      Sure your cable is passing all 4 pairs?

          100 will work with just 1,2,3,6.  1000 requires all 8 conductors to be proper.

          Try another cable?  Or trot down to home depot and get a tester?

          At work I have a nice Fluke.  Here at home I have a Klein I got in a rush at home depot because I was tired of guessing.

            Just a little quirk of Gbit that I found the other day, might be useful to some reader some day. I had an old-old cable that someone has made themselves with just 4 wires connected. I had plugged it between my (now-modern) laptop with Gbit and a VLAN switch with Gbit. Lights came on at both ends and the devices thought they could do Gbit. The 2 Gbit devices seemed to negotiate Gbit with each other using the 4 wires.
            But of course traffic did not flow - the actual traffic is multiplexed on all 8 wires.

            So it is possible to have a cable with 1,2,3,6 pins good and some or all of the others bad and get Gbit negotiation. It can be a bit tricky to then diagnose why traffic does not flow.

            As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

              When I see a cable with just two pairs I cut it in half and throw it away.

              Strange you would get gig-e negotiation without all 8.  I've never seen that.  Troubleshot a 100-should-be-1000 negotiation the other day and found a patch cable with one of the brown wires faulty.  New patch cable = gig-e.

                Yes that's a common issue if you have old cables. Can be confusing if you're not aware of it. The initial negotiation takes place over 2 pairs. Many gigabit NICs have features to detect and negate the issue but many cheaper one don't.  ::) 'ethernet@wirespeed' is Broadcoms implementation for example.

                This has bitten me a number of times now, so I'm ready for it. :)

                      They could still be bad. Try swapping them. Try swapping switch ports. Try reassigning the LAN and WAN assignments. Try removing the switch completely, as a test just connect a single client directly.

                        sorry went on holiday and busy. the issue was the first switch, it is a fast Ethernet, i switched the switches. I now have full gigabit on both wan and lan. thank you guys for putting up with my ignorance, I greatly appreciate you guys being fast on your responses and taking the time to help me out.
