Does it happen with separate WoW folders for all the clients? What's your computer like?

Yes, all WoW's had an seperate folder when I tried it on my main.
Well my main: AMD X2 4400+ | 2gig ram | gforce 8800gtx.
System 2 (desktop): P4 3ghz | 1gig ram | x1900xtx
System 3 (notebook dell): P4 2,8ghz | 1gig ram | ati 9700 mobility
System 4 (notebook gericom): Centrino 1,4ghz or so | 512mb | 9700 mobility
All connected via cable, no WLAN!

Personally I think it's that network issue, thought it would have been fixed by now, 128 kilobyte upstream will get choked.

I think so too :/ Hope when I move to my new house with ADSL 2000/386 it's going to work, but that's gonna take 1 or 2 months
