Ethernet Port producing collisions seen in Router statistics

[yngjedi]

My sky router is producing collision packets to the tune of about 300 b/s very 3 seconds seen by the router statistic page.  Unplug the ehternet port and collisions stop.  Collisions build up and I need to reboot the router, it clears the reporting stats (assume routing tables as well).  I have replaced the ethernet cables on both sides.  The ethernet port connects to a 48 port switch to run items in the house.  I also tried moving the ethernet cable port on the switch to a different switch port.  Same errors.

Unfortunately theres not a lot of info to go off here.

Have you tried with just a few devices connected to the switch to see if its possible that theres a device causing the collisions? Is it a managed or unmanaged switch? 

I think you need to work backwards and connect one device at a time to see if there is a single device causing the issue.

It's unmanaged. I'll try to clear out the switch and plug them in one at at time. Thanks

Strangely enough its the SKY Q box.  On hold with Sky now...

I've seen this happen before. Its related to the Sky Q box having multiple paths. Have you disabled WiFi on it?
