This evening I've been having a hell of a time with my wireless connection. I have an aging Microsoft G router, which is located in our living room. I haven't been able to stay connected to it tonight for more than a couple of minutes at a time. My work laptop can find the wireless network but not connect to it (even though it was able to earlier today). I think my 360 has even been having trouble with it.
When I move closer to the router, I can stay connected for longer. When I am connected, signal strength always shows as "excellent," but speed is up and down.
Is loss of signal strength a common symptom of a dying wireless router?
