Broadband Dropping out - eth3.1 - WAN link DOWN.

[twistedmonkey]

I have Fibre broadband and every so often my WAN link drops (internet light orange), to bring it back I need to unplug and reconnect the uplink to the ONT, which restores service.

I would not mind, but it does NOT automatically reconnect. I either have to reboot my hub, or physically reconnect the ethernet port to the ONT. Using the webUI to disconnect and reconnect always fails to restore connectivity.

I've seen this at least 3 times so far since I was connected on the 3rd April, and for the last 3 I collected logs from the router, and in each case there was no error before the link going down. 

* 2024-04-22   10:21:51 syslog: [273968.949000] eth3 (Ext switch port: 4) (Logical Port: 12) Link DOWN.

* 2024-05-09   01:52:52 syslog: [687205.219000] eth3 (Ext switch port: 4) (Logical Port: 12) Link DOWN.

* 2024-05-30   20:59:42 syslog: [2570393.556000] eth3 (Ext switch port: 4) (Logical Port: 12) Link DOWN.

On the 22nd I restored service by rebooting, since then I have just disconnected the ethernet cable in port4 and service has come back.

Is there any fix for this?

@twistedmonkey   Please can you post your router stats so the forum can advise on any issues. This link explains how to do that https://helpforum.sky.com/t5/Broadband/How-to-find-your-Sky-Broadband-router-stats/td-p/2855717#

I doubt they will help that much. it just shows I'm using the WAN and LAN interfaces.

I shared them last night, and tonight but something seems to be deleting my reply (which is just a copy/paste of the stats.

Will try again.

@twistedmonkey you are right the stats dont show much but can I suggest you power down the hub for 30 to 45 minutes? This may help in two ways first the hub has been running for over a month and may have a minor issue due to a memory leak. The other reason with any luck that will switch the port on the server Sky are using for your connection which is a more likely cause. 

If that doesnt report the fault to Sky but I suspect they wont know what to do either. Best of luck.
