Model: TL-WN823N  
Hardware Version: V3
Firmware Version:

The TL-WN823N refuses to connect to my WiFi network powered by Deco X20 (both with fast roaming turned off and on) when plugged into my desktop PC. It also won't connect to my phone network when it's serving as a hotspot (again, both with compatibility mode turned on and off). The network is functioning fine for all other devices.

 

I've tried:

  1. The latest driver from the TP-link website ( 2018-11-09 )
  2. The latest driver Windows finds for the adapter (7/29/2019)
  3. And using the WPS button to connect (It keeps seeking and "syncronizing" until it times out).

 

The error message is "Can't connect to this network".

 

I should say, it did actually work for a brief moment yesterday after one of the many cycles of uninstalling and reinstalling drivers, but a computer reboot killed it again.

Any help to fix this would be greatly appreciated

Thanks for the suggestions. I did get it to work by plugging the dongle into the front USB of my desktop PC. Using the USB on the back of the motherboard was causing the problem (I haven't tested all the ports back there, but the one that was free didn't work).
 

The network is WPA2-PSK [AES & TKIP], but that ought not matter as it's working right now.

@Arn_Thor Good day, 

 

Please check if Deco X20 is using WPA3 as wireless security, if yes, please change to WPA2/ WPA2 as wireless security type from Deco app-- Wireless settings. 

Double-check the wireless Wi-Fi password on Deco

Turn Off 5Ghz wifi and run 2.4Ghz wifi only, or you could create a Guest 2.4Ghz wifi and see if adapter could connect to it or not.

Delete the profile on your PC and reconnect to Deco or Hotspot WiFi

If you are using Win10, please also try this latest public driver for TL-WN823N:
