Thanks for the script: I do have a question because of the way I am trying to use this script. I am using the python script as a cgi page. I can't seem to connect to the web from there. The idea is to have users connect to a hotspot through a Raspberry Pi and then they can connect the device to a wifi network via the script on the page. Can you help?

Thanks. Unfortunately, I ran into a problem. I loaded wifi 'pip install wifi' earlier today. The error I got running the module, following the command, is:

python wifi_taylor.py

Please advise.
Thanks. again.

Why am I getting this error? Cant I use this in windows 10? I am new to python. Please let me know soon. Thanks

I am getting an error like this. wifi.exceptions.InterfaceError: b"wlan0 Interface doesn't support scanning.".
Any help is appreciated.

run ifconfig , and see ur interface, it is likely not wlan0, but something like wlp2s0

Did you find solution for this

It is because you are on windows 10.
I am looking for the interface to enter for windows 10 too ...

did you found any solution?

subprocess.check_output(["netsh", "wlan", "show", "network"])

      Hi, I am getting this error. What may be wrong?

Any solution for the returned non-zero error returned by the scheme.activate() method?
