Router with Static IP looses WAN connection

    I have used the WRT54G for several months with very few problems. During that time, my ISP assigned me a dynamic address. I recently obtained a static IP address from my ISP. I entered all the necessary information into the router and things woked fine, but not for long. At random times, the router/AP losses the ability to connect to the WAN. I can not connect via the hard-wire or the WLAN. When it is in this mode, I must login to the router and change it from a static IP to a dynamic IP and then back to the static IP and then things work fine for awhile. When the router is locked out from the WAN, I can still access any computer on my home network but I can not ping anything beyond the router.

    I have tried several things: Latest Firmware, power cycling the Router, switch, and computer nothing helps but to change the IP.

    My ISP believes this is a router problem because if I directly connect a PC to the ISP, bypassing the router, it never losses connection to my ISP.

    What I need is some ideas of where to look to help diagnose this problem and of-course any possible solutions.

    Thanks

    Which wireless card are you using?

    I am using several, but when the "internet" (i.e. WAN) disappears, it is gone for everything, hardwired (LAN) and Wireless (WLAN). I can still access the router through either the LAN or WLAN, but can't get to my ISP?

    Seems to happen about once or twice a day.

    Okay, I am still having this problem. This morning I accessed my system from work and it serverd up the web pages as expected then it quit. I had WallWatcher running and below is the last few minutes from it.

    One very strange thing is that when I got home the system was working but www.whatismyip.com shows a different IP than what was programmed into it. Does this help anyone with some ideas??

    Some things:

    65.73.236.3 = DNS1
    63.76.119.3 = DNS2
    My router IP is 192.168.2.1
    WW is on 192.168.2.100

    Nothing is 192.168.2.255
