No WiFi after Linux 20 install
Hello,
I am a long time reader, but a novice Linux user. I had Windows 10 on my computer before installing Linux Mint 20 where Windows was deleted. Although the WiFi worked without any problems before the install, it disappeared afterward.
Now, the only network device listed is a Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet. I purchased a WiFi bridge to try to connect just long enough to do the required updates, hoping they would fix the WiFi issue, but I still cannot get online. When I first plugged in the bridge the computer said it was connected via Ethernet, but it still would not open a webpage. I restarted the computer and now it won’t even connect to the Ethernet.
At this point I am not giving up, but have no idea what else to do.
Thank you in advance for any advice you can share!

Re: No WiFi after Linux 20 install
@NordicMonkey - the first character in that command is the letter l, not the number 1.
If you have found the solution to your initial post, please open your original post, click on the pencil, and add (Solved) to the Subject, it helps other users looking for help, and keeps the forum clean.
Re: No WiFi after Linux 20 install
Copy & paste that command rather than typing it to avoid typos.

Re: No WiFi after Linux 20 install
I would prefer to paste the text, but can't as I am using another computer's internet while I work on the one in question. The above code did work once I changed the "1" to an "l" -- thank you @Lary78723 for the clarification. Below is the result:

Re: No WiFi after Linux 20 install
Is your ethernet cable plugged in? If so, unplug it, that can block wifi.

Re: No WiFi after Linux 20 install
It is a wifi to ethernet bridge. Should I run the code after unplugging it?

Still nothing. Thank you for your help.
Re: No WiFi after Linux 20 install
Ok, I'm not familiar with a wifi to ethernet bridge issue, so someone else may know.

Re: No WiFi after Linux 20 install
I am open to try any fix for this. Before the Linux install, Windows connected to the WiFi without any problems. The WiFi to Ethernet bridge was purchased only to try and fix the original issue of Linux not recognizing the WiFi. It is not a necessary component.
