Do you have mac filtering enabled in your wireless router? If so does the list of accepted mac addresses include the one for your Compaq wireless card.

If you don't understand any of that last sentence, then the chances are that you do not have mac filtering enabled, it will never be enabled by default, you have to do it yourself, and if you have done it yourself, you would understand the sentence. Unless of course somebody else set up your router for you and didn't tell you what they had done?

This chipset should work out of the box, did you install the Broadcom drivers? Please supply the outputs of the following

Code: Select all

inxi -SNx
dmesg | egrep "wl |sta |wlan0"
