I have an SB6141 connected to an Apple Airport Time Capsule. Lost wireless internet access a few days ago. Ethernet connection to laptop works fine. Ethernet connection to wireless router, doesn't. Airport says the ethernet cable is not connected, but it is. Thought it might be a modem problem, installed a new SB6141, (I've been having to reboot it frequently lately, as my internet speeds have been bottoming out) but it still didn't connect with the Airport. Installed a new Airport router, and still the same problem. No wi-fi. Says the ethernet cable is not connected. And I've tried several cables, two of the brand new. So, with brand new equipment giving me the same error messages, I have to wonder if its something on TWC end that's changed?
