My laptop is Dell Inspiron 17R 5720. My OS is Ubuntu 13.10. I was using WiFi before but one day it stopped working.

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?

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 have had some  wireless USB problems and I have decided to just try and use the piggyback-a-laptop method.I have an Ethernet cord, a Ubuntu 15.04 Desktop and a Peppermint 5 laptop.I have tried the usual methods, I have not done any IP address and I am kinda frustrated, I've heard stuff about gateway problems, I might go crawling back to windows after 6 years of Linux  All help is greatly appreciated

The wifi on my asus x550ca laptop is not working. Ethernet works fine in ubuntu but wifi does not work. Wifi works just fine when I boot up windows 8.1 though. Is there any special driver I have to install?

I have a virtual machine installed on my Windows 8.1 laptop with Ubuntu installed on it, but when I open the Network menu it doesn't show any wireless networks. How do I connect Ubuntu in my virtual machine to a wireless network that my host machine is detecting?

I just purchased a Lenovo Yoga 730 15" laptop, and installed Ubuntu 16.04 in place of Windows 10. Install seemingly worked fine, but now I have no wifi device available.  Tried a reinstall just to be sure, and the same issue is happening. I don't believe it to be a hardware issue, as wifi was working without issue on Windows before I wiped it out.  When I run rfkill list I see:  0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no   But when I run lspci I only see one item in the list claiming to be a network device:  3a:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b822 (rev ff)   I have a USB wifi adapter and that gets me connected without issue, but obviously that is not the desired solution.  Does anyone have any insight on what might be causing the issue?

I would like to get a list of the wireless networks available. Ideally this would be via some C call, but I don't mind if I have to kludge it with a system call. Even better if the required C call or program doesn't require some exotic 3rd party package.  The internet seems to suggest I use sudo iwlist &lt;interface&gt; scan which does seem to do the trick from the command line, but I'd rather not require root permissions. I only want to see the basics, not change anything.

I booted Ubuntu 17.04 live on my Fujitsu Amilo Li3710 laptop and I was surprised to see that I couldn't connect to wifi. I tried to connect to my router and my phone as a hotspot but neither work.  I can see wifi networks and when I try to connect it asks for the password, seemingly tries to connect but then it doesn't connect. It gives no visible feedback after failed trials.  Disabling mac filtering and removing the wifi password makes no difference. I tried Ubuntu, Ubuntu Gnome, Ubuintu MATE and Lubuntu, it's the same everywhere.  I have Ubuntu 16.10 and Windows 10 installed on the laptop, they have no problem connecting.  Is there anything I can do? Or is support for my hardware over in the kernel?

I have a Dell PowerEdge T710 I'm trying to run as a home server. I have successfully installed Devuan, however I failed to set up the network properly. I'm wondering if there's any way to add the non-free network drivers for its Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet controller. I'm also open to reinstalling, but if I'm gonna do that I'd like some guidance on adding the proper network firmware to the installation image. I'm also open to giving up and using the debian non free net install iso. (I'm using Devuan to play with other init systems eventually but its not super important that I stay with this distribution)
