If you wait thru about an hour of automated atenndant h#$% you will be told about http://networking.belkin.com from this site you can access the firmware if it's available. It's not for the F5D7231-4P. The loaded fw is 1.00.02.test , this really gives me a warm feeling. I'm waiting on a second level support call back from Belkin. They said it would be 2-6 days before they called back.
