    Hi Airheads,

    Been working with a client for a few weeks on an issue where AP-505 running 

    We have test setup using WPA2-PSK, single band 5 GHz and only a single device (so no cluster)

    We've been experiencing an intermittent yet sometimes reproduceable issue where iOS device connected to WLAN will stop sending traffic after approx 15 mins connection time. 

    Android device connected at same time never skips a beat. 

    Have reproduced with 2 iOS devices (ios / ipad) but so far after several hours of logging investigation with TAC we're still at a loss. 

    Have also had issue with signal level showing 0 which we understand a defect exists (and we have proven disabling arm wids override fixes) but still seems that the IOS device issue seems to persist. 

    Issue seems to happen with HE disabled and enabled. Also seems to happy on both 2.4 and 5 GHz.

    Next step is raw WLAN pcaps but due to lockdown we can't access site. 

    Wondering if anybody else has had issues with WIFI6 AP's and IOS devices.
