Why was my bridge for ipad shut down? - Tablets & eReaders

Are you sure of Wifi password is correct?
if so, 1st; try restarting your ipad by holding down power/sleep button untill it show "Slide to shut down" leave it off for 10 seconds & then re-open it.enter the Wifi -password, sometimes this step works.

2nd solution ; try resetting your iPad network settings, it will not affect your ipad in any thing except it will forget all entered passwords for any wifi you have already connected before. go to General from Setting, choose resett, and inside only reset network setting, shut down ipad & try to connect to the wifi again. Hope this solution work for you. Also you may try shutting down & opening your router again after 10 seconds while off. Good Luck.

Rebooting is easy. It is called a hard reboot. Just hold both buttons down until you see a red slider, and then slide it to shut down. It will restart, and you will see the Apple logo.

Try removing the battery for 30 seconds.

Connect it to your PC and start iTunes. Select the ipad in iTunes and see if it comes back on.

Double-click the Home button and you will see small windows of all the Apps that are currently open. Swipe upwards on one of these windows and it should close. You can continue this process on any other Apps that you wish to close.

I would first try doing a hard reset. Hold the home and power button down simultaneously until the iPad completely turns off and the Apple logo appears. You can ignore the slide to turn off button when it appears.
If that doesn't solve the issue I would make an appointment with your local Apple Store and have the device checked out by an Apple Genius.
Hope that helps!

It seems that you've already tried reset (holding the home and power buttons, right?) the iPad and it does not work.

So you may need to connect your iPad to your computer and do a factory restore using iTunes.

Step 1
To reset the Apple iPad you should first locate the power button. This is the button on the top right corner of the iPad when you are holding it like a book, with the narrower sides on the top and bottom.
Step 2
Once you have located this button you will need to simply hold this button down for about 3 seconds or until you see the red slider icon (a red rectangle with a white arrow facing toward the right) come across the top of the screen. The slide area or the area to the right of the button will be labeled Slide to Power Off.
Step 3
If you want to just reboot to iPad you can do that by touching the red slider button and sliding your finger along the slider area toward the right side of your iPad. The iPad will automatically start shutting down, it may take it several seconds depending on the amount of space you are using on your iPad and the programs you had running when you requested the reboot.
Step 4
To turn the iPad back on or restart it after you have shut it down just press the power button (remember that's the button on the top right of the iPad).

If you haven't already done so, you have to download the Pogo application from the iTunes app store. If your problem is with the app itself, the first step would be to reboot your device. To reboot the iPad, hold down the button on the top of the iPad until you get the option to shut down the device. Once shut down, press the same button to power on the iPad. Test the Pogo app to see if it works now.
