Laptop can't connect to 2.4Ghz frequencies, only 5Ghz frequencies

Q: Laptop can't connect to 2.4Ghz frequencies, only 5Ghz frequencies

My Windows 8.1 laptop, fitted with an Intel Centrino Ultimate-N 6300 AGN wireless adapter, suddenly stopped automatically connecting to my router a few months ago. I attempted to connect wirelessly to multiple other routers, all to no avail. My laptop could only connect through an ethernet cable/tethered hotspot. I then moved houses and got the internet set up on a new provider and suddenly my laptop could connect wirelessly again! Sadly, after trying to connect to my university's wi-fi, I found out that the laptop wasn't fixed, it was simply able to connect to my new 5Ghz internet but still had trouble connecting to 2.4Ghz access points.

I've tried everything I can to fix this as my laptop is too vital to my studies for me to be without it even for a short period of time, therefore sending it off for diagnostic and repairs is out of the question for now. So far I have tried:

Installing the latest Windows 8.1 drivers for the card (currently on v.15.14.0.2)
Replacing the wireless card with a new one (same make and model)
A complete, fresh re-installation of Windows 8.1

Running out of ideas on what to try and so turning to the community for help. Even if you're not sure of a fix, determining the problem itself would also be a big help. Thanks much in advance!

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Try the latest wireless driver from the laptop manufacturer's web site.

If that doesn't work then try the latest driver directly from Intel's site.

I want to upgrade my home network to support HD streaming over Wifi. I am considering getting an 802.11ac router and replacing my laptops Wifi network card with one that supports the new Wifi 802.11ac standard.

On my home network I want to connect a TV set top box to the router over Cat6 but my laptop is the only device that will be connecting over Wifi. I have a Dell Inspiron 7520 laptop. It has an Intel Centrino Wireless-N 2230 Wifi card which supports dual stream but only one band: 2.4Ghz.

It looks like my laptop only has two internal antenna cables and for this reason I am thinking I cannot avail of triple stream Wifi-N 450Mb/s + 450Mb/s on a simultaneous dual band N900 router. I am stuck with a theoretical max of 300Mb/s on 2.4Ghz under Wifi-N and/or 866Mb/s on 5Ghz under Wifi-AC.

Here are my questions:

1. If I get a simultaneous dual band router can my laptop stream an HD movie on the 5Ghz band and at the same time download say a Youtube video on the 2.4Ghz band? I ask that because I'd like to get a such a router and preserve every ounce of bandwidth on its 5Ghz band for streaming movies from the set top box to my laptop... not have to share it for web browsing needs.

2. Would it be a better solution, or even possible, to install a third internal antenna in my laptop and get a triple stream 802.11n class Wifi card (such as the Intel Centrino Ultimate-N 6300) and Wifi-N Class router OR should I buy an 802.11ac router and get the better bandwidth it offers...

A:Can my Laptop simultaneously connect to a 2.4Ghz & 5Ghz Wifi network?

You can stream HD movies fine at 150Mbps or even less but it depends on how much of the bandwidth is being used by your neighbors. This can be a big problem in some areas. You won't be able to use both frequency's at once.

Finding the best clean channels to use are what matters most on 2.4 GHz, channel bonding comes in handy sometimes but works best when the channels are mostly clear.

5Ghz is better in this respect because hardly anyone is using it so you tend to get all the bandwidth to yourself but the drawback with 5GHz frequency is that it won't go through walls worth a darn so it's really only useful for open area's outdoors or for large rooms.

I'm running the Asus AC66U router and the Asus PCI-e AC66 NIC which usually runs about 877.5-1.1 Gb. I can stream multiple YouTube video's while watching movies although I could also do this using the 2.4GHz frequency at 300Mbps.

I bought a D-link DIR 825 router, having read claims that, on ONE wireless network, it runs 2.4GHz and 5GHz frequencies SIMULTANEOUSLY, and somehow determines for itself how to apply those frequencies to what I'm trying to achieve on the network.

D-link's own support contact denies that this is possible, which appears to contradict D-link's claims about the DIR 825 and what I have read about the product online. They are saying that, indeed, you can use both frequencies at once, but on DIFFERENT machines, i.e. that a single machine cannot be simultaenously connected to both frequencies.

For the life of me, I can't see how to connect to both frequencies at the same time. When setting the DIR 825 up using the relevant wizards, it treats the 2.4GHz and 5GHz as two separate wireless networks. I can then connect each of my computers to one or the other, but apparently not both.

Any help would be enormously appreciated!
 

A:D-LINK DIR 825: how to connect to 2.4GHz and 5GHz simultaneously

They imply two separate transceiver circuits insted of just one that switches transmitting frequency.
Traffic for the 5GHz will be faster with a separate SSID and transmitter., since you will cut out the delays caused by the transceiver switching frequency and handling the slower 2.4GHz traffic.

Your problem is that the computer's wireless adapter can only connect to one SSID and IP address.
You can set up alternate connections for your wireless adapter using a different SSID and IP address for the separate frequencies and switch back and forth, but this is not what you want.

To connect your computer the way you want you would need to have two wireless adapters on the computer.
Set one up using the 2.4GHz SSID and IP address as a default for general wirless use.

Setup the other one using the 5GHz SSID and IP address.

You would need to then set up routing on your computer so that programs that need to use the 5GHz will connect to it.

Hey all, this is my first post here, its great to be here!

Anyways,

I just purchased a new motherboard, cpu, and memory (wanted to finally switch from AMD)
I purchased the Core 2 Quad 6600, Gigabyte P35-DS3P, and 2x1GB of Ballistix Tracer
I have Windows XP Pro w/ all current updates

The speed of the memory is DDR2 1066 (PC2 8500)
and my motherboard supports DDR2 1066 and dual channel memory

When I run CPU-Z it says Max Bandwith for each stick is PC2-6400 (400mHz)
The timings are :
Frequency 533mHz, CAS Latency 5

is the frequency correct? it seems slower, i mean my old pc-3200 memory was running at 400mHz CAS latency 2.5.

Just wondering what I would need to change in the BIOS, this mobo's got great OC'ing tools

Thanks for looking appreciate any help!

A:RAM Frequencies Problem

Indeed the board does but as is shown

Dual Channel Memory Architecture
Supports Intel® Extreme Memory Profile (XMP)
* Hyper DIMM support is subject to the physical characteristics of individual CPUs.
* Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists

all except 2400 and 2133 are OC

Your processor
https://ark.intel.com/products/97128/Intel-Core-i7-7700-Processor-8M-Cache-up-to-4_20-GHz
Memory Types DDR4-2133/2400, DDR3L-1333/1600 @ 1.35V
supports those none OC at SPD - serial presence detect

So your ram although I do not know which exact model of Vengeance it is - as explained in your motherboard manual must when OC not only be configured alone for ram but as part of the sophisticated procedure on that motherboard - where if you wish you can simply use the 5 step automated process explained on your manual
Have you checked if your Corsair ram is on the QVL list from Asus
https://www.asus.com/uk/Motherboards/ROG-STRIX-Z270E-GAMING/HelpDesk_QVL/
That list cannot of course list all ram that will work with that board, but what is listed has been tested by Asus

This presumes the problem existed - not only on one or two games but across the board

Is it possible to pick up radio frequencies and interference on computers? I opened my Windows Media Player today and heard, very quietly, a talk radio show and was flabbergasted. It has never, ever, ever happened before. I don't listen to internet radio so I don't know what it could be. Completely dumbfounded over here.

A:Radio frequencies?

Yes, it is possible. Computers are an FCC Class 15, sub-part B product, which means that while they may not cause interference in other products, they must accept any interference caused by something else. That's why your PC can pick up talk radio. You were either picking up a local radio station, or something nearby was radiating that signal.

That's it in layman's terms. You can look up the officialese in your owner's manual if you like.

A couple of months ago, I built a capable gaming rig (E8500, ATi HD4850, 4GB PC-6400 RAM on a Gigabyte EP35-DS3L with Vista x64), and set it up. It was my first time building a computer from scratch on my own, but I made it and recently overclocked my CPU.

I intended to overclock it to 3.6GHz, and it looked like that in the BIOS but using CPU-Z, it reported it at 6 x 380.0 MHz or 2280 MHz. It does change to the 3.6GHz at times in the program, but never in the output file. I'm assuming this is because of some energy saving thing? The mobo did come with an energy saving program, but I disabled it and stopped it from starting on boot, but I guess I may have not gotten rid of it properly.

CPU-Z also reports that my RAM is PC-5300 (333 MHz x 2), even though the RAM was sealed (at least, it looked like it). My CPU-Z output file is attached, if you want to take a look at it.

Regards,
Cal

Good day Win7 Community,

This is my first post on here, as many users, I come here because I am having an issue.

I bought my new computer at friday.
I began installing my desired programs and games.
But as I progressed I found out something was going on with my sound.

I own a 5.1 surround sound speaker set so I'd like to use it, I believe I have stereo sound on it right now because I want my speakers to have sound all the time instead of having either music or voice-only.

On to the issue;

At first, I used my audio outputs of my motherboard, but that didn't really work well with my speaker set.
So I got my old 5.1 surround card (PCI) out and installed it into my new computer and plugged my speaker set, I could now use all 5 speakers.

I uninstalled the motherboard sound drivers and installed the sound card ones.
Fiddled with the settings the way I like it (sound volumes on each speaker)

I got it all working.. only, with youtube,WMP,VLC Mediaplyer, whatever produces sound.
When a high frequentie sound comes along, it gets scrambled which really ruins my fun of my new computer.

List of hardware/Software:

Motherboard: ASUS P8H67
Sound Card: Trust SC-5100 5.1 Surround Sound Card

Motherboard Sound Drivers: Realtek High Definition Audio Driver

Sound Card Driver: Trust 5.1 Soundcard 14319

Recap:
I uninstalled Realtek and installed the trust 5.1 sound card drivers.
I tried fiddling with WMP's settings etc. but no luck so far.

I hope someone can assist me in this struggle.

I thought that 5Ghz would always beat 2.4Ghz hands down on everything apart from distance. With this in mind I set my router to broadcast at 5Ghz and thought that my wifi would be much better as a result,but it wasn't.

I have my router and my PC in the same room a few meters from each other, and while I was using 2.4Ghz I would always get 90% signal strength,but when I changed to 5Ghz instead of my signal getting to 100% it went to 70%? My router is capable of both 2.4Ghz and 5Ghz so why is it that 2.4Ghz is better than 5Ghz when I have been told that it should be the other way around?

I was told that microwaves, cordless telephones and other electronic devices use the 2.4Ghz frequency range and this causes intereference and as such causes a loss of signal.

5Ghz I was told is free of other electronic noise so it is much better and you will always get a stronger signal. The one thing which I was told that made 2.4Ghz better than 5Ghz was the fact that legal restrictions on 5Ghz routers meant that the amount of power they could use to output a signal meant they were not so good over long distances, and in some countries it was even illegal to use 5Ghz frequency.

A:2.4Ghz vs 5Ghz puzzle?

The higher the frequency, the more power it takes to emit said frequency in comparison to lower frequencies. If you have a decent router, however, it shouldn't make a difference which band you transmit. Just because the router CAN use the 5GHz band doesn't mean it'll operate best on it.

I have a Asus PCE-AC68 wireless card and can connect to my router TG799vacxtream on 2.4GHz, but I cannot see the 5GHz. That's strange, because I see it on my laptop running Windows 10 and on my iPhone and iPad. Only the Asus card cannot see the 5GHz. When I contacted Asus they put the blame on Windows latest update, and when I contacted Microsoft the put the blame on Asus and that they must update their driver. I contacted Asus again and asked for a date to have a updated driver but they can't tell. Strange policy?

I have a router on one side of my house that is broadcasting 2.4GHz. I have an extender on the other side of the house that is connected to the router with 2.4GHz, but it is broadcasting 5GHz. Both the router and the extender have the same SSID and password. Is this a suitable setup if I want to roam the house on the same network?

Thanks for the help!

I actually just disabled 5GHz completly around the house and both the router and the extender are on 2.4 and have the same SSID and password. Is there anything else I need to do to make roaming the house a smooth process?

I have an issue with the Wifi connection, but it is only problematic when I'm connected to 2.4Ghz networks.My laptop is running with a Intel(R) Dual Band Wireless-AC 8260. When connected to 5Ghz networks no problem at all, but when the laptops connects to 2.4Ghz networks the internet either does not work at all, or it is at such a low speed it is impossible to be productive. Especially if I'm not near the router as it then automatically shifts to 2.4GHz due to better signal. The issue is present with any network - not just my home network. I have no issues with other devices (PC's, Mac's and smartphones) at home; only this specific laptop. I have chosen 5Ghz as the prefered option, and the driver is up to date. What to do?

Hi everyone!

This is my first post here, so apologies if I am not providing the correct/enough information at the outset.

I will be happy to provide as much information and in a timely manner as prompted.

The crux of the issue, is that recently the 2.4ghz and 5ghz connections in my home are only working one at a time. Meaning, I can be connected to 2.4ghz, but am unable to disconnect the same device from 2.4ghz and connect to my 5ghz network if I chose to. This is not a device compatibility thing, as an example I have experienced this on an iPhone XS.

Now, the interesting thing, is that when connected to my 2.4ghz for example, the connection will frequently drop, and then if I select 5ghz, my connection to the internet will be successful.

If I were to go back to 2.4ghz it will not connect.

After a while the 5ghz will drop and I will revert back to 2.4ghz.

It is incredibly obnoxious.

Please help!
 

A:Wi-Fi Connection Flipping from 2.4ghz to 5ghz

It's either a problem with the radio in your router, or a problem with the networking components of your laptop. Borrow a router from a friend and see if the problem continues, if your friend's router works, then the problem is isolated to your router - buy a new one. If your friend's router doesn't work, then it is a problem with your laptop.

the belkin router is connected to a virgin router.
thier is a setting on the belkin router, which allows you to use it as an 'access point'.

all 4 devices can connect perfectly. and use programs like 'VLC remote' perfectly.

but when it comes to itunes on the pc, after setting all the apropriate settings on itunes,
itunes is unable to see all 4 devices for 'wireless syncing'.

ive come to a hault, and stuck :/

Good morning!

1. Background. I recently purchased a "Toshiba A505-S6017" laptop (Intel Core i5/4GB RAM/500GB HDD) with Windows 7, 64-bit, Premium Home edition installed: (1) I have a fully functioning home network with 4 (other) XP, 32-bit, PC nodes. (2) My router is a "Netgear Rangemax Dual Band Wireless-N Router WNDR3300." (3) My new laptop has an internal "Realtek RTL819 Wireless LAN, 302.11n b/g/n(draft) PCE-E NIC," (4) My laptop tranceiver is "Microsoft 2.4GHz, V1.0" (5) I have two wireless networks on the router, one for the 2.4, the other for the 5Ghz and can switch between the two, as desired.

2. Problem. Windows 7 found the 2.4GHz, no sweat, but does not see the 5GHz. I want 5GHz access since am worried about my 2.4GHz and mutual interference with household cordless phones, microwave, etc. which also use 2.4 -- plus, 5GHz is preferred for the speed/modernization advantages.

3. Actions to-date. I have followed Windows 7 procedures for automatic home-network detection, in many ways. I have researched (all/most?) involved OEMs' documentation, forums, and Internet-wide Google queries. I can find no solution or suggestions for the problem.

I am desperate to find a solution, as I need to set up access to my other computers from my laptop. I am considering upgrading my older PC's to Windows 7, but first need to address this issue. Can you help analyze and solve this?

Thanks so much for any consideration y... Read more

Hello Windows Gurus,

I'm starting to design a 5GHz Wireless Networks that will work together with an 2.4Ghz during the tests and transition phase. In order to keep the same configuration into the clients, we are choosing the same SSID, so we do not have to go one be one and change the machine configuration.

My question is, If there are two WLAN, one with 2.4Ghz and another with 5Ghz with the same SSID, how Windows will choose to which frequency to connect?! To the 2.4Ghz (the default frequency for most APs) or will it try to connect to the 5Ghz (Faster and Less Interference)?!

I also checked and the computers does have Wireless card that works with 5Ghz frequency.

A:Which wireless frequency Windows 7 considers the best? 2.4Ghz / 5Ghz?

Welcome to Seven Forums,

When you said two WLAN, are there 2 WAPs? One operates at 2.4GHz and another one at 5GHz? Perhaps, you're talking about a Dual Band Router that supports both Standards (11n and 11b/g)?

If your Wi-Fi adapters support both and they are configured with a mixed mode then they should be able to connect to the 5GHz band. The wireless mode can also be changed from your router and set it to just '5GHz' if you'd like all the wireless network devices to utilize the 5GHz.
FYI....802.11n supports both 2.4 and 5GHz clients but you must consider 5GHz than the 2.4GHz if you'd like to achieve a great network performance.

Hi,

I have a N600 Wireless Dual Band Router model WNDR3400. My question(s) is that if I connect with a wired cable, will I be connected to the 5ghz and avoid interference with those on the 2.4ghz connection?

For example, I have a wired connection with my Playstation 3 but i believe the Playstation 3 incapable of detecting the 5ghz when I do a wireless scan. Does this mean when I connect with a wired cable with the ps3 I use the 2.4ghz connection with other users and getting interference if they're doing something like streaming?

And finally, if my Laptop is unable to detect the 5.ghz connection does that mean I need some sort of adapter? Or does it have to do something with the settings. Its enabled and is on the default channel.
[Sorry one more question, where do I go to see who is currently using the internet connection in the setup]

Hi, I have a netgear WNDR3400 100nar router, dual band, 2.4ghz and 5ghz. I set up 2 connections. On the 2.4ghz I set up a WEP connection with 64 bit encryption for my wireless repeater (WNR2000). On the 5ghz i set up WPA2 for regular use. Unfortunately my computer does not support 5ghz or atleast i dont think it does. My samsung tv picks up the 5ghz so I connected to that, the macbook pro connects to the 5ghz. The other computer I want on the 2.4 ghz with the repeater. Hardlined via ethernet anything and everything works. For some reason 2.4ghz wont connect wirelessly and does not even give me the option to enter the hex key. just says unable to connect. the 2.4 doesn't work on anything (currently the repeater is offline until I can fix this issue). Infact, ignore the repeater info. I think there is a problem with the distribution of the IP addresses. Could they be overlapping between the 2.4 and the 5? The next item on the network (tv) using 5ghz, occupies sequence 2 under the ip address....whatever the default is it would occupy 192.168.1.2. I have reformatted my computer, uninstalled and reinstalled network drivers, as much as I could do with the computer itself so I'm assuming it is the router. I've disconnected it and reconnected it, reset it, redone the whole network multiple times, renewed the IP address. What is going on? Can anyone help me please.

This is a problem that has persisted under fresh installs of Windows 7 and Windows 8. My laptop (Samsung Series 9) won't connect to any network that is operating on the 2.4GHz band. It shows up as a normal network, but trying to connect always ends with the error message: "Can't connect to this network."

The WiFi card is an Intel Centrino 6300. Before someone tells me to go connect to a different network, I've already tried several.

Have you tried installing the latest Windows 8 drivers for the Intel Centrino 6300?

The latest ones are dated 1-20-13 so they are recently updated and should work for you.

Hi all, this is my first post so I really appreciate all of the help and I can't tell you how much I've benefitted from the things I've read while lurking here over the last few days. Now, on to the show...

I have an HP workstation with a Q35 based mother board that had a 2.4GHz Core 2 Duo in it (E6550), and I wanted to put the processor into my new rig, but still want to use the old comp. I have a Cedar Mill core Pentium 4 3.4GHz HT that's also socket 775 and I thought I'd just stick that in the HP since it doesn't need the better processor. Now, when I try to boot the HP, I get a couple of beeps and the fan just goes on overdrive and stays that way until I shut the thing off, but it never boots.

What's weird is that I can stick the Core 2 Duo back in and everything boots up just fine, but the thing just hates on that P4 like no tomorrow. Now I've used the P4 in my new rig just to make sure it wasn't shot, and it works like a charm. It's just in that workstation with the Q35 mother board that I'm getting nowhere. Any thoughts?
 

A:Cedar Mill P4 3.4Ghz in Q35 mobo won't boot. Swapped in for C2D E6650 2.4Ghz

Your workstation motherboard probably does not support that P4 processor. Just because it is socket 775 doesn't mean it is compatible.
