My screen brightness is very high, i am unable to change it using FN keys. Please help.

For your wireless device, download this file to your desktop: http://dl.dropbox.com/u/57056576/DRI...14.2012.tar.gz

Right-click it and select 'Extract Here.' Now open a terminal and do:

cd Desktop/rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012
sudo su
make
make install
modprobe rt8723e
exit

On my 12.10 system, it compiles with a couple of harmless looking warnings. I can't test further because I don't have the device. Post back if you get stuck.

I don't know much about your display issue; you might ask here: http://ubuntuforums.org/forumdisplay.php?f=331

Chili,

I have downloaded the package and getting the below error while installing it.

BTW, brightness is resolved now after running a complete update.

Interesting. The original file I linked makes on 3.5.0-24 but not -25. Please try this instead; it makes, albeit with a few more warnings: http://www.liteon.com/UserFiles/driv...09.2012.tar.gz

Chili,

I have tried the above mentioned driver. I have successfully executed the steps mentioned, but getting the below error in the last command.

root@vel-Satellite-C850:/media/E47478CF7478A5C8/new/rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012# modprobe rt8723e

Please help. Also please let me know how do you find the exact driver for WLAN??

Then there was an error further up in the compile process. Are you trying to make and install this from a USB key or CD? I believe you need to drag and drop this to your desktop. Please try again.

Also please let me know how do you find the exact driver for WLAN??

I don't exactly understand. Do you mean how do I find out what to install from the details you've given me?

I did copy it to the local hard disk and compiled it from there. I will give it a try and post the results.

I don't exactly understand. Do you mean how do I find out what to install from the details you've given me?

Yes, I mean how do you find out what driver to install from the details i have given.

[chili555]

Yes, I mean how do you find out what driver to install from the details i have given.

You're asking me to reveal my secrets? Now everyone is going to see how easy it is. If you insist, here goes.

First, the device ID is everything. Find out with:

lspci -nn

Or, if it's a USB device:

lsusb

Here is an example from my machine:

03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6200 [8086:4239] (rev 35)

Next, I search Google for the ID numbers. I see this,for example: http://wiki.debian.org/iwlwifi

PCI: 8086:4239 Intel Corporation Centrino Advanced-N 6200

This same process, for any networking device, wireless or ethernet, works the same.

Some devices are covered by a driver in a later Ubuntu version, but not an earlier. We can tell if a device is covered with modinfo:

chili@Think410:~$ modinfo iwlwifi | grep 4239
alias:          pci:v00008086d00004239sv*sd00001316bc*sc*i*
alias:          pci:v00008086d00004239sv*sd00001311bc*sc*i*

So we can see that this device is covered by iwlwifi in my Ubuntu version, 12.10. Of course, a few years of experience means I recognize many devices immediately without Googling.

In order to test whether the device is covered in earlier versions, I use live CDs for 12.04 and 10.04, etc. I can start up the live CD, compile a driver, etc. and give informed replies in a wide variety of cases.

My favorite cases are the ones where I Google and the first hit includes 'chili555' and 'Solved!'

I look forward to your compile results.

Thanks for revealing your secrets Chili. It was very well explained and organized. As a linux beginner, i would say it is still pain find the drivers(especially for linux) and have them installed successfully. I will continue to explore my knowledge and try to gain to more knowledge in linux (somehow i love linux).

My favorite cases are the ones where I Google and the first hit includes 'chili555' and 'Solved!'

That's awesome to hear

I look forward to your compile results.

Hurray i just boot my laptop, it figured out my wireless connection and gave me an alert. I was surprised and happy. Now i am sending this message through my wifi connection. Thanks a lot for all your help. However i have USB modem, i hope i will find a driver for that using your above method and have it configured. If i am unable to do so, i will post here and disturb you again!!

[chili555]

Glad it's working! Please feel free to post back if I can help you at any time.
