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.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.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.
One way to restore networking, especially wireless, is to go into control panel, system and delete the network card. Since you mentioned that this notebook had previously been setup for multiple wireless profiles, my suggestion would be to delete all existing wireless profiles and see if that allows you to then create a new profile for the Comcast gateway.Now click on the Wireless Networks tab and select the network in the list at the bottom.Click on Properties once you select the wireless network that is having problems.Once I discovered it, I decided to post it here on HMR so that everyone can have it.The problem arises in Windows XP while trying to connect to a secured network, often on a D-link router.Also, since I was able to connect from my laptop with no problem, it led me to believe it was something wrong with my desktop.
