NETWORK IS BEAKING THE OS

[Erick Luiz Bertolini]

Hello, my Uuntu 20.04 has a problem, I've formatted it countless times and this error always occurs.

I'm doing something, the system simply informs that there is no internet, and it really runs out of internet and if I try to connect in my hand, it simply locks the entire system, leaving the fan running.

I use Ubuntu, as my computer is a Macbook pro 2012 and will no longer receive a system update.

Macbook pro 13" i7 mid 2012 original network card.

From what I noticed, it looks like a loop is occurring, but I couldn't get any more details due to the crash.

We can keep this bug about your networking (wifi?) problems.

Although looking at your kernel log there appears to be a separate issue: Your 'SanDisk SSD PLUS 120GB' is experiencing hardware faults which may indeed break the OS. That problem is not related to networking. I suggest you try replacing the 'SanDisk SSD PLUS 120GB' or just unplug it if you don't need it. Hopefully the problem is just that drive and not the motherboard. But again, your disk problem is separate and unrelated to wifi problems.
