Fios Internet dies repeatedly - log message is IGMP: join failure group

[richchocolate]

Hello, I am dealing with a frequent wifi issue.  A few times an hour, the internet connection will stop.

Log messages are below.  Any idea what is causing this?  Router is the G1100. I have an LTE Network extender that works like a local cell service, but when this glitch occurs it goes offline and takes 1 hr to reboot.  I have a lot of devices connected but no clue what IGMP is doing.

On the router, In the /mnt/log/local1 I see:

IGMP is for multicast, unlikely related to the intermittent connection.

If your wired Internet also intermittent?

Thanks for the reply.

I was on an old router with a 300bps plan.  I have since upgraded to the new tri-band router and 1gb plan and my connection is stable now.

I rarely believed a monolithic piece of device, such as a router, would die, but my G1100 died in the summer.

I guess the same might be applied to you, considering it is quite ancient at this point, released in 2015 I believe.
