Switch – Network adapter only works with ethernet switch

adapterethernetnetworkingswitchwindows-server-2003

I have a Dell XPS13(Win 10 Pro) and since we dont have wireless lan in the office i had to buy an external ethernet adapter (DA200).

The adapter works perfectly fine at home but it doesnt work at all in the office(not even the lights on the adapter are flashing) while i dont have any problems when connecting other computers to the ethernet socket.

However if i connect the adapter to an ethernet switch it works.

The laptop is part of a Win 2003 domain and on the server is a dhcp installed.

Is it possible that the adapter doesnt get an ip from the dhcp server?

Thanks in advance.

There is a chance that the network jack is wired wrong, and is acting as a crossover cable. Most modern NICs support auto MDIX, and can deal with this gracefully, but your dongle may not support this.

If you have a crossover network cable around, then put that in place between the dongle and the wall to see if that fixes it. If it does, you have wiring problems. If you do not have a crossover cable, then you'll need to verify that the terminations on both ends of the run are correct.
