No networks show up in my HP Pavilion dv6000

I installed the firmware-b43-installer and purged bcmwl-kernel-source. I can the “enable wifi” in the network menu but I couldn’t see my home network shown. Can someone verify my wifi is working or not?

Looks like your Wireless interface is disabled.

Open a terminal and try running

ifup wlan0

Thank you very much for the response. I tried but:

[email protected]:~$ ifup wlan0
Unknown interface wlan0
[email protected]:~$

Reboot your machine. Just installing firmware-b43-installer and purging bcmwl-kernel-source won’t activate your wireless without a reboot. Good luck @chauncyliu.

done all these. wifi is still disabled :frowning:

Hmmm, I did it again from the beginning and it works now. Thanks
