Jelly Bean :: Galaxy Tab 2 10.1 Reboots Continually If Allow It To Connect To Certain WiFi Network

I've had a Galaxy Tab 2 10.1 for just over a year. A few weeks ago, I updated to Android 4.2.2 whilst visiting my parent's house and it started continually rebooting itself. I did a factory reset (or two) before figuring out that it's entirely down to the WiFi. If I get in quick enough and don't allow it to connect, the problem stops, and it only occurs with the WiFi at my parent's house (though it always worked fine before the update). I've tried unplugging the WiFi repeater, which was a relatively new addition to the house, but it hasn't made a difference.
