I have a 2862n running firmware 3.8.9.1_BT at home.
In 'Wireless LAN >> General setup', I have the following settings:
Mode: Mixed (11g + 11n)
Channel: 11, 2462 MHz
Every 1 or 2 weeks the WiFi throughput drops to a crawl (< 1 Mbps). Restarting the 2862 cures the problem for a while.
Has anyone seen this issue before?
In case it helps diagnosis, when this problem happens the 2862n's syslog output contains loads of WLAN_DBG messages. E.g.:
2018-12-09 08:19:34 DrayTek: WLAN_DBG - WPA handshake start for [mac address of my nexus 7]
2018-12-09 08:19:34 DrayTek: WLAN_DBG - send MSG 4-1 packet in 4-way handshake

2018-12-09 08:20:20 DrayTek: WLAN_DBG - Wpa_session_stop
What do these messages mean?
Any help/suggestions gratefully received!
