On May 27 and 28, the router would go offline periodically, and not be pingable from the local network at address 192.168.0.5 (cbr400). From the web interface (http://cbr400
), System Settings -> System Control -> Advanced, I turned off "Enable Watchdog Reboot" to see if that would help. The CBR400 stayed up all night. When we arrived at the trailer (9:20) it was pingable, but the web interface would not respond.

The cellular worked quite well yesterday, but not so hot today, frequent disconnects. I tried enabling the watchdog reset on the CBR but then disabled it again after several hours since it didn't help. The router_check.sh script on the "high" dsm is our own watchdog reset.
While on the tower, I checked the antenna cable connections at the modems, and the usb connections at the hug. All looked good.
TODO: look at the logs. Perhaps the signal levels were lower today? Contact verizon about 4G.
