I have the SkyFi-USB wireless serial and usb adapter. Since my Samsung Galaxy Tab 4 cannot connect to an ad hoc wifi, I followed the instruction on your website to have my SkyFI-USB unit to connect to my home wi-fi network. It did not work. I tried several times making sure that I typed in the right password and it still does not work.
Android + SkyFi 2 + Joining an Existing Wi-Fi Network
