i have been experiencing the same problem as you and this started about a week ago.
last night i was able to get 3 hours of play after adjusting my internet settings aswell and now im back to square one as im disconnected every time i log into my character
i dont know what to do and this si starting to get on my nerves aswell but my friends in the game isnt experiencing the same problem as we are.
ive tried other games and they are doing what ffxiv is doing and thats resetting my internet connection all together now.
i have contacted support and they say there isnt any issues popping up with there servers but i dont know now
i hope the GMs or someone sees this post so they can understand whats happening but ill contact them again
