I've got a weird one. I had a Telstra data sim installed in the car for a few years which worked fine as a Wifi hotspot for connecting other devices. I have over the past few months had issues with Google Maps loading which I was told is because Audi's Google Map agreement had expired ?

Anyway - last month I changed phone providers and also swapped the Sim in the car to a Optus data sim. The weird thing is now Google Maps works again without any issues, but the Wifi Hotspot has issues. If I connect an iPad to it for example, it registers and logs on to the car wifi but does not receive any internet.

Anyone have any ideas to why?
