Tunnels Drop when WAN Links Go Down/Up

AllessioV

I keep having “flapping link” problems ever since I installed Fios 1 GiG Internet Service (about 2 weeks now since I signed up).

Since I work from home as a Network Engineer for a 5G company, these Vz problems have severely impacted my work.

A lot of my work involves setting up secure tunnels to remote labs & data centers. On a regular but non-deterministic basis, the tunnels drop and I can no longer do my work. This happens when the WAN links go down/up.

So this is a problem where the WAN link on the WiFi router bounces on a regular, non-deterministic basis and all the Vz support staff can do is recommend that I reboot the router, or, they run stupid continuity tests, which of course will pass for this type of problem.

In the mean time, I am now out of business, unable to do my work because a flap of the WAN link will most certainly occur within 10-20 minutes.

Could you try to change the cable between the ONT and the router?

Does the NTWK and MGMT light on ONT go out during the WAN link drop? Does the FAIL light come up during the WAN drop? If so, I can help you to check your PON line's power alarms.

Since you mention you are a network engineer, I think you should figure out the terms I used.
