I have radio broadband via Virgin who uses the Optus network, This morning immediately on connection it hangs up. Below is the syslog entry for an attempt. Any one have any idea on why the (SIGHUP) appears at the end.... The system was rebooted same thing occurs, the old reliable phone line dialup still works though so the basic pppd operation and networking on the system works OK. Will a packet sniffer tell me anything. I am inclined to leave it till tomorrow to debug the issue as I have found this service is not the most reliable on the planet.
