why does iphone keep showing drive off line my passport is not accessible, it is connected to my wifi
Sounds like the Wi-Fi connection may not be staying connected to your iPhone or its experiencing interrupts. If you have the MPW connected to your Wi-Fi, I would check the router table to see if it’s still there or do a ping. If MPW is too far away, the signal may not be good.
