@woozle that's why I tried to update my previous reply but something is not OK. I found the problem with Android 14 devices and I updated the solution. Thanks for assisting.

@woozle that's why I have edited my previous comment. It's another device. I think I have clue why my Android 14 has issues connecting. The 2.4 GHz network is detected as type Wi-Fi 6 .

I will try to find any way to troubleshoot the latency issues observed on the android device and revert back if I find anything.

@woozle I'm still investigating. It could be is other device as the MAC '00:90:27:E5:90:C6' doesn't match the Internet port MAC address of the BE550 but I'm not ruling any other interface on it....

Seems the issue is not fully resolved as the router responds on both the IP from my network (10.X.X.20) and 192.168.1.1 . If my gateway was configured to be 192.168.1.1, it would lead to an outage.

What worked for me: 1. Full factory reset 2. Login with the credentials written on the router 3. Pass the setup Wizard 4. Validate 2.4Ghz and 5Ghz works 5. Change Operation to Access point mode 6....
