I have a Linksys Wrt54g wireless router. It has worked fine for 9 months. I have it connected to a cable mode.
Last week I began to lose internet connectivity from all three computers in the house via the wireless. When I lose the connectivity I can see that my normal comcast IP address has been changed to 169.254.20.79.
I disconnected the wireless router and wired my cable modem to one machine and that worked without failure for one week. I reconnected the wireless tonight and the internet connection dropped after five minutes. I lost both my wired and wireless connectivity as again the cable modem showed a non-comcast IP address. Any help would be appreciated!

If I remember correctly, these cable modems are either static or dynamicly assigned IP addresses by the ISP. If it is a static IP modem, then something is wrong in the modem. If it is dynamically assigned, then Comcast is assigning a bad IP. Either way, why not call Comcast and run it by their tech guys. Sounds like it is nothing on your side and Comcast needs to look into it. Just a thought.
