OK, I am a bad bad man. I have never upgraded the firmware on my DIR-655 A1 currently running Firmware 1.0. When I try to upgrade the firmware to 1.10 (or any for that matter) it tells me the file is corrupt or not for this router. I'm not dumb, I know how to download items. Do the firmware updates have to be done in order? And If so where can I find the firmware between 1.00 and 1.10.
