USG1100 randomly rebooting

imaohw

I have a USG1100 running firmware version V4.73(AAPK.2). Recently it has started randomly rebooting every few weeks or so. What information should I capture to try and determine why it is rebooting?

In addition, when the USG1100 reboots its DHCP server does not hand out IP addresses. It seems like the DHCP server functionality is not running. Modifying the DHCP config on any ethernet or vlan config page will cause the USG to starting providing IP addresses.

Dust off insides of the unit. Try with a more recent power supply (a switching one with 50% more amperage shoult not be an issue).

Try latest 4.73 weekly.
