Suffering 90002 errors exclusively with a gamepad!

Hi,

So, as the title says, I'm getting TONS of 90002 errors when trying to play FFXIV with a gamepad (I'm using a logitech f710, it has Xinput support). I'll maybe get 10 minutes of consecutive gameplay before a DC? With a KB+M however, I can play indefinitely without any interruptions.

My ISP is Virgin Media, and below is my rig:
4790k @ 4.6GHz
Gefore GTX 980 Ti
16gb Ram
1500w PSU
Samsung 1TB 850 Evo SSD

Please help ;_; I wanna lay in my bed and gather ore and rocks...
