+ 0 Votes How have you determined that the router is the problem? seanferd 3 years ago Although the first thing that does come to mind, given what you have said, would be interference. If the signal is bad long enough for the connection to time out, it will. + 0 Votes I would hope seanferd 3 years ago that there would be no communication over the port/protocol at all. Then again, I've seen some weird behavior from routers, so a leaky iptables/firewall may not surprise me. UPnP (kill it!) can defeat the best manual configurations if left on, it seems. + 0 Votes Have you isolated the problem to the wifi link? TobiF 3 years ago Try connecting your computer with an ethernet cable to the same router. If it works well over cable, then we need to look into the wireless: signal strength, radio interference, wifi protocols If the problem remains even with the cable, then there may be some problem with the router, firewall, site, internet provider. + 0 Votes Port Forwarding Enforcer Drive 3 years ago It depends what protocol you are using. But some protocols are blocked on wifi routers. Find out the ports that your application are using and make sure they are forwarded in the router. For example in a dlink router you have to allow utorrent through the virtual server tab.
