When ISP drops connection, so does my wireless connectivity

I am not sure where the disconnect is here with my wireless setup, but any time that my ISP drops connectivity (cable modem is still on but no connectivity, thanks Cox), my internal wireless connectivity does as well and does not return until I get ISP connectivity returned. Wired clients stay connected to my internal network, but wireless APs are no longer accessible.

I don't have anything elaborate set up with wireless other than this new MESH network that doesn't work well at all (lot of errors in the log related to the new AP - separate post incoming on that).

APs are Sophos brand

Bridged to AP LAN

Standard security (WPA2 Personal)

What am I missing?

Thanks.

Are the AP's somehow cloud controlled? No cloud, no work?

What happens if you just unplug the ethernet cable from the modem, AP's still connected?

So, I just physically unplugged my cable modem from UTM, and my wireless stayed up and I was able to browse my internal network. Even tried to get online with a wireless device and it showed I had no internet connectivity.

But if the cable modem detects an ISP outage, it drops my wireless connectivity altogether.

What happens if you turn off power to the modem?

I would think that would operate the same way as me unplugging the modem from the back of my UTM, but I will try that after the wife is done working. I was going to do that after, but she needed connectivity again. :)

That's a crazy interaction between the isp going offline and utm.

Do you have another router you can put in between the modem and utm as a means of isolating the utm?

The expected behavior is isp goes offline but the rest of your lan and wirelesslan continue working.
