Re: [SOLVED] Networking wireless connection on Lenovo G500

There is no wireless hardware in that output.  Are you sure the machine has wireless?  What is a Lenovo 500?  That looks like an incomplete model specification.  A lenovo 500 is a bluetooth speaker.  Is this a G500, Y500, T500, or something else?

Re: [SOLVED] Networking wireless connection on Lenovo G500

Sometimes the wireless interface can be disabled from the firmware (BIOS) options -- check yours (if you are sure it has a wireless card).

Re: [SOLVED] Networking wireless connection on Lenovo G500

There are drivers for Windows.

My bad it is the laptop Lenovo G500.

Actually it has general wireless problem with any GNU/Linux distro I've tried and also on live CD's like the Kaspersky's.

You were right, it was disabled in the BIOS.

I see now it the above

02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
	Subsystem: Lenovo Device 0611
	Kernel driver in use: bcma-pci-bridge
	Kernel modules: bcma

and I see it is not supported, am I right?

Re: [SOLVED] Networking wireless connection on Lenovo G500

It is not supported (according to that page) by the b43 driver.   Try using the broadcom-wl driver.   But first, make sure you have installed the b43-firmware package. It is required by b43 and web pages have been known to be outdated.

Re: [SOLVED] Networking wireless connection on Lenovo G500

Before that, can we see the output of the following

lspci -vvn -d 14e4:

I' ve installed the broadcom-wl driver and the b43-firmware pachage.

and also:

lspci -vvn -d 14e4:

Re: [SOLVED] Networking wireless connection on Lenovo G500

Of course I reboot, but I still can't use the gnome-network-manager.

Also the last status

[panayotis@lazaretto ~]$ iwconfig
wlp2s0    IEEE 802.11abg  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=200 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          
lo        no wireless extensions.

enp1s0    no wireless extensions.

Re: [SOLVED] Networking wireless connection on Lenovo G500

Can we keep Gnome and NetworkManager out of the stew for now?   They are fine tools, but they tend to obscure things.

What is the output of sudo wlp2s0 wlo1 scan   ??
That may not work.  If not, then try sudo iwlist scan    This command is deprecated, but I don't recall if broadcom-wl uses nl80211 or if it only uses the old wireless extension interface.

Re: [SOLVED] Networking wireless connection on Lenovo G500

iwlist scan
wlp2s0    Interface doesn't support scanning : Network is down

lo        Interface doesn't support scanning.

enp1s0    Interface doesn't support scanning.

Re: [SOLVED] Networking wireless connection on Lenovo G500

And the first form (iw) did not work?
What is the output of ip link  ?
What if you try sudo ip link set wlp2s0 up
And, for good measure, the output of rfkill list

Re: [SOLVED] Networking wireless connection on Lenovo G500

I opened another thread [SOLVED] Trying to install and work the Broadcom wireless-BMC43142 which continues the discussion for the same issue about wireless networking on Lenovo G500.
