It worked with the pre-installed Ubuntu, but after re-installing Ubuntu dual-boot with Windows 8.1, the WiFi is not working.  Is there a driver for this adapter that will work on Ubuntu 12.04?

Just installed Ubuntu on new HP desktop "pavillion"all in one. Dual boot set up. I get the message no wifi adapter found when attempting to get online. What to do? Oh I do not know how to copy and paste my terminal info so it actually looks like it does on the terminal. (A little help with that would stop annoying people that are reading my questions.)  When I enter sudo lshw -C network I get:  *-network                  description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: enp1s0 version: 15 serial: c8:d9:d2:7b:00:b3 size: 1Gbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl8168h-2_0.0.2 02/26/15 ip=10.0.0.223 latency=0 link=yes multicast=yes port=MII speed=1Gbit/s resources: irq:49 ioport:f000(size=256) memory:fea04000-fea04fff memory:fea00000-fea03fff *-network UNCLAIMED description: Network controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: ioport:e000(size=256) memory:fe900000-fe90ffff   So I followed the already answered question advice of making sure I had the correct kernel which is currently 4.15 and I have the most updated rtl8822befw.bin firmware installed and I still am getting the no wifi adapter prompt.

I bought an AZTECH WL562USB wireless adapter and am stuck trying to install the driver.   The driver file I downloaded is a BZ2, called   2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO.bz2  How can I install the driver from this bz2 file?

--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 recently updated my Lenovo Y50 computer to 16.04. Since the update, I have been unable to see or connect to any wireless networks. The output of running sudo lshw -C network is:     *-network UNCLAIMED          description: Network controller          product: BCM4352 802.11ac Wireless Network Adapter          vendor: Broadcom Corporation          physical id: 0          bus info: pci@0000:08:00.0          version: 03          width: 64 bits          clock: 33MHz          capabilities: pm msi pciexpress cap_list          configuration: latency=0          resources: memory:d1600000-d1607fff memory:d1400000-d15fffff   The fact that the wireless network controller is unclaimed leads me to believe that this is a driver related issue.

I just installed Ubuntu on my laptop with a RTL8723BE adapter and the Wi-Fi is really spotty.  Sometimes available wireless networks won't even show up in the menu, and other times just the network in my household will show up and just barely function (I can ping, sites like Stack Exchange usually manage to load, etc.)  I saw online some people suggest in a terminal entering echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf and rebooting, but it didn't work.  I saw someone suggest updating the driver with:  sudo apt-get install build-essential git git clone https://github.com/lwfinger/rtlwifi_new/ cd rtlwifi_new make sudo make install sudo modprobe -r rtl8723be sudo modprobe rtl8723be   Rebooted, and it still didn't work.  I also found this, and it didn't work:  sudo add-apt-repository ppa:hanipouspilot/rtlwifi  sudo apt-get update  sudo apt-get install rtlwifi-new-dkms linux-firmware   I have no problems with Windows on this laptop. Do I just have to accept I can't use Ubuntu on it?

When I ordered this TP-Link AC1300 Wireless Dual Band PCI-Express Adapter (Archer T6E), I looked into customers reviews and they said it worked fine with no drivers on Ubuntu. I didn't have a CD/DVD player on my desktop so I (on a laptop with a DVD drive) copied and pasted the DVD support disk content on to a USB drive and used that. But when I tried to run autorun.exe it puts up archive manager and says An error occurred while loading the archive Ubuntu verison- Ubuntu 16.04 LTS.

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'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 have purchased a TP-LINK TL-WN823N (EU) V2.0 device, which is a USB device that should work as a Network Interface Card, allowing me to connect my computer to wireless networks. Unfortunately, I am unable to find any wireless networks using this device using either wicd or network-manager (no networks appear in the list of networks supplied by either application).  A CD came with the device claiming "Linux support". The CD contained a URL to a corrupted archive file for downloading installation resources. I try to mask my immense frustration.  Here is the additional dmesg output I receive when I connect the device to my computer (similar content is present when I boot the computer with the device connected):  [17096.009912] usb 2-1.2: new high-speed USB device number 4 using ehci-pci [17096.103501] usb 2-1.2: New USB device found, idVendor=2357, idProduct=0109 [17096.103513] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [17096.103527] usb 2-1.2: Product: 802.11n NIC [17096.103529] usb 2-1.2: Manufacturer: Realtek [17096.103530] usb 2-1.2: SerialNumber: 00e04c000001   This is my lsusb, where the offending device corresponds to Bus 002 Device 004:  Bus 002 Device 003: ID 0a5c:5800 Broadcom Corp.

My questions are:   Why are no networks present in the list for wicd or network-manager? Why is there no additional network interface created when I plug in the USB device? Is it possible to create this network interface?   Thanks for reading.
