Raspberry Pi wlan connection loss

Mon Nov 19, 2018 8:14 am

Hi,
I have a Raspberry Pi 3, running as an AP. Things work well for serveral minutes, then some clients get dropped. If they try to go to a page on the web server on the pi, the http request does not even get to the web server.

In the syslog, I see messages such as:
Nov 17 06:29:40 100 hostapd: wlan0: STA c0:f4:e6:bf:62:f9 IEEE 802.11: disassociated
Nov 17 06:29:40 100 hostapd: wlan0: STA c0:f4:e6:bf:62:f9 IEEE 802.11: disassociated
Nov 17 06:29:40 100 hostapd: wlan0: STA c0:f4:e6:bf:62:f9 IEEE 802.11: disassociated
Nov 17 06:29:40 100 hostapd: wlan0: STA c0:f4:e6:bf:62:f9 IEEE 802.11: disassociated

Not sure if the above are relevant to the problem.

How would I go about trouble shooting this and narrowing down the problem?

Thanks

Try disabling power management on wlan0.
Run hostapd in the foreground in verbose mode you might see something of interest.
