Thanks for all the tips. Now I've just got to find out why the router is doing this. Firmware upgrade or configuration settings I suupose.

I upgraded the firmware last night but still having same problem. Power resetting the modem didn't help either. I honestly don't see any settings on the router that would cause this. Next step is to contact Motorola.

Yeah, I think that's your best bet. Did you find out if it's still under warranty?

Essentially the WAN side (cable) will now pickup the DHCP address which used to be directed to your PC and the LAN side will be assigned an internal private address that will either perform NAT if you have multiple public IPs or PAT (most likely).

Sound to me like an arp cache problem on return traffic.

I can't see any other reason why you router would stop passing traffic to your PC but start again once the machince is reset or when you enable, then disable the MAC cloning option.

Basically when you do either of these things the CAM table of the switch is clear along with any arp entries associated with those MAC addresses.

The problem has to reside somewhere at the MAC/LLC layer (layer 2 of the OSI model) or on some layer offering support to both layer 2 and 3 like ARP.

Just out of curiousity, is there a setting in your router to clear the arp cache?

Update: I upgraded to the latest version of ZoneAlarm and the problem seems to have gone away. The PC has been on for 4 days straight without a reboot and the internet works everytime I've tried it. Thanks to all of you for your advice.
