Drivers for this chipset should be in the latest kernel

run in terminal inxi -F
scroll down to network copy and past that section

If I remember right Ubuntu 20.4 LTS does not come with inxi installed. op will have to install it first.
sudo apt install inxi then run the command.

Search for the following firmware - rtl8822befw.bin - it is usually located - /lib/firmware/rtlwifi - to see if it is installed or not
Also run
Code:
lspci -nnk | grep -A2 0280
and post back the output

well you have the correct wireless drivers installed,

the problem is with the pci driver

found this from 6 months ago

I don't think so cuz I tried an external interface today and it didn't work

is it possible that the driver is being hard blocked?
not common but again a possibility, some of the Realtek chipsets are a right pain in the backside, so I start with the most common cause

Brickwizard is right Realtek can be a real pain to get going.
A couple things that may be of help Make sure secure boot is turned off. It can block some wifi drivers.
on most Lenovo's the hardblock means there is a combination of F keys that need to be pushed to turn the card on. On my thinkpad it is the Fn F8 combination. But yours may differ.
the drivers with debain may not be the correct ones for your card and you may need to check on github to find a newer one. Also on some machines bluetooth and wifi will not work at the same time.

Can you try USB tethering and verify whether internet works or not ??

I had faced such problem before and there is no solutions to that except reinstalling the OS (At least in my case i was running Ubuntu 20.04, 21.04 & 21.10 and couldn't able to find proper solution to No Internet issue)

If you choose to reinstall as suggested by Sunil1991 download the non-free version it will have the drivers you need.

You could check your resolv.conf file to see if there is a nameserver listed
Code:
sudo gedit /etc/resolv.conf
It seems to me that it is not picking up the nameservers in the connections dialog boxes - by default Ubuntu uses 127.0.0.53 you may have to add
Code:
nameserver 8.8.8.8
to the resolv.conf and see if it starts working - add it just underneath the 127.0.0.53 - note this is temporary and will rewrite back to the original after reboot- but if it works I can tell you how to make it permanent

Glad to see you got it going. You might want to explain further so others with the same setup can benefit.
