Frequent 90k + 90002k error

Hi SE, I've played for a while and then took a break and returned.
However every ten or fifteen minutes of playing i, without lag or any other warning get a black screen and a 90k or 90002 error.

Server: Balmung
IRL Location: New Zealand
Internet Provider: Orcon

I have:
- reset my router
- re installed FFXIV
- Ran as administrator
-updated all my drivers
- brought a new network cable
- port forwarded to the server and FFXIV
- danced to/for the internet gods
- used programs like 'pingzapper' etc
- swapped characters, problem persists on all toons.
- Ran a ping test: no loss at all.
- turned off my clock sync


Anything else I can do?

I get the 90k errors on Phoenix as well, coupled with extreme bouts of lag. Hope the maintenance tomorrow morning fixes it.

I have had the same error for a week now. I contacted Square Enix support, they pretty much told me you have to be hard wired into your router or don't bother playing.

I still have this problem and I am hardwired to my router.
