Hello Community,
there is an ASCOM VoIP phone Mac=00:01:3E:18:89:53 which is disconnecting sometimes from WLAN SSID with simple WPA2-PSK.
Does anyone have an idea why this happens? Have a look at part of show tech:

Michael,
Based on the logs, I do not see any other issues other than Tx Beamforming, so I unfortunately do not have any other ideas as to why this is occurring.
Transmit Beamforming does have the ability to improve the signal for legacy clients, this is called "implicit beamforming". So, even though the VoIP phones are 802.11na, our APs will still try to use "Implicit Beamforming" to improve the signal for those devices when Transmit Beamforming is enabled.

Hi Zak,
thx for your information, but ASCOM VoIP Phones are connecting via Radio 802.11na 5GHz.
So disabling "transmit beamforming" shouldn't make a difference, am I right?
Do you have another advice?
Best regards
Michael

Hi Michael,
Looks like Transmit Beamforming is enabled and seem to be the reason clients are disassociating, I would try disabling this. This is found in any 802.11ac or 802.11ax mode radio profiles under "Advanced Settings">"Radio Settings".
The article below also has further info regarding Transmit Beamforming if you'd like to know more about this setting.
