No luck there, since this iPad is WiFi-only, doesn't have a simcard. All this troubleshooting is consuming too much time, so I've decided to let this aside until I try with the BT GPS. I've used the web interface to transfer between iPad and Windows laptop. You go to http://web.airdroid.com/, then you're shown a QR code. You scan this with the iPad's camera and that establishes the connection. Then you can transfer files. I think you can also set a password to avoid having to scan for every connection, but this is something I haven't tried. For your Mom's laptop it may be best to set the password to make it easier and hassle-free.
