Model: Archer T4E  
Hardware Version: V1
Firmware Version: 2024.0.2.101

I just installed the Archer T4E AC 1200 Wireless PCIe adapter and it is unable to connect to my 5GHz WiFi network.

I am running 65-bit Windows 10 Home.

I tried the already-installed Windows 10 driver, the TP-Link driver that came with the adapter, and the driver here on TP-Link's website.

None of these drivers enabled me to connected to my 5GHz network. My wireless router is a TP-Link Archer C7 V1 with firmware 3.15.1 Build 141204 Rel.39308n.

 

I read in a few places that the wireless network has to be setup correctly (e.g. Channel 40) however this has not worked either. I've tried several different things but I'm just guessing. Is there a solution to this problem?

Please advise.

 

Thank you!

@tchari  

For your concern, you can refer to the instruction below to do some troubleshooting.

https://www.tp-link.com/support/faq/2253/


When you try to connect to the 5G wifi, can you see any error message? If so, please send us a screenshot of the error message. Can you connect to the 2.4G wifi?

 

Please try to use this adapter on another slot or another computer to test.

Have a nice day.

There is no error code for me. I just cannot see the Wi-Fi network that is on 5GHz for my Arhcer T4U adapter. Your tutorials have been tried but they didnt address my issue.
