I have recently started to dual boot ubuntu 17.04 with Windows 10. I am able to connect to my LAN via a wired connection, but wifi shows "disabled" even after checking "enable wifi."  I have posted the relevant information in the link below.    System: Lenovo Legion y520

First of all im sorry if this thread is duplicated with another one, but i didnt find a solution for the problem.  So i bought new laptop (Lenovo Y520) and setup dual boot Win10 with Ubuntu 16.04 and wireless doesnt work for the ubuntu (LAN works).  ifconfig  enp4s0    Link encap:Ethernet  HWaddr c8:5b:76:da:32:ba         inet addr:192.168.0.102  Bcast:192.168.0.255  Mask:255.255.255.0       inet6 addr: fe80::62bc:4b27:ec0f:1d9c/64 Scope:Link       UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1       RX packets:18584 errors:0 dropped:0 overruns:0 frame:0       TX packets:12706 errors:0 dropped:0 overruns:0 carrier:0       collisions:0 txqueuelen:1000        RX bytes:20071392 (20.0 MB)  TX bytes:1500456 (1.5 MB)  lo        Link encap:Local Loopback         inet addr:127.0.0.1  Mask:255.0.0.0       inet6 addr: ::1/128 Scope:Host       UP LOOPBACK RUNNING  MTU:65536  Metric:1       RX packets:1849 errors:0 dropped:0 overruns:0 frame:0       TX packets:1849 errors:0 dropped:0 overruns:0 carrier:0       collisions:0 txqueuelen:1        RX bytes:200236 (200.2 KB)  TX bytes:200236 (200.2 KB)   .  iwconfig  wlp3s0    IEEE 802.11  ESSID:off/any         Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm          Retry short limit:7   RTS thr:off   Fragment thr:off       Power Management:on  enp4s0    no wireless extensions.  lo        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?

As my laptop does not have Ethernet port, to set up wireless, I need to install drivers offline.  My Ubuntu version is 14.04.3, and kernel version is 3.19.0-25-generic.

Now I am not sure what to try next. I am not Ubuntu expert, and would appreciate any help.  Thanks a lot in advance.

I installed Ubuntu 10.10 on my Dell Inspiron 1521 and the LAN/Ethernet card was working perfectly but Ubuntu was displaying a message about not installing the Wireless drivers because it was restricted or something along that line.  I then went to the Synaptic Package Manager, searched for all Broadcom packages and installed them. So far so good.  I restarted my computer and to my surprise, my wireless works but my lan isn't! What the heck could be wrong?  I then uninstalled/removed all the packages I installed earlier hoping my ethernet would start working again but hey, nothing changed. My wireless card works and the ethernet still doesn't.  Is there any way of getting this fixed?  I checked and found my network devices were:   Broadcom Corporation BCM4401-B0 100Base-TX (rev 02) Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

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 am connecting to a WiFi network through my laptop in Ubuntu. Now I need to share my Internet connection with my wife's netbook because her netbook is not able to connect to that WiFi network directly, because of its weak signal.  How can I do that in Ubuntu?

I have a Dell Vostro 5490 with Ubuntu 18.04 installed in dual boot with Windows 10. I currently have no WIFI. I have tried to update and upgrade my packages, and I have also followed  guide, but without success. Except for the things mentioned, my Ubuntu is completely stock, I have not done any other modifications. Please help me out with this issue, any help would be greatly appreciated!

I recently upgraded to Ubuntu 13.04 from Ubuntu 12.10. However, since then although my wireless network is detected, I cannot connect to it.  Ubuntu keeps on trying to reconnect with the network but is not successful. Same machine on Windows 8 I am able to connect to the same wireless network.  Also, Ethernet is working fine as I am able to connect to the same network through Ethernet on Ubuntu.  My lspci -nn output is   12:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) 13:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

I do not want to switch to using Windows again.

I recently upgraded to ubuntu 18.04 but I'm facing issues with the wired connection. First off, I must say that the wifi connection is working fine.  When I start my computed I don't even get the wired network icon. Going into the settings/Network parameters, I don't see anything about wired connection (only VPN and proxy).  Thus I tried to understand what was happening and I used a couple of different commands:  ~$ lshw -C network  WARNING: you should run this program as super-user. *-network                     description: Wireless interface    product: Wireless 8265 / 8275    vendor: Intel Corporation    physical id: 0    bus info: pci@0000:01:00.0    logical name: wlp1s0    version: 78    serial: 00:28:f8:f8:80:b8    width: 64 bits    clock: 33MHz    capabilities: bus_master cap_list ethernet physical wireless    configuration: broadcast=yes driver=iwlwifi driverversion=4.15.0-  22-generic firmware=34.0.1 ip=10.4.26.243 latency=0 link=yes multicast=yes wireless=IEEE 802.11    resources: irq:144 memory:dc100000-dc101fff *-network DISABLED    description: Ethernet interface    physical id: 2    logical name: enx3c18a070d46d    serial: 3c:18:a0:70:d4:6d    size: 1Gbit/s    capacity: 1Gbit/s    capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation    configuration: autonegotiation=on broadcast=yes driver=r8152 driverversion=v1.09.9 duplex=full link=no multicast=yes port=MII speed=1Gbit/s   Then I decided to enable the ethernet interface as follows  sudo ip link set enx3c18a070d46d up   The result of the "lshw" command does not show DISABLED anymore. The wired connection icon came back but still no internet connection and now showed the following message  Wired unmanaged   I would be very interested if any of you have an idea about how to solve this problem.  Thank you and have a good day.  Finally, here are the results of a couple of commands (note that ifconfig is obsolete on ubuntu 18.04)  ~$ ip link show 1: lo: &lt;LOOPBACK,UP,LOWER_UP&gt; mtu 65536 qdisc noqueue state UNKNOWN     mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: wlp1s0: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000 link/ether 00:28:f8:f8:80:b8 brd ff:ff:ff:ff:ff:ff 3: enx3c18a070d46d: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc     fq_codel state UP mode DEFAULT group default qlen 1000 link/ether 3c:18:a0:70:d4:6d brd ff:ff:ff:ff:ff:ff  ~$ ip addr show 1: lo: &lt;LOOPBACK,UP,LOWER_UP&gt; mtu 65536 qdisc noqueue state UNKNOWN  group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo    valid_lft forever preferred_lft forever inet6 ::1/128 scope host     valid_lft forever preferred_lft forever 2: wlp1s0: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc mq state  UP group default qlen 1000 link/ether 00:28:f8:f8:80:b8 brd ff:ff:ff:ff:ff:ff inet 10.4.26.243/23 brd 10.4.27.255 scope global dynamic noprefixroute wlp1s0    valid_lft 42269sec preferred_lft 42269sec inet6 fe80::11e5:2546:9014:171b/64 scope link noprefixroute     valid_lft forever preferred_lft forever 3: enx3c18a070d46d: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc  fq_codel state UP group default qlen 1000 link/ether 3c:18:a0:70:d4:6d brd ff:ff:ff:ff:ff:ff inet6 fe80::3e18:a0ff:fe70:d46d/64 scope link     valid_lft forever preferred_lft forever

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?

Recently, I bought a Lenovo T470 with preinstalled Windows 10. I install Ubuntu 16.04 in parallel by USB boot. Wifi connections are not displayed as in many other posts.  My home directory is encrypted, in case it is relevant.  After checking, there no Wifi / network device available.  lspci -n -d 14e4   ( no response )  iwconfig enp0s31f6  no wireless extensions. lo         no wireless extensions.   Neither is any wireless driver displayed in settings.  I suspect that Ubuntu cannot recognize my wireless device. Is there any suggestion / more information needed to solve the problem?

This is what I got when I typed   $ sudo lshw -C network   into the terminal...  description: Ethernet interface        product: RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller        vendor: Realtek Semiconductor Co., Ltd.        physical id: 0        bus info: pci@0000:07:00.0        logical name: enp7s0        version: 0a        serial: ec:b1:d7:df:8d:40        size: 100Mbit/s        capacity: 100Mbit/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 autonegotiation        configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl8107e-2_0.0.2 02/26/15 ip=10.50.18.72 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s        resources: irq:48 ioport:3000(size=256) memory:c3104000-c3104fff memory:c3100000-c3103fff   *-network DISABLED        description: Wireless interface        product: Wireless 3160        vendor: Intel Corporation        physical id: 0        bus info: pci@0000:08:00.0        logical name: wlp8s0        version: 83        serial: 34:e6:ad:9b:9c:63        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless        configuration: broadcast=yes driver=iwlwifi driverversion=4.4.0-47-generic firmware=16.242414.0 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn        resources: irq:52 memory:c3000000-c3001fff  I don't think the card is recognised with ifconfig   enp7s0    Link encap:Ethernet  HWaddr ec:b1:d7:df:8d:40             inet addr:10.50.18.72  Bcast:10.50.31.255  Mask:255.255.240.0           inet6 addr: fe80::18b2:f378:6027:7c2b/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:15630 errors:0 dropped:0 overruns:0 frame:0           TX packets:7899 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            RX bytes:6370690 (6.3 MB)  TX bytes:1605183 (1.6 MB)  lo        Link encap:Local Loopback             inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:65536  Metric:1           RX packets:2709 errors:0 dropped:0 overruns:0 frame:0           TX packets:2709 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1            RX bytes:217671 (217.6 KB)  TX bytes:217671 (217.6 KB)   but I think it's recognised in $ sudo lspci -vnn    08:00.0 Network controller [0280]: Intel Corporation Wireless 3160 [8086:08b3] (rev 83)     Subsystem: Intel Corporation Dual Band Wireless AC 3160 [8086:8070]     Flags: bus master, fast devsel, latency 0, IRQ 52     Memory at c3000000 (64-bit, non-prefetchable) [size=8K]     Capabilities: [c8] Power Management version 3     Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+     Capabilities: [40] Express Endpoint, MSI 00     Capabilities: [100] Advanced Error Reporting     Capabilities: [140] Device Serial Number 34-e6-ad-ff-ff-9b-9c-63     Capabilities: [14c] Latency Tolerance Reporting     Capabilities: [154] Vendor Specific Information: ID=cafe Rev=1 Len=014      Kernel driver in use: iwlwifi     Kernel modules: iwlwifi  Edit: $ rfkill list prints   0: acer-wireless: Wireless LAN     Soft blocked: yes     Hard blocked: no 1: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no 2: hci0: Bluetooth     Soft blocked: no     Hard blocked: no   I'd greatly appreciate any help, Thanks in advance.

I am an Ubuntu newbie. I have a HP DM1 laptop with Ralink RT5390 wifi card. It has the ability to connect on wifi direct with my Nexus 7 in Windows while using latest drivers located at Mediatek site. But I am unable to use wifi direct in Ubuntu. I found wpa2_supplicant supports this and installed the same, but still wifi direct is not functioning.  Can anyone help?

I know this problem has been stated before, but none of the solution worked for me. I'm running Ubuntu 14.04 on a Asus U32 laptop, alongside Windows 8. Recently I've updated from 12.04 to 14.04 and the wifi can't be enable now. Before upgrading, it worked perfectly. I have no hardware button to switch it on/off, so it must be software related. On windows 8 the wifi is working ok.  I've tried Fn+F2 to enable it, but it also goes on for about 1 second. Also, I've tried the rfkill unblock command in terminal, but nothing.  I don't know what else should I try.

I have some problems on my Asus notebook since I upgraded to Ubuntu 13.10:   Networking (wifi and lan) won't work after resume from suspend. I've seen many posts about this but they wouldn't work for me (adding iwlwifi to the list of loaded modules).   I couldn't find anything on that problem, and I don’t know where to look at to solve that. Is there any information I can add?
