Im just wondering if theres anyone willing to look through the log files to see if they can locate the issue as ive had a look but dont seem to know where to start. logs

Change the cabling or at least reseat it at both the server and switch / router (and power cycling is also a good idea for server and router/switch)
September 11, 2025Sep 11 Community Expert it is worth pointing out that the commonest cause for a LAN link downgrading to 100 Mbps is not all 4 twisted pairs in the cable making an end-to-end link. The 100 Mbps link only requires 2 of the twisted pairs to be working. Can be the cable itself, or something like a pin on a port is plugged into not making proper contact.
