Great to hear that you are enjoying the first release of the firmware. We are working on getting USB support so transfering programs can be made easy for people without a WiFi connection. But for now let us try to fix your problem.
Please be aware that WiFi networks SSID’s and passwords are case sensitive. If you are still not able to get a working connection try to enable encryption with WPA2 (and password) – this is how I am using it so this should definitely work… please post the results of your test so we can fix potential bugs.
