@Bestieee You computer may have switched to the 2.4Ghz as the 5Ghz signal may have dropped. Look at your available Wi-Fi networks and see if 5Ghz is visible. If so, just connect back to the 5Ghz Wi-Fi. If not, use a different device like a cell phone to verify if the 5Ghz signal is being broadcasted by your router or not.

I couldn't connect to 5Ghz for several times. And it still doesn't WORK. On my phone, it still connects to TP-LINK 5Ghz. So PLEASE give me something else to fix my adapter please.

You just have to forget the Wi-Fi network, what ever profile your computer saved is not working. When you connect again it will prompt you for the wireless password again.

Hi,

 

Hope this works for you - I am in the United Kingdom. Windows 10 home edition, all current updates applied as of 13.07.19

 

Mine worked fine until I swapped my laptop HHD for a SDD. Then all ok with 2.4Ghz, but no 5Ghz showing.

 

So I swapped the drives back and hey presto 5Ghz worked!  So I wrote down all the settings I could find, then swapped the drives back over. 5Ghz not working. So I changed the settings to mirror those that worked on the HDD and hey presto, I now have 5Ghz.  Here are the settings:

 

Driver version: 5.1.34.0

 

Laptops buit in wifi and ethernet adapters = disable

 

In the Archer adapter properties:

 

All boxes ticked apart from Microsoft adapter multiplexor protocol.

 

AP Mode Force = disable

Channel Mode = 2.4 & 5Ghz

Country region 2.4 = #1 (1-13)

Country region 5 = # (36-140)

IEE802.11n = enable

Multimedia = disable

Prefer 5g = enable

Radio = enable

Roaming = disable

Selectice suspend = enable

Selective idle timeout = 5

 

Also ensure Hotspot 2.0 use online signup to get connected = On

 

Fingers crossed for you!

 

S
