Disconnects every 2 hours, error 90002

[OdoriTsuki]

Things I have tried:
-Reinstalling the game
-Switching to wireless connection (am wired)
-Port forwarding all the recommend ports from previous threads concerning the same error issue
-Disabling scanning of ports on my router's setting
- Going back to an older firmware setting my router as well as newer
-Clearing Internet Explorer's cache and lowering all security settings to its minimum
-Keeping multiple game's open and connected, seeing if they would disconnect as well (Only disconnect from XIV)
-Changing my wired connected port on my router
-Conducting ping and packet loss tests to see if I am losing packets
The only thing that has worked for me is connecting to the game through my phone's 4g connection. That needless to say I can't do constantly with limited data as well as it being a poor connection compared to my mainline connection which is 100 down and 20 up.
Edit: I forgot to mention that I have a roomate that has the same issue. This has been a problem since patch 4.4, we are both on Primal Datacenter on Ultros.
