Hi,

I have a compaq presario v6000 laptop. I have installed ubuntu 10.04 on it. The wired network works fine but it does not recognize the wireless connection. Following are results of few commands which can be useful:

iwconfig :
lo no wireless extensions.

eth0 no wireless extensions.

pan0 no wireless extensions.

ifconfig:

I see an Ethernet controllor here: 00:14.0 Bridge: nVidia Corporation MCP51 Ethernet Controller (rev a3) but I don't see any wifi adapter.
What makes you think you have one?
ciao,
jdk

yeah cant see that but when i do lsusb i get this :

lsusb:

Bus 002 Device 002: ID 03f0:171d Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module]
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I am not sure but i think this is the wifi adapter

This looks like it. You'll have to see if it is supported and if you need special drivers/firmware for it. You have some googling to do.

Thanks for your help guys. I tried installing compat-wireless package after following the link provided by SalmonEater, but it didnt work. Will have to google more
