     305
     306Execute the command "sync", then reboot.  If there are no typos or discrepancies the interface "ppp0" should be available with a dhcp assigned address. 
     307
     308To troubleshoot check that the command below returns the correct device:
     309
     310{{{#!bash
     311echo /dev/$(for i in $(ls -d /sys/bus/usb/drivers/option/*/ttyUSB*); do basename $i; done | tail -n1)
     312}}}
     313
     314Note: name resolution will need to be configured.
