We have had fibre for a month now & have had this problem since day one. It was installed by Chorus with Slingshot as our isp. After many calls to SS they gave us a new modem but the problem has continued. It affects the desktop which is connected via an ethernet cable and our wireless devices simultaneously.
Oct 16 21:02:23 daemon, crit, kernel: eth0 (switch port: 4) Link DOWN.
Oct 16 21:02:27 daemon, crit, kernel: eth0 (switch port: 4) Link UP 1000 mbps full duplex.
I don't understand what the above means but when we have this problem this is what the system log says. Obviously this was only for 4 seconds but sometimes it'll run to minutes and can happen several times a day. I'm not sure SS understand what is happening as the advice I get from them is on how to change the wireless channel to see if speeds improve which isn't a problem as the speed is fine. Please is there anybody here who can enlighten me on what is happening so I can arm myself with more knowledge next time I talk to SS. TIA

When you tried the new modem did you swap out the Ethernet cable that connects to the ONT on the wall?

Sounds like a ONT firmware issue I heard about, Ask SS to log a job to Chorus to check this

of interest try locking the port speed to half duplex, GigE on the router.     ..... may be the port is auto negotiating for some weird reason????

Thanks for your reply. I'm afraid being a farmer the only part I understand is the part about contacting SS. I have though logged into my modem and can't find where I would lock the port speed to half duplex.

Sorry my bad, half is only available in 10 and 100.

 

Mind you i have not had the need to adjust those settings for some years now.

"Link down" isn't necessarily a physical layer issue it could be triggered at the MAC layer.
