WNDAP660 Connectivity Issues
I'll try to keep this story as short as possible. I run a small office and about two years ago I upgraded an older netgear G only access point to a newer WN203. All was well for about a year. Then I...
So since the firmware upgrade and a factory reset this has been working.
Hi esaym,
Welcome to the community! :)
Kindly try to disable WMM Powersave on the WNDAP660. Here are the steps below:
1. On the web-GUI of the WNDAP660, go to Configuration > Wireless > Basic > QoS Settings. The QoS Settings screen displays.
2. Click on the 802.11b/bg/ng tab.
3. Click 'Disable' on the WMM Powersave.
4. Click Apply.
5. Still on the QoS Settings screen, click on 802.11a/na tab.
6. Click 'Disable' on the WMM Powersave.
7. Click Apply.
Observe if this resolves the problem. Let us know the results.

I just want to follow-up on this. Were you able to disable WMM Powersave on the WNDAP660? If yes, what are your observations?

As far as I know the "WMM Powersave" option only enables or disables U-APSD (Unscheduled Automatic Power Save Delivery) which according to the packet captures I have done, no devices on my network are using it. All mobile devices seem to use the regular ps-poll method. I have tried disabling the option in the past and it made no difference. The only thing that seems to prevent the issue is disabling AMPDU under the advance wifi settings. But AMPDU is the main feature of 802n so disabling that is almost the same as setting the AP in 802g mode.
A new mobile device was added to the WLAN yesterday as well, an LG G5. I noticed that if I ping flood that device as demonstrated in my video above, it too will also cause the entire WLAN to stay locked up until the device is disassociated and reassociated.Originally I thought this issue might just be caused by buggy wifi on samsung devices, but with the behavior happening on the LG G5, that doesn't seem the case. The only thing in common is the Samsung S6 and LG G5 have wifi 802ac capabilities.
Can you provide the configuration file of your WNDAP660? You may provide me a download link for it.

A link to the config: http://ow.ly/ybjC307xhpz
wifi0 is the 2.5GHZ interface which I have disabled ampdu and set all the cell phones with wifi to only to connect to that interface. All other devices connect using the 5GHZ wifi1 interface. It is mostly default settings except I disabled the 40mhz channel option. In my previous testing, I had changed every combination of rtsThreshold, fragLength, and ampduAggrLength. Nothing made a difference. I didn't test disabling wmmSupport, but as far as I know, wmm is required for 802n which means disabling it would reduce throughput greatly.
My current configuration is stable (cell phones on wifi0 with ampdu disabled and everything else on wifi1 with defaults). But this should not be necessary for a $300 enterprise AP.
