I am currently using Ubuntu 22.04. I have a USB type WiFi adaptor to connect to a wireless network, but on enabling the WiFi I do not see any network available to connect with. I have tried the available methods already, but it didn't work. On removing WiFi adaptor the WiFi option disappears from menu, so I am assuming the system is detecting the WiFi adaptor but showing no network to connect.

Wifi adaptor:

No wifi option on removing adaptor:

After adding wifi adaptor to the usb port:

Output of lsusb :

  • Can you give us the name of the Wi-Fi adaptor? And can you add the output of lsusb(you'll need to write this into a terminal. you can open a terminal from the applications menu). And if you can spot which one is the Wi-Fi adaptor, can you add the output of "lsusb -D /dev/bus/usb/XXX/YYY" where XXX is the Bus number, and YYY is the device number written on the same line with the Wi-Fi adapter. If you can't find it just add the output of lsusb.

  • Thanks for your time in trying to help me . As i was not able to attach the output here so i have attached it in the question itself . Regarding the make of adaptor I was not able to find it as it only has written 802.11n on top of it and as I was not sure which one is the adaptor I attached the complete output . Hope it helps in understanding the issue .

  • It seems as your Wi-Fi adapter is Realtek Semiconductor Corp. RTL8188FTV 802.11b/g/n 1T1R 2.4G WLAN Adapter, so the necessary numbers would be 001 and 002. So the second command would be lsusb -D /dev/bus/usb/001/002. I assume that you have the Wi-Fi adapter still on the same USB port on your computer, if you plugged your Wi-Fi adapter on an other USB port you'll need to adjust the numbers accordingly.

So your Wi-Fi adapter need an additional driver.

In order to install the driver you'll need to enter these commands sequentially on a terminal. As these command require sudo privileges, you'll need to enter your user's password when asked. (For security, no characters will be shown when entering a password. After you've typed your password, press Enter and the command will do it's job.)

    I still have submitted the output which is accessible by here -paste.ubuntu.com/p/t4hV3ZFRkd . So , the steps that i followed after running above three commands are as : After downloading those drivers i opened the folder and opened readme file and found out these drivers have some issue with kernel 5.15 ( my current kernel) . So , i followed the instructions given the file and at the end when I checked for one last time I found my issue was solved . Hats off to the hard working and dedicated members for helping us selflessly .

  • Will the solution work if my wifi-adapter is different, say, rtl810xe?
