No wifi adaptor found Ubuntu 18.04

[jeremy31]

I know they are different wifi devices, they are even different ubuntu versions, just suggested it could be the kernel because the error it showed to me was pretty similar, especially about not been able to create wireless connections, sometimes a single solution could help a lot of people...

I have yet to see an error posted by mrboler that would suggest the issue is similar to yours. mrboler is still using the 4.15.0-23 kernel from the wifi script results and the driver is part of the kernel
The perplexing thing is that is says, Kernel modules: rt2800pci rather than Kernel Driver in use rt2800pci

[mrboler]

I needed Ubuntu for the project I developed at work, first I installed ubuntu on my own computer and brought the project to the end point. After a week I have to make a presentation for the project, but the system has to be working on the company network. I met this problem on the business computer.


Tomorrow, Sunday, I will go all day to deal with this problem. I will try your last advices. I hope I can reach the solution... If I can not solve the problem, I might need someone to help me connect to my computer and help out.

Have a good night.

Hi guys,

I don't know if this still works with newer kernels

sudo apt-get install --reinstall linux-headers-$(uname -r) build-essential dkms
wget http://media.cdn.ubuntu-de.org/forum/attachments/34/30/3473742-Ralink_5390sta-2.5.0.3_dkms.tar.gz
sudo tar xvf 3473742-Ralink_5390sta-2.5.0.3_dkms.tar.gz -C /usr/src
sudo dkms add -m Ralink_5390sta -v 2.5.0.3
sudo dkms build -m Ralink_5390sta -v 2.5.0.3
sudo dkms install -m Ralink_5390sta -v 2.5.0.3 
wget media.cdn.ubuntu-de.org/forum/attachments/08/18/3473742-RT2860STA.dat.tar.gz
sudo mkdir -p /etc/Wireless/RT2860STA
sudo tar xvf 3473742-RT2860STA.dat.tar.gz -C /etc/Wireless/RT2860STA 
echo "blacklist rt2800pci" | sudo tee -a /etc/modprobe.d/blacklist-rt2800pci.conf

Reboot. If its not working, revert it

sudo dkms remove -m Ralink_5390sta -v 2.5.0.3 --all
sudo rm -r /var/lib/dkms/Ralink_5390sta/2.5.0.3 
sudo rm /etc/modprobe.d/blacklist-rt2800pci.conf
sudo modprobe -v rt2800pci

sudo dkms build -m Ralink_5390sta -v 2.5.0.3 : Output:

still no wifi adaptor found...

Anything for

dmesg | grep rt2

[mrboler]

Hi,
Thank you but nothing happened.

[praseodym]

Please check

dpkg -l linux-* | grep ii

[mrboler]

I reinstalled Ubuntu 18.04 again. I only do update-upgrade and update to kernel 4.16.17. I'll never try another internet solution . I am waiting for your advices.

So when I tried again with a clean OS.

I am not sure what that invalid RF chipset error is about, you should file a bug report @ bugs.launchpad.com/ubuntu against package linux and at the kernel.org bug system
