I have a WRT350N. I was upgrading the firmware and I made the mistake of doing so on my laptop which was connected to the router wirelessly. During the upgrade the laptop lost connection to the router--obviously--and therefore interrupted the upgrade. Now I'm locked out of the router's setup page and I cannot restart the upgrade. I was told that there is a "back door" to this problem which would allow me to flash the firmware without accessing the router's setup page? Any help would be greatly appreciated. Thanks.
