@David-TP 
- my phone google pixel 9 pro,  from deco app, mesh technology = on, preffered deco = auto, band = audo
- very easy to reproduce it's happen in my bathroom every single time 

additional feedback
- wifi backhaul show 5Ghz and 6Ghz on high capacity mode, but i didn't enable 6Ghz network 
- i have one x50 outdoor using wifi backhaul show both 5Ghz and 2.4 Ghz even set to capacity mode

ask again , beamforming feature should enable or not ? 

  @David-TP 

cool david, everything clear. 

few days now with 1.2 sofar so good

for the case,  internet access stop when my phone roam to different deco at some spot in my house 
what i can see is 
my bath room is very near to main deco at hallway just one wall in between and there is hole for vent fan on that wall between bathroom and main deco
everytime i  enter bathroom, phone roam to main deco hallway which signal max strong but cant access internet . 
after on/off wifi  on my phone ,seem connect back to living room deco which is much weaker wifi signal but internet access is ok
between main deco hallway and living room deco is Ethernet backhaul 

the other thing i just notice is 
signal strength for BE85 is much weaker than X50 outdoor 
there is one vigi wifi camera and the back of the house , x50 outdoor at the front gate, be85 in between.

i havn't set preferred deco for this camera, this camera always connect to X50 which is double the distance than BE85, connection stable only slow and no disconnected
 but when i set preferred deco to BE85, camera connect to this BE85 but connection keep disconnect and connect back  by itself all the time , i got offline notification from VIGI app almost every 15 min. 
between vigi > be85 > x50 is open space no obstacles, 
i'll try to enable beam forming , it's disabled because on 1.1.3 enable it , thing got worst for my case.

not sure if there is anything to do on signal strength power setting like many WIFI device can adjust or not ?

best regards

Anybody encounter incorrect/outdated internal LAN IP address shown on the app?

Using BE85 loaded with FW v1.2.0 DECO App from Google Playstore v3.9.98

For example: - My desktop connected via LAN cable has been disconnected and yet the APP still show the unit IP address under client list -

Another desktop connected via LAN cable shown an IP 192.168.68.57. However, using Windows -> cmd -> ipconfig -> 192.168.68.55

From the above, I thought the issue seems to plague devices connected by cable. However, I realized some wireless devices also exhibit the same issue. All those devices are completely power down with even power cord removed from socket.

I do not remember or under the impression v1.1.3 having such issue and it seems to happen with 1.2.0.

Any workaround to the above?

  @David-TP After the update my satellite BE85 indicates a problem that ethernet backhaul is slow and it seems to be restricted to 100Mbit instead of 10Gbit ... Before the upgrade everything was fine, so there is NO problem with a cable or anything else.

The satellite BE85 is directly connected to my main BE85 via 10Gbit ethernet cable. 

I have already tried to restart everything but this does not change anything. 

Do you have any idea what I can do to get the full ethernet backhaul speed back again?

Hello, David.

The update to v1.2.0 has resolved all of the following issues.
In my environment, it was a godsend of an update.
Thank you very much.

The issue with pairing the WLI-UTX-AG300 with the Deco BE85 was caused by the WLI-UTX-AG300 being an older model and not supporting WPA3 Wi-Fi security.  
By changing the security settings for the 2.4GHz and 5GHz networks to WPA/WPA2 in the Deco app and then performing WPS pairing, the connection was established.  

It is now functioning properly as the main router rather than a bridge connection.

We look forward to future updates.

  @David-TP My BE85 is currently on 1.1.1 Build 20241023 Rel 34667, and that is the latest version for me, not sure about other regions - can i upgrade to 1.2.0 ?
