...but also say that I could perhaps use a more recent build of DD-WRT.
Questions:
Q1: What is the most recent build that will work on the DIR-601, and where can I find it?
Q2: Given that the router does not currently have DD-WRT, can I go straight to that build or do I need to install some other build first?
Q3: With a Linksys WRT54G-TM I needed to load a replacement CFE before flashing the router with DD-WRT. Why no mention of loading a replacement CFE with the D-Link DIR-601?
