I'm looking for something that lets me use my NAS as Wi-Fi accesspoint as well. It's got double ethernet and USB WLAN, so it should be fine. Alas it's not easy finding something that does both without setting everything up manually. Can anyone help?
Instead... just get something that will run OpenWRT. Check out this list: http://wiki.openwrt.org/toh/start. Running and configuring it at the command line is way more pleasant than you'd expect, and the (optional) web GUI is functional if inconsistent.
