I am on latest snapshot:
Powered by LuCI Master (git-17.194.28316-2224714) / LEDE Reboot SNAPSHOT r4610-97eb8ab 

Try stable version earlier, the snapshot last longer before wifi down. But still, after few random hours wifi still down. I have not dig too deep into the sysem log, but what is clear to me is that I got plenty of:

Mon Jul 24 00:31:40 2017 daemon.notice hostapd: wlan0-2: STA 00:25:9c:c9:1a:b6 IEEE 802.11: did not acknowledge authentication response
Mon Jul 24 00:31:43 2017 daemon.notice hostapd: wlan0-2: STA 00:25:9c:c9:1a:b6 IEEE 802.11: did not acknowledge authentication response
Mon Jul 24 00:31:46 2017 daemon.notice hostapd: wlan0-2: STA 00:25:9c:c9:1a:b6 IEEE 802.11: did not acknowledge authentication response

like few hundreds line of it, got nothing wrong on kernel log.
