I recently installed Ubuntu onto my external hard drive which is fine apart from the fact it will not allow me to search for or connect to wireless networks. My internal hard drive has Windows 7 installed and the wireless works perfectly fine and always has, so I doubt it's a hardware issue. However, the Ethernet is usable as I have a Huawei mobile wifi device and USB cable and can connect to the internet using that, but its not ideal and I wish to be able to connect to my home hub while I'm using Ubuntu. The name of my wired connection is "geometric".  I ran the wireless info script and the results are here:   I have tried sudo service network-manager restart but that didn't work. Another thread suggested adding the SUSPEND_MODULES line to the config file but that also didn't have any effect.

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 bought a new computer, hoping to dual boot Win 8 and Ubuntu 13.04.  I have successfully installed both OS, but in Ubuntu I have no connection to the internet, even though the ethernet cable is plugged in and internet works perfectly in Win 8. Already in the Ubuntu installer, it says that I have no internet connection.  Things that might be of interest:   I have this motherboard: MSI Z87-G45 Gaming () Internet did not work in Win 8 until I installed the networking drivers that came with the motherboard (Killer Ethernet something) I have tried different installation configurations, tried v. 13.04, 12.04 and 12.10, and tried installing on a separate hard drive. (the fact that the installer says "no internet connection" seems to indicate that the problem has nothing to do with the installation though.) I can't even reach my router at 192.168.0.1.  The motherboard has no wireless capabilities.  If I run the terminal command lspci I get the following output (among other things):       03:00.0 Ethernet controller: Qualcomm Atheros Killer E2200 Gigabit Ethernet Controller (rev 13)   I have spent hours and hours googling, trying many different suggested methods and not quite finding someone who seems to be having the same problem.

I have just moved back to Ubuntu from Windows 7 and a few months ago, I bought a NETGEAR WNA3100 wireless adapter because my old adapter had broken. I plugged in my adapter and it doesn't seem to work, I also used the windows 7 drivers for it and tried them on the program "Windows Wireless Drivers" and they don't seem to recognize the device. However I have heard you need XP drivers but I can't seem to find them on the internet nor find them on the CD.  Could anyone help me get my wireless adapter to work? Any help is greatly appreciate.   P.S I do have internet connection though I have to tether my phone to my computer and then connect my phone to my router.

I plan to install Ubuntu soon on my PC. I currently use a TP-LINK TL-WN822N wireless adapter. I want to know if it will work without additional setup.

I have installed Ubuntu alongside Windows 8.1. But the wifi is not working in Ubuntu (perhaps the drivers are not present), which worked fine in windows. Also I cant connect with Ethernet since my laptop does not have an Ethernet port. So is there any way for me to connect to the internet in ubuntu?

My wifi connection doesnt work properly; it stays connected only for around 5 minutes after I turn on the PC. I'm using Ubuntu 16.04.  I've tried   sudo service network-manager restart   which makes no difference  Same with   killall nm-applet &amp;&amp; nm-applet &amp;   After that I tried   sudo gedit /etc/pm/config.d/config   where I insert this string  SUSPEND_MODULES = "drivername logicalchipname"   But since I don't have permission to modify that file I tried to use chmod on it, which led to  but left me still in the same situation.  $ lspci -knn | grep Net -A3; rfkill list 03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.

I recently installed Ubuntu 14.04 on my Dell XPS 15 9530.  Now, everything except the wireless connection works fine. I've googled, and found  solution, but it didn't change anything for me (i.e. I added "options iwlwifi 11n_disable=1" to "/etc/modprobe.d/iwlwifi.conf").  I'm not sure what next steps I should take to solve this problem. I've read somewhere that updating the kernel might help I ran the command "uname -r" and got "3.13.0-24-generic" back, which implies i have the kernel version 3.13 and not the newest 3.18 according to .  If anyone has an idea what to try next or can point me somewhere, that would be awesome.

I tried to post to this thread  for if I understand their question I am having the same problem, but the answer option won't work for.  After suspend, the wireless is disconnected and the only way to get it to reinitialize/be recognized is to do a full restart.  At first I thought it was my gnome-shell (for lock screen disappeared there with 13.10), but when I switched to the default Ubuntu it's still doing it and it's kinda driving me nuts for I have to reopen all my files and browsers/tabs/windows every time. I don't know how to show the terminal stuff the above asker shows, but it sounds like the same issue and it only started with 13.10 upgrade a few days ago.   Any help would be much appreciated!!! -- Thanks so much, ser.

I'm using Ubuntu 14.04 on my laptop and I can't connect to a specific WiFi networks. I managed to connect to others wifi networks in the past without any problem, and other devices (another laptop with Windows 7 and some Android smarthphones) were also able to connect to this WiFi network. Furthermore, this laptop can connect to the same router through the ethernet cable. So, as a resume, the problem is just between this particular device and this particular WiFi network.  Any hint about what may be happening?  I already tried solutions proposed on these questions but it didn't worked:     It seems that I don't have the iwlwifi but the wl instead. I also tried following those steps but replacing "iwlwifi" with "wl" but nothing.  Edit:

I have to reset my internet connection often to get it to work.  When it does work, it's definitely slower than when I'm on my Windows installation.  My computer uses an RTL8188CE wireless card from Realtek.  I'm running the 64-bit version of Ubuntu 12.10.  Power management is not on.  I've read on other sites that some people fixed the issue pertaining to this wireless card by downloading and installing the drivers from the Realtek site, but it seems as if that only helped people with 32-bit installations.  Anyone have any luck with this specific wireless card?

I've got a new laptop with a wireless card which runs Windows 7.  At work, I put the laptop in a docking station that gives the laptop a hardwired internet connection and functions pretty much like desktop PC.  But there isn't any WiFi signal in my building that I can use, so various portable devices that depend on WiFi  for an internet connection (iPod Touch and Kindle) are hobbled.  I'd like to provide them internet connections without spending more money, if possible.  So what I'd like to do is install some sort of virtual WiFi router on my PC.  Is that possible?    N. B. There is a related (but not identical ) that has an  that I think will work for me.  It won't hurt my feelings if this question is closed with a link to the other question, but I think they require different answers.

I have an old Compaq desktop that my children use to access the internet. The kids have repeatedly managed to severely infect the computer with viruses, and this latest round has been a doozy. A friend recently sold me on Ubuntu as a great windows replacement since it is not prone to viruses, so I decided to to give it a go.  I completely overwrote windows with Ubuntu 12.04 to get rid of the viruses, but I can not figure out how to make the wireless network dongle work. I have Googled the topic and tried to go through some of the solutions, but I don't know what I'm doing and I think I may be making things worse. Can someone help me with this?

I'm having problems with the internet connection on my Ubuntu 13.04. I deleted Windows 7 from my computer (where the internet worked without any kind of problems) and installed Ubuntu 13.04, but now i'm having some trouble here.  I can't connect to the internet using my WiFi, it connects to my router. DEPENDING, on the site that I pings on terminal it doesn't have answer. I can't browse on internet using it and Ubuntu can't connect to archive.ubuntu to download packages or updates.  To used my cable connection I had to restart my notebook some times until it connects and it keeps barely working. It seems like I'm using a 90's internet connection. When I try to download or update certain packages, most of the connections to the server are unsuccessful.   I'd like some help, thanks.

Hi I am new to Ubuntu and Linux. As I am developing a WiFi product, I want to capture the WiFi traffic wirelessly with Wireshark. Having some searching in the web, I know that I can do that with a USB WiFi adapter and Ubuntu. Then I can run the Wireshark in real monitor/promiscuous mode.  Ok so I bought a TP-Link TP-WN722NC (I want to buy the TP-WN722N at first, but the store only has this model). Also I found a laptop and installed the Ubuntu 14.04.1. Then I noticed that I need a driver for this adaptor. So I try to follow the blog post  to install the driver ath9k_htc but seems it was not successful.  Then I downloaded the backports 3.16-1 by running these two commands:  wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.16/backports-3.16-1.tar.gz tar xvf compat-wireless-2.6.38.2-2.tar.bz2   However, after that point do not know what should I do. Could you help guide me to install the correct driver?

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?
