Help please, wlan0 doesn't show up

@Shadow 7
Hello. Thank you for your long answer!
I sadly ended at the start with

Code:

sudo apt-get install firmware-realtek
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package firmware-realtek

Any ideas?

By the way I am new at linux so if you please could talk to in more detail, I would really appreciate it!
Thank you very much,

Adam

Hi Adam...

As I mentioned previously in post #10, I'm pretty sure this package is not available in Ubuntu's repositories. You would need to download and install it as a .deb from the (Debian) link I gave on that post. However, I'm not sure if the firmware is kernel specific, so downloading from Jessie may be fine, or you may need one of the other versions (or maybe none will work.) You would need to give it a try and see how it works.

Regards...

that begs the question is there any wifi routers close by that you can pick up a signel. prob'ly is .. just needed to be asked. IMO

@ardvark71
Thanks. I ended up downloading both. Tried to install it, looked good, but it ended like this:

Code:

Unpacking firmware-realtek (from .../firmware-realtek_0.43_all (1).deb) ...
dpkg: error processing /home/adam/Downloads/firmware-realtek_0.43_all (1).deb (--install):
 trying to overwrite '/lib/firmware/RTL8192E/main.img', which is also in package linux-firmware 1.95.1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
 /home/adam/Downloads/firmware-realtek_0.43_all (1).deb

All I could think of was uninstalling package linux-firmware, but to me it doesn't really seem smart, but I might be wrong ..
What next?

@BW-userx
As I mentioned previously, there is working wifi router just next to me, working. Thanks for idea thou

Thank you guys,

Adam

kelw, knowing that at least I can sleep better..

that little (1) says you are working with a copy of one you all ready have, fyi.

Debian:
Broken_pipe

Ubuntutututu

dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

poky · 02-01-2016, 10:34 AM

Hello,
thank you for your input. I finally successfully installed the Debian .deb package. Rebooted and it still can not find any wi-fi signals..

I hope you guys aren't running out of ideas ..

Do you want me to copy here any result of a command that could help you determine the problem?

Any other ways to make it work?

Thank you very much and sorry for my broken English,

Adam

BW-userx · 02-01-2016, 10:44 AM

have you ever gotten anyother Linux install and have wifi ever on that system?

Nope. This is 14days new notebook bought just for this work. Oo
I only tried newer Deft as LIVE USB and wifi worked. Don't know if it answers your question..

Since you've installed the drivers that I mentioned in my initial post, can you open a terminal and post the results from...

Code:

iwconfig

Code:

lsmod

Perhaps they might give us more clues.

Regards...

Hi Adam...

I see from your "lsmod" report, the modules for your device appear to be loaded and running...

Code:

rtl8723be             134748  0 
rtlwifi               133500  1 rtl8723be

That's a start, I think.

Now, if you would, please restart your system and post the results of these commands...

Code:

dmesg | grep -iC 3 "wlan0"

Code:

rfkill list

If the dmesg command doesn't work, you can try these variants...

Code:

dmesg | grep -iC 3 wlan0

Code:

dmesg | grep wlan0

And if that doesn't work, just run this...

Code:

dmesg

and then go through it and copy and paste only the information with "wlan0" in front of it. Please do not post the entire report.

Regards...

poky · 02-01-2016, 11:49 AM

@ardvark71
Thank you!

The first command worked, I guess.

Code:

dmesg | grep -iC 3 "wlan0"

[   17.338387] rtl8723be-0:rtl8723be_enable_hw_security_config():<0-0> The SECR-value cc 
[   17.476889] rtlwifi-0:rtl_pci_start():<0-0> rtl_pci_start OK
[   17.495790] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[   17.497052] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

[   17.520232] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready

or you still want me to go through the normal one?

Code:

rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hp-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no

Thanks,
Adam

ardvark71 · 02-01-2016, 11:56 AM

Hi Adam...

Out of curiosity, is there any difference with one of the alternative commands...

Code:

dmesg | grep wlan0

Thanks!

No problem, thank you

ardvark71 · 02-01-2016, 12:11 PM

Hi Adam...

Ok, thank you. Bear with me here.

What happens when you enter this command...

Code:

ifconfig wlan0 up

This may be a driver/firmware issue but I wanted to see how things look on this end.

Regards...
