Please tell us some basic information before asking for help:
Model Name: Asus Zenfone 9 8/256
Firmware Version: WW_32.2050.2050.29
Rooted or not: not rooted
Frequency of Occurrence: Once, but every time the computer / laptop is reset
I noticed that when I connect to the network on my computer / laptop using USB tethering, after about 30 minutes it becomes disconnected from it even though USB tethering is still active on the phone. When I repeat the action, i.e. disconnect the phone from the USB cable and plug it back in and turn on USB tethering, everything works normally until the computer / laptop is restarted. Then the situation I described at the beginning arises. Over and over again.
I note right away that this is not a problem with the computer / laptop or USB cable (original), because recently I tested it on my old Asus Zenfone 5 and the computer and the cable are working properly.
