MT7628: Clients keep disconnecting.

I have a HC5661A using MT7628. I've just test the latest commit e2eedc92 and it'…s very unstable. I connect my xperia phone to the wifi and it keeps disconnected around every 10 minutes. And the log keeps showing: ``` WPA: group key handshake completed (RSN) ``` I google for a solution and I added the followings to `/etc/config/wireless` ``` option wmm '0' option wpa_group_rekey '0' option wpa_pair_rekey '0' option wpa_master_rekey '0' ``` Things become better. But after 18-20 hours, clients disconnect again and the AP disappears from the air. I reference to the log and it shows: ``` hostapd: wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: disconnected due to excessive missing ACKs ``` I asked google for help again and added the following line to `/etc/config/wireless`: ``` option disassoc_low_ack '0' ``` After a few days testing, clients also keep disconnected, the log did not show something related to ACKs but: ``` hostapd: wlan0: STA 00:00:00:00:00:02 IEEE 802.11: disassociated due to inactivity daemon.info hostapd: wlan0: STA 00:00:00:00:00:02 IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE) daemon.notice hostapd: wlan0: AP-STA-DISCONNECTED xx:xx:xx:xx:xx:xx ``` BTW, when clients disconnected, only rebooting recover the AP. The full `/etc/config/wireless`: ``` config wifi-device 'radio0' option type 'mac80211' option channel '11' option hwmode '11g' option path 'platform/10300000.wmac' option htmode 'HT20' option country '00' option legacy_rates '1' config wifi-iface 'default_radio0' option device 'radio0' option network 'lan' option mode 'ap' option ssid 'LEDE' option wmm '0' option encryption 'psk-mixed' option key 'keep it secret' option wpa_group_rekey '0' option wpa_pair_rekey '0' option wpa_master_rekey '0' option disassoc_low_ack '0' ```
