v2.1.2 Wifi Issues

So I can get wifi connected with the 2.1.2 image over psu but it doesn't last. For me when it stops working the entire system stops working and requires a hard reset but cutting power. Sudo reboot now and shutdown now just send it into an endless splashscreen. I have not been able to determine how long wifi stays connected but it's less than 10 minutes. In my picture below I took it as soon as ssh became unresponsive so in that case it was 3 minutes.

No source files, tests, or entry points are named. Start by reproducing the issue with the v2.1.2 image, observing the WiFi and SSH failure, and checking whether reboot or shutdown reaches completion. Done means identifying the cause of the system lockup and confirming that WiFi remains connected and the system can shut down cleanly.
