Just wanted to throw up a post saying that I got my Buffalo WHR-G125 flashed with version 1.17-ND of the Tomato Firmware. The whole tftp bit was necessary, but it turns out it’s not nearly as scary as I thought it might be.
The filename for the firmware I flashed was Tomato_1_17_ND.7z. You’ll wanna make sure you get the “ND” version (New Drivers) if you’re flashing a WHR-G125.
