This is my first time working with Ubuntu (or Linux), so please be patient.  I am running Ubuntu 12.04-powerpc "Precise Pangolin" on a Mac PowerBook G4 with 1.67GHz processor.  The firmware/driver for the wifi card is missing. For reasons not worth explaining, I cannot physically plug the computer into the network. I have another computer, a MacBook Pro running OSX, from which I can download files and port them by USB thumb drive.  The wifi card in the PowerBook G4 is by Broadcom. The chip is BCM4306, rev. 3. The PCI number is 14e4:4302.  I have downloaded b43-fwcutter_015-14_powerpc.deb and dropped it into the Home folder on the Ubuntu machine. However, it will not install. When I double-click, it opens with Ubuntu SoftwareCenter, but the "Install" button is inactive: I can't click it. There's a message beside the inactive button saying, "An older version of 'b43-fwcutter' is available in your normal software channels. Only install this file if you trust the origin." If I "right-click" the .deb file and open with Archive Manager, it shows me the "DEBIAN" and "usr" folders, but I'm unsure what to do from there...and fairly certain this is not the right way to do things.  Maybe I have the wrong version of b43-fwcutter for my machine/version of Ubuntu?  The documentation for this problem is a mess. It refers to all sorts of out-of-date Ubuntu versions and to an array of different "cutter" and firmware files. Maybe I'd be able to figure this out if I were a more seasoned Ubuntu user, but I have no idea why Sofware Center won't let me do the install. I would be VERY grateful for an explanation of how to get the wifi card working on this machine again. Thank you!

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.

I am having the same trouble as others getting my Atheros AR8131 Ethernet card recognised by Ubuntu 12.10 on my new HP Pavillion P7-1449 PC. I found the same question where the answer suggested the following:   Download Tarball compact-wireless-3.6.8-1-snpc Run  ./scripts/driver-select alx make sudo make install    The problem is when I run the make command I get the following:  make -C /lib/modules/3.5.0-21-generic/build M=/home/chris/Downloads/compat-wireless-3.6.8-1-snpc modules make: *** /lib/modules/3.5.0-21-generic/build: No such file or directory.

I have installed the new Ubuntu 14.10 on my Dell Inspiron 3521.  I was able to use my wifi in the Boot Live Stage and during the Installation phase by enabling the BroadCom BCM 43142 proprietary drivers.  But after installation I can't enable the proprietary drivers.  I can see the drivers listed there and when I select the option to use them and click Apply, the progress bar starts going ahead but stops in process and the 'Do not use them' option gets reselected.  I have searched some questions here according to which I must connect my laptop with an ethernet cable to get my wifi drivers working.  But I don't have any ethernet cable at present with me. I can only use the wifi on my second laptop.  Is there any other way to get the drivers working or Is there any offline installer like a .deb file for the drivers?  If anyone knows, please help!  I've reinstalled ubuntu thrice but the problem remains same.

When I installed ubuntu 18.04 on my HP Pavilion 15z 6 months ago, I had trouble getting the wifi driver to work. Installing the  solved my problem. 6 months later, I'm having trouble again with the "No wifi adapter found". I booted into my Windows 10 and the wifi works, so my wifi card is fine.   I uninstalled and reinstalled the rt18821ce from the kernel with no problems.  cd rtl8821ce/ sudo ./dkms-remove.sh sudo /dkms-install.sh   Then rebooted, but still no connection to wifi card.  Following the instructions on , I removed the rt18821ce and then installed official ubuntu package.  sudo dpkg -i rtl8821ce-dkms_5.2.5.2.1.30816.20190425-0ubuntu1_all.deb   Rebooted, still have the issue.

I just installed Solaris 11.3 on the laptop. This laptop have Broadcom BCM4312 WiFi card.  It looks like the install does not have a driver for this card just like 11.1 version.  I have a Linux installed on this same machine (Gentoo) and this OS does have a driver.  Is it possible to get the driver for this card somewhere? Maybe broadcom.com? Failing that is it possible to use Linux driver inside Solaris?  On the kind of related side - I tried to connect a wire and run Driver Manager, but it does not want to finish. All controls are  still disabled. Any idea?  Thank you for any pointers you can provide.

I purchased an HP laptop with the Qualcomm Atheros AR9565 (QCWB335) wireless adapter. I understand that this adapter is currently not supported on Ubuntu 12.04 and there is no way to get wireless access.  I installed compat-wireless-3.6.6-1 ath9k driver and it didn't work, lshw -C network still showed *-network UNCLAIMED after reset.  How can I figure out when Ubuntu will have driver for AR9565? Is there a workaround to get wireless working somehow?

I have a brand new Dell XPS 15. I   dual boot it with Windows 8.1 and  Ubuntu 14.10  The Wireless Network Adapter is Broadcom BCM4352 802.11ac with PCID [14e4:43b1] (rev 03).  The 4352 is not included in the list for installation via bcmwl-kernal-source file. I tried this anyway, but the Terminal command led to the file starting to install, but then stopping. Sometimes I get a permission denied error message.  As a result of reading and trying all advice from forums I have decided to completely reinstall Ubuntu 14.10. I doubt my particular Broadcom Wireless Card has no support on Ubuntu 14.10?    Edit:  The advice of Chili555 worked. I now have working wifi using Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03)

I could use my Broadcom wifi card just fine in the "try without installing" feature, but as soon as I installed it, it refused to use the card. I tried re-installing the drivers, but to no avail. ubuntu would start the process of using the card, but at around 75-85% it would just give up.
