Internet disconnects happen, but this is different.

When ever I get disconnected from ff14, and ONLY from ff14, my computers entire connection to the internet goes down.

Router still works, Modem is still connected, other computers in the house can access the internet, but my computer has to be completely shut down and rebooted (just using restart doesn't work), in order to get reconnected to the internet.

Like I said, it only happens with this game, any other game or program, I'm able to jump right back in or access web pages, but ff14 forces a complete shut down.
