My last one was exactly the same. I bought this one and have had no problems so far. Unfortunately, it doesn't work without a battery.
I would place it in a place where there are no strong temperature differences. This way the problem should not occur. e.g. inside close to the window for connection.
Hello, in principle yes, unless your Mac is so old that it does not support these WLAN standards.

What Mac model do you have? Greetings
Of course you can, that's what the device is made for. But of course you need an additional data SIM if you want to use it in your tablet when you are on the move.
