[SOLVED] Linux Mint 18.3. Wi-Fi doesn't work.

Post by viktor1405 » Sun May 20, 2018 6:29 pm

Hey, Guys!

I've installed Linux Mint 18.3 alongside Win10 on my Lapop. The Network Manager sees all the Wi-Fi networks but after an attempt to connect, it thinks some time and gives no result. It even doesn't ask for login and password.

Interestingly, when I share mobile internet on my smartphone, I connect to it easily. From the other side, the network I need works for Win10, smartphone and tab but not for Linux.

Here is the results of

Code: Select all

inxi -Fxz
if it's relevant.

I've noticed in many topics people face the similar problems but the solutions either weren't helpful or I'm not proficient in Linux enough to understand them. Please, explain me what may be the problem.

Please try installing highest kernel version 4.15.x and 4.4.x. After each install reboot and test. Good luck

If I follow you, I should go to Update Manager -> View -> Linux Kernels and find them there.

If so, I installed 4.15.0-22 and 4.4.0-127 and it doesn't help.

Please see the wireless script link in my signature and post results. I have that same wifi card and it works fine. Also post the manufacturer and model number for the computer

sudo iwconfig wlo1 txpower 18
Then see if it will connect

And it seems like the field Tx-Power is reset to 0 again after reboot.

I wonder if

sudo iwconfig wlo1 txpower auto
Might work better

This solved my wireless network issues on 17.3

Code: Select all

sudo apt-get install linux-firmware-nonfree
sudo apt-get install linux-headers-generic
sudo apt-get install bcmwl-kernel-source
sudo modprobe -r b43 ssb wl
sudo modprobe wl
That solution came from here: https://askubuntu.com/questions/234047/ ... rd-working

You might need to do some more googling, since this answer is for Broadcom adapters but I see you have a Qualcom adapter

I just found that people have unstable connection with this network chip. I can't connect to a certain network at all.

I am still not sure that the problem is related to chip or drivers because for example I can connect to my smartphone's hotspot and everything works.

But when I try to connect to the exact network it loads a while and results in no response

Works, out of the box, in Linux. windows can use with drivers installed.

I would actually install and use a 4.4 kernel unless there is an issue with your video card with 4.4

From what I can see, the biggest issue is something keeps setting the tx-power to 0 and I haven't seen any kernel do that to my AR9485 wifi card

I guess we could set the country code

Code: Select all

sudo iw reg set DE

It's a pity that I live in student dorm and I'm not allowed to change anything in network infrastructure here.

Region setting doesn't help

I have 4.4 installed. But it's denoted that 4.15 is active. How can I change it?

Finally, I found the solution. It turned out to be extremely simple.

Despite the fact that the network I need was in the list of available neworks, I should have press button "Connect to Hidden Network" in network manager and type in the appropriate settings. In my case it looks as follows:

Connection: New
Network name: networkname
Wi-Fi security: WPA & WPA2 Enterprise
Authentication: PEAP
Username: username
Password: ********
