forever DCing

I DC every few mins (in dungeons and flight paths ALL the time, i haven't completed a dungeon without a dc for weeks), its beyond a joke now. ive tried the usual no add ons etc etc still DC..... (i do donate fairly regularly a fiver ere n there so not sure its that) i have another pc in the house that my brother plays this on too and he never DCs, when i play on that pc i DC so is it my account in some way ??? ive uninstalled and reinstalled the other day but still the same ...
made a ticket but got a "nothing they can do" answer

this is really winding me up and I'm about to quit as its unplayable for me...

any ideas or advice would be great or ill be uninstalling lol. thx

guess I'm uninstalling then. not wasting more time on this garbage..

Hey so there is a known issue that causes DCs if you downloaded the "new" wotlk client. You may not even be aware that it happened, there is a certian file you need to delete in your wow folder. remove Patch-W.mpq in Data folder, as well as patch-enUS-w.mpq in Data/enUS folder

This is one possible solution. And I'm sorry to hear about it
