Hello community I am new here.
I recently faced issue with D’link dwa 131 Rev E wireless adapter.
It would connect to wifi on my laptop but will not work on my Desktop.
On desktop, it shows SSID but cannot connect it. Further debugging and searching on google i did not find anything relevant. Now finally figuring out solution and i thought i might share it with community.
If you happen to buy DWA 131 E or any rtl8192 based usb wifi adapter and cannot connect to any wifi,
first check if you are failing authentication with following command,
dmesg | grep 'authentication with'
If you have similar output as follows,
[ 812.271835] wlp0s20u12: authentication with 0c:37:47:bd:6e:ae timed out
[ 814.919915] wlp0s20u12: authentication with 0c:37:47:bd:6e:ae timed out
[ 825.568240] wlp0s20u12: authentication with 0c:37:47:bd:6e:ae timed out
You just have to enable XHCI Handoff and EHCI Handoff in BIOS/UEFI settings and it will start working.
Request to mods, this is my first ever post on discourse and it says i am not allowed to create new post in support and help section. Please dont ban me i just want to help so no one else has to spend a sunday fixing their wifi.
