Laptop Wireless Card giving problems

Post by trope » Fri Sep 04, 2015 3:11 pm

I am using linux mint 17.1 (rebecca) on a dell latitude e6410. I have been having increasing problems connecting to Wifi, frequently after the computer suspends the Wifi does not work, disabling and reenabling it sometimes works and sometimes does not, but yesterday I was unable to connect to the internet at all after starting my computer. It would show the network name and % strength in the bottom right corner, but I could not load any pages. I know that the Wifi was working fine because I could access it on another device. I tried rebooting the computer and connecting to and disconnecting the Wifi in the bottom right corner and it did not work. Today it works fine, I don't know why it didn't work yesterday.

I would like to do whatever it takes to solve this problem so I have reliable access to Wifi, but I don't know if it is a driver/software problem or a hardware problem and if I should buy a new wireless card. How do I figure this out? If I would buy something, does it have to be compatible both with my current laptop as well as mint and how do I find out what would be compatible with BOTH?



I ran the command mentioned in the sticky and get:

If the problem would be the driver try to use opensource (b43) driver for your wireless card;

https://wireless.wiki.kernel.org/en/users/drivers/b43

You need to plug a network cable

Code: Select all

sudo apt-get install b43-fwcutter firmware-b43-installer
I suppose you're using the proprietary driver wl, to avoid loading the driver wl in the future, you need to blacklist it,

Code: Select all

sudo su (and then your password)
And then,

Code: Select all

echo "blacklist wl" >> /etc/modprobe.d/blacklist.conf
Restart your system.

Thanks. How can I tell what driver I'm using, was it displayed somewhere above in what I posted? And what do you mean that I need to "plug a network cable," are you saying that to do the steps you have described I should have a wired connection to the Internet?

Since you have internet access on at least one computer, download http://security.ubuntu.com/ubuntu/pool/ ... 15_all.deb and copy it to a USB drive/CD/DVD and get it on the Linux Mint computer, then double click on it and install, then in terminal

Code: Select all

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-dkms
Reboot and see if wifi works

Thanks for all of the suggestions. Some more output from running commands:

Code: Select all

lsmod | grep -e wl -e brcmsmac -e b43
brcmsmac              563041  0 
cordic                 12574  1 brcmsmac
brcmutil               15618  1 brcmsmac
b43                   387371  0

bcma                   52096  3 b43,brcmsmac
Which I think means that I am already using the b43 driver? Output from the other command:

Code: Select all

inxi -Nx
Network:   Card-1: Broadcom BCM43224 802.11a/b/g/n driver: bcma-pci-bridge bus-ID: 03:00.0

I tried to download it and install but get the error message:

Did I try to download it too late, is it out of date?

Select a mirror site from http://packages.ubuntu.com/utopic-updat ... e/download to download it from

If it doesn't work after installing the firmware and rebooting, do

Code: Select all

echo "blacklist b43" | sudo tee /etc/modprobe.d/broadcomb43.conf

Code: Select all

echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/broadcomb43.conf
Reboot

Thanks for the help. I tried downloading it from the link but received the error message:

two or more packages specified (linux-firmware utopic-updates)

Maybe I can do a search on that webiste to find the package? What package should I be searching for?


Update:
I bought and tried a new Wifi card but still had the same problem. I removed it and put back the old card and it seems to work more often (this is anecdotal), but still sometimes does not connect which is very problematic.

Downloaded the file, tried to install it and received the same error message as above:

Error: no longer provides linux-firmware


This was using the linux mint package installer but I suppose I would get the same message if using the terminal.

Can I assume that it installed, is there a command to check for it?

Edit: did a search online and this is the only other post I could find with the error message that I received:
http://forums.linuxmint.com/viewtopic.p ... 6&p=947140

Don't know if that applies to me, however, I have no problems with my media player.

We will do it via terminal

Code: Select all

dpkg -x Downloads/linux-firmware_1.143.4_all.deb ~/Desktop/firmware/
cd Desktop/firmware/
sudo cp lib/firmware/brcm/ /lib/firmware/
Reboot

This is what happened when I tried it in the terminal:

Code: Select all

$ dpkg -x Downloads/linux-firmware_1.143.4_all.deb ~/Desktop/firmware/
dpkg-deb: error: failed to read archive `Downloads/linux-firmware_1.143.4_all.deb': No such file or directory

However, I am not sure that the file is the problem and that it will install differently from the terminal, I was able to download it from your previous link but when I try to install it using the linux mint package installer I got the error message
Error: no longer provides linux-firmware

Maybe there is some problem with my system that this package will not install? I looked again at the link I posted where someone else had this error message come up but it does not look like he was able to resolve it.

It gave me that same error but I could copy the firmware files manually, your file must not have saved to Downloads

We can check to see if the firmware files already exist with

Code: Select all

ls -l /lib/firmware/brcm/ | grep bcm

Output from the last command:

-rw-r--r-- 1 root root 96224 Mar 2 2014 bcm43xx-0.fw
-rw-r--r-- 1 root root 180 Mar 2 2014 bcm43xx_hdr-0.fw


I had been trying to run the file directly from downloading, am trying to save it to Downloads and run it now.

Ok, I got the 3 commands above to work, I had to change the last one to:

Code: Select all

sudo cp -r lib/firmware/brcm/ /lib/firmware/
I re-ran the other command:

ls -l /lib/firmware/brcm/ | grep bcm
-rw-r--r-- 1 root root 269595 Nov 10 14:24 bcm4329-fullmac-4.bin
-rw-r--r-- 1 root root 96224 Nov 10 14:24 bcm43xx-0.fw
-rw-r--r-- 1 root root 180 Nov 10 14:24 bcm43xx_hdr-0.fw

It shows the dates as updated but the files appear the same. Does it mean I already had the right firmware?

Thanks for all your help by the way, I am looking forward to getting this resolved as soon as possible.

Since the firmware is there, I will have you run the wireless script from ubuntuforums

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
Then paste the contents of the wireless-info.txt file in a post

When the internal wireless card doesn't work, I have been using a usb wireless card (which occasionally also doesn't work, but most of the time does). Should I run these commands without the USB Wifi or with it, or does it not matter?

The command does not work when my internet doesn't work because the script is located on the internet. I tried downloading it to my downloads directory and saving it as "wireless-info" and running the command as follows, but it gives me an error message:

Code: Select all

   wget -N -t 5 -T 10 /max/downloads/wireless-info && chmod +x wireless-info && ./wireless-info
/max/downloads/wireless-info: Scheme missing.
Am I doing it wrong or did I not understand your instructions?
