I am using a 30m ethernet cat 5a cable from downstairs to upstairs. Downstairs is a TTB router connected to the phone via a Zyxel VMG-1312-B10A which connected to the phone. The VMG is connected to WAN port on the TTB router and the TTB router is connected on port 1 to a patch cable which is connected to a RJ45 socket which has the 30m ethernet cable punched in. Upstairs is an Asus RT-AC68U being used as as an access point again with socket and patch cable arrangement to the Asus WAN port.
My problem is that as far as I can remember I wired the RJ 45 sockets as all wires on the CAT5a are connected which should give me a 1000 BASE T connection between the TTB and Asus routers. For the immediate term this is not a problem as the fastest download I can get is 60mbps. The link is showing as 100 BASE T on the Asus.
If I ever get FTTP I would need the link to be 1000 BASE T to cope with over 100 mbps speeds. What have I done wrong, is there a difference in 100 BASE T and 1000 BASE T wiring? Why is the link negotiating 100mbps?
