This is very frustrating because i'm trying to play some games with my friends but I can't connect to the internet. I can get online on my browser but I can't get online with some of my games. I can't connect to gameranger client or this other game client called voobly. I can't connect to online for some games on steam like call of duty world at war but I can connect to other games like counter strike. I also can't connect to minecraft online unless it's port forwarded. I can connect to anything though when I use a different internet connection, I usually am connected directly to my modem and when I use this connection all of this occurs, but when I use my wireless router none of this occurs but it has a much poorer signal. Ideally I wouldn't want to have to use the wireless router so please help me sort this out because it's very confusing and is making me angry.
Added (1). I just tried to do a ping test with the modem and then wireless router. With the modem connection it fails and says Packet Loss Test Error
Couldn't connect to the test server. A firewall could be blocking the connection or the server might be having some issues. Please try again later.
But with the wireless router connection it succeeds.
