OK, thanks for the information. I just picked up a cheap Belkin(model-F7D7302)for about $18, just for something to mess around with. Been having connectivity issues with an old Netgear WNR2000(v1)that(from what I’ve read anyway)does not support the alternative firmware. Might be changing ISP soon so wanted to hold off getting something newer/more expensive, for now.
That old NetGear isn’t in the support list, so it’s not likely to work with DD-WRT (most likely due to RAM/FLASH size constraints).
The F7D7302 IS supported and on the K26 (NEWD) firmware.
All of the instructions are there. Just do a little reading and make sure you’ve got everything printed out you need just in case anything problematic happens. You WILL enjoy it.
