Hi all, I just signed up (for my elderly mom) with Comcast for their hi-speed Internet service (performance level).
Self-install kit included the ARRIS model TG 862G/CT Wi-Fi tower modem.
Since I don't want to make matters worse than they are now, I haven't uninstalled the network card yet.
When I put the CD in the computer, and after getting the Starting installation wizard message, a software setup screen then comes up with Select components.2 boxes with check marks on them. I told her that if we don't get this darn thing resolved before Sunday night, I'll just return it to Comcast and try another one. If the modem and the computer are within reasonable proximity, connect them with an ethernet cable.
Also, make sure that you are using WPA(2) Personal (PSK) for both the Comcast gateway, and for the Wi Fi client that you are setting up; don't try to use "WPA-Enterprise" or "802.1X" security because that almost certainly will require resources that you don't have (resources such as a security certificate for that connection).
I can't provide you with a screen shot of how to do this because I don't have access to the Comcast gateway that you are using, or to a setup screen for your unnamed Wi Fi client. She still has the original box that the computer came in along with a bunch of discs, including the Driver Recovery CD.
I can't provide a screen shot to illustrate how to do that because I don't know if you are using the built-in Windows Wireless Zero Config, or a vendor specific utility for your unnamed Wi Fi card.
While the modem seems to be operating properly, on her laptop, the only computer she has, running Windows XP, when connecting to the wireless network, at the bottom of the screen, I get an [endless] message, Windows was unable to find a certificate to log you onto the **** network.
At the top of the screen, where it says, Choose a wireless network, I get an [endless] Validating identity.
