I have a cable modem connected directly into a time capsule, nothing fancy at all. Lately i've been losing internet access and I can't seem to figure out where the problem is. I'm connected to my time capsule wirelessly with good signal strength and the green light on the TC is on, but I can't hit any web pages from any computer or devices via wifi. I cycle power to the modem and TC at the same time (they're plugged into the same strip) and it works again for a while. The lights on the modem all look normal to me. How can I tell if it's my modem or TC that is causing the problem? Any help is appreciated.
