BE805 unstable with AP-mode
BE805 unstable with AP-mode
I have two BE805 setting as below.
HN8255Ws: ONU+Router
TL-SX105: TP-Link 10G Switching Hub
Network Speed: 10G
HN8255Ws -> TL-SX105(Main) -> BE805 (AP-Mode)
-> TL-SX105(Sub) -> BE805 (AP-Mode)
I was using Buffalo AirStation WXR-11000XE12 before using BE805 without any problems.
But after importing BE805, the whole network became unstable.
If you just rebooted anything (including ONU, BE805, devices just like iPhone, Macbook Pro), everything is OK.
But after using several hours, the whole network became unstable with the problem below.
1, Network speed on every device became very very slow especially on 6Ghz. ( For Example, on iPhone 15 Pro Max, it suddenly became to 2Mbps from 1800Mbps)
2, Sometimes devices can not connect to 6Ghz SSID (5Ghz and 2.4Ghz can be connected).
3, When issue happens, either of the two BE805 has the same issue.
4, After rebooting everything, the issue gone for hours but will happen again.
I also tried beta firmware that the support team sent to me. But didn't work.
I tried everything I can to troubleshoot the issue below but still can not resolve the problems.
1, Reset and reboot everything.
2, Change DNS server to 1.1.1.1 or 8.8.8.8 or 9.9.9.9 or My ISP default.
3, On/Off Flow Controller
4, Changing Wi-Fi setting.
5, Changing Lan Cable.
6, Via or not via switting hub.
7, On/Off IPv6
I see in Router-Mode, there are settings for IGMP proxy and IGMP snooping, but on AP-Mode there's no setting about this.
You know the router on AP-Mode should be default OFF.
I am considering if it has been set to ON even in AP-Mode ( I can not see it as there is no UI in AP-Mode)
BE805 seems to control multicast distribution in AP-Mode.
The support team told be they can troubleshooting via TeamViewer only on workday,
But I don't have time on workday and when the issue happens everything is slow including TeamViewer, it's hard to troubleshoot the issue via Internet?
Is there a firmware that can let user set IGMP in AP-Mode or a firmware setting every setting related IGMP to OFF?
Or if you know any other things that may make the issue, please let me know.
Thank you very much.

Sorry to resurrect an old thread. By any chance, is the setting "OFDMA+MU-MIMO" turned on?
I've confirmed that in my current home set up, my network encounters all sorts of odd drop-out problems after several days or hours when the setting "OFDMA+MU-MIMO" is enabled. Trying out "OFDMA only" right now and observing. Before trying these, disabling both caused zero problems for the multi-floor network over three BE805s, but Open Speed Test results were worse of course.

Hi Corpski,
Yes, I always set "OFDMA+MU-MIMO" turned on to get a better speed.
I also use three BE805s but one for Router and two for AP. I also searched on twitter that someone said if using BE805 as Router mode, it will be stable. But I can't set all three BE805s to Router mode.
And the engineer from TP-Link told me that the reason may be A-MSDU which is an old solution for 802.11n but may be still effective for 802.11ac or later.
They sent me a beta version firmware which set A-MSDU to off and this absolutely resolved the speed dropping problem.
And I also tried to set all the IPv6 to off on official firmware, it also worked.(I don't know the reason)
So I think there must be a bug or something wrong on MAC address and IP Address changing.
Hope this help you. (Although the problem is still there on official latest firmware.)

Thanks for all this information. I would like to experiment more but currently have stable performance on all my BE805s right now. I look forward to seeing the next firmware release then.
Out of curiosity, may I ask why you are unable to run all of your units in router mode?
I run all three in router mode all with different static IP addresses assigned, with a single SSIDs for everything. Naturally, not all of them have a connection going into the WAN port but that is ok. I can run two of them in AP mode as well but I find that I have more configuration options available in router mode.
Just curious to know what conditions are there that force you to run two of them in AP mode.

Running all of them in router mode caused devices get different IP address when moving from one BE805 to another one.
If running on AP mode, although sometimes it cutting connections but it recovers quickly than running on router mode under 802.11kvr .
Currently speed dropping problems are temporarily resolved in beta firmware.( other problem such as sometimes 2.4ghz and 5ghz SSID disappear is still there...)

I see. I don't notice this because all my wireless devices are set to manual IP address, gateway, DNS, etc. given the same SSID. Glad to hear the changes coming with the new firmware but concerned regarding the 2.4 ghz / 5ghz SSID disappearance. So far my problem hasn't recurred, though at the cost of turning MU-MIMO off for now.

I see, it seems that router mode is more stable than ap mode and also can config more. And SSID disappearing problem seems only occurs in ap mode
Engineers are still investigating the reason,hope we can get a more stable firmware soon.
