Forget about the tape trick as you must have got the hard block cleared without it, post

Code: Select all

lshw -c net; ifconfig; iwlist scan

Please check the antenna connection on the wifi card and there might be 2 antenna connectors but those results show it is functioning but has no scan results and that could be caused by disconnected antenna(s)

Can you use the Update Manager through View/Linux Kernels to update to the 4.4.0 series, then reboot and see if wifi works

This is a big step..I have changed kernels before, so i know how to do it, but keep reading scare stories about not being able to boot the laptop up afterwards. If that happened, would i be able to put the live disc back in and load a new os?

Also the current kernal 3.19.32 has been in all the time and until a few days ago the wi fi worked well, so could the kernel really be the problem here?

There is very little to be concerned about when using the Update Manager > View menu to install a different kernel.
If you don't like the new kernel, the old one is still installed. Switch to the old kernel in the Grub menu when you boot.

I believe that anytime you have 2 kernels installed, or 2 OS's, the Grub menu will show up.
If not, open the file /etc/default/grub in your text editor:

Code: Select all

gksudo pluma  /etc/default/grub
and add the line:

Code: Select all

GRUB_TIMEOUT_STYLE="menu" 
Save the file and exit the editor, and update Grub:

Code: Select all

sudo update-grub

Unfortunately you may be correct. I can't find anything else wrong in the wireless-info.txt file you pasted. It may be a case where the wireless card needs to be removed and reinstalled, possibly a connection issue with the motherboard

Since i last posted, a few interesting things have occured
After doing rfkill list the other night and saw the system was soft blocked i did "rfkill unblock wifi" & i got the wifi options back. I selected my own broadband, put in the password, and it worked

I shut the system down later, and the next morning i booted up, & wi fi was still working

Today when i booted up, there was a loud noise, and a page that told me time and date had been corrupted, and hit F1 to continue. I did and the lap top booted up, but the time showing was 1.01am and the date showing was 1st Sept 2007. I turned it off, and went into the bios to change the time and date to how it was at the time

when it booted up again, the wifi wasnt showing options once again. I did the rfkill liss command, and it showed me it was hard blocked

I tried
rmmod -f iwlwifi

rfkill unblock all

modprobe iwlwif

but it didnt work...then i tried

sudo rmmod -f ath5k

sudo rfkill unblock all

sudo modprobe ath5k

and this did work....it connected back to wifi

I havent turned the laptop off since that, and the wifi is still working.
I wish i could prevent it hard or soft blocking in the first place

It sure sounds like that cmos battery needs to be replaced or reseated.
