Configure ALFA R36 / R36A with Tube-2H / Tube-2HP

First, please connect the Tube-2H via network cable to the port labeled "PoE" on the PoE injector. Then, connect a computer/laptop/netbook via network cable to the "LAN" port.
Do not connect the Tube to a router or switch in the network; instead, connect it directly to the network port of a computer.

Now, enter 192.168.2.1 in your browser, and you should see the following window.

If you see the interface of your router (Speedport, Easybox, etc.), please disconnect the computer's WiFi connection to the router until the Tube configuration is complete.
(If two devices in the network use the same IP address, issues may arise.)
