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!
