I've got a Belkin Wi-Fi router, it seems to be getting weak. The old one can't seem to go through 4 walls and about 30 feet. I'm a computer noob. I logged into the URL,or IP address, whatever it's called, of the router and its been set for upgrades automatically on the software for 5 years, but hasn't seem to have done it. Should I get a new Wi-Fi router? I'm thinking yes. A friend suggested a Netgear router. My kid set the old one up Are they plug and play? $100-$200 for a router or so, I don't care. Thoughts?
