Please Note I have Changed The Main Tittle Of The First Post..
Our New Car Connecting To Our Home WiFi Problems.I Have Removed The Word 'Hot Spot' as it is confusing matters.
I have four different TTF screens, The touch screen in the central dashboard area is the main one for doing lots of things (I have very few switches in the car
) It also contains a built in Web Browser and like a phone can have many apps etc.
It is also the place where I set up the Car Connecting to our Home WiFi.
Once it has connected to our Home WiFi (with Blank DNS fields)
The cars web browser will not work, Apps will not work, cars software * up-dates will not work or up-dating the Sat-Nav * will not work.
Note All These Work Using The 4G Data.
* = some of the up-dates can be quite large and that's why I wanted to use my unrestricted home internet as to the very Limited 4G data allowance of 500mb per month .
So my conclusion is because those DNS IP are missing it can not do 'reverse look up' and can not get on to the internet from our home WiFi.
I hope to get chance to call in the dealers next week and try connecting some of there cars on to there WiFi to see if it is a general problem or just with my car.
I will do some more tests later when I have cut the grass.
