Connecting ADSL modem

[made_in_YU]

Hello, tom'sHARDWARE. I'm trying to setup a wireless network at my home. I have no experience doing this, and very little experience with modems and routers. What I do have is couple of pictures to show you what am I trying to connect. Could you tell me if this is possible? And if it is how can I do it?

Picture 1: The little thingy that enables me to have internet on my computer (ISP's wireless adapter)

Picture 2: The other thing I'm trying to connect so that I can use wireless connection on my phone (Huawei EchoLife HG520b ADSL router)

If this Huawei box is ADLS router (with RJ11 phone jack), you cannot use it for whole house internet.

You need just "router" - a device which has WAN Ethernet port (where you will plug your thingy), and one or more LAN ethernet ports (ehere you will plug your computer), and optionally WiFi (for your phone).
