I have same problems. Recently having trouble connecting, so updated to 4.16. My ISP is TalkTalk, and getting no bars at all in the connections box. I also have a Linksys 354G wireless router, and this is fine. Also tried to manually port forward, but no luck. The Router firewall is turned off, and I only use the XP firewall. Suspect that it is ISP troubles, although have tried emule to check, and it is very slow, but connects OK.
