Recent zone loading freezes, crashes, & failure to connect to server

[Obeast44]

I am having the same issue on my home connection. Everything else works perfectly, youtube, Netflix, Kodi. As soon as I try and login to P99. I have no servers showing. If I do manage to get in after 20 tries I cannot zone or it will crash. The very second I disable my home network and enable a wireless 4g tether, everything immediately works perfectly. I have noticed this really only happens on the weekends or during peek hours. Is there something I can do to solve this?
