Ubuntu Mate 16.04 Wifi Networks greyed out and disabled

Hi Up until I installed Ubuntu Mate 16.04 LTS (before that I had Ubuntu 1`4.04 LTS with Gnome Metacity) I was able to use the wifi on my Fujitsu Siemens T3010 laptop. However I now find that my wifi has become blocked. I have now also purchased two USB Adapters which are also blocked. I dual boot with XP and I have no problem with the USB Wifi adapters. I have a spare drive that I have used in the laptop with Mint 18 and Zorin but they too block my wifi adapters .
I have read and copied and pasted so many ‘solutions’ into my Terminal without any success. Any ideas what I am doing incorrectly? I have noted that a few other people have also had similar issues but all solutions are different. Any suggestions will be highly appreciated.

Hello
Please provide the output of:

sudo lshw -C network

Hi ouroumov,

Thank you for taking the time to adopt this.

As requested I have copied and pasted the output:

I have left the USB adapter (TL-WN725N in) attached. Even the adapter
which is recognized by the system has been disabled - hope the info will
be of use.

Hi @matebod,

try booting again without the 2nd WiFi stick inserted, if your on-board WiFi adapter doesn’t work, plug in your USB WiFi stick and it should bite as I had a similar problem recently.

Try updating again if you get a connection!:

Hi wolfman, I tried your suggestion of rebooting without USB Wifi adapter
and it was the same. The wifi network was greyed out for both the onboard
and the USB… I plugged the usb back in and both the wifi network adapters
were greyed out. For your information I can confirm that the wifi switch on
the laptop body is switched to ‘on’ . I have also been through all the
settings in the BIOS looking for a Wifi option without success. When I
removed the USB adapter the narrative for that adapter remained greyed out
but changed to ‘Device Not Managed’… One of the other things I read and
tried was moving the switch on and off several times to see if it woke the
wifi net - no luck with that either. I also read and tried different power
settings in case the laptop was suspended - no luck again.

Open a terminal and enter:

sudo rfkill list all

and post results here.

Hi Dave_Barnes,

Here is the out put as requested;

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

I have checked in the BIOS, Moved the laptop case wifi switch several
times , tried rfkill unblock all,…nothing seems to change the Hard
Blocked output.

Regards.

Hi @matebod,

also take a look at @ouroumov’s answers here, maybe he can chime in on this one again as his commands seem to have solved that problem but I don’t know if the commands will do the same for your problem?. :smiley:

You will probably have to boot Windows and enable the wireless LAN device in “Network Settings” as there is an additional software controlled WLAN switch. You may also have to use the Intel PROset Wireless utility to enable the WLAN device.

See page 92 in this document:

Hi,

I have already tried to do what you have suggested - without any luck…
I have already downloaded the manual and looked at the wifi stuff…no
joy!

I have enabled and re-enabled the connection in XP’s network manager, I
have installed the Intel Proset Utility and it has reported that a
driver is not installed, so I had opened up the Device Manager and the
intel wifi dedvice looked fine (no re or yellow icons by it) - the Intel
utility still reports that a driver is not installed, which seems odd. I
have removed, installed and reinstalled the Intel 2100 b mini
driver…still no change. However as soon as I plug in the TL-WN725N
wifi adapter I have wifi connectivity with XP… sadly this is not the
case in Mate…- which reports that both the usb wifi and onboard
wifi are disabled.

As you have probably gathered I am somewhat confused by Mate, first time
in several years of use that I have had any issues with Ubuntu,and very
new to it all.

I have noticed that since installing Ubuntu Mate I have been getting
error messages when I boot:

[drm:intel_set_cpu_fifo_underrun_reporting [i915]] ERROR pipe A underrun

and

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] ERROR CPU pipe B FIFO
underrun

These two messages were highlighted in the output from ‘dmesg’ …
could it possibly have any

relevance.

I have ‘googled’ them but regrettably what I found didn’t really mean
much to me.

I regret my input is somewhat foggy but I’m trying hard!

Too prevent you using up too much precious time I will say that maybe
try one more suggestion then I will try to revert to using ubuntu 32 bit
with gnome metacity as that worked fine before (for over two years
without a hiccup!)

Best regards…

Hi @matebod,

try a different approach, with a network cable connection, start in recovery mode and run “dpkg” and then restart per the guide with “Ctrl + Alt + Del”, don’t click on resume!.
See if that helps at all?:

Hi there,

Many thanks for the suggestion…tried it a few times .

Also tried option of restarting network in recovery… a few times…
neither worked.

Thank you for your continued support but I think the time has come to
try my spare drive again and go for a completely fresh install as the
amount of time and effort spent on this has become burdensome…even
before I used the support forum I spent far too much time trying all the
solutions on the internet. My trusty old laptop will still be usable
with XP if all else fails…Why oh why did that company abandon
such a popular operating system?..

My very best seasonal regards to you for all your assistance.

Hi Dave_Barnes,

Thank you again… I have tried your suggestions…sadly I am unable to
report any progress.

I have decided to abandon this course of trouble shooting as even before
I placed my issues onto the forum I had spent a lot of time reading
about other peoples problems.

Going forward I will try to do a totally fresh install on a spare drive
and try that (…again…) In need I can always put my original drive
back and use my XP installation to get onto the internet…not ideal but
a solution / workaround.

Once again I really have appreciated your help / suggestions - thank you.

Regards

Iggy

Hi Iggy,

make sure you get the 16.04.1 release if you do a fresh install!:
