I have the same router and have had that problem several times. Reset by unplugging the power for approx 10sec. (Im sure someone wrote that in comments above I didnt read them).

I use the dynamic IP and WPA/PSK w/NAT enabled. Also back up your router settings. Belkin routers have this nature in them to LOOSE connections sometimes and it almost seems that the BIOS or ROM chip fails sometimes. Might also change the wireless channel. That did help on my signal strength and it doesnt seem to loose the CONNECTION as often. Hello there, litespeed14.

Thanks for the advice but unfortunately...

I tried all you SAID and my status in the corner turned into "Not Connected" after I set it to a dynamic IP setting. So I restored and I'm back to scratch. It says I'm connected but I still can't OPEN any pages.

Anyone have any other suggestions?I'm sorry, can anyone help?Who is you Internet Service Provider? what is the brand name of your modem?
Have you tried turning OFF the modem and router wait like a minute then turn ON the modem 1st wait for 30SEC before you power ON the router...
What is the internet IP address on the router? Yes, I have tried that - no results.

ISP - Local Providers
Brand - Belkin 54g
