I have performed sudo apt-get dist upgrade and have updated drivers through Ubuntu but all to no avail.

Here is the output of dpkg -S rtl* | grep /lib/modules/$(uname -r)/kernel/drivers/net/ as requested in the comments:

The below answer is copied from my answer here. However, the person still has not marked it as the correct answer.

Okay, we'll have to manually download the driver for your wireless card and install it.

Step 1

Download this, and save it to your Downloads folder

Step 2

Open up a terminal. To do so, hit Ctrl+Alt+T. Type in the following commands and hit enter, one by one.

cd ~/Downloads
unzip rtl*
cd rtl*

Step 3

Enter the following:

sudo make

If the output from this command gives you lines that mention an error, like this:

make[1]: ***[_module_/home/alaa/Downloads/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012] Error 2 
make[1]: Leaving directory/usr/src/linux-headers-3.8.0-19-generic'
make: * [all] Error 2

...then stop here, and let us know. But if it does not give you lines that contain the word "error", type the following command:

sudo make install

Step 4

Once that is done, enter the following command:

sudo modprobe rtl8192se

You should not get any output here (if you do, just ignore it). Check if your wireless is working. If it isn't, reboot your computer.

have done all this and no joy im afraid – user157978 May 12 '13 at 12:08
The newer version of the file is recommended. Here is a link from my Dropbox. https://dl.dropboxusercontent.com/u/58267392/rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012.tar.gz Please try again. – chili555 May 12 '13 at 12:28
Hi my son, who knows what he is doing hsa been dealing with this but has now gone. i am a complete novice. can you please guide me through what i have to do with this info. thanks – user157978 May 12 '13 at 12:54
Follow the steps in my answer. Also, the file mentioned in my answer is a modified one that should work. Or, you can use the file mentioned in the comment by @chili555. – Alaa Ali May 12 '13 at 14:05
HI have tried again, no error messages but still does not find any wireless networks – user157978 May 12 '13 at 16:53
That's odd. You rebooted, right? Can you edit your question to include the output of the following command: lsmod | grep rtl. – Alaa Ali May 12 '13 at 17:14
And also, the output of this command: dpkg -S rtl* | grep /lib/modules/$(uname -r)/kernel/drivers/net/. – Alaa Ali May 12 '13 at 17:28
yes re booted do i just type lsmod grep rtl into terminal? – user157978 May 12 '13 at 17:43
have managed to do second one – user157978 May 12 '13 at 17:50
It's lsmod | grep rtl. The symbol after lsmod is Shift+\ (shift backslash), usually next to the Enter key. – Alaa Ali May 12 '13 at 17:53
nothing happens when i input this??? – user157978 May 12 '13 at 18:08
Okay. Try the command sudo modprobe rtl8192se, and enter your password when asked. You shouldn't see any output. If you do, tell us what it is. If you don't, check if your wireless is working (also check if it still says UNCLAIMED in sudo lshw -C network). Also, in your previous comment you said "doesn't find any wireless networks"? Do you mean that it's working but it can't find WiFi networks? Or did you mean the wireless card is not working, and is still showing "UNCLAIMED" as in your original question? – Alaa Ali May 12 '13 at 18:15
wireless not working . it does not even try to search for networks although previously used ones are showing. it does not say unclaimed but PCI (sysfs) if you run your command????? – user157978 May 12 '13 at 18:30
No just give the command some time, it will show the output. Anyways, I think I have found the problem. Delete the files and folders that you downloaded in your Downloads folder (everything that start with "rtl"). Download the file that @chili555 posted (in the second comment here) to your Downloads folder. Follow the steps in my answer (Step 1 to Step 4), and hopefully it should work. – Alaa Ali May 12 '13 at 19:06
If, in the end, it does not work, show us the output of dmesg | grep 819. – Alaa Ali May 12 '13 at 19:29
have downloaded chili555 file. says its not a zip file. the command cd rtl* does not work either??? – user157978 May 12 '13 at 20:29
Download the file to your desktop. Right-click it and select 'Extract Here.' It will extract it no matter what it is. Then do: cd Desktop/rtl* and continue on as above. – chili555 May 12 '13 at 23:38
Oops. Sorry, my bad, chili's file is a different format. You could follow what chili said, or replace the command unzip rtl* in my answer with tar -xzf rtl* and continue. Also, since this discussion is turning into a long one, there is one solution, though I don't know if it's fine with you: upgrade to Ubuntu 13.04. This latest version of Ubuntu already supports this driver without installing any extra stuff (correct me if I'm wrong @chili555), so it should directly work if you upgrade to 13.04. – Alaa Ali May 13 '13 at 05:07
Quite correct. You may or may not need to install extra firmware, a quite easy task. – chili555 May 13 '13 at 12:43
is the fact that 13.04 is unsupported gong to be a problem – user157978 May 13 '13 at 17:08
No no. Ubuntu 13.04 is not "unsupported", it is supported for 9 months. Every Ubuntu version is supported. LTS (long term support) versions, which come out every two years, provide 5 years of support, instead of the usual 9 months. This "support" basically means security enhancements, compatibility with new hardware, and so on. In my opinion, it is more for people that use Ubuntu to run servers (for example, run a website). But the average user should not worry about this, you will not be getting anything "less" from the normal versions. – Alaa Ali May 13 '13 at 17:29
Can you move this to chat? – RolandiXor May 14 '13 at 15:20
I tried, but the user has less than 20 reputation. – Alaa Ali May 14 '13 at 16:15
