Currently trying:

Documents\My Games\FINAL FANTASY XIV - A Realm Reborn
open FFXIV.cfg with notepad
find
<Network Settings>
set UPnP to 0

update - no change, still dc'ing every ~hour



Edit -

I am 100% positive this has to do with the packet loss associated with DHCP renewal requests.

I can replicate this every. single. time. I test it, with multiple networks. It disconnects within 3 seconds of the renewal time on each and every renewal.
