Can you give the output of:

sudo lshw -C network; sudo iwlist scan | head -n 20

Thanks

I am sorry I have no idea what that means....

Press CTRL+ALT+T
paste or ACCURATELY type the command exactly how it is written and hit ENTER
copy the ouutput and paste it here (or type it out accurately)

kris@kris-desktop:~$ sudo lshw -c network

When I tried the other command it says the network does not allow scans

kris@kris-desktop:~$ sudo iwlist scan | head -n 20
lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

Thank you for being patient with me...

It's cool. Ok your wireless is not detetcted. ok, reboot with the device detatched, log in and get the OS ettled and run:

lsusb

then plug in the device, wait 10 seconds then run:

dmesg | tail; lsusb

Copy the whole output and paste here as an update

Thanks

ok you need the file: rtl8192sfw.bin

As you can see it is missing.

you need to run:

sudo apt-get install linux-firmware

and you will get the file. Repeat the process of rebooting and the commands, it should be better. If all is well run:

sudo iwlist scan

Does it pickup access points?

Please first follow actionparsnip's advice.

If actionparsnip's advice is not enough to solve the issue, please also try all the suggestions (one by one) in the following bugreport:

Thank you all, I will try once I get home. If it works or not I will post results or ask for further help.

Scan is still saying that interface does not support scanning + I tried the link above and entered the symlink but I am not sure if I did it right result = command not found.

Success now how do I get it to work??? Sorry I am such a NEWBIE....

read the words. They are exact instructions. You clearly aren't a newbie at reading.

Nice, thank you. I apologize for being new Ubuntu and for the frustration I have caused you.

Thanks Mark Rijckenberg, that solved my question.
