ok so everyone knows i am not too computer savy, today i logged onto tf2 and was going to join a server and it tried to connect me, i waited about a minute, and it said connection failed after 4 retries. I closed steam and reopened first of all, but the problem persisted, so then i went to a full reboot of my computer, and the problem was still there. Finally i rebooted my internet connection tower, and even that didnt work. Does anyone know what might be wrong, and what i can do to fix it?
