Update 1: Chris (see comments) has kindly provided a up-to-date driver (from Realtek) said to fix hanging issues after hibernate. I tested hibernate and
apart from an Ubuntu One crash it worked. Instructions from the Realtek contact are provided below the original post, if you find it doesn’t work and want to try a different method.
Update 2: I’ve had to take the Realtek rtl8192e driver file down now as it’s hammering my bandwidth and I don’t want to pay extra money at this time. However I uploaded a copy to YourFileLink file hosting – get it here.
Update 3: For those who have upgraded to UNR version 10.04 and above, this solution seems to no longer work, please see my updated post.
My Sammy NC10 worked flawlessly when I installed Ubuntu Jaunty and every upgrade after then, before that, on Ibex I had to do teeny bit of hacking to get the wireless to work.
Well, after purchasing my N210, wireless is once again broken of course. Must be something to do with Samsung’s choice of wireless cards. Thankfully help is always on hand and I found the troubleshooting post at the Ubuntu Forums.
Now follow the instructions below (reproduced from chilli555′s forum post):
- Open a terminal and type:
sudo apt-get install linux-headers-`uname -r` build-essential
- Extract the downloaded file to your desktop and then cd into the newly created directory (rtl8…)
- Now do type the following in order:
- You may find you need to run the 2nd from last command (modprobe) as a normal user in order for wireless to start up automatically next time to reboot.
It’s as simple as that, and if your wireless fails again after a major update, then just run the modprobe command again. But it’s best to save the driver locally somewhere just in case.
For the NC10, Canonical fixed this issue on the next release (Jaunty) so I have faith that this will be a none issue in less than 6 months time also.
Alternative install, provided by Realtek:
1. Change to the driver directory.
2. sudo su
4. make install
6. ./wlan0up or ./wlan1up
Notes: 1. If permission denied, change property with `chmod 777 wlan0up`
2. Or enable driver with `ifconfig wlanx up`(wlanx denote wlan interface name).
