My wireless model is:

According to the label: BCM943142Y

According to lspci: BCM43142 (rev 01)

My network adapter's ID is: 14e4:4365 (rev 01)

bcmwl-kernel-source is installed, and the Ubuntu software thing says that my WiFi device wlo1 is using it. This is the correct driver.

Connecting to my phone hotspot works fine, so I am able to access the internet with it. I only get so much data though, and it's very slow. It fails to connect to all other networks here at my university and in my dorm. Looking through syslog, it gives up connecting when it times out, saying that it failed to get IP configuration. I had windows before, and the WiFi worked flawlessly.

I'm not even sure if this is the right log, or the right part of the log, but here is something in /var/log/syslog that looks relevent:

  • @AndroidDev What should I do if this doesn't get answered? I feel like I'm close, I'm feel like it's the configuration of the dorm's network that is causing the issue, I just don't know how to configure my end. Or it's a different problem entirely, I don't know. I was able to get WICD to work on this network sometimes before I reinstalled ubuntu 16.04, but usually it did the same thing that's happening now.
