SOLVED problems enabling wifi on Compaq Mini 110

Post by fraxinus_63 » Tue Jun 02, 2015 11:34 am

I have acquired a little HP Compaq Mini 110 netbook and am running Mint 17.1 XFCE on it, freshly installed and fully updated.

I'm very pleased with its performance. But I cannot get it to detect or connect to any wifi network. The wireless card is a Broadcom BCM4312 802.11b/g LP-PHY.

I am getting tired now (fortunately I am not losing my temper!) but I have been up and down the thread at http://forums.linuxmint.com/viewtopic.php?f=53&t=131910 for hours and have not yet found a solution that work for me. It is so frustrating as my wife and I are genuinely delighted with how Mint runs on this device in all other respects.

One obvious question - if I eventually fail to get the onboard wifi to work, might I be better off buying a USB wifi dongle and having a go at configuring that? I know this is a bit of a newbie question but is there any reason why this might not work? I could easily spare a USB port for such a device.

Many thanks in anticipation if anyone can advise me.

Try this:

(item 1.2, left column)

If the bcmwl-kernel-source driver doesn't work, before trying the b43, post the outcome of this command:

Code: Select all

sudo rfkill list all

Thanks very much Pjotr!

I have worked my way through the suggestions at https://sites.google.com/site/easylinux ... her-driver, but nothing has worked yet despite very many tinkerings and reboots.

The XFCE Driver Manager seems to identify the Broadcom card all right and tells me that bcmwl-kernel-source is installed and in use.

The Wicd Network Manager applet only ever tells me that no wireless networks are found.

I can find no indication in BIOS that the Broadcom card is switched off.

Code: Select all

sudo rfkill list all
Output - nil. Does this tell you anything??

if I type

Code: Select all

iwconfig
output is "no wireless extensions" for lo and eth0.

I have not yet tried the b43.

I also tried

Code: Select all

sudo lshw -class network
.

Output:

Code: Select all

*-network

       resources: irq:43 memory:febc0000-febfffff ioport:ec80(size=128)
This would seem to indicate that the Broadcom card is present and switched on. Does the entry under "configuration" suggest that it is seeking the b43 driver?

I'm at a loss, I'm afraid.... :(

I advise to contact one of the Wifi guru's on this forum, like JeremyB:

I will certainly contact the person you suggested.

As a fall back - if I cannot get the onboard wifi to work - would it be worth me buying a USB wireless card or dongle that would do the job for me? I know nothing at all about these devices or their Linux drivers. However, if feasible it might be more time- and cost-effective for me to do this than spend hours more troubleshooting!

Appreciate your help - thanks again.

This wireless dongle should work out of the box:
http://www.amazon.com/TP-LINK-TL-WN725N ... B008IFXQFU

Plug it in and it works. There's only one harmless visual bug: all wireless networks that it detects, *seem* to have a signal strength of 0. But that's not the case; you should be able to connect with your wireless network without problems.

Another noteworthy thing: when in use, the LED light on the adapter is constantly blinking; this reflects the data transport that's taking place.

The driver manager might be telling you that bcmwl(broadcom STA) driver is being used but your lshw output shows b43 is in use, so try

Code: Select all

sudo apt-get purge bcmwl-kernel-source

Code: Select all

sudo apt-get install firmware-b43-installer
and reboot

Thanks both of you for advice.

I'm away now for a couple of days but I will try this fix at the weekend and will let you know how it goes.

Hi all,

This is my first post here on the Linux Mint forum. I'm a newbie.
I've had the exact same problem on my Compaq Mini CQ10 for the last six months. I am running Mint 17 Mate.
Oh how I have been waiting for this thread to show up! :-)

JeremyB - You are the man!!
I followed your instructions and installed the driver(s) you recommended and it works flawlessly!

Fraxinus_63, I hope you follow this GREAT ADVICE from JeremyB as I am confident it will work for you also.
My reports were almost exactly the same as the ones you posted.

Thanks again JeremyB!

YES. IT WORKS FOR ME TOO!

Please forgive my shouting but JeremyB's commands have worked and I am a very happy man.

Thanks to both JeremyB (for providing the solution) and Pjotr (without whose encouragement I would have given up a week ago). If either of you are ever visiting beautiful Norfolk, in Eastern England, the beers or coffees are on me.
