I am not so new to Ubuntu, familiar since 16.04 now recently upgraded to 18.04 and my WiFi is not working properly ever since,I freshly installed 18.04 but still facing the issue so figured as always read some blogs and see some videos to fix that but no use. I a using hp pavilion g6 2314ax. Please help me. Thanks in advance. output of 'lshw -C network'.

Please note the error:

rt2800_probe_rt: Error - Invalid RT chipset 

A search for the error returns this: https://ubuntuforums.org/showthread.php?t=2257359

Ok so it didn't work on win7 either so I plugged it out and cleaned everything with vacuum cleaned, and it just worked!

And this: https://lists.opensuse.org/opensuse-bugs/2015-11/msg03170.html

The problem appears likely either a BIOS or a hardware problem, so I would check BIOS setup (reset, or complete clear by removing CMOS battery) and proofing the WiFi adapter connection.

In this context, I believe that “...proofing the WiFi adapter connection” means to make sure that the contacts are clean and the card is securely seated in the PCI slot. Basically, that means exactly the same as the above post.

In short, I believe it is a hardware issue and not a driver or operating system issue.
