Hi Randy

Not sure if it helps but once I had a similar issue where the probe was getting disconnected after every 4-5 days. I could see probe was reachable on the LAN and even had a smokeping instance pointed to it which was all clean. My own internet behind the same network was working fine. Eventually found that issue was with the Ubnt edgerouter which used tweaked VyOS and in their latest version 2.0.8 it was breaking the secondary routing tables running on the device after every 4-5 days of uptime. So except the main table, rest all tables were in config but just didn't show up in "show routing table X" output. Eventually downgraded the OS version and waiting for an update in next release notes of the firmware update.

status shows it down

but i can ping6 the probe, and from the local gateway, i can ping4
it's natted address

network tab shows a long history of very short disconnects

there is a strat 1 sitting on the same lan, and a lot of chimers out in
the world think the strat 1 is preferred. no, that is not a definitive
test in any way, but it's all i can think of at my current caffeine
level.

comcast? modem? v1 probe?

how to better diagnose?
