Can't connect to internet alarm

[mezrich]

I have an a95 MFD running Lighthouse 19. I have a router on board that connects to the internet when I'm at a marina and the MFD connects to that router and then on to the internet.
When I pull away from the marina I get an alarm (dialog box) telling me I can no longer access the internet (which is true). I click OK, the alarm goes away but then in about 15 - 30 seconds it comes back. I can repeat this cycle (alarm, OK, no alarm, alarm) indefinitely.
Is there a way to disable that alarm (I don't see it in the alarm manager)?
I don't remember getting that alarm before I upgraded to Lighthouse 19...is that a new "feature"?
Excepting for disconnecting from the router, is there any other way to avoid this alarm?
