems. I just switched to a cable modem and the router blinks as if it's communicating with the modem but no internet is getting to the computers connected to the router. I've always left the dlink's settings to default-my 2 macs receive automatic dhcp. Does anyone know if the settings on the dlink have to be changed to communicate with the new cable modem? and if so,the steps that would be needed to make that happen? Any info would be greatly appreciated. Thanks!

I am trying to connect my DSL modem to a DLINK router with no success. I am able to get into the DSL modem but not the router. I have tried 2 different routers and get the same results. My computer shows it is connected but it is not.

The DSL modem is an ActionTech M1000 and supposedly is a modem/router. It works fine directly connected to the computer.

The routers are DIR-615 and a DI-604. I have used the DI-604 in the past with no problems.

For both of them, I connected from the modem to port 1 on the router. Then from the router's WAN to the computer.

I turned off DHCP in the modem and got the same results. It is PPPOE and according to them it is dynamic, not static.

I powered everything off and on and still no connection.

Any help would be appreciated.

I've got a D-Link DSL-G604T wireless router. My internet connection is Optus Satellite (Australia) with a Gilat SkyEdge modem. I'm using a Toshiba laptop running windows Vista.

Here's my problem. I can get connected to the satellite internet when I connect directly to the modem using a crossover ethernet cable.

I can't seem to get the wireless router connection to work, though.

I connected the crossover cable to the Dlink router and then used a regular ethernet cable to connect to my laptop and set up the wireless connection.

I AM able to get the wireless single excellent strength from my laptop to the router. The problem is the router and modem don't seem to be communicating properly.

In my network and sharing center it shows a good connection between my pc and the network but a red X between the network and internet.

I did have this all set up and working properly about 10 months ago, but I was traveling overseas and now can't seem to get it working again since I've returned.

Unfortunately the satellite internet provider (Optus) will not offer any tech assistance for the wireless side of things. They'll only ensure you've got a direct connection.

I'd appreciate it if one of you tech folks could help me figure out my failure to connect issue.

Thanks in advance,

Hello Tech Guy forums. I came her insearch for some help. I am running Windows XP Professional. Now, the problem that I have. I am running highspeed and, when I connect directly from my DSL modem to my computer, it is pretty fast, but, when I connect my DSL to my Router through than WAN port, than connect my computer to one of the LAN slots in my Router, it runs terribly slow. For example, I am downloading 3 movies and, when I was directly connect from DSL to computer, the time to download all three movies would take 3 - 4 hours. Now that I am connected to my Router, it will take a week!!

Now, I am also wanting to use Router so I can share my Internet with my Xbox for Xbox Live and my other computer. If someone could help me out, I would greatly appreciate it.

Thank you.


A:Internet Running Slow - DSL Modem through WAN on Dlink-604 Router

I saved the following some time ago. It may be pertinent to your problem.

On your router there should be an option for mtu. use this formula.

To find the proper MTU Size, you'll have to do a special ping of the
destination you're trying to go to. A destination could be another
computer, or a URL.
1. Click on the Start button, then select the Run option.

2. In the "Open" field type in command (If you're using Windows
2K/NT/XP use CMD instead)

3. Once the window opens, you'll need to do a special ping. It
should be formatted:

ping [-f] [-l] [MTU value] [Enter] an e...rom this into the MTU settings on the router.

Hey everyone.

I've ran into a problem that I can't quite figure out. My internet connection shows 'no internet access' even though my ISP shows the connection is coming into the house just fine. I usually use a router (NetGear-WNR3500U) but I right now I have the Ethernet connection plugged directly into my PC. I tried directly plugging into my laptop and the internet works just fine. So I know the problem resides in the PC.

Some troubleshooting things I have tried.
-Power cycled my modem, router and PC.
-Repinged my connection from my ISP(Comcast Xfinity)
-Used the reset option on the router and the modem
-I was walked through the internet options needed with the tech support from my ISP to make sure DHCP was enabled and every other setting was correct, and he cleared me that all settings were correct.
-Tried ipconfig commands to /renew and /release my IP
When I tried ipconfig /renew I get the error 'An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server'

-Restored my PC to a restore point where the Internet was working

All of these options did not work.

What I think the problem is and I am not sure how to fix it, when I run the ipconfig /all command my Auto configuration IPv4 Address shows which I was told is a router IP address even though I am plugged directly from the modem to my PC with an Ethernet cord. So I think that's my problem? But I am not sure.

I recently bought dlink D2750U WIFI ADSL modem/router, for my ADSL internet connection.

But I have now changed my ISP, who provide internet via cable(not telephone line). The ISP guy provides a cable modem(old modem) along with it.

I have connected my PC this way:
Cable modem -> Router -> PC through RJ45. I am able to access internet from my PC, but I am not able to get wifi working on the router. And I am logging onto internet through a dial up connection.
1) Please help in configuring the router to get wifi working.
2) Also, my default gateway seems to be either or blank. So, I am not able to login to the modem unless I remove the modem connection. Please let me know if I am doing anything wrong here.

A:Using dlink D2750U Wifi Modem/Router As a Wifi Router

Hey Narain. The D-Link unit you have appears to be a combo unit (modem and wireless router) since it connects straight to the RJ-11 phone line. This unit won't work with an ISP that provides service by way of coax cable. The D-Link will work if you want to use DSL, but you need a cable service compatible modem or combo modem/router if you use cable service.

Charter up my internet price and told me they would put me on a promo plan if I came in and got one of their modems. I picked up the modem (Cisco DCP3008) yesterday and hooked it up tonight. I had everything connected through my DIR 615 and Charter came up asking me if I was upgrading, etc... needing to verify and so on. I went through that and the last step it said it need to restart the modem to finalize. The modem restarted and came online, however the browser never indicated the processed had finalize. I call Charter, we wired the modem directly to my laptop and got a connection. I thought things were good. I hooked back into the router restarted the modem, all lights came on, started the router and no IP address. I went into setup and clicked clone MAC address and hit save, still no IP address after going to status, dhcp release and dhcp renew.

I reset the router back to factory settings and it still would not pull and IP address. The router worked great before the new modem. Any suggestions to get my router to pull an IP address?

Hi, I have a strange question that im hoping can work (for a fortnight at the most lol)

I have just joined Virgin Media on 20meg connection. They sent me out an Ambit E08C013.00 modem but forgot to send out the router. Then the engineer installs the wallbracket lobsided! But anyway, im getting away from my question.

I have to wait up to 2 weeks for my router and in the meantime, my computer is upstairs and my connection is downstairs! I dont want to buy a router that will last me 2 weeks, so I decided to dig out my old BT Voyager 2091 router. I connected it to my Netgear FS208 v2 ethernet network switch and now I am trying to get it to broadcast my BB signal from my Ambit modem (which is also connected to my Netgear switch)

I can now connect to my wireless router, but it will not broadcast my broadband.

Is there a way to fix this? Or do I have to wait till my new router arrives?

Okay, so this is basically my setup.

I'm using roadrunner's sb5101 cable modem...connecting this modem to a netgear hub with 4 ports.....

1 port receives the connection from the cable modem
1 port connects to my computer
1 port connects to my 360
1 port connects to my dlink router

here's my problem: all the connections work fine except for the dlink router; it doesn't seem to connect to the internet.

When I check the status tab, it says "dhcp client disconnected". I try the release IP and it says it was successful, but nothing happens. I try the renew ip and it says renew ip fail (obviously since it doens't have an ip).

So my question is, is it a crappy router? Am I missing something here?

I tried resetting the router to factory defaults by pressing the hard reset button in the back, and it sitll didn't connect.

Someone please help.

Oh, the reason i'm not connecting the modem to the router is beacuse the stupid router doesn't give me a static ip, so i'm banned from several sites and I need a static ip.

Alright...so I will start off by stating that I hate my apartment and how the cable is wired in the place. I have one line going into the apartment. It is in the living room. In order to get too any other point in the house I have too run cable lines around rooms and hook up too connections in wall that pass through the wall into the next room. I currently have my computer located in the dining room/kitchen area as I have a huge area and a small table. Too get too my computer with cable line it takes 3 connections to hook up too my modem (modem is last hook up). I would like to move computer too too bedroom, but too do so would take 6 different connections. Would I be losing "connectivity/bandwidth" by having 6 different connections or would it be better to get and hook a router up in living room and run a network line too the computer and cutting out those connections??? I would like to get the most out of my internet connection if you feel me.

Basic question? Will I get better connection using router over 6 connections??? Not sure about data/packet lose in the connections.

According to the user's manual on my cable modem (a motorola SBV5220), "You can connect a single computer to the USB port and from one to 31 remaining users to an Ethernet hub, as shown."
Here's the diagram (as well as i can get it - cant find the manual on-line):

Comp \
Comp---Ethernet Hub or Switch----Cable Modem
Comp /
Does this mean that I could use an ethernet hub or switch to share my connection over 3 or 4 computers, or would i need mutiple IP addresses to be able to do this (in which case i would use a router instead)? Tech support at motorola referred me to Time Warner, and TW's tech support had no clue what i was talking about.

Just seeing if i can save a couple bucks. If anyone understands what i'm trying to say, thankyou for your assistance.

A:Will my cable modem serve as a router?

That tech support person at Motorola certainly is not on the "A" team.

I found the "data sheet" online. No mention of the magic words "router" or "gateway" so I think that it is safe to say the suggested network (which is also in my Motorola SB4200 manual) implies multiple IP addresses.

As you suspected, you want to put a router in that diagram in place of "Ethernet Hub or Switch."

I have a crossover cable, but not sure why I would need it if I'm connected to the router. I have zero knowledge of setting up networks.

A:Cable modem to Lynksys Router to 2 pcs - how?

If both computers are successfully connecting to the Internet through the router, you do not need the crossover cable.

Make sure you can ping the other computer's IP address. If this fails, just for testing, make sure you turn off XP's as well as any other firewall.

Make sure you can ping the other computers by name.

Make sure you have the same workgroup name (watch for trailing spaces)

For troubleshooting purposes, turn off XP's and completely uninstall any other firewall software. You can always add more complexity after you get it working.

With XP, make sure you have the same username and password as the person logging onto the other computers. The default setting for XP Pro is to require a password for network access.

More details about how to network XP can be found at:

There continues to be a lot of misinformation about needing NetBEUI or to changing the NetBIOS setting. You can ignore both. Installing NetBEUI to solve a networking problem will just mask a some underlying and potentially important misconfiguration with TCP/IP. The default NetBIOS setting works fine so there is no need to change that either. Just don't disable it.

I have my router (Netgear RT314) and my cable modem (RCA DCM 215) hooked up and am having problems. I can connect for 30-60 min, but it will then dissconnect and I have to reboot the router in order for it to reestablish the connection.

Is there anything I can do to rule my router out as the problem?

Im about to purchase a router for my house's new cable i-net connection. They charge 14.95 per extra isp, so i thought this would be the best way to do it. I got 2 questions. Now when the DHCP server onboard the router assigns ip address, are these unique to the network. I mean, when i video conference with my family on Netmeeting, and i give them the ip addy that shows up on my "ipconfig" utility, will it ring on all the other computers attached, or will it only ring on my computer. I know routers are usally good at splitting signals...but how good? Also, alot of routers claim to be say 4-port, but isnt one of these ports already taken up by the cable from the modem to the router, so in essence 3 avail. ports. Or would i be able to purchase a cross over cable. Plug one end in the modem and plug the other end in the "wan" or that seperate slot in the router, and have the 4 computer slots in the router for 4 computers? Whats the best way. Speed is sort of an issue, but im runing on a 14.4 cell connection right now, so anything will be better. Please let me know the best way to use a router. I have 5 computers i think that want to connect, but the only other routers i see after 4 port are 8 port. Please Help

I am using Motorola SBV 5121 cable modem + Dlink 615 wireless router. I often encounter waiting long time to get web page, sometimes so long that I just restart the modem and router. What is the problem and how to resolve?

My ISP technical support always tell me to unplug the router and test with the modem directly, if no problem then is my router problem. Is it really my router problem?

I use speedtest.net to test, it show download speed about 12 to 17 Mbps, upload speed about 1.1 Mbps, ping time about 20ms. I think this should be healthy. But the problem is how long can this last.

Could it be too many users, sometimes 20+ peoples using it, and/or some applications causing network jammed? Any router setting I can do to prevent this? Or, are there routers come with reset feature where I can set it to reset every hour?

By the way, my Dlink 615 router LAN ports also connected to three wireless AP(Access Points, also Dlink product) for different floors. Are these AP causing the jammed?

A:How often I need to restart cable modem and router

It's important to make sure you have the latest firmware for that router. After updating it reset it to factory defaults and reconfigure it.

Yes, 20+ people is a pretty heavy load for a SOHO router. Note that if one user in the best of times gets 17 Mbps download 20 users with each average less than 1 Mbps at best.

I recently bought equipment to hook up a cable modem to two pc's. I've linked up the nics to a router which is linked to the cable modem via a Patch cable supplied by comcast's Self installment pack. Is this cable also a Crossover cable? as that is what is required according to the Modems manual (comcasts pack shows this 'patch' cable as connecting the modem to the nic card and not the router as they don't provide instructions for linking 2 systems. I am thinking maybe the cable isn't right as after I called Comcast they said they will be sending signals to the modem to set things up. Friends who have done this say it only took half an hour and so far it's been half a day and one at a time the modem lights flash on and off and keep on going through the same pattern then all turning off and then the process repeats. Comcast did say to wait 72 hours but I'm thinking it should be done by now (compared to friends systems).

A:Can I connect Cable modem to DSL router?

no. DSL and cable internet are two very different technologies. You'll need a standard router that you can use with any type of ISP. Then all you need is a cable modem or a DSL modem depending upon the type of service you have.

OK, I'm running a Linksys cable modem with a Belkin router. The router is a 2.4g 802.11g wireless.

The problem is just that we have 5-6 laptops running at once, two are Macs, and they're all competing for some bandwidth. The cable and router go down frequently and have to be unplugged and restarted again and again.

This especially happens when someone is watching a recorded show on our media center PC (HP), through which the router and modem operate.

Can I even explain how annoying it is to have to constantly get up and unplug and then replug in the router and modem -- or yell through the house for whomever is sitting at the computer to do it -- and then have to wait while the connection is re-established? And this is nothing to say of the content that's lost when it happens.

Anybody have any ideas about this? Do I need a new modem AND router? Do they make them so they can handle more computers?

Thank you. Much appreciated!

OK, this is my third post today...someone must have something to say about this (I hope)...

I had cable modem service at my old apartment for over 2 years without incident. We moved into a house a month ago and I have gone through 2 cable modems and 2 motherboards (with built-in NICs) in that time! The last time also fried one port on my brand new router (but the other ports are fine).

I am desperate for a surge protector to connect to the coaxial on my cable modem, but apparently there is no such animal. The store where I bought the motherboard just ran the diagnostics and told me that yes, the port is out and the NIC is bad. They will replace them both, but I am really afraid it's going to happen again. Especially if it is lightning or something that is causing this.

The tech suggested that the computer that was grounded better was the one with the problems, but he wasn't sure. My question is this:
- why is none of this happening to the other machines on the same router
- how can I insulate the troubled machine/NIC/motherboard/router from being affected by power surges in the future, and
- is there a cable modem surge protector type thing that I can buy/build whatever.

My Netgear FVS318 router is connected to an Optimum Online cable modem (dynamic IP). The router needs to be rebooted periodically (the internet connection stops). I think it is when the cable modem had gotten a new IP address. I'm not completely sure of that but it just happened and I noticed my modem a new IP address than what it had yesterday.

This happens every few days or so. The cable modem has a phone line that keeps working even when the internet is down, when I reboot the router the internet comes back up right away.

Would there be a setting in the router to help it adjust? or might there be a different problem?

I am connecting via Time Warner-Roadrunner with a Netgear CGD24G cable modem gateway.
I am always having trouble with DNS.
DNS is not able to resolve IP addresses.
DNS Server isn't responding.
Pages are not usually opening and most of the time when I click refresh, nothing is happening. Refresh button appears in 10% of a second.

I don't know how to resolve the problem. I can try connecting via USB, but I haven't found the driver for it yet. Thanks to NetGear, there is no driver on internet or in the resource CD.

The other solution I am thinking is using the D-Link DIR-615 router. I am thinking to add it to the CGD24G gateway (because DIR-615 doesn't have a coaxial cable input). They obth have as default address. How should I change the modem and router gateway addresses? Should I change the CGD24G to (which I already did actually)? When I do that, do I need to change the IP addresses

from -
to another range or leave it the same?

Do I need to change the IP addresses or the subnet mask on DIR-615 if I add it?

Is there any solution for DNS and Key Ports problem with CGD24G on a Windows 7 Ultimate x64 OS?

Does anyone have a USB Driver for CGD24G?

I hope I could make myself clear. English is not my mother tongue, and my expression of my thoughts can confuse native speakers time to time.

One of the problems you have is that router will severely limit your internet speed. I had one with the comcast connection and it dropped me from 21MBs to 6 MBs. Once I trashed that and went with comcast's modem I was back up to full speed. Seeing how you pay roadrunner, I had them when I was in TX., I would call them and tell them that you want to switch to AT&T. Not that you really are intending to but let them know this. Then tell them the problems you are having and that is the only reason you are thinking of canceling with them and switching to AT&T. Watch how fast they quickly offer to resolve your problem by sending a Tech out for free and fixing the problem for you. They key word here is you have to tell them that you are thinking of canceling with them and switching to AT&T. That should fix your problem with no headaches on your part! Post back to what they reply with you.
