Bluetooth earphones work fine until sleep. After resuming from sleep however, they appear to connect for a brief moment before disconnecting. On blueman, the error given is Resource temporarily unavailable. This issue arose only after updating to 18.04 LTS.

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 am unable to connect to the internet via Ethernet or WiFi.  Let's fix the Ethernet issue, eh?  I just installed Ubuntu 12.04 on an HP Mini 1000.  Previously it had 11.04, and the Ethernet didn't have any issues then.  I am a Linux beginner, and I have been working on this issue for the past several days without any progress.

I have moved from win 10 to Ubuntu 16.04. I've tried following  and , but still run into problems as the latest kernel version is 4.6.3. I'm still running on the kernel that came installed with Ubuntu which is 4.4.0.  Long story short, my keyboard, touch pad, touch screen, volume and power buttons, the stylus, wifi indicator (top right corner) and camera are not working. I've managed to get the Wifi and Bluetooth working.  Can anyone help me out with writing/finding some patches and re-compiling the kernel?    Please post all updates and issues on   and any contribution is appreciated    and   To get the type cover working run SP4-1 script from

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.

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 know NOTHING about Linux and most of the instructions aren't written for someone like me.

I have a Lenovo G40-70 laptop, which comes with RTL8723be driver.  I'm using Ubuntu 14.04 LTS (with Kernel 3.16.0-38-generic), but this bug also occurs in 14.10 and 15.04.  Even with options rtl8723be fwlps=0 ips=0, the problem is not fixed yet. Wireless is unstable, lots of websites keeps loading forever and Ping command frequently shows data loss. It's very annoying. :(  BIOS version is the latest.  Blacklisting ideapad_laptop also doesn't work.  Sorry my english and thank you!

My wifi card is an Intel® Wireless-AX200 (802.11/a/b/g/n/ac/ax), Bluetooth® 5, and bluetooth is working. I've tried following various guides, however these drivers are apparently yet to make it into the kernel.  Their product brief states linux is supported:    And yet their driver page has no listing for them:    sudo lshw -c network =&gt; mark@m-blade-2019:~$ sudo lshw -c network   *-network UNCLAIMED               description: Network controller        product: Intel Corporation        vendor: Intel Corporation        physical id: 0        bus info: pci@0000:02:00.0        version: 1a        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress msix cap_list        configuration: latency=0        resources: memory:cf300000-cf303fff   *-network        description: Ethernet interface        physical id: 2        logical name: enx0050b6b47e72        serial: 00:50:b6:b4:7e:72        capabilities: ethernet physical        configuration: broadcast=yes driver=cdc_ncm driverversion=22-Aug-2005 firmware=CDC NCM ip=192.168.1.17 link=yes multicast=yes   I'm running kernel version Linux 5.0.0-13-generic, any help is greatly appreciated.

Mac OS X 10.6.4, MacBook Pro, Apple Magic Trackpad.  The trackpad is unresponsive. Right-clicking on the Bluetooth icon in the menu bar shows me gray text that says "Bluetooth not available".  I don't see a system preference item in which to fight with this, but I don't see anything relevant.

I'm trying to use the built-in bluetooth device of my Lenovo Thinkpad E320. It seems to be hard blocked, but i can't find any possibility to unblock it.  rfkill list returns:  0: tpacpi_bluetooth_sw: Bluetooth    Soft blocked: yes    Hard blocked:yes   cat /proc/acpi/ibm/bluetooth returns:  status:     disabled commands:   enable, disable   I tried to enable it by:   Pressing Fn+F9 (Radio controll) echo enable | tee /proc/acpi/ibm/bluetooth rfkill unblock bluetooth Trough the BIOS. But it's not mentioned at all   None of the actions influenced the ouputs above.

I have found that there is a large community suffering from the problems with the WiFi-Bluetooth card Ralink RT-3290. It has been a problem since 2012-2013.  None of the solutions I've found is simple, effective and durable.  I managed, with great effort, some results. But when there is a kernel update, the problems return.  Can anyone provide a simple , effective and lasting solution? Is there a project from Ubuntu's developers to attack the problem?

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?  Update 1 : After Pilot6's comment, I check again and there is still no response.   lspci -knn | grep Net -A2   Update 2 :  lspci 00:00.0 Host bridge: Intel Corporation Device 5904 (rev 02) 00:02.0 VGA compatible controller: Intel Corporation Device 5916 (rev 02) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI (rev 21) 00:1c.0 PCI bridge: Intel Corporation Device 9d10 (rev f1) 00:1c.6 PCI bridge: Intel Corporation Device 9d16 (rev f1) 00:1d.0 PCI bridge: Intel Corporation Device 9d18 (rev f1) 00:1d.2 PCI bridge: Intel Corporation Device 9d1a (rev f1) 00:1f.0 ISA bridge: Intel Corporation Device 9d58 (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (4) I219-V (rev 21) 04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Note - I know nothing about Linux, just switched over from Windows. Also not an accomplished coder.  Installed Ubuntu 16.04 on a Dell laptop; it worked.  Installed it on an HP laptop (model 17 -x061nr) and the wi-fi will not work. In Network Settings, the option to turn Wireless on is present, but when I click it on it immediately switches back off again. I have no Ethernet ports available. I can download something on the Dell laptop and transfer it via flash drive, but that's it.  The HP's network controller is a RTL8723BE PCIe wireless network adapter, from Realtek. Prior to installing Ubuntu on this laptop, it was running Windows 10; the wi-fi worked there. The wireless isn't entirely kaput - the first time I switched it 'on,' the name of my wi-fi network appeared for half a second before the wireless switched off.  I've powercycled the laptop, reinstalled Ubuntu, and disabled, then re-enabled Networking. I looked in Software &amp; Updates; it had one notification that the device is using an alternative driver (Processor microcode firmware for Intel CPUs from intel-microcode (open source)). I've tried enabling the wireless with and without using that device.  I've looked around the forums for similar issues, but haven't found anything quite like this.  Advice? Any further info required?  rfkill list all: 0: hci0: Bluetooth     Soft blocked: no     Hard blocked: no 1: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no 2: acer-wireless: Wireless LAN     Soft blocked: yes     Hard blocked: no   Update: Wi-fi is now enabled. Thanks very much for the help!
