Connection issues after a kernel update.

Post by dalinar » Wed Nov 14, 2018 11:59 pm


I love Linux Mint and would love to keep using it for as long as I can. I have a problem, though. After updating my kernel from 4.10.0-38 to 4.15.0-39. Before updating I can connect to the wifi in my apartment and on campus at my University. After updating, I can still connect to the wifi on campus, but I can't connect the wifi in my apartment. So, I rolled back to the first kernel and posted this. Can anyone help me with this?

The output of iwconfig is:

I have already tested for soft and hard blocks and that's not the case.
I would really appreciate help on this.
