Hello,

I'm a newbie to Linux but I managed to install Ubuntu 12.04 on an old Desktop Presario. Since there was no wireless card, I bought a wireless USB adapter (Mini USB 2.0 / 1.1 Wireless WiFi N LAN Adapter IEEE 802.11n 802.11g 802.11b - 943MiUSBMiF320).

The dealer said that the adapter is compatible with Linux.

I was not able to install the software from the CD (maybe the file is .exe?), but from what I ascertained, the driver that needs to be installed is the Realtek RTL8188CUS.

As soon as I plug in the wireless adapter, the computer is able to detect wireless signals, but it cannot connect to them. When I go to network settings and try to establish a connection to my WiFi, the computer does not respond.

Can anyone help?
