cannot enable mode n in secured mesh while open mesh can

[lingyunli63]

hello, everyone i am using WNA1100 wifi usb dongles to build a mesh network on ubuntu 1604. WNA1100 uses AR9271 chip,which support b/g/n(150Mbps). ath9k_htc driver in the linux kernel supports this usb dongle.

the open mesh network without password is build successfully, with command below iw dev $meshdev set channel 3 HT40+ 802.11 n (150Mbps) is enabled.

however, using wpa_supplicant, the secured mesh network builds successfully. But, i cannot enable 802.11n. my wpa_supplicant.conf is blow.

ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=adm user_mpm=1 network={ ssid="llymesh" mode=5 frequency=2432 key_mgmt=SAE psk="securedpassword" }

the iw command is below, _iw dev $meshdev set channel 3 HT40+ ifconfig $meshdev 192.168.3.80 sudo ./wpa_supplicant-o11s-legacy/wpa_supplicant/wpa_supplicant -d -Dnl80211 -iwlx4494fc0f6ec8 -c wpasupplicant.conf -B

So how to enable mode n with wpa_supplicant? change another wifi card would help?

the wpa code is from Git clone https://github.com/cozybit/wpa_supplicant-o11s-legacy.git

Suggest that you use the latest wpa_supplicant hosted here: https://w1.fi/hostapd/
