Hi, what's the model number and hardware version of your adapter? Did you try the driver on our official website?

@Kevin_Z I am also confused in this regard, but there are wiresless routers that are manufactured by TP Link and this is the main reason behind my research.

 

Moreover on the other side the TP links connectivity to the android devices also so powerful

  Hi All.

 

I've experienced the same issue. Seems happened with a Windows update I couldn't identify.

My solution was to update manually the drivers in the device manager using the following drivers (latest, dated from 2018) from the Realtek web page:

 

https://www.realtek.com/en/component/zoo/category/rtl8811au-software

 

Attached the drivers only for Windows 10, in case the link stops working.

 

After installing it T2U was able to find and connect to 5GHz network independent of the channel (tested on channel 165 40Mhz)

Hello everyone, 

 

If your Wi-Fi network adapter can see 5Ghz Wi-Fi but not able to connect to the 5Ghz Wi-Fi band, here are some basic troubleshooting tips that you could give it a try:

 

1. Please make sure you have tried the latest TP-Link official driver for the adapter.

https://www.tp-link.com/support/download/

2. Confirm you have put in the correct 5Ghz Wi-Fi password 

3. Delete Wi-Fi profile and reconnect to the Wi-Fi network

How to connect to wireless networks and remove its profile on Windows 10

4. Try a different 5Ghz Wi-Fi channel on your router to 5Ghz Channel 36,40,44 or 48. 

5. Confirm other network devices can connect to the same 5Ghz Wi-Fi when manually put in the 5Ghz Wi-Fi password

6. For some adapters,  try this chipset driver for your TP-Link USB adapter Realtek Chipset Driver for Archer T2U(Nano/ Plus)/T3U(Nano/ Plus)/T4U(Plus)/T4UH/T9UH (Win7/Win10)

 

As this topic is pretty old and seems to be solved by the Win10 OS version released after 2020 from Microsoft end,  this topic will be closed.

If you need further help, please Start a New Thread for the network adapter, you may share a photo of the error message, model of router and the steps you've tried.

If you are unable to connect to the 5GHz network with your T2U/T2UH wireless adapter after upgrading to Windows 10, there are a few things you can try to resolve the issue:

  1. Make sure your wireless adapter drivers are up to date: Go to the manufacturer's website and download the latest drivers for your T2U/T2UH wireless adapter. Install the drivers and try connecting to the 5GHz network again.

  2. Check if your wireless adapter supports the 5GHz band: Some wireless adapters do not support the 5GHz band. Check the specifications of your T2U/T2UH adapter to make sure it supports the 5GHz band.

  3. Check if your wireless router supports the 5GHz band: Make sure that your wireless router supports the 5GHz band. If it does not, you will not be able to connect to the 5GHz network.

  4. Try resetting your network settings: Open the Command Prompt as an administrator and type the following commands one by one: ipconfig /release ipconfig /renew netsh winsock reset netsh int ip reset Restart your computer and try connecting to the 5GHz network again.

  5. Try changing the wireless channel: Sometimes the wireless channel can interfere with the 5GHz network. Access your router's settings and change the wireless channel to a different one and see if that helps.

  6. Disable and re-enable the wireless adapter: Go to the Device Manager, find the T2U/T2UH wireless adapter, right-click on it, and select "Disable." Wait a few seconds and then right-click on it again and select "Enable." Try connecting to the 5GHz network again.

When i was using inshto mod apk same happeining with me but this method help to resolve my issue

If none of these steps help, you may want to consider contacting the manufacturer for further assistance or purchasing a different wireless adapter that is compatible with the 5GHz band
