One problem I see is your router. The Linksys WRTG has buggy firmware and they never repaired it properly. ie: UPnP mode does not work reliably. (UPnP mode is where a program sends a request to the router to open ports for it.) The best answer to the wrtg is port forwarding. (There is a 3rd party firmware fix for the Linksys wrtg however it's not recommended for beginners.)
Have you tried resetting your router? |
