I am working in two different locations, one with 35 ESPEasy + 10 Tasmota devices, one with three ESPEasy + 7 Tasmota devices. In one of the locations I changed the router from Telekom Speedport W925 to Fritzbox 7490. The Fritzbox 7490 had firmware 7.21 installed, the Fritzbox 7590 at home 7.01. In this combination I have had problems to get NETBIOS through the VPN (Which I built up formerly using a 7272 behind the Speedport) and I upgraded the 7590 to fw 7.21. NETBIOS started working again.
But instantly it seemed as if I had an almost complete breakdown of the far away WLAN with the 7590, it has been working stable for years before (It felt more stable with the old 7272 and FritzOS 6.84, but I was forced by the provider to change to 7590 due to changing the DSL from ADSL to VDSL). The location with the 7590 is 500km away so I started analyzing here in the small network using the 7490.
One of the ESPEasy devices I attached to my PC using the serial port.
Setting WLAN security of the 7490 to WPA+WPA2 (yes, I know, I shouldn't do this anymore) results in an almost unaccessible WebGui of the ESP.
Setting WLAN security to WPA2(CCMP) I can see the following log with recurring MQTT disconnections:

The device I've monitored reports a RSSI of -77dB, so its almost impossible to loose connection. I tried ESP_Easy_mega_20201130_normal_ESP8266_4M1M as well as ESP_Easy_mega_20201130_normal_alt_wifi_ESP8266_4M1M, Wemos D1 mini.
Due to compatibility for some old hardware at home, the 7590 was set to WPA+WPA2 - what a mess.
For me it looks like as if the FritzOS 7.21 with its huge changes of the different WLAN protocols including Mesh functionality causes the problems. Does anyone have similar observations?
