I had been using the wireless filter to allow access to the wireless for only my desktop and printer. I had both of those MACs listed and the filter enabled and it was working fine.
But my new laptop cannot connect when I have its MAC listed in the list. I'm pretty sure I am using the correct MAC address. It is the one listed in the Tomato Firmware under "MAC Address" as "Computers MAC Address". I also used Command Prompt and "getmac", so I'm pretty sure I have the correct MAC Address.
That laptop is using Windows 7 Home Premium if that matters. Thanks
