looking for a router than can be run with 100% free software
I am looking for a wireless router that supports IEEE 802.11n (draft) and gigabit ethernet. Well, there are some. But I want two more things: the router firmware must be free (as in speech) and it must be possible to flash the device with something like OpenWrt excluding any non-free software, but still with full functionality. Maybe there is a device that works with ath9k or otus?
I'm thinking you could use something like lifehacker?
I haven't used it myself, but have heard it's good.
However I'm not sure if it meets your second criteria ... working with OpenWrt. You'd have to check that one out.
