No, I’m not going to switch languages but countrycodes. By default OpenWrt (and Piranha 3.0) ships with support for Wifi channels 1-11, but after reading the Madwifi documentation I was highly ambitious to change this and I finally succeeded. Fellow community members, we’re now able to utilize Wifi channels 1-14 or in other words: We’re going to speak Japanese by default as of the next Piranha 3.0 snapshot release (if that turns out to be stable)! There’s no need to wait though, you can enable Wifi channels 1-14 right now.

Actually, it’s that easy. Just reboot and enjoy! Opinions?

“Opinions?” HELL YEA *dances* I’ve been wanting to try ch 13 forever. Arigatou gozaimashita!
