Wifi problems with Ubuntu 20.04 Focal Fossa

Solution 1
Here's a solution I found on another forum. Looks like it has worked for some others quite well. I have not tried it myself since I don't have the same issue.
Change directory:
cd /lib/firmware
Make Directory rtw88
sudo mkdir rtw88
Copy rtl8822befw.bin to the directory you just created:
sudo cp /lib/firmware/rtlwifi/rtl8822befw.bin /lib/firmware/rtw88/
Rename that file to rtw8822b_fw.bin:
sudo mv /lib/firmware/rtw88/rtl8822befw.bin /lib/firmware/rtw88/rtw8822b_fw.bin
reboot your system
Solution 2
I've been having this problem of the network dropping, with a "?" in the network icon, in the top right corner.
The following worked for me, without having to reboot the PC.
sudo nmcli networking off
and then,
sudo nmcli networking on
Solution 3
It seems to be a kernel problem. When booting you can select Ubuntu Advanced Options from the GRUB menu and select the kernel which works for you (i choose generic kernel).
You can download and install the generic kernel form the UBUNTU kernels which i downloaded generic kernel following the steps provided in the link (https://www.tecmint.com/upgrade-kernel-in-ubuntu/) solved the problem.
Note: I have installed generic kernel version V5.4.81 from https://kernel.ubuntu.com/~kernel-ppa/mainline/ seemed to work fine for me or you can choose the kernel you like.
Solution 4
Just had this problem after upgrading kernel to 5.4.0-54-generic on my lenovo laptop.
The solution was to reboot twice
I performed the upgrade using sudo apt upgrade and then rebooted, then selected continue booting at boot menu.
Upon reboot I had no wifi. The interface was missing. I rebooted again and everything was fine.
Solution 5
flow this steps to config:
0 config sys location
sudo tzselect
sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
date -R
1 install network tools
sudo apt-get install net-tools
2 start wifi
sudo ifconfig wlan0 up
3 edit wifi config
sudo nano /etc/netplan/50-cloud-init.yaml
4 apply config
sudo iwconfig wlan0 power off
sudo netplan --debug try
sudo netplan --debug generate
sudo netplan --debug apply

So I did a clean installation from 18.04 LTS to this new version, and I am really liking it, but I usually connect an Ethernet cable for the installation, the thing is that when I disconnected I found out that I have the same problem that I had with Pop OS some years ago, I have a laptop with the Realtek RTL8822BE WiFi card, and Bluetooth works great, but when I enable WiFi no networks show up.
I already tried
sudo service network-managerand didn't work, I have noticed that it has downloaded some sort of driver for it, as it doesn't appear in Additional Driversmaybe this helps:

Anyway I think that maybe this is a problem of the release as it's brand new and just came out today, and probably not many people have this awful card.
Thanks,

jcollum over 2 yearsI feel your pain, I'm dealing with a ton of wifi problems here too. 5 computers in my house (including phones) and only the linux machine is having wifi issues.

sanmacorz about 4 yearsWell, it didn't work lol now it doesn't let me to turn on wifi so I guess something changed, thank you anyway
-
sanmacorz about 4 yearsAlso probably it didn't work because I already had the folder it appeared
mkdir: cannot create directory ‘rtw88’: File existsso yeah I don't know why -
sc608 about 4 yearsSorry to hear that news! My research indicates a lot of problems with that wireless card and later versions of the Linux kernel. There's a Git repo that has the latest drivers for your wireless card here - (github.com/lwfinger/rtlwifi_new) Complete with step by step instuctions for installing -- if you want to give that a try.
-
sanmacorz about 4 yearsThank you so much! that fixed it I just followed the simple steps for my card in the GitHub repo and that was it, now it's working just fine.

s1mmel over 3 yearsPlease be more precise with your answer. How do you do select advanced options? Which one is the right kernel? How do you know this kernel ist already installed? How do you install this kernel and make it the default option at startup? -
Zanna over 3 yearsWhich kernel version works? -
jcollum over 2 yearsworth noting that you DO NOT want to do this if you are using ssh to connect to the device, it will kill ssh as well
