    Re: Anybody with Ethernet knowledge?

    You're right. My bad.

      Re: Anybody with Ethernet knowledge?



      Well anyway, is there some simple way how to measure packetloss from unmanaged switch to slightly-managed NAS to reliably discover whether it works after it succeeds in negotiating GbE?

          If you get another PC on that network in addition to pinging you could try a packet analyzer like Wireshark.

            Pinging was OK but these packets are sometimes able to go through where TCP/IP are not - I have seen that. So that may not be so telling.

                Correcting the older slow Ethernet standards:
                10 base 2 and 10 base 5: requires 1 wire plus shield (2 conductors, half duplex by definition)
                10 base T: requires 2 twisted pairs (4 wires, duplexing by protocol, but 1 rx and 1 tx pair)

                Remember that 10baseT also required crossovers to connect two computers together without a hub/switch, granted modern machines did auto II/X negotiation.

                  Crossover works even now, it should be used between two computers but as most of them can do auto negotiation, it is not needed. But it's safer, auto does not always work.

                      I'm assuming (sometimes dangerous) that you want all the machines to be on the same network. If that is the case, it might be a better solution to only have one router assigning the addresses and opt for changing the other routers to act as switches. This would entail turning off DHCP in all the routers except the initial one, at the network source.

                        DHCP and NAT, than you can use all 5 connectors. If you leave NAT than you can only use those four which are switching.
