Ah, I'll tether. Something I've never really done before. On Android it's pretty simple to set up. From the data connected device (my phone):
- More Options (under data usage)
- Tethering & Portable HotSpot
Then check mark the Portable WiFi hotspot.
It'll go through some settings like setting up a password etc. for the wifi name.
On the other device (my tablet) you can just go into the WiFi settings and connect.
But it brought a bit of trepidation for me. As soon as my tablet would connect to WiFi it would start all of it's syncing services. Probably not a lot, but if you're counting your MB for your dataplan, you may not want your tablet drinking data away without any restriction.
Well, there's an option for that, thanks to a tip from +Alex Dobie over at +Android Central there's a hidden option in your device to get it to 'sip' rather than chug.
The setting is hidden away under the Data Usage option (Menu / Settings / Data Usage) and then hit the action menu (the 3 vertical dots) to bring up another menu. One of the options is for Mobile Hotspots. Click that and you're given a list of WiFi routers you've connected to in the past. If one of them was a tetherable device (say my phone WiFi signal) you can click it. From then on the device will know not to go hogwild with the data while connected.
