Good morning,
I can add another attempt.
I performed a factory reset to Buddy 6 and a reacquisition in the wifi system but no luck. Same behaviour.
It seems that the phone, when leaves the Titan v3 and it is located near the Buddy 6, can no more receive the IP address. Sort of a DHCP problem between controller and extender?
The roaming is stuck on cellular networ, and if I try, on the phone, to tap on the wifi (hence forcing a manual connection), the phone is stuck on "Obtaining an IP address...."
Also after a switch off/switch on of wifi on phone do not resolve the issue. Always "Obtaining an IP address...."
Only if a I go downstairs near the Titan v3, it connect successfully to the wifi network.
After this reconnection if i turn off the wifi, go upstairs near the Buddy 6 and switch on the phone wifi it connect successfully!
I would to remember: if all operations above are made in a wifi segment with 802.11ax standard I haven't any issue.
Best regards
