First of all it is not duplicated I tried other solutions but not working.

OS: Ubuntu 18.04 LTS

Output of lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 148f:5372 Ralink Technology, Corp. RT5372 Wireless Adapter
Bus 001 Device 002: ID 045e:07fd Microsoft Corp. Nano Transceiver 1.1
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I was facing the issue not showing the 5G wifi so I follow No wifi option on Ubuntu (18.04 and 16.04) but now it is not showing any wifi option and message is 'No Wi-Fi Adapter Found' is coming.

Output of commands:

  • What about "Ralink Technology, Corp. RT5372 Wireless Adapter"? – mikewhatever Sep 17 '18 at 2:07
  • Your device is covered by the driver rt2800usb that is already included in Ubuntu 18.04. Please show us: sudo modprobe rt2800usb and also: rfkill list all – chili555 Sep 17 '18 at 2:11
  • @chili555 both commands output is nothing. – Abbas Sep 17 '18 at 2:15
  • How about: dmesg | grep rt2 – chili555 Sep 17 '18 at 2:16
  • @chili555 I have added the output in the question – Abbas Sep 17 '18 at 2:18
