      Make sure you understand how the leds work. I had two different switches; on one the green meant 1000 and yellow meant 100, and on the other it was reversed…  ::)

        2 of Intel PWLA8391GT PRO/1000 GT PCI Network Adapter in a dell dimension 4600
        possible the cable modem is shows the link led as yellow instead of green and so is the downstream led (i called about this and my isp has know idea why its like this) and my on of the wifi router it doesnt like to go through the thin wall

            So the pfSense status page agrees with the leds on the NIC?

                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.
