wi fi - Can tablets differentiate between regular wi-fi and mobile hot spot?



There are a lot of apps in Android which act differently depending on the internet connection. Such as apps which auto-upload photos to the could only when connected to Wi-Fi, and not when connected to broadband on a smart-phone.


Unfortunately, when such apps connect to a mobile hot-spot (limited data; tethering), they think it is regular (unlimited data) Wi-Fi, and work accordingly.


Is there any way for a tablet to notice when a Wi-Fi connection is from a mobile hot spot, and act as if it was connected to broadband?



Answer



If your tablet (or phone) devices are Android version 4.1 (or newer) then you can tell them that a particular wifi connection is a hotspot rather than broadband, which will let apps know that they should limit the traffic they use.


On the Android 4.1+ devices, if you go into Settings -> Data Usage and then press Menu (or press the "..." overflow button) you should see an option called "Mobile Hotspots".


Data Usage Menu


In here should be a list of all the wifi networks that the device has connected to recently, with a tickbox alongside that you can select to say that the network is actually a mobile hotspot. This tells your phone to treat that wifi network as if it is a mobile data (eg 3G) network instead of a broadband connection.
