I am using mint 17.3 64bit mate.
My Laptop (Samsung R60 plus) - I normally connect to the internet via a cable connection so was surprised when I took the laptop to a conference and found the wi-fi adaptor was not recognised by the system.
I presume this is a driver issue how do we address the problem?
Thank you in advance.
What’s the output from:
lspci -vnn | grep -i net
and
lsusb
and
sudo lshw -C network
and
rfkill list
and
ifconfig
and
iwconfig
and
iwlist scan
Have just noticed the WiFi indicator light is not on.

does running:

then
sudo modprobe ath5k nohwcrypt=1 no_hw_rfkill_switch=1
kick wireless into life ?
if not, is there any output from:

Wi-fi still not working.
Read out -

Also found the following file on the system - blacklist-ath_pci.conf /etc/modprobe.d this has the following content -
blacklist ath_pci
Is this having an impact?
Can you REBOOT then post the output from:
dmesg | grep ath5k
again.
and the output from
lsmod
Ignore if you’ve already tried this -
Hitting Fn key then F9 toggles the W LAN on this model. If the indicator led lights up, click on Network Manager and check if everything looks correct in there - there are options to ‘always connect to this network’ etc.
Plus, there’s a manual available from - Support for NP-R60 SAMSUNG
Hope this helps

Does running:
sudo rfkill unblock all
make any difference ?
No difference still no Wi-fi.
I have noticed that the use of a programme called JOCKEY is recommended as an answer to this issue.
I have downloaded the software from Jockey (Linux) Download: Driver manager.
In case this is a viable option.
It’s not a problem with madwifi, the madwifi driver ceased to exist in 2007 and was superseded by ath5k and ath9k.
As I’m not really seeing a problem other than your wireless not seeing any networks, are you sure
a) the antenna lead hasn’t come off the adapter
and/or
b) your router isn’t broadcasting in say the 5GHz band which the adapter doesn’t support ?
I used an old D-Link USB wi-fi DWL-G122 802.11g adaptor and that works fine.
I will see if I can find out where the antenna lead is located and take a look-see… removed the wi-fi card cleaned all contacts reinstalled and attached antenna cable.
After a lot of reading on the net I found a BIAS setting to switch on wi-fi permanently the wi-fi light is now on but still not scanning for wi-fi networks…
So now here is the readings from your first post with the adaptor switched on…

I think this was resolved once I found the setting in the BIAS as it would seem that the problem is the wi-fi adaptor in that just by chance I moved the laptop into the same room as the modem and hay-presto I had a wi-fi signal.
Strange that it is just this lap-top that is not getting a signal and thanks for all your help.
Which could mean the antenna has come off the wireless adapter 
Of course it could also mean the adapter is just rubbish.
I have checked and rechecked the antenna cleaned the socket it is a push fit and tested with a multi-meter that the circuit is complete and all OK.
So it seems that the adapter is just rubbish as you said so have ordered a new up-to-date usb unit that is Linux compatible.
In that case, you probably did the right thing
