No internet access, wired or wireless, with WRT150N

[bleached]

I have a Webstar DPC2100 cable modem feeding into a WRT150N router. Up until yesterday it has been working fine wirelessly. This morning there was no connection, even wired. I reinstalled everything, more than once, checked all the settings, nothing appears out of the ordinary. I can connect to the internet directly through the cable modem. When I feed through the router, it all appears functional, the router correctly determines the dynamic IP address, but I have no access. In this configuration, I can still, directly wired through the router, access my MediaSmart home server. Any suggestions?

When I feed through the router, it all appears functional, the router correctly determines the dynamic IP address, but
(1) I have no access. In this configuration,
I can still, directly wired through the router,
(2) access my MediaSmart home server. Any suggestions?

So (2) says your file/print sharing is working and (1) says your browser will not ??

report your ipconfig /all results and run these:

echo ipconfig /flushdns >flushDNS.bat
echo net stop "DNS Client" >>flushDNS.bat
echo net start "DNS Client" >>flushDNS.bat
.\flushDNS.bat
