Pros: Excellent router: powerful, and feature-rich. Can't comment on the factory firmware because I installed DD-WRT v24 Mega on it as soon as it arrived. Works beautifully with DD-WRT Mega.

Cons: Would be nice if it supported Gigabit Ethernet.

Overall Review: There's a bug in the USB support in DD-WRT v24-sp1 which causes the router to fail in writing to a USB device. The problem has been resolved in the latest DD-WRT v24-sp2 SVN builds (which are technically still beta -- although there're more robust than sp1).
