WiFi Connection Issues: 5Ghz band not found? How do I determine wifi settings & limitations

Someone at the HP Global support community used some of the previous posts in this thread as a reference. It contained enough misleading information to confuse him.  

802.11 b\g\ are 2.4 GHz bandwidth only

802.11n can be 2.4 & 5  Ghz bandwith or only 2.4 Ghz.  It depends on the wireless tranceiver's capabilities and the antenna setup.

The very first first thing you need to do is to determine if your installed wifi adapter has 5 GHz capability.

Since the wifi adapter drivers are installed , finding out what it is and its capabilities should be pretty simple. 

Open the Device Manager and expand the Network adapters section. You should see a wireless adapter device with a brand and model.

Write down the brand and model information and use it in a Google or Bing search as follows:

Brand and model number (substitute your adapter's brand and model number) and the word specifications.  

The specifications that the search returns will tell you in which band the wifi adapter operates.

Look for 2.4 and 5Ghz in the bandwidth operation specification. If you only see 2.4 Ghz, then now you know that 5GHz operation is not possible. 

An alternative, now that you are armed with the brand and model information, is to go to the wifi adapter's company website and search for information there.

There is no amount of tweaking in the adapter properties settings that will enable a wifi adapter that is only capable of 2.4 GHz operation, to operate in the 5Ghz band.

A 2.4 Ghz only capable wifi adapter will not even recognize the presence of SSID's that are broadcasting on 5Ghz.

Mine says 802.11d      I have never heard of 802.11d????      My computer worked fine before upgrading from Windows 8.1 to Windows 10.  I am so frustrated that I am just about ready to go back to 8.1. 

I just bought new laptop with windows 10 already installed and it is supposed to be dual band 802.11 b/g/n, but it too doesn't see the 5 Ghz band.  All my smartphones see the 5Ghz band as did my computer that I upgraded to 10 before the upgrade.

I have the latest Linksys router, purchased just a few months ago.

My Network adapter onboard this laptop is a Realtek  RTL8188EE  wireless lan  802.11n  PCI-E-NIC

When I click on update the Network adapter listed above, it says It is up to date.

Please help

Hi Richard,

I have searched for information about the wireless adapter installed in your computer and found that your wireless adapter has 802.11n standard, which supports 5GHz bandwidth.

unfortunately, I was unable to find the Wireless adapter make and model. Let us know the make and model of the Wireless adapter.

While you reply, check if these settings help.

1. Go to Desktop mode
2. Select Charms > Settings > PC Info
3. Click Device Manager (located in the top left of screen)
4. Click the > sign to expand the Network adapters entry.
5. Right-click the wireless adapter and click Properties.
6. Click the Advanced tab, click 802.11n mode, under value Select Enable.

Hope the information provided is helpful. Do reply, if you need further help.

This fix does not work with a Toshiba laptop running Windows 8.2. Was able to enable 802.11n, the 5 g network is not found.

I did  all these steps and can still only see my 2g wifi on my laptop. I have a  acer aspire e17
