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.

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 have checked and made sure that "Use proprietary driver" is checked in System Settings > Software &amp; Updates > Additional Drivers and I have run sudo apt-get install --reinstall bcmwl-kernel-source I have also restarted after every driver change to finish the changes. Is there anything else I should try?

I've tried everything I can think of. Resetting the router, changing the channel number and band.   The internet connection is fine, and then just hangs for a minute or 2, then returns to normal.   The wifi icon remains connected, and I have the latest 10.10.4 update installed. At first I thought it was a DNS bug with Yosemite, and have played with the settings such as changing DNS provider, changing the IPV6 to IPV4 only etc.  Driving me nuts. Has anyone had a similar problem? I've checked the surroundings with wifi scanners and have chosen the best channel available.     One thing I have noticed, it seems a lot more reliable on 5GHz as opposed to 2.4Ghz It seems to affect my Macbook Pro Retina 13in Early 2015 a lot more than the other devices on the network. I'm using a Virginmedia  1.

Part 1  I upgraded 2012 MBA to 2015 MBPr (I loved Mint 17.1 Rebecca on the MBA but graphics/kernel issues means I need to wait till 17.2 to use Mint again)  I've managed to install Ubuntu on an SDcard. It boots and works. Great tutorial on this is .  I cannot get the Wi-Fi to work.  Used Terminal to determine the chipset:   $ lspci -nn | grep 0280 03:00.0 Network controller [0280]: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)   I tried enabling the driver in Software &amp; Updates → Additional Drivers. Ubuntu freezes so that's a no go.  I used terminal to install the following blobs/drivers (not sure what you call them) offline:  sudo dpkg -i bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu2_amd64.deb dkms_2.2.0.3-2ubuntu3_all.deb   This caused the system to freeze at:  DKMS: install complete   I rebooted and tried reinstalling using Ubuntu Software Installer which caused it to hang.  I've not messed with anything else. Can someone please explain what I am doing wrong?  Okay, here's part 2:  I tried installing bcmwl-kernel-source_6.30.223.30+bdcom-0ubuntu3_amd64.deb.  This is the error message:  Selecting previously unselected package bcmwl-kernel-source. (Reading database ... 170952 files and directories currently installed.)

I did a fresh install of Ubuntu 16.04.3 on my laptop, which is also running Windows 10. The install was successful and during the process I was able to connect to my wifi network with no issues (I can still do so when using Windows) - but now I can't see any networks at all when trying to select one. I can use a wired connection.  Using 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: 0.1    bus info: pci@0000:01:00.1    logical name: enp1s0f1    version: 12    serial: 80:fa:5b:35:06:d7    size: 1Gbit/s    capacity: 1Gbit/s    width: 64 bits    clock: 33MHz    capabilities: pm msi pciexpress msix vpd 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=rtl8411-2_0.0.1 07/08/13 ip=192.168.0.21 latency=0 link=yes multicast=yes port=MII speed=1Gbit/s    resources: irq:127 ioport:e000(size=256) memory:df214000-df214fff memory:df210000-df213fff *-network UNCLAIMED    description: Network controller    product: Wireless 8260    vendor: Intel Corporation    physical id: 0    bus info: pci@0000:02:00.0    version: 3a    width: 64 bits    clock: 33MHz    capabilities: pm msi pciexpress cap_list    configuration: latency=0    resources: memory:df100000-df101fff   I thought it was maybe an issue with missing drivers because the driver is unclaimed, so I copied the driver for 8260 from  to /lib/firmware, but still nothing.

I'm mostly curious, but why aren't network interfaces in /dev? Are there any other kinds of devices that aren't represented as a node under /dev?

I just installed the OS on my laptop and at first wifi didn't work. After connecting to ethernet and updating everything, the wifi is working. But it disconnects here and there and requires me to reload the service or reboot. The bluetooth on the card does not work at all. It is seen and hciconfig shows an address for it. However, I cannot find bluetooth devices with it. I have seen a lot of different posts with this card but most of them are older. Where can I go from here.

I have a problem with my network adapter after upgrading from 13.04 to 13.10. The adapter works for literally several seconds after I establish the connection but then it looks as if it got clogged somehow.  This is what I see amongst my devices:  ~$ lspci | grep -i wireless 02:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01) ~$ uname -a Linux bubek 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux ~$ lsmod | grep 80211 lib80211_crypt_tkip    17387  0  lib80211               14040  2 wl,lib80211_crypt_tkip cfg80211              401436  1 wl   Now, how does is behave.

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 assuming that at some point I may have mistakenly assigned the wrong driver to my wireless card while attempting to boost signal strength. Is there any commands that would allow me to reclaim my wifi card and set the correct drives?  It took a minute to find it, but I think this is the command that did it.   sudo apt-get install firmwire-b43-installer b43-fwcutter   which did not install, or this one,   sudo apt-get remove bcmwl-kernel-source   In the windows driver installer the files were netathr.inf and netathrx.inf. The program marked them with an error of which I can't remember.  I have re-installed bcmwl-kernel-source and nothing. I don't even know if it is related to my problem.   My card is   Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01).   I have Ubuntu 14.04 LTS in which I have just upgraded to in hopes that it would fix this same problem I experienced in 12.04 LTS.   I'm currently running wifi from a usb controller, but I need the internal card to work because this wifi usb controller is not mine, nor is it small. It is very large for what it is and I would much rather have my laptop work like it is supposed to.  sudo lshw -C network    *-network UNCLAIMED        description: Network controller        product: AR9285 Wireless Network Adapter (PCI-Express)        vendor: Qualcomm Atheros        physical id: 0        bus info: pci@0000:07:00.0        version: 01        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress bus_master cap_list        configuration: latency=0        resources: memory:f0100000-f010ffff   In case more info is needed.  rfkill list all  0: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no   nmcli nm  RUNNING         STATE           WIFI-HARDWARE   WIFI       WWAN-HARDWARE   WWAN       running         connected       enabled         enabled    enabled         enabled   iwconfig without usb controller  eth0      no wireless extensions.  lo        no wireless extensions.

I updated Ubuntu to 14.04 LTS and I can no longer see my network - No network devices available shows in the network drop down menu. Networking is enabled and if I choose to boot my Dell Inspiron 1300 from the network I do see some activity on the card but none in Linux. Both lights on the nic stay on permanently.

I tried to install the driver for my new wifi usb stick with MT7610U Chipset from 7Links but had no luck. I tried to install it via github and from the original sources but always had some compiling errors. I also tried it with wpa supplicant and the wext driver but could not get it running. lsusb tells Bus 003 Device 006: ID 0e8d:7610 MediaTek Inc. and iwconfig only shows my old wifi stick and two other ethernet cards.   I'm trying to install the driver on ubuntu 17.10.  Is there any way to get it running and can someone tell me how?  Thanks in advance

I've used Ubuntu before, but I'm still very new. I just installed 16.10 on a new computer yesterday, and the Wi-Fi has been considerably slower than my Windows laptop. I put the computer together mainly to play Dota 2, and I experience decent ping but constant 5%-10% packet loss while playing. Occasionally, after the computer has been left on for a while, the Wi-Fi connection will drop completely- I can still see networks in the drop down menu, including my home network, but my computer will not reconnect without a reboot. I've looked all over for a solution, but my inexperience has prevented me from getting anything to work. My Wi-Fi card is a Ralink RT2561/RT61, here's some info  The output of sudo lshw -C network   *-network                          description: Wireless interface         product: RT2561/RT61 802.11g PCI         vendor: Ralink corp.         physical id: 6         bus info: pci@0000:01:06.0         logical name: wlp1s6         version: 00         serial: 00:0e:2e:de:df:c0         width: 32 bits         clock: 33MHz         capabilities: pm bus_master cap_list ethernet physical wireless         configuration: broadcast=yes driver=rt61pci driverversion=4.8.0-22-generic firmware=0.8 ip=192.168.1.107  latency=64 link=yes multicast=yes wireless=IEEE 802.11         resources: irq:17 memory:dfef8000-dfefffff   Here is the output of sudo iwconfig:   *-network                          description: Wireless interface         product: RT2561/RT61 802.11g PCI         vendor: Ralink corp.         physical id: 6         bus info: pci@0000:01:06.0         logical name: wlp1s6         version: 00         serial: 00:0e:2e:de:df:c0         width: 32 bits         clock: 33MHz         capabilities: pm bus_master cap_list ethernet physical wireless         configuration: broadcast=yes driver=rt61pci driverversion=4.8.0-22-generic firmware=0.8 ip=192.168.1.107  latency=64 link=yes multicast=yes wireless=IEEE 802.11         resources: irq:17 memory:dfef8000-dfefffff   I'm at a loss, I'm very bad at this.
