I opened xdiganose and it told me to go to  in order to download and install the wireless driver. I followed the instructions for Ubuntu and it aborted the installation saying something about an unsupported device (I should've saved the output, I'm using a late 2011 13" Macbook Pro.) Now when I try sudo apt-get install firmware-b43-installer I get this:  Reading package lists... Done Building dependency tree        Reading state information...

I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible.   What are the steps to install Broadcom wireless drivers for a BCM43xx card?  I'm a user with no advance knowledge in Linux, so I would need clear explanations on how to make, compile, etc.    lspci -vnn | grep Network showed:   Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b]      iwconfig showed:  lo        no wireless extensions. eth0      no wireless extensions.   NOTE: Answer below is updated every time new information is added and confirmed working.

I bought the wireless adapter to use with a computer without internet access but I can't figure out how to install it with just a USB with the driver on it. I've read a few articles on how to install the driver but they all require me to have internet access and I don't have internet. I'm completely new to Ubuntu. If you can help that would be great. Thanks!  Ps: I have the latest version of Ubuntu as of 7-5-16.

I am trying to install the USB wifi adapter: tp-link TL-WN821N V5.  I found a  for the V5 version but it won't compile.

I recently installed Ubuntu 14.04 on my Dell XPS 15 9530.  Now, everything except the wireless connection works fine. I've googled, and found  solution, but it didn't change anything for me (i.e. I added "options iwlwifi 11n_disable=1" to "/etc/modprobe.d/iwlwifi.conf").  I'm not sure what next steps I should take to solve this problem. I've read somewhere that updating the kernel might help I ran the command "uname -r" and got "3.13.0-24-generic" back, which implies i have the kernel version 3.13 and not the newest 3.18 according to .  If anyone has an idea what to try next or can point me somewhere, that would be awesome.

On Ubuntu 14.04.5 I just upgraded firefox to version 50.0; now there is a message on some pages which reads:   libavcodec may be vulnerable or is not supported, and should be updated to play videos   So how can I update libavcodec?  A simple   sudo apt-get install libavcodec   gives the following output:  Reading package lists... Done Building dependency tree        Reading state information... Done E: Unable to locate package libavcodec   So maybe I don't have libavcodec installed in the first place? So why do I get this message...?

Can someone help me with this problem ? I am new to Linux, so I do not know commands and I never did something like installing or compiling with command-line.  I bought WiFi adapter from Edimax, model EW-7811UN for my PC (not laptop, so I do not have wifi card, only ethernet). When I go through guide on CD, I came across a version of kernel. It said I need version 2.6, but I have 3.5.0-22-generic.   I got errors like I do not have file or folder etc. Can someone tell me where I can download compiled driver and where I need to put it? Or some other advice. I don't want downgrade kernel when it is not necessary.

I've never supported Apple in any way, but I like their hardware. As I've just purchased and got working a nice Apple wireless keyboard (bought second-hand!), I'm curious about the possibility of buying a second-hand MacBook and installing Ubuntu on it.   What, of what's important, isn't working? Notably, I do Flash Player development from time to time, so I do at the very least need to get a 32-bit debug player installed. (I usually run 64-bit, so I'm familiar with having to tweak things to get it all working properly) I'd also need to be able to play DVDs with CSS, run Google Chrome, etc. Is it fairly similar in capabilities as a non-Apple computer as far as what I can use? It seems that there's a different architecture used, namely PowerPC, and I don't know what this means to me as an end-user.   Can anyone recommend me for or against installing Ubuntu on MacBookPro?

Hi I am new to Ubuntu and Linux. As I am developing a WiFi product, I want to capture the WiFi traffic wirelessly with Wireshark. Having some searching in the web, I know that I can do that with a USB WiFi adapter and Ubuntu. Then I can run the Wireshark in real monitor/promiscuous mode.  Ok so I bought a TP-Link TP-WN722NC (I want to buy the TP-WN722N at first, but the store only has this model). Also I found a laptop and installed the Ubuntu 14.04.1. Then I noticed that I need a driver for this adaptor. So I try to follow the blog post  to install the driver ath9k_htc but seems it was not successful.  Then I downloaded the backports 3.16-1 by running these two commands:  wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.16/backports-3.16-1.tar.gz tar xvf compat-wireless-2.6.38.2-2.tar.bz2   However, after that point do not know what should I do. Could you help guide me to install the correct driver?

I have installed Debian 8/Jessie minimal ISO on my laptop. I get error message during system installation:  Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media, such as a USB stick or floppy. The missing firmware files are: iwlwifi-7265-9.ucode iwlwifi-7265-8.ucode If you have media available now, insert it, and continue. Load missing firmware from removable media?  I found the appropriate firmware on Debian website, downloaded it (zip), extracted to flash drive, and booted with flash drive plugged in. I still get the error message that appropriate firmware could not be found (the error message disappear to fast to copy down). How do I properly format the flash drive? Or is the problem here something else? Windows Explorer on another computer tells me the flash drive is 14.6GB and formatted as FAT32.
