How do I tell Ubuntu that I have an 802.11 wireless usb network adapter plugged into the computer?

First check that it sees it.
Code:
@biker:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 0bda:8189 Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter
Bus 002 Device 002: ID 058f:9360 Alcor Micro Corp. 8-in-1 Media Card Reader
Then see if you got a signal in Ubuntu the command is
I am in AntiX (which does not use sudo)
Code:
# ifconfig -a

wlan0 is my usb wireless interface. It shows that it is working also. Network manager in Ubuntu should be able to connect if these readings are right like mine, (filter done by me). I use wicd in AntiX for my home wireless wpa2 connection.
