View Full Version : [ubuntu] Where do I store wireless network settings so they load on boot.

I upgraded to Ubuntu 9.04, One of several problems is that the wireless network connects at 1 mb/s.

I have found information about setting the speed:

sudo iwconfig wlan0 rate 54M

This works fine, however it does not hold. When I reboot, the setting goes back to 1 mb/s.

I just know there is a place where I can make these settings permanent.

In older versions, /etc/network/interfaces would have been the place (maybe still is?) but the "new" Network Manager is a different kind of animal to deal with.

All I can think of at the moment is to add the line,

iwconfig wlan0 rate 54M

to the end of the file /etc/rc.local

(do this by running the command 'gksudo gedit /etc/rc.local')

This isn't the most elegant of solutions, and I'm sure someone could come up with a better solution. Basically rc.local is a script which runs at boot with root privileges (hence leaving out the sudo).

What wireless card do you have?

I checked that file but there are only two lines in that file. So i am not clear where or how it should be entered.


That did the trick.... I put that line in the rc.local file, rebooted and It came up at 54 MB/s!!

I'll wait to hear if anyone has another fix, but until now this fix is it.

Thank you both for you help.
