I have just installed ubuntu 14.04 and my wifi networks are not showing. I do not have the broadcom wifi driver in my settings and I've tried the mediatek wifi adapter, but I get "modprobe: ERROR: could not insert 'mt7630e': Required key not available" when i run the install command. Here are excerpts from when my wireless-info file  ##### rfkill ############################  0: asus-wlan: Wireless LAN     Soft blocked: no     Hard blocked: no 1: asus-bluetooth: Bluetooth     Soft blocked: no     Hard blocked: no   ##### NetworkManager.state ##############  [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true WimaxEnabled=true   Please help!

This issue happens only on UEFI systems with enabled Secure Boot.  When I try to install DKMS modules like VirtualBox, Nvidia, or Broadcom drivers, they do not install and I get Required key not available when I try to modprobe them.  VirtualBox complains that vboxdrv is not loaded.  Broadcom wl driver is shown in lspci -k as a kernel module but is not in use. sudo modprobe wl throws Required key not available.  Also this issue may happen when I install some kernel modules from git sources.  This issue may appear after a kernel update as disabled wireless adapter, black screen after a reboot, etc.   How can I fix it?

My wifi card is an Intel® Wireless-AX200 (802.11/a/b/g/n/ac/ax), Bluetooth® 5, and bluetooth is working. I've tried following various guides, however these drivers are apparently yet to make it into the kernel.  Their product brief states linux is supported:    And yet their driver page has no listing for them:    sudo lshw -c network =&gt; mark@m-blade-2019:~$ sudo lshw -c network   *-network UNCLAIMED               description: Network controller        product: Intel Corporation        vendor: Intel Corporation        physical id: 0        bus info: pci@0000:02:00.0        version: 1a        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress msix cap_list        configuration: latency=0        resources: memory:cf300000-cf303fff   *-network        description: Ethernet interface        physical id: 2        logical name: enx0050b6b47e72        serial: 00:50:b6:b4:7e:72        capabilities: ethernet physical        configuration: broadcast=yes driver=cdc_ncm driverversion=22-Aug-2005 firmware=CDC NCM ip=192.168.1.17 link=yes multicast=yes   I'm running kernel version Linux 5.0.0-13-generic, any help is greatly appreciated.

--Edit-- (in case I need to see this again)  After a clean install this worked: Your device uses the driver b43 and proprietary firmware. The Broadcom STA driver which provides wl is not appropriate. Please get a temporary wired ethernet connection and do:  sudo apt-get remove --purge bcmwl-kernel-source   If it isn't installed, just proceed.  sudo apt-get install linux-firmware-nonfree sudo modprobe -r b43 &amp;&amp; sudo modprobe b43   You should be all set.  --  Thank you guys!!   Tried using the Additional Drivers gui and that didn't work. Tried using jockey-text --list  kmod:wl - Broadcom STA proprietary wireless driver (Proprietary, Disabled, Not in use) [auto-install]   Tried using jockey-text --enable=kmod:wl this was the response  Sorry, the installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log   From the log file:  2013-02-09 00:49:57,904 DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: enabled, b43legacy: enabled 2013-02-09 00:50:05,572 WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl 2013-02-09 00:50:05,572 WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver 2013-02-09 00:50:05,600 DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: enabled, b43legacy: enabled    Now it looks and feels like I'm doing everything right and the similar searchs seemed to suggest doing what I've done, so what am I doing wrong and how does one enable this driver? second to last line of the log suggests the file or directory is missing, is there somewhere I can get a linux broadcom driver from to put in that directory? If it's missing why is it in the list?  Please help, while the graphics driver is only partially supported it has given me the right resolution, and everything runs without crashing (but the system information says it's an unknown graphics card, I can live with that) but without the wireless card working I have sit really close to the router thanks to a very short cable...

I did the following in a terminal to get a AC1200 Linksys Wireless adapter to work on my Ubuntu 19.10 install:  sudo apt-get install linux-headers-$(uname -r) linux-headers-generic build-essential git git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux cd rtl8812AU_8821AU_linux make sudo make install   This process went through without errors and install was completed.  However, my wireless USB adapter still doesn't work. I ran lsusb in terminal and my wireless adapter was listed as  Bus 002 Device 004: ID 13b1:003f Linksys WUSB6300 802.11a/b/g/n/ac Wireless Adapter [Realtek RTL8812AU]   I then ran the following, and it simply returned the command line prompt  modinfo 8812au | egrep -i 'versi|filen|003f' sudo modprobe -v 8812au iwconfig iwlist chan   When I opened my network setting for WiFi, I received the following:     No WiFi Adapter found   Make sure you have a wifi adapter plugged in and turned on   I also tried to get it to work by installing ndiswrapper, but that didn't work either.  I have researched this and have tried numerous things I found, but nothing seems to work. I know this has been answered before, but the answers all indicate the above procedure.  Any help is appreciated as I am new to Ubuntu, but have run Red Hat linux prior to its shifting to Fedora.

Now I am not sure what to try next. I am not Ubuntu expert, and would appreciate any help.  Thanks a lot in advance.

I want to create WiFi hotspot for android device using Broadcom BCM43142 chipset. OS : 14.0.4but I am stuck at a STEP which says your Wireless card should support AP mode!The current  driver: wl0 which I am using does not support AP(access point) mode.     iw list    Result :  Supported interface modes:        * IBSS        * managed   I found many drivers for other broadcom chipset like BCM4312 that support AP mode ex : b43 driver but failed to find for BCM43142.  Is their any driver available for Broadcom BCM43142 that support AP mode? OR  Is their any other way I can create hotspot for my android device using Broadcom BCM43142 card (os : Ubuntu 14.0.4)?  Thanks.

I upgraded Ubuntu from 11.10 to 12.04, until which wireless was working just fine. After the upgrade and reboot, wireless is not even being detected (When I click the network manager icon in the top panel, it does not show the wireless networks. Neither the Enable wireless option is there). But my laptop's LED indicator shows wireless is on.  This is a Dell Vostro 3450 laptop with:     Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)** (from lspci). Is any other info needed?   How do I get Wifi working?

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)

As requested , my wireless-info output is at .  I've tested Mint 19, Kubuntu and KDE neon, with similar results.  Is there an official driver that works out of the box?

I'm trying to connect my desktop (running 64-bit Ubuntu 12.04) to an Airport Extreme Base Station by using an ASUS USB-N13 wireless adapter.  I plugged it in, turned on the desktop, and the adapter was immediately recognized by the system. I found my home network listed in the available networks, typed my password (with the correct encryption) and hit connect. After that, the wireless icon just flashes (propagates? emits?) indefinitely, and every couple of minutes the "Wireless Authentication Required" box pops back up.   I don't know what to do. I've seen some solutions talking about an "rt2xxx" or "rt3xxx" driver or chipset. I don't know exactly what it is, but when I typed lsmod | grep rt I got:  parport_pc rtl8192cu rtl8192c_common rtlwifi mac80211 cfg80211 parport   I'm pretty much lost. Please AskUbuntu, what do?
