I have a peplink balance 20firmeware 7.1.1 and 7.1.2 in a remote office and this unit was deployed over a year ago. For the past 5 weeks, almost every day, the connection either completely drops or degrades. We cannot get to the admin page either directly or through in control but the pep vpn tunnel appears to stay up (we can rdp into servers there). Users from within the office cannot access the internet or external resource by name or IP.
The issue happens daily for about 2 hour (10am-12pm) and then the problem resolves itself. If we reboot the balance 20 it fixes the problem.
Any ideas what could be going on?
