My Pogoplug Thinks its in China?

I think I have to set a regulatory domain for my usb ath9k module because it appears to think it is in CN, which I’m assuming is China.

This can be changed with /sbin/iw reg set US. Once I did that, I got a lot more features listed with iw list:

Wow, that’s a lot better! But does it survive a restart? This post describes how to update crda (udev rules) and hostapd.conf.

Basically:

  1. add country_code=US to hostapd.conf.
  2. Edit /etc/default/crda so that REGDOMAIN=US
  3. Edit /etc/modules.d/cfg80211.conf and add “options cfg80211 ieee80211_regdom=US”

This is not a simple thing. I think I might have a busted regulatory.bin file?

Pogoplug now running hostapd

I was not anticipating it not being able to reach channel 11, so I set it to channel 1. Also, it cannot do 802.11n, so I set it to 802.11g. My cell phone seems to be able to use it.

Also, for some reason, my pogoplug syncs up to the same switch better than my laptop does. Using iperf on my laptop, I get a max of 95Mbps, yet on my pogoplug I get 180Mbps over the LAN. That is just too wierd.
