WAP371: deauthenticated for reason 16 + authentication failure, reason 17
I have an issue with the WAP371 when I'm trying to download big files in the network or to stream media.
After a few gigs of download (at a rate of 40-45Mb/s), the transfer goes to zero Mb/s and then I have to wait for 1-2 minutes before I can start using the internet again... Each time I re-launch the transfer the same issue happens, so I can never complete big file transfers with this AP...
This happens on a laptop with Intel 7260 AC wifi card, on android smartphones (Samsung & LG) with AC wifi cards also, and also on the Lumia 2520 Windows RT tablet (Wifi N).
On the WAP371 logs the following appears:
hostapd STA xx:xx:xx:xx:xx:xx associated with BSSID yy:yy:yy:yy:yy:yy
hostapd Assoc request from xx:xx:xx:xx:xx:xx BSSID yy:yy:yy:yy:yy:yy SSID AP_NAME
hostapd STA xx:xx:xx:xx:xx:xx deauthenticated for reason 16: Group key handshake timeout
hostapd Station xx:xx:xx:xx:xx:xx had an authentication failure, reason 17
(I have hidden MAC addresses and SSID)
This happens even when there's only one client connected. After a reboot, I noticed I can download a file for longer (up to 15Gb) but it's still not enough for some of my files.
The WAP371 has the latest firmware (18.104.22.168) connected to a PoE+ switch (Netgear GS728TP).
The AP it replaces (a Netgear WNDAP660) worked flawlessly on the 5 GHz band (though only N, not AC wifi), connected to the same port of the same PoE+ switch...
Should I just return this AP or is there something I could try setting up?

tip is the ‘write default’ command on autonomous wireless access points,
it simplifies manual conversion of a WAP with a static ip address to a
