No Wifi in Linux Mint After it Had Been Working - Why? How Can I Fix It?

[Victor92]

Hi,
My Wifi stopped working but it had previously been working just fine. I've been using Linux Mint for over a week with no Wifi issues so I don't understand why this would happen now. I reinstall the linux work's fine and today the same, i don't have wifi. I see the problem in another topic, i tried the solution from there, but nothing, by the way i am new on linux.

Thank you,

CPU Topology: Quad Core model: AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx
Kernel: 5.4.0-70-generic x86_64 bits: 64 compiler: gcc v: 9.3.0

Numerous subsystems can underperform or falter when the kernel doesn't speak new Ryzen. The solution is kernel 5.8, which has recent AMD-specific enhancements and bug fixes. It's more than just the Ryzen APU, there's an accompanying suite of AMD I/O chipsets. Kernel 5.8 immediately resolved several issues on my Ryzen 7 laptop.


Kernel upgrade: Launch Update Manager, there click View > Linux Kernels > [Continue]. Then select 5.8 and install the top version listed. Reboot.


Once your AMD chipset is happy, remaining issues can be easier to pinpoint and resolve.

Was strange, now when i move on linux, the wifi working without do nothing, but i upgraded the kernel to 5.8 and i hope i will don't have problems again with the wifi. Thank you guys for the help.

So, the wifi worked before you upgraded to the 5.8 kernel?
