The problem I have is that the port on my laptop NIC is meant to have gigabit capability, but I am only connecting at 100.0Mbps and I don't know where the bottleneck is.
My Cat 5 ethernet cable connects my laptop to the RJ45 wall socket. The cable then runs through to a patch panel, which is connected to a gigabit unmanaged switch, which is in turn connected to a gigabit router and then off to the internet. When my adapater reports it's connection speed, which component is it reporting it's connection to? I would guess this is either the switch or the router but don't know for sure
