Not sure what you mean that you are using “legacy bluetooth since it was on FW4”.
This is a quote about FW4 by HandyAlexander, a product rep for the TheHandy.
At the same time you are talking about networks (WiFi). I recall that some users have had issues when there were multiple networks. Can’t find the posts about it though and see how they solved it. Someone had to simplify their network SSID for it to work.
Another user realized that the network signal was too weak. The network was found but that was it. By moving closer to the router the issue was resolved.
Hotspot networks can also be a bit tricky. Someone had to change a setting on iPhone 12 for it to work.
