wvdial, USB dongle, and unexpected unplugging... - Raspberry Pi Forums
hi,
have pi2 sierra 3g usb dongle
can connect internet using dongle , wvdial
problem have unplugging usb dongle whilst has active data connection connected hangs entire pi - no local console, no networking, power cycle required bring life
if there no connection opened wvdial, unplugging / replugging not problem
of course dongle shouldn't unplugged whilst in use, ideally i'd handle situation better....
has else experience and/or have suggestion might help? have enabled hardware watchdog, workaround, bit messy...

you can try adding simple in crontab test if network responding , if it's not case .
if pi freezing, possibility reboot manually though.
code: select all
service networking restartif pi freezing, possibility reboot manually though.
