Lite and wireless adaptors (usb)

[Linxer2]

That all makes sense, but the desired connection I need is not with a wifi router, it is with a wireless hotspot. Most devices refer to its input/output as "wifi," though it isn't always the case. For this one, I am using mobile data on a phone and enabling a wireless extension of that data as a hotspot. USB tethering is unlikely mostly because I can never get it to work, on windows or linux for that matter. The network adapter picks up the hotspot, links to it, and allows me to use it for some time, (6 minutes), but then pretends after that it can never find this signal again, even if I were to totally reboot the entire phone (the hotspot). Rebooting linux remedies the issue, but again, only for 6 minutes.

I can't take a wifi router to work, and I don't use public wifi (I have my own reasons for that).
I think the problem is still with the iphone itself. This happens less often if not at all if the hotspot comes from an android phone...
