Ok, we will figure this out
Run GCC as an administrator. (Right click on the program and select run as administrator)
Create a new P4 and edit the connection to make sure it is a IP address and not Auto.
If that does now work remove the settings for access point mode and select WiFi modus (infrastructure) inside the P4.
Make sure you restart the P4 and then try to connect again.
If that still does not work, which I may not, because I did have an issue with my windows 10 surface laptop not connecting Via the GCC desktop software until I added it to the allowed apps and feature in windows firewall.
Start menu click settings, type in firewall in the find a settings search box
Click windows firewall in the search results click on allow an app or feature through windows firewall.
Once the allowed apps window pops up
Click change settings
Click now allow another program
Browse the the gcc executable
And click private and public
Click ok
And then try the gcc desktop app and see if it connects.
