Thanks for the tip. It does sound a bit like Russian to me but I'll try to look in my router and see what I can figure out. Quite frustrating, to run into a semi-known problem that is not large scale enough for Capcom to really take notice.
If everything works as normal except for an in-game update, surely the fault lies not with my router setup but Capcom I'd argue, but then again, if they don't seem to be aware then what can I do except try to solve it myself? Sigh...luckily I'm not someone trying to train for Evo who would now suddenly be without online practice capabilities or the latest fixes...
