Windows 10: Failing to see 5GHZ SSID wifi network

Hello,

Just wondered if anybody can help me sort out this problem which I have.


I have Bt infinity 2 with a BT hub 5 router which enables me to have either a 2.4 GHZ or a 5GHZ wifi my problem is that it see's and connects to the 2.4GHZ but does not see the 5GHZ one , surely windows should see all network close or within range???

any help would be greatly appreciated .

Thanks

how to change 2.4gh to 5gh wifi

Hi Kaleshas,

Just to confirm:

• Can your phone actually "see" the 5GHz SSID and is unable to connect OR it can't detect the 5GHz SSID at all?
• Did you get any error message when you tried connecting?
• Are there other devices connected to the 5GHz network of your wifi router (and presumably working)?
• Have you tried connecting the phone to other 5GHz wifi?

Good day!

 

Lumia 950 fails to connect to WiFi while Bluetooth is enabled

Hi again

I have a better understanding now about how my new Router has "solved" the issue. It hasn't. But it does provide a workaround.

• My old router had both 2.4GHz and 5GHz WiFi but they were broadcast using the same SSID name.
  

• My new router also has both 2.4GHz and 5GHz but allows them to have separate SSIDs.

With the new router, I set up my Lumia 950 to connect to both 2.4GHz and 5GHz networks, but left it with the 5GHz network connected when I did my testing.

I went out last night and when I came home, the phone connected to the 2.4GHz WiFi and the issue "returned" (it had never really went away). So, I made my phone forget the 2.4GHz WiFi and so now it only connects to the 5GHz WiFi.

The "solution" I have with the new router is to not use 2.4GHz WiFi. This then avoids the clash with Bluetooth (which also uses 2.4GHz frequency range).

-----------

The old router did not allow me to turn off 2.4GHz WiFi (I could turn off 5GHz) and did not allow me to specifically tell a device to connect to 5GHz.

This also explains how sometimes (with the old router) when I would come home with Bluetooth turned on and my phone would seem to work for a while before failing. It would have been connecting to 5GHz initially, until it lost the 5GHz network at some stage
and then tried to reconnect to 2.4GHz and failed.

So if your router can have separate SSIDs for the two ranges use that feature. Then set your phone to only use 5GHz.

The problem remains that Bluetooth and 2.4GHz WiFi cannot work together.

Hi there

I doubt whether it's BT's Router that's the problem unless it's not configured correctly.

Two things

First - does your device that's using Wifi have 5GHZ capability - if it doesn't then tough --no go. Note also some wi-fi extenders can't "See" 5GHZ networks either so if using an extender check that.

Second - does your BT router have simultaneous (optional) transmission of both 5GHZ and 2.4GHZ or do you have to choose one or the other.

Where I am (a long way from BT !!!!) I have proper Fibre Optic Internet all the way -- no copper - and the wi-fi box allows transmission of both 5GHZ and 2.4GHZ simultaneously - I have both enabled as some older devices can't see 5GHZ band.

If you have a recent mobile phone check if that can see the 5GHZ network. Most smart phones are new enough to support 5GHZ wi-fi.

If all else fails check Router settings --log on with a bit of LAN cable if you can't do it via wifi --addresses are usually 192.168.x.1 where x is normally 0, 1,or 2 - router documentation should give you that. Admin password / pin / other credentials are usually stuck on the bottom of the box but should be with your contract.

If you can get 5GHZ band to work then the wifi will have a maximum theoretical throughput with current protocols of 433 Mb/s -- should be fast enough for you !!!!.

I've replaced all my long LAN cables over the house as this speed is perfectly OK -- I have 2 NAS boxes with no wi-fi but use a small piece of lan cable to connect to "Ethernet-->wifi" bridge router operating on 5GHZ band. The NAS boxes think they are on LAN but are actually on 5GHZ band. Moved all these from living area to hidden well out of the way. 5GHZ band is fine for fast wi-fi. !!

Firstly Thanks for you reply Jimbo... As far as I know that it does operate both 2.4 and 5 GHZ at the same time, ( That is why they tell you to rename the 5ghz one so that you can see the difference)

I personally thought that windows should see all networks within range even though it couldn't connect to it they still should be able to see them.

My Samsung does see the 5GHZ network and is able to connect as does my sky box. ??

Thanks,

Sam

 

Hi there

I think you've answered your own question here.
If the Wifi card can't handle the 5GHZ signal it won't see it -- this isn't a Windows problem - it seems it's your computer hardware. The Wifi card is actually a simple Radio receiver plus transmitter.

The easiest way of putting it is for example to imagine you have an FM radio (88.7 - 108 Mhz) but there's a test station operating on 120 MHZ -- your radio wouldn't even be aware of its existence.

The Samsung phone shows your 5GHZ signal is working correctly. You will either have to get a USB 5GHZ wifi dongle or put up with the 2.4 GHZ band when using the computer -- that's the way it is -- hardware isn't compatible with 5GHZ wifi.

Your hardware (network adapter) has to support dual band. I'm betting the WiFi network adapter in your computer is only a single band network adapter and, therefore, not physically capable of receiving the 5 GHZ band.

 

Others are probably correct - you're card doesn't support 5G
You might need a driver update - can't tell because your system specs are slim.
What is the exact model? Sony Vaio what?
If not a driver, your model # will tell members IF the card supports 5G

 

Plus 5 ghz is typically faster because most devices are not dual band and they have to share bandwidth. Also 5 ghz doesn't handle walls as well as 2.5 ghz. If you have walls in between the router and PC that could be an issue also.

 

Thanks for your reply,

Here is a link to my model of sony vaio

This:

would lead me to conclude that the laptop only has a single band WiFi adapter. Is there a specific model WiFi adapter listed under Network Adapters in Device Manager?

 

Thanks, that made it easy *Wink ... sort of

The only hard info came form the manual
Page 134: User Guide: VPCE Series (PDF)

Sooo, if you have a select model, you should see the 5G setting in VAIO Smart Network

If VAIO Smart Network did not carry over to Win10, you'll have to poke around in the network adapter configuration - might be under Radios

Hi there

for 5GHZ band adapter has to support ac protocol.

Cheers

Most likely your adapter is not 5 ghz capable. netsh wlan show all in a Command window will show you what your adapter is capable of. It should show 2.4/5 ghz if it is capable of it.
