Problem with wireless 14.04 (RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller)

Question

I just installed Ubuntu 14.04, and am having trouble getting my wireless working. I've run Ubuntu desktops before, but I just can't get it working, and I'm not sure what to do.

This is the output of sudo lshw -C network

*-network UNCLAIMED

       product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

So the *-network UNCLAIMED strikes me as being a problem, but I'm not sure what to do about it. Currently tethering with my phone, and hoping to stop that soon. It's almost 2am where I am so I'm going to bed, really hoping someone has some insights overnight!

This update was requested. This is lspci -nnk

07:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168]
(rev 06)    Subsystem: Gigabyte Technology Co., Ltd Motherboard
[1458:e000]     Kernel driver in use: r8169

Solution 1

modify /etc/network/interfaces:

nano /etc/network/interfaces

put these two lines at the end:

auto eth0
iface eth0 inet dhcp

save and reboot.

Solution 2

*-network UNCLAIMED means that you don't have the driver installed. Just try installing the linux backports. Look the following wiki and perform the steps.

https://help.ubuntu.com/community/UbuntuBackports

Once done, do reboot and check.

Solution 3

The needed driver r8169 is installed in all recent Ubuntu versions by default. Try to load it:

sudo modprobe r8169

Does the ethernet come to life? Or is there an error? Are there any clues in the log?

dmesg | grep r8169

Once we have more details, I will edit this answer to propose a solution.

Please update your question with lspci -nnk | grep Net -A2 output, thanks.

The question makes no sense. The controller you posted in the title is not wireless. It is an Ethernet controller.

[Pilot6]

There is no pci wireless adapter? Is it a usb dongle?

[Trev]

Ya It's a usb dongle.

[Trev]

I'm not sure if this is relevant, but there is a little light on the usb dongle that comes on and sort of flashes while I am running windows, when in ubuntu there is no light at all.

I have been doing my best to read up, but I'm not very experienced. I did find a thread that recommended compiling this information, perhaps it will be able to help someone help me: pastebin.com/hQmMgCKc

You posted the script itself, not the result of running the script. May we also see: lsusb. Thanks.

[Trev]

Hey chili I actually found a thread where you solved this problem previously, and what you suggested there worked for me. Here is a link to it for anyone who navigates here. Good luck to you! ubuntuforums.org/showthread.php?t=2168426

Ok I did "sudo modprobe r8169" it asked for my password. Then I did dmesg | grep 8169 This was the output: [ 1571.002628] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded [ 1571.002641] r8169 0000:07:00.0: can't disable ASPM; OS doesn't have ASPM control [ 1571.003343] r8169 0000:07:00.0 eth0: RTL8168evl/8111evl at 0xffffc9000504a000, 50:e5:49:31:e0:bf, XID 0c900800 IRQ 31 [ 1571.003346] r8169 0000:07:00.0 eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko] [ 1571.155353] r8169 0000:07:00.0 eth0: link down
