This has been going on for a long while now. While the internet on my computer is fine, for everyone else it just goes off at times and I always have to unplug/replug the router to make it work again for them. I tried getting a new Linksys router to replace the old one, but it wouldn't connect to the internet unless it hooks up to the old Linksys router that I'm trying to replace like an add-on. I've tried what seems like everything and it's either only I get constant internet or no one gets it. Now even my Xbox360 and PS3 are suddenly disconnecting as well.
I've checked the modem and it shows that I still get internet so it has to be the routers. My internet provider is Comcast.
I'm at my wit's end on this and could use some help.
