This is occurring randomly but spaced apart at least 30 mins, from 6am to midnight. It's very strange. I've had fiber for a few years and its been solid as rock, and I've never had the fiber dropping before. The only issue I had before is the cat6 ethernet cable from router to ONT got twisted and would sync at 100mbit instead of 1000.

@jnaro  Here's hoping.

[Jayach]

I think this is the main place to disable IPv6, so that your devices aren't given an IPv6 address.

[jnaro]

yea I turned it off in there. 

[jnaro]

So its still disconnecting with all the IPv6 stuff turned off.

@jnaro One (or more) of your LAN connections have IPv6 turned on and are making requests. The "Link DOWN" bit is more interesting, can you get a bit more of the log and if possible format it as the way it's showing on the forum is using a lot of space, ta.

[Cynric]

@jnaro Just seen the 2nd bit. If there's a vacant LAN port can you swap your cables around? 

[jnaro]

Yeah. Gonna switch to another port.

[jnaro]

Switched LAN port on the router and switched to my other ethernet card on my PC. 

[Cynric]

@jnaro Change one thing at a time then test, otherwise you will not know for sure which adjustment made a difference.
