howto: get wireless working on samsung n130 - realtek 8192

[ssam]

this should work on any machine with a realtek 8192 or 8192e card

karmic does not contain a driver for the realtek 8192 wireless card. there are already several posts that show how to download the driver source, compile and install it.

however the kernel in lucid (ubuntu 10.04) has the driver built in. it is possible to run the lucid kernel in karmic. this safer because it saves you from having to download packages of unknown origin, and run untrusted scripts (all the other howtos require this).

first you need to install the lucid kernel. the latest version can be found at https://launchpad.net/ubuntu/lucid/+source/linux you want the linux-image-2.6.32-10-generic binary package for either i386 (32bit) or amd64

i got mine from a mirror http://fr.archive.ubuntu.com/ubuntu/...10.14_i386.deb

2.6.32 has been out for a few months, so you should find it just as stable as the karmic kernel. if lucid switches to 2.6.33 by the time you read this, then you may want to hunt out the older 2.6.32 version.

now download that deb, double click it, and install.

now one more step,
currently the ubuntu lucid kernel does not contain the firmware for the card. this will hopefully be fixed soon, see
https://bugs.launchpad.net/ubuntu/+s...ux/+bug/508746
if the bug is not marked as fixed, then you will need to grab the firmware from kernel.org

sudo apt-get install git-core
cd /tmp
git clone git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/firmware.git
sudo cp -av firmware/RTL8192E /lib/firmware/

now reboot and enjoy your wireless

greatly thank you for the heads up on this situation

Thanks for this! Am running Ubuntu Lucid on a Sumsung R580 which has one of these WiFi cards. Obtained and copied the firmware as described and now I can connect to WiFi networks (including WPA2 encrypted ones).

Thanks, I'm almost there now!

N130 with a persistant USB (made from Windows with LiLi) of the live netbook version -
lucid-netbook-i386.iso - with MD5 correct. We did that git jiggerypokery and all went well.

Now I get a wlan0 section from ifconfig (didn't before) and clicking on the networks icon shows a load of Wifi networks it can see. I probably haven't got the hang of it yet - it seems to be connected, but the update manager says it hasn't got a connection and web browsing doesn't work. The connections then disconnect within a minute or two.

What do we try next?

EDIT - UPDATE:
Might have been just bad luck - I tried with another distro using the NDISWRAPPER method (and Wireless_LAN_Realtek_1678.0.1019.2009.zip unzipped into a wifi folder in the home folder) and that didn't work either - despite being near what I believed to be an open hotspot. But I did have luck later on in a different location with that method...... and didn't have the Ubuntu 10.04 USB key with me at that point.

Before I try, does this also work on a RTL 8192SE?

The 8192SE looks to be much easier to work with than the 8192E- do a forum search here for "Realtek 8192SE" and you should find several threads (I have posted some info on a few of them). Forum member "Chili555" had a method that worked pretty well for a few people.

You could also try downloading the 8192SE UNIX/LINUX driver directly from Realtek's website:

http://www.realtek.com.tw/downloads/...Downloads=true

The 3rd section is labeled "8192SE" and the filename that I saw was "rtl8192se_linux_2.6.0013.1204.2009.tar.gz"

Hope this helps.

Edit: For the 8192E, it is worth reading this thread too:

Edit2: Here is a link that should get you on the right path for that 8192SE, knakworst:
