Wi-fi range of Time Capsule suddenly dropped
Hi
we recently bought and installed a Time Capsule 3TB, and it worked great for a month. The wi-fi covered the whole house. As of yesterday, we can only get the wi-fi signal when we are in same room as the Time Capsule! There are ZERO BARS anywhere else in the house.
Help! What could have happened? what can we do?
Thank you
