Network LAN @ 100Mbps and not 1Gbps

[rigveda]

I was wondering why my file transfers were so slow and realised that my interface on my TNAS is reporting only 100Mbps and not 1Gbps. I am running a 1Gbps/ switch connecting to my PC which is also 1 Gbps Ethernet card.

I am running TOS 5.1.123

How do I configure it for a 1Gbps interface?

Check your cables as that is most likely where the problem is.
