How to fix Wi-Fi issues on Ubuntu 20.04 (Not connecting, No Wi-Fi adapter found)

Thank you soooooo much...the first method worked right away for me on ubuntu 22.04 kernel 6.5.0. I have been struggling with wifi weak signal since yesterday, it connected to my mobile hotspot with no issue but couldn't connect to the router. Thanks😄

you can use USB tethering from phone, if you do not have ethernet adaptor

Thanks alot man

When doing the command sudo mokutil --disable-validation, I get
"EFI variables are not supported on this system". I'm on 22.04

so i recently installed ubuntu 22.04, and right off the bat i didn’t even have a wifi option, no icon or anything. i was able to work past it by hooking up a mobile hotspot via usb to my computer, but after about a week of having that it all of a sudden stopped reading the internet from the hotspot. it would recognize the phone being plugged in, but wouldn’t connect to the hotspot. bluetooth has never worked either, so i have no way of updating anything on my laptop. i’ve yet to try connecting my wifi box to my laptop via ethernet cable, but i’m going to try and do this soon. is there any explanation for these issues? i haven’t tried following the steps of your video yet due to not having an ethernet cable yet, but i will once i get one, i was just wondering if there’s any explanation for this?

will rebooting erase my all data?

Thank you very much man. It had Worked for Me. Always while installing drivers , we must ensure that Secure Boot option is not activated. If it is activated , we will not be able to see any third party WiFi or any other bluetooth network ; "sudo mokutil --disable-validation" was the game changer. After that Reboot your system. Your system will be able to scan third party WiFi or any other bluetooth connections

i have TP-Link usb wifi adapter , after installing the drivers i can see the networks but it would not connect! still searching around

If I had wired internet I could fix this problem myself.

I'm even turning on post notification

Duuuuuuuuuuudddeeeeeee i am soooo happy 😅😅😅😅thanks mate

Thanks. Method 2 worked for 22.04 lts. Saved me. Many thanks.

It's stuff like this that are driving me insane about Linux. The most basic of problems require the most obscure solutions that take ages to find. Thanks 👍

Thanks a lot, this was so helpful!

Thanks a Lot, I didn't expect it to work after many other tricks failed but this one is a gem, it worked.

Thank you so much, you've earned a sub

Tried this but all I see is "No Additional Drivers available "

Thanks bro, your video is very helpful.

Thank you!

Not working for me :-( Installed Ubuntu 22.04 on one laptop, and upgraded from 18.04 to 20.04 on another (both are Dell XPS). On both laptops it recognizes the wifi signal, but then just sits there trying to connect. Wifi worked without problems before (with older Ubuntu versions), and still works fine on my phone. Nothing I have tried so far solves the problem. Your solution not either, unfortunately...

It worked for me by disabling the secure boot. Thank you.

I just relocated to another country, my wifi was fine, now it doesn't show. I followed the instructions. Now my Dell laptop boots in insecure mode but the wi fi still doesn't show any suggestions would be appreciated. Thanks

thans dude its the only solution

This hasn't solved a thing for me, it made icons on the screen wider..that's it. Please help, I'm unable to access the internet.

If you have a laptop you can connect an Ethernet into your laptop and connect the other end into your pc!!!! Easiest and cheapest way to do this

synaptic package manager worked.... thanks man

When attempting to disable secure boot, it tells me "EFI variables are not supported on this system." how do i fix this?

Hi, this did not work for me

It didn't work. What can I do?

Bro, you just saved me. I did the synaptic thing and also disabled secure boot and my WIFI is working perfectly now; you are a genius. Greetings from Germany.

You are a life saver man

Bro my wifi button wasn't even showing up but ur last fix solved my problem

yeah my didnt work and i tried all of the things in this video

I have (rtl8188eus) 802.11n wifi adapter it doesn't work with any linux os.

When running the mokutil command I'm getting "EFI variables are not supported on this system". Any idea what is going on? I just upgraded to 20.04.4 and wifi was working before. My computer is able to see the wifi but unable to connect, it tries and times out.

My card is the Qualcomm Atheros AR9485 with an ath9k driver.

Your videos have helped me with the same problem years ago, thank you for the content!

Thank you so much! I thought I had to buy a new WiFi card for my laptop. Your fix worked perfectly on Ubuntu 22.04.

Thank you very much!! Installing synaptic and the rtl88xx drivers and disabling secure boot fixed my problems!
I was having several disconnection issues and really poor signal on my wifi but this helped me fix it. I really appreciate it

Fucking hate ubuntu i just got a new pc and it has ubuntu

You are great

I had some issues with wifi when installed ubuntu 21.04 first time. But then after some actions i got it and it was ok. But today i started my pc and apparently wifi just disappeared. And pc was in "plane mod" or something. I turned it off but wifi didnt appear. I tried all the solutions from your video but still no wifi

You're a life saver, thanks for the video and explanation 👍

I have two wifi-adapters that suddenly disappeared from Ubuntu 20.04, and the reason was this: I have a dual boot setup with Windows, and I had to disable the internal wifi card on my main board (intel) to make sure Ubuntu was recognizing the USB-wifi. Crazy, but worked for me.

As a noob, your speed running of this makes it difficult to follow, bro slow down.

you are a G E N I U S....once again G E N I U S .... Thank you man! The really one method that really works.

Thanks, really...Thanks!!!!!!!!

bro thank you!!!! after hours of trying to get my alfa adapter to work on a fresh ubuntu install it finally is recognised!!!
would recognise lsusb and i have installed the drivers several times wiith dkms still nothing... then finally tried this solution and hey presto!!!!

absolute legend, subscribed to your channel !!!

Dude. Awesome. I was freaking out. Those trying to find out your WiFi card info 》open terminal 》type sudo lshw -C network

Great..2nd one worked for me thanks!
