The 5660's DNS server isn't all that good. Sometimes it will not resolve the domain name to the IP properly and your browser tells you "site cannot be found" or something. If this is a constant problem for you, simply go to your Network control panel and manually enter your ISP's DNS servers into the TCP/IP settings.

---5260/5660 Users Note:
The above info is incorrect and based on the 5260/5660 not being properly configured with DNS entries from your ISP. Many people either skipped the DNS settings in the Router's DNS Server setup or they did not read the help file that explains to add your ISP DNS info into the 5660 settings when initially configuring it. You do not need to add the ISP DNS info in the individual LAN PCs TCP/IP properties as suggested above. Instead follow the steps in the Setup Guide here: »Efficient Networks Forum FAQ
