Notes (about [PyPI]: wireless]):
Does not (yet) support Python 3: as somewhere in the code it uses the cmp function (which is only available in Python 2)
- I wanted to submit a pull request (as the fix is trivial), but apparently on GitHub it was already fixed, yet the PyPI repository was not updated (since 2016)
Does not work on Win (only Nix drivers are listed on the homepage - basically it only launches shell commands)
As a consequence, I'd suggest looking for alternatives:

Notes:
In order to create a POC I had to add some code (e.g. wireless_disconnect) not necessarily related to the question, which adds complexity.
BTW, the code is waaay more complex than I initially anticipated (that's why I didn't bother to explain it - as it would be an overkill), but I don't see any way of trimming it down
script00.bat (and time <nul) are just to prove in console that the code is connecting / disconnecting from the wireless network (and that I'm not connecting from Win in parallel)
- I don't know where the "*** 0***" part from
time 0<nul (in the output) comes from
As I specified, this is more like a POC, there are some limitations in (my and Win32Wifi) code. Some scenarios (networks) might not work without (small) code changes
Although connection to the network succeeds (and works), in the System Tray, the network status still appears as disconnected (actually for a fraction of a second it appears connected, but then it automatically changes). Also, the System Tray network icon shows as Connected. I'm not sure whether this is on my side (I forgot to somehow notify Win - although this doesn't make much sense), or Win doesn't like "someone else" to connect to wireless networks
THE MOST IMPORTANT ONE: The above code will not work OOTB, because Win32Wifi is buggy. I found 2 bugs that are fatal (critical) for this scenario, and a bunch of other smaller ones.
I've just submitted [GitHub]: kedos/win32wifi - Fixes (some critical) and improvements (merged on 200906, but no update on PyPI)
