Apr 17, 2014  Note. This Guide is for b43 and b43-legacy driver only, If you want to install the STA driver then follow my other guide on how to Install Broadcom STA wireless driver in Ubuntu 14.04 / 13.10 / 13.04 / 12.10 / 12.04. If the below driver doesn’t work then try STA driver.

Indeed it is a common issue not only with with network adapters but other network adapters as well in Ubuntu Linux.A relief is that Ubuntu provides additional drivers specifically for various wireless adapters. But the issue is that to you will need a network connection. If you have a wired connection, it will be very easy to install the additional drivers. But if you are restricted to the wireless network only, you’ll have to look for alternate methods.In this tutorial, I’ll show you a few methods to fix wifi issue in Ubuntu and other Ubuntu based distributions such as Linux Mint, elementary OS etc.

Hack squat vs leg press. It is easier to achieve that than with the squat due to the constant tension being placed on the muscle.

Fix no WiFi issue in Ubuntu based Linux distributionsFirst, find out the network adapter in your system. You can refer to this article to. In fact, you can just or not. If there are propriety drivers available, this method will easily work for you. Also, you will need the ISO image of the same Ubuntu version. Method 1: Use the ISO image to install additional wifi drivers in Ubuntu Step 1:Get the ISO image of Ubuntu. If you just had a fresh install, you must have this ISO image in some other system or same system in another OS in dual boot. Copy it to an external device such as USB or DVD.

Just copy it, don’t burn it as bootable USB.Now boot into Ubuntu and copy this Ubuntu ISO image to your home directory. It may happen that Ubuntu doesn’t show additional drivers for your system or you may not be able to install the additional driver. It could also be the case that despite the additional drivers installed, the wifi still doesn’t work.In that case, you may refer to the next method but keep in mind that it is exclusively for systems with Broadcom wireless adapters. Method 2: Fix no WiFi in Ubuntu with broadcom wireless adaptersThis method is exclusively for Broadcom 43 series of wireless adapters. So make sure that you have these adapters by using this command: sudo lshw -C networkIf you see a wireless network adapter starting with BCM43, then only you should go ahead with this part of the tutorial.-networkdescription: Wireless interfaceproduct: BCM4360 802.11ac Wireless Network Adaptervendor: Broadcom Corporationphysical id: 0bus info::03:00.0logical name: wlan0 Step 1:The first step is to remove any broadcom drivers already installed on your system.

Open a terminal and use the following command: sudo apt remove broadcom-sta-dkms bcmwl-kernel-source Step 2: If you are connected to internet via ethernetIf you are connected to internet via LAN/Ethernet cable, you can install different broadcom drivers using this command: sudo apt install firmware-b43-installerOnce the install is finished doing its work, you’ll need to reboot. After you log back in, you’ll be able to see and access your wifi connections. Step 2: If you don’t have any internet connectionsIf you don’t have ethernet, you may still be able to pull this off. But you’ll need another system with active internet connection.What you are going to do here is to download the driver manually and then transfer it to your problematic Linux system and install it there.First go to this link and click on the. Once installed, go to download folder and use the dpkg command to install the package from deb file. Cd /Downloadssudo dpkg -Ri firmware-b43-installer.Follow the rest of the instructions to install the drivers.

Once installed, reboot your system. You should have the WiFi now.Did it work for you?Troubleshooting wifi issue could be tricky in Linux. I have encountered an issue where Ubuntu could see the wireless networks but couldn’t connect to it.I hope this post helped you to fix no wireless network issue in聽Ubuntu. If you have questions or suggestions, feel free to drop a comment.

How to Enable Wi-Fi on MacBook, Mac Mini, MacBook Air for Ubuntu/Linux OSBy default older Mac computer models have driver issues with the Broadcom Wi-Fi chip. Most instructions online (such as this one from the official Ubuntu docs @ ) suggest to use sudo apt-get and install these packages from the PPA.BUT you don't have Internet so you can't use apt-get! Instead you can use a different computer to download the packages, then transfer them over.In the instructions below, you will need to replace sid in the download URL's with the proper version of Debian your version of Ubuntu/Linux is using. To find which version you should use, you can view the chart at.

If you're using jessie for example, then replace all sid with jessie in the links below. Download b43-fwcutter @ ( replace 'sid' in the URL as needed - scroll down to 'Download' section and choose based off your architecture, and then select a mirror/FTP link to download from on the next page that appears).

Download firmware-b43-installer @ (repeat same note as above). Download webfs @ (repeat same note as above). Download (e.g.

I created a GitHub account just now for the express purpose of returning here to say: holy crap, it worked! Thankyouthankyouthankyouinherited my mom's mid-2009 15' MB Pro when she passed a few years ago.

It's still a super beefy rig (4g dual core half gig storage - very well suited for creative content production), excepting of course for the Cupertino Colossus' insistence upon abandoning their own still-working hardware. I was determined to return it to a state of usefulness. Ubuntu was the obvious choice. I'd tried it several years ago and really liked it. (fwiw, non-tech me had ZERO problems setting it up as a dual-boot in the PC / Windows environment on a Dell I'd had at the time, although that ease probably had a lot to do with having had a cooperative CD burner at the time).Again - I am not a super tech-savvy guy.

Neither of our Apple 'super drives' (hows THAT for cynical branding, btw?) work reliably (i.e. No burn-to-DVD), so the OS installation itself required my patience and LOTS of persistence.And then I ran into the Broadcom / wifi issue. Good times hahahamore persistence applied.

But even though my deep dive into a discomfort zone found me working through these steps VERY slowly / cautiously, at the culmination of the last step, first attempt, the clouds parted, a chorus of angels began singing, and blink! - wifi visible and functional.Super relieved, and extremely grateful. I have what's functionally a brand new decade old laptop. And it's again a nimble screamer of a rig.

Thank you again!
