These adapters do what they should, and without flaws. Allen, who discover here that the adapter will not work, must be said that one should be aware of course the purpose of these parts: They are in no way to turn a router port two! Its sole purpose is an existing Cat-5e to better use (O.-6) cabling. Building on the insight that a 10 / 100Mbps network port requires only 4 wires, you can use 4 cores of the same cable intelligent "rest" with these adapters the rest. For this purpose, you have to insert the adapter always pairs (in some places they are not sold separately), it is available in the variants Network / Network, network / ISDN and ISDN / ISDN. Accordingly, the pin assignment of the RJ-45 jacks 1236/1236 or 1236/3456 or 3456/3456. One must therefore be clear before buying about which services you want to switch. If you want to operate on the cable gigabit network and PoE, the parts do not work, because for more than 4 cores of the network cable are required. You need at his DSL modem or router more network ports, you have to fall back on even a switch.
