Internet / bluetooth issues after motherboard replacement

I had an issue with my Precision 5550 randomly shutting off and then not detecting the power adapter on restart. 

It was finally fixed three days ago with a motherboard replacement. Unfortunately I am now having problems with my internet (both wifi and ethernet) as well as bluetooth.

Wifi and ethernet work sometimes. I am unable to connect to my office wifi, which uses WPA Enterprise. My network manager keeps just asking me to provide my password as though it is simply WPA. Bluetooth scans endlessly and never finds any devices. I have the problem on Ubuntu 22.04. When I boot into Ubuntu 18.04 with a bootable USB, I have the exact same symptoms. 

So far I have updated the BIOS and reset the BIOS default settings, with no luck.
