I have a Balance 20 with two WAN connections - both cable internet from the same provider. About weekly, one of the two drops out due to failing the DNS health check. I have swapped routers, cables, etc and the problem persists.
Balance 20 hardware revision 1
Running firmware **5.4.9 build 1732
**The only reliable fix is to reboot the Balance - works it every time for a couple of days.
I have tried changing to Google DNS for the health check - no improvement.
Changing to ping - no improvement.
Change to http lookup - no improvement.
Is there anything else you can suggest I try? Do I have a defective unit perhaps?
