how do i know if wifi extend is needed for time machine?
I suspect that my new Time Machine is dropping out when using WiFi. On my wife iMac in particular. We didn't have this trouble with the older Time Machine.
How can i test if the wifi signal is strong enough in case I need to relocate the Time Machine to the same room as our Macs or add a wifi extended?
