I couldn't find I have the wpa_supplication.conf in the /etc/wpa_supplicant/ Besides, after this setting applied, does it mean if we could some scanning in iw wlan0 scan, then I can't see 5GHz???

You can tell wpa_supplicant tell what frequencies it should use, e.g. with scan_freq="2412 2437 2462". It won't ever scan on the 5 GHz frequencies if you only specify your 2.4 frequencies. Likewise you tell hostapd what frequency to use. Patching a driver for this? Shudder. :-) -------------- next part -------------- An HTML attachment was scrubbed...
