I have Ubuntu 20.04 LTS installed alongside Windows 10 on Lenovo Flex laptop. The wifi works fine on Windows but when i switched to Ubuntu the wifi is not showing. I have tried many of the instructions on how to fix it but still the problem is not solved.

The output I get from lspci shows Realtek RTL8822BE wifi adapter present.

I really need my ubuntu wifi back, I have trying for 2 days to fix this problem. Thank you for the help!

  • What were you trying these ttwo days? Why don't you search for soulutions for rtl8822be? – Pilot6 May 20 at 21:06
  • Please edit your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. – Pilot6 May 20 at 21:08

  • In Ubutnu 20.04, your device is driven by the built-in driver combination rtw88 and rtwpci. Let's load it and check the log for informative clues: sudo modprobe rtwpci && dmesg | grep rtw Next, edit your question to add the result. – chili555 May 20 at 21:38
