I have moved house but my time capsule still shows the address of anything connected to it as my previous property.

I have been using my time capsule at a previous address for about 18 months. I have recently moved but the address on the time capsule hasn't changed. Whenever I connect an iPhone, iPad, iMac or any other location aware device to it now, it still thinks it's at the previous address. If I use a different router for testing purposes, the location on all my devices is correct.

Is there a way to reset the location stored in the time capsule? To be honest, I didn't know it stored an address but it clearly does.

Thanks a lot,

Niall
