I have a linksys router with similar problems.
Firstly with Ts1 it used to connect fine but I could not be able to hear new people to join chats and after a while I would loose my connection or I would have trouble changing rooms although after about 30 seconds to a minute of nothing appearing to happen it would change room and I would suddenly be able to hear new users.
After a while the problem suddenly stopped. I think this was due to me changing port settings on the router to fix a couple of problems that I had with msn (the msn problem turned out to be a faulty router)
Then I installed TS2 initially I had no problems except for the minimise/maximise/close bug
The other day my replacement router arrived and once again my TS1 problems returned with some new problems for TS2 (not fully tested it yet) I can no longer access the site though its domain name or the IP that is directly linked to the domain. Instead I have to go though the server list and find it on there. The ip that comes up on the server list is the one of the virtual host where my server is based. I tested to see if the problem stopped if I removed my router and it did.
Tomorrow I may try calling the linksys helpdesk as I think it is some kind of port problem.
Some of my clan mates have a similar problem which can be seen on our forum at
