I've just installed Ubuntu on my Dell laptop, and the wireless is not working.  How could I fix it ? Is there any driver I should install?  Note: I'm also running windows 7 on the same laptop and the wireless connection works just fine.  Any suggestion would be helpful. Thanks!

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'm testing Ubuntu 18.04 with my current desktopand everything works correctly except for the Wi-Fi adapter. I'm using a TP-LINK TL-WN8200ND version 2.  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 have two laptops, both running Ubuntu 13.10, as well as a different OS (Windows 7), dual boot on both.  My wi-fi router is on my bedroom and I want to get the wi-fi signal from the living room. I can reach the wi-fi signal from both pcs when running windows, with a relative good signal, but can't reach it on both of them when running Ubuntu, can't even connect to it.  Is there something that I can do to amplify the wi-fi signal?

I just succesfully installed my printer driver. My printer is Brother MFC 255 CW. It works fine when I connected thorugh USB cable.  Then I tried to figure out how to connect using the wireless connection from the printer. Somehow ubuntu can't detect the printer signal.  This is so far the way what I did to try getting the printer connect to my laptop:   System setting Printer Add Printer Network Printer Appsocket/HP Jet Direct, then set the host with the IP address that the printer provided and port number: 9100 selecting the drive / installation after the additional installation finish I tried to print test page and nothing happen.   Is there any other way to figure out how to make the wireless working? Or maybe I did something wrong on the process...Please guys help me out......

I'm aware there's already been  regarding Nvidia drivers, but my case is a little different. My wireless adapter's driver is proprietary, and for a minimal install, I need a command to install it. A general command for any other restricted driver that I may come across in the future would also be extremely helpful.

I just installed Ubuntu 14.04.3 LTS after installing windows 10 in my new VN7-571G and the wireless is not working. It never had: even during the installation it was not recognized. I run a script to gather the data , which is . lspci -knn | grep Net -A2 output 03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:003e] (rev 20)         Subsystem: Lite-On Communications Inc Device [11ad:0804]  The OS behaves like it has no wifi card. I do not see wifi settings in network settings I'm not a linux power user, so I do not know what to do to solve the issue. What should I do to make it work?

I bought a rtl8811au chipest based usb wifi for my work stationd that supports dual band. But when I plugged in the usb my ubuntu doesn't recognized it. So I had to find the driver and compiled it 'cause the one inside the usb package was not compatible with the last kernel version.  My experience with some drivers get from github platform was unsatisfied.  All the drivers I tested are an issue in my user experience. It seems that, with these drivers, my wifi usb stops working randomly, specially when the browser is open and it loads some javascript.   In that context the ping command works normally and all the other connections such as p2p like torrent, or app like telegram.  When that issue shows up, I have some options:   Waiting to work again with do nothing Unplug and replug the usb dongle Restart network service or turn off and turn on wifi   With all these options I have to wait and it is so heartbreaking !  So I think that the problem is relative to the driver 'cause I get it from github and it can contain some error.  I tried drivers like:         and the problem still persists on all these drivers.  Do you know some driver that works properly ?

It worked, the it dropped, then it worked, now it won't connect to wireless. Brand new Asus laptop that came with ubuntu is connected. The problem seems to be with Ubuntu. It keeps asking for authorization codes for my neighbors signals as well as my signal which the asus is connected to.

I need a PCI wireless adapter that works well with Ubuntu 12.04. I have looked around on the web but a lot of the information is out-of-date or confusing. Could someone point me to a wireless PCI adapter on Newegg or Amazon that they know works well with Ubuntu 12.04? I would really appreciate it.

I have dual booted my Windows 8 laptop with Ubuntu 14.04. The wifi driver is Realtek rtl8723be. It didn't use to work but I updated the kernel to 3.18 and reinstalled the driver and that seemed to solve the problem for a few hours. Then it would be connected for around 30 minutes and then the connection would stop, even though the icon on the system tray would still indicate it's connected. The only thing that works is restarting the computer but then, again, after 30 minutes the connection stops.
