The first thing I see is that your wireless card is connecting to a completely different network (router) than your wired connection.   The wireless is connecting to an attbi connection, while your ethernet is attempting to connect to comcast.  Which of these is your internet provider (I would assume that it is attbi).   Are you connecting by wireless to a neighbor's wireless network?  Have you reset your cable modem when you changed the connection from a computer to a router (shut everything off, wait a few minutes, turn on the modem first, wait a few minutes more, then turn on the router and then all computers)?  If this isn't the problem you need to explain how everything is connected together in your network.

connecting automatically through a neighbor's wireless network until we can get this figured out - no wireless router yet. Comcast is the isp and was working fine up until a few days ago.

Yes, we have worked through the power cycle - disconnected everything and reconnected after about 10 minutes from the modem up through the computer - to no avail.

Thanks.

I'm writing from another computer. We have disconnected the laptop from the cable modem, disabled the wireless connection, shut everything down and unplugged. We then reconnected the cable to the modem and turned on the power. Waited 15 minutes, then connected the cable from the comcast modem to the laptop and then turned it on. Still no internet connection. I also tried this same routine but turned the laptop on first and then connected the cable from the modem to the laptop - no go. Any other things we might try? Thanks.
