WiFi not available on Compaq 6720s with Mint 17.3

[atvasco]

I have installed Mint Cinnamon 17.3 on my Compaq 6720s laptop and have a dual boot with Windows-XP.
The Wifi under Windows-XP works fine but the WiFi indicator on the laptop does not illuminate under Mint.

The WiFi details are:
Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)


I've tried: sudo apt-get install firmware-b43-installer but this had no effect.

LAN connections work fine.

Can anybody help please?
Thanks

Do you have a wifi on/off button on the keyboard? ... an function button with Wifi or Travel (airplane) icon on it?

[atvasco]

Thanks JeremyB.
Here is the result:

alex@HP-6720s ~ $ cat /etc/modprobe.d/dkms.conf; cat /etc/modprobe.d/backports.conf
# modprobe information used for DKMS modules

# This is a stub file, should be edited when needed,
# used by default by DKMS.

Thanks for your suggestion.
In the second line of my original post I mentioned that the WiFi indicator did not illuminate to show that the wifi adapter was active, (the indicator will be BLUE to indicate wifi adapter is active and ORANGE to indicat wifi adapter is inactive).
On an HP 6720s the indicator is an integral part of a push-button switch that allows the user to switch on/off the wifi adapter.

It's the first thing that a user would check.

Thanks again for your help.

OK, I'm a fairly green Linux noob and sorta learning how to debug this stuff by following along with @jeremyB on some cases. Hopefully I help more than I confuse I did not see your output from his request for output from the command...

Code: Select all

rfkill list all

I was expecting to see something like this...

0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Hi bbaker6212,

Yes, I'm noob on linux too but I appreciate any help.

After trying all the stuff JeremyB suggested I had to do a cold re-boot, (rather than a suspend), the WiFi indicator lit up blue and I could connect via WiFi to my router. So now things seem to be working as they should.
Wierd...

For your info I ran the rfkill command and got this result:

alex@HP-6720s ~ $ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
alex@HP-6720s ~ $


Thanks all of you for your help.

If a cold boot was the solution it may have been firmware related
