Wifi does not work on HP Pavillion dv7

Postby Acromarts on Mon Mar 11, 2013 8:36 am

Hello!

I have an HP Pavillion dv7 notebook that came with Windows Vista Home Premium 32-bit. it is about 3.5 years old.

I tried to use Linux Mint 14 using a boot-USB drive.
The problem is that my Wifi does not activate. When I use TAILS, the wifi does activate and I can select a network from the list, with Linux Mint and Ubuntu, this is not the case. I think that this is due to my wifi-switch being switched off, but I can't turn it on.

The Pavillion dv7 has a touchpad WiFi switch. I can only use that switch when Windows is fully booted. Windows automatically switches it off
(it turns from ON/blue to OFF/orange) when I shut down my computer or put it into sleep mode. Trying to push it when booted into Linux has no effect, it stays off.

I have tried the RfKill method ('sudo Rfkill unblock wifi' and 'sudo RfKill unblock all' But that doesn't seem to work.

I have tried to check my BIOS settings, but there are no power management options there that affect wifi. Could the 'Network Boot' be something I need? I tried to turn it on, but it didn't seem to have any effect.

I have tried to change the power management settings of the network adaptor through Windows (Properties, Power Management, uncheck 'allow windows to switch off this device to save energy')

I have not tried to connect my notebook to the router with a cable. I suspect that this would not cause problems?

Could it be that I need a driver?
If so, why does TAILS not make a problem of it and just work?
Could someone please help me to find the right driver? I find it difficult to find the right one.

The Network adaptors that are in my Device Management are:
- Broadcom 802.11g-netwerkadapter
- Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.0)

My router is a TP-Link router, it has a WPA2 Personal password.

I hope that I have supplied all the needed details :p. Does anyone know what the problem could be?

Linux Mint is funded by ads and donations.

Hello Acromarts and welcome to MINT,

Broadcom made two series of chips and they use different drivers;
Could you go to a terminal and type the following command and post the output here.
Code: Select all
lspci


in that list you should have the broadcom model number.
also in a terminal type this and post here
Code: Select all
rfkill list all

Sorry for the late response. I had to resolve a disk mounting issue first.

The lspci command gives a huge list, and these are the model numbers for the internet modules:
02:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)


Rfkill list all shows this, and only this:

0: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no

Ok you have the same Broadcom Card i Have and it is not block by any switch. So here is how to get it working. You will need a temporary Lan hard wire connection until you download and install the correct Drivers for your card The Broadcom 4312 card uses Broadcom-STA or WL Drivers. Not the
b43xx driver.

Here's the procedure to try first in Mint 14:

Additional drivers
To install additional drivers, please run the "Software Sources" tool from "Menu->Preferences->Software Sources" and click on the "Additional Drivers" tab. The tool used in previous versions of Linux Mint (Jockey) was discontinued upstream in Ubuntu.
you should be offered Broadcom-Sta driver try that method first. and let me know if it works

I am sending you this reply from a fully working Linux Mint-booted computer :). WiFi works like a charm!
The driver was easily found and installed using the method you described.

Many thanks!
