Problem w/ Comcast / Linksys HELP

Specs: Windows XP
I have been living in my current apartment for over a year with the same network setup and had no problems, but this morning the internet would not work, so I unplugged the modem and the router thinking it would solve the problem to no avail. I called Comcast and they reset the cable modem, which seemed to solve the problem.

The desktop has internet, but despite the wireless connection being active and all the lights on the router being on where they should be, I cannot access the internet.

I went to go to the router's setup page to check the settings at 192.168.1.1 which is what it has always been to find out it no longer worked. I typed in "ipconfig /all" in the command prompt and this is what I got:

Tried to access the modem at the default gateway IP, could not get it to work. I've tried /release /renew to get the IP back public at 192.168.1.1 and had no luck. Called both Comcast and Linksys. No help.

I connected the ethernet cable from the router to a Mac laptop and checked the IP - it's 192.168.1.1 so I know the router isn't faulty. How can I fix this? Comcast uses dynamic IP.

Your ipconfig command shows an external IP address. The PC wasn't connected to the router when you ran it. 192.168.x.x addresses aren't public IPs.

That ipconfig is the result of a direct pc to modem connection. Check your wiring!!!

That's the same as the first one!

Modem > router > all devices?
