I read it twice and let's say it's not the router. So what has been done about the internet source?
I'm at home and everything in my house will occasionally drop connection, as in I'm playing a game on the computer, it looks like all of the players have stopped moving, then they end up in a completely different spot (when the connection comes back). If I'm on Skype while this happens, the voices of the people I'm talking to will stop, and they won't be able to hear me until my internet decides to come back again, which usually takes about 5 seconds. This problem has been going on for about a year, happens on all devices in the house (even wired) and has not changed through all the routers we've been through. So no, it's not a router issue. Modem? Maybe. I never have to reset the modem and router because of it.
Also, since I know a lot of you are going to say change the wireless channel, let me repeat myself: THIS PROBLEM HAPPENS ON BOTH WIRED AND WIRELESS DEVICES!!!
Any help would be greatly appreciated.
