Re: Edison AP mode in 5GHz

In default Edison kernel, Regulatory DB is disabled.
So it is not allowed to use channel in 5Ghz area.

This is steps what I tried to set 5Ghz channel for hostapd.

1. Enable Regulatory DB in Kernel

See this link:
http://wireless.kernel.org/en/developers/Regulatory/CRDA#CONFIG_CFG80211_INTERNAL_REGDB

2. Rebuild kernel and update edison image with new kernel

3. Modify /etc/hostapd/hostapd.conf
For example, setting channel 44 in Korea.(channel 44: 5220 Mhz)
Set "country_code=KR"
Set "hw_mode=a"
Set "channel=44"

4. run hostapd
systemctl stop wpa_supplicant
systemctl start hostapd

You can check available channels using this command and use those channels.
"iw list"

Thanks,
