re copy and paste:
On your PC search and download a program called putty.exe. It’s a nice simple standalone executable.
run it and select the „ssh“ connection type. Type in the IP address of the PI, and hit open. Accept the key and log in.
You should be able to copy and paste from the putty window, by selecting the text from the putty window (to copy), and then hitting Ctrl-V
(to paste) in another window.
Are you saying that:
Ioctl[RTL_IOCTL_HOSTAPD]: Invalid argument
is the only response from that command?
