So heres the deal, I am running XP on my Dell laptop, went out last week and bought the Linksys wireless-G router and the wireless-G card, everything was working fine, and I have a Motorolla cable modem with Comcast as my ISP, this morning while trying to connect to my wireless it takes longer than normal and I get the message "aquiring network address" then once connected I cannot access the internet. After hours of messing around with it I call comcast who has me go into my lan connection, go down to TCP/IP click properties and ask what my IP address is. I tell him it starts with 192. and he tells me that is a router address and that I need to click obtain IP address automatically, and the reason is that Comcast periodically changes the IP address, now I work while hard wired in, but cannot get the thing to connect using the router, and that is because the IP address has changed. Any help here would be appricated.

1. The network interface you used when you setup your Comcast account has the MAC address you should enter in your router's configuratin. Comcast uses that MAC address to verify that you are authorized to access their network. Clone that MAC address to the router's WAN port. You can run ipconfig/all at the command prompt to see the MAC addresses of your computer's network interfaces. 2. Make sure you've setup the router to receive its connection info dynamically from your ISP. Your router will periodically "lease" an IP address from Comcast's DHCP server. If Comcast changes your IP address, your router should have no problems acquiring and using the new connection info. "If it ain't broke, upgrade anyway."
