I bought a WRT54G v3.1 (European model) recently and I hooked it up. It seems to work fine apart from one (well two but I haven't tried anything about the other) problem, I can't seem to maintain a stable connection to World of Warcraft. When I log on all characters appear as Unknown, I can't seem to speak and about a minute later I get disconnected. When I log back in I'm in the same place I logged on in the last time. I've only managed to get a few periods of stable connection, after that it just goes back to how it was before. I believe I've forwarded the correct ports so I'm not sure what else to do.
