Hawking Wireless-G Router Causes Internet to Cut Out

Hi there,
I just installed a Hawking Wireless-G Router (HWR54G). Before that I
was using a Belkin 5 port network switch with connection sharing. I'm
using Verizon DSL. Now, my internet cuts out intermittently every few
minutes. It immediately reconnects, but I'm plagued by chronic
internet "hiccoughs."
I know that some don't believe this router is compatible with Verizon
online, but I am using PPPoE, not WinPoET.
Your advice please.
