Hello, I have Debian testing (buster) with hostapd 2:2.7+git20190128+0c1e29f-5 and I am facing an issue with client connections to the AP. When I start the hostapd daemon, then everything works fine. But after some random time (hours - weeks) of service running all the clients are disconnected and it is impossible to connect with any device to the AP again although the SSID is still visible for the devices with full signal. In the log I cannot see any hostapd lines at that time anymore. After hostapd daemon restart everything works fine again for some period of time until the issue occurs again. I did not see the issue before the Debian upgrade from oldstable (jessie) with hostapd 1:2.3-1+deb8u7 and exactly the same configuration. Here is a log of the last client connection: May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: authentication OK (open system) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-AUTHENTICATE.indication(xx:xx:xx:xx:xx:xx, OPEN_SYSTEM) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-DELETEKEYS.request(xx:xx:xx:xx:xx:xx) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: authenticated May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: association OK (aid 1) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: associated (aid 1) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-ASSOCIATE.indication(xx:xx:xx:xx:xx:xx) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-DELETEKEYS.request(xx:xx:xx:xx:xx:xx) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: binding station to interface 'wlp4s0' May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: event 1 notification May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: start authentication May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.1X: unauthorizing port May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: sending 1/4 msg of 4-Way Handshake May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: received EAPOL-Key frame (2/4 Pairwise) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: sending 3/4 msg of 4-Way Handshake May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: received EAPOL-Key frame (4/4 Pairwise) May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.1X: authorizing port May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx RADIUS: starting accounting session 81AFCCEFB2C57E28 May 20 16:00:53 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx WPA: pairwise key handshake completed (RSN) May 20 16:00:53 apuol dnsmasq-dhcp[476]: DHCPREQUEST(br-lan) 192.168.1.216 xx:xx:xx:xx:xx:xx May 20 16:00:53 apuol dnsmasq-dhcp[476]: DHCPACK(br-lan) 192.168.1.216 xx:xx:xx:xx:xx:xx iPad May 20 16:01:56 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: disconnected due to excessive missing ACKs May 20 16:01:56 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-DISASSOCIATE.indication(xx:xx:xx:xx:xx:xx, 34) May 20 16:01:56 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-DELETEKEYS.request(xx:xx:xx:xx:xx:xx) May 20 16:02:26 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE) May 20 16:02:26 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-DEAUTHENTICATE.indication(xx:xx:xx:xx:xx:xx, 2) May 20 16:02:26 apuol hostapd: wlp4s0: STA xx:xx:xx:xx:xx:xx MLME: MLME-DELETEKEYS.request(xx:xx:xx:xx:xx:xx) Here is the hostapd.conf file: interface=wlp4s0 bridge=br-lan driver=nl80211 country_code=CZ ieee80211d=1 hw_mode=g channel=6 ieee80211n=1 ctrl_interface=/var/run/hostapd ap_isolate=0 disassoc_low_ack=1 preamble=1 wmm_enabled=1 ignore_broadcast_ssid=0 uapsd_advertisement_enabled=1 wpa_passphrase=************ auth_algs=1 wpa=2 wpa_pairwise=CCMP ssid=MyNet wpa_key_mgmt=WPA-PSK okc=0 disable_pmksa_caching=1 bssid=04:f0:21:2e:5c:ec logger_syslog=-1 logger_syslog_level=0 Wireless card: Atheros AR9280 Linux kernel: 4.19.37 Any clue?
