Lenovo g560 eth0 no wireless extensions

[petre.tudor]

After some updates that required restart, the wireless stopped working.
My wireless card: is Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 02)


Can someone please point me to the right direction into solving this?

Thanks!

You posted details about your wired ethernet card. Please run and post:

lspci -nn | grep 0280
rfkill list all

[petre.tudor]

Sure

05:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

AND

0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

This part was:

0: ideapad_wlan: Wireless LAN
    Soft blocked: yes

But I run this: rfkill unblock all and now is: Soft blocked: no


Thanks for your reply!

Your Broadcom works best with the STA driver. Let's try to re-install it and see if we can get it going.

sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
iwconfig

[petre.tudor]

After the first command I got lots of data, but something went wrong:

FATAL: Module wl not found.

Second:

FATAL: Module wl not found.

Still:

eth0      no wireless extensions.
lo        no wireless extensions.

It will be helpful to see the exact errors. Can you please run it again and copy and paste the terminal output here? May we see:

lsb_release -d

sudo apt-get install --reinstall bcmwl-kernel-source

I was under the impression that I've mentioned ubuntu version, sorry: Ubuntu 12.10

Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed.

Feel that little itch right there? That's known as a bug! You lucky Ubuntu person!

Ideally, if the kernel source were not installed, apt would...do what?...install it! Let's help it along:

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
iwconfig

Now do we have wireless?

[petre.tudor]

It works!

Thank you for your time!
This is all to much for me


Have a nice day/week/year/life!!!
