Hi, I am having a strange problem with Linksys WRT54G V4.20.7 router. Every couple of days, I start to experience problem accessing web pages. The DNS servers are not responding when I try to ping them. However, if I restart the router, the problem goes away. I have a Link RTP300 (for vonage) behind the WRT54G router. WRT54G is connected to the cable modem. I have contacted Linksys tech support but they were of no help. Anyone with this problem? any suggestion? thank you.
