How to connect multiple devices to openplotter Wi-Fi?

[PaddyB]

Are you using the internal wifi to create a hotspot and connect to  a network at the same time?

Doesn't work very well.

Yes, I do it!
Indeed, sometimes, by trying and trying again, it works, but it is not stable. So, what do I do?

Just use it as access point to see if it's better, should be!
