and enter your router model number. It will pop up a link for the latest DD-WRT image for your model. READ THE INSTRUCTIONS and visit the "Community" chat boards before you start. You need the "factory-to-ddwrt" version to flash from the Trendnet GUI, then the other straight "model-firmware.bin" file to upgrade once the unit has been flashed the first time. You can easily turn your router into a doorstop by missing a step and neither Trendnet, the DD-WRT folks, nor myself will accept any responsibility if that happens. Also a word of advice, do NOT set the transmit power to max and expect a great signal. Most home routers operate very poorly at max output. Back off about 3 db for much better results.
