I don't yet have my 502 hooked up and am using my SPA2102 in the interim, but I don't think it should make any difference.
Thanks Burris. Yes, I'm only plugging in the ATA WAN port into the Linksys router - no LAN.

To clarify...

My ISP supplies a static IP address to my cable modem, but my router uses DHCP to supply local IP addresses to my 3 computers, 2 DVRs, and the GS502.

For some reason, with the GS502, when the leases expire on the local IP addresses, the 502 and computers on my network clash, sometimes causing a conflict where they pull the same local IP address, making the 502 not work. I did not experience this with the 286 (or with the Linksys PAP2T when I had that)

Assigning a static IP address to the 502 with DHCP turned on did not fix the problem.
