@chrisk @thetechnobear everything is working great - I was making a very silly mistake. I mixed up the concepts of an AP and connecting to an existing wifi network: while renaming the wifi.txt, I thought I was creating a new network for my computer to log in instead of connecting to my own home’s network.
I have two usbs, one running 3.0 and the other 3.1. It worked on both and, as mark said, the AP showing only while running the latter.
I’m sorry that I jumped to conclusions regarding the functionality of C&G’s dongle before actually understanding the concept and testing it. I’ll be more careful the next time.
thank you guys very much
