Webserver connectivity problems

[elm669]

Hey guys, I'm having trouble with my webserver and this Linksys wireless router. Here is my site. The connection has been on off and wreaking havoc on the server and the dyndns that worked just fine with the old netgear RP14v. Anyone have any ideas why the router is working off and on and not keeping up with the dyndns?

Model is: Linksys Wireless-G Broadband Router WRK54G
