Unifi Controller Change - Nothing but Issues (Dropouts, Uploading, Connection Loss)

What is the problem?

OctoPi loses connection during printing. After starting a print I cannot pause or cancel a print. When attempting to do so the conneciton times out and printer goes on printing.

My system worked without issues but since upgrading my Network controller to a Unifi Cloud Gateway it's been nothing but issues with my OctoPi. I'm convinced this is related to a setting on my Unifi system but I'm not sure which.

Other Issues Related to the Above:

  1. Cannot upload files from a Windows PC, I can access the UI via static IP from my PC and control the printer (temp, home, etc) but when I upload a file it doesn't upload. The upload bar starts but than the bar freezes. I can however upload files from my iPhone without issues

What did you already try to solve it?

Fresh install of OctoPi
Static IP
Disabled Power Save Mode via SSH

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog... no bundle, no support, unless the reason you couldn't retrieve the bundle is your network issues
