Wireless problems with Lenovo 3000 N100

[primitivling]

Hey everybody! I have a problem with the wireless on my Lenovo 3000 N100 (it doesn't even find any of the networks). It used to work fine and stopped working after I updated to Ubuntu 10.04. I fixed it back then (but unfortunately don't remember how). I recently kicked off everything and installed Ubuntu 10.10 and (I guess as could be expected) the wireless doesn't work once again. I am pretty bad with Ubuntu/ the terminal but managed to type in these two commands that people requested for diagnosis in another thread:

lsmod|grep -i -e b43 -e b43legacy -e ssb -e b44 -e ndiswrapper did not return anything but went straight to the next line..


Does anyone have an idea what the problem is/ how to fix it (in beginner language)? I'd be very grateful if you had some suggestions how to fix my wireless.

Oh, also my ethernet outlet has been broken for a while (something mechanical, i think), so updating and stuff would be a little bit difficult. I have other computers around though and could download something that i could transfer with a usb.

Hi, if you have not installed any other driver this should work the first time, if you have we will have to do some ninja moves on it.

Download the b43 zip file to the flash drive then drag and drop the file to your ubuntu desktop. Right-click it and select Extract Here. Open a terminal and do:

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/*  /lib/firmware/b43
sudo rmmod -f b43
sudo rmmod -f ssb
sudo modprobe b43

one line at a time, and it should come on.
Thank you

i have some trouble with the second line. It says cp: cannot stat `desktop/b43/*': no such file or directory.

was i supposed to fill something in for the *?

thanks and cheers (:

Hi, just copy and past the command one line at a time, do not type them.

Did you download the zip file and drag it and extract it to the desktop?
Thank you

Thanks wildmanne!

somehow i think the commands worked this time and immediately after typing in the last one the wireless networks appeared. There was however a Warning after typing the last command (see screenshot).

It also doesn't seem like all problems have been resolved. One thing is that I can connect to my wireless but when I try to use this client of my college to connect with firefox it says that there is no configuration for my device (see screenshot).

The second thing is that as soon as I restart my computer (or close the lid) the wireless stops working again. It works again if I reenter that last modprobe command (the warning appears again). is there no permanent fixup to this problem? I was thinking that maybe something didn't go right because I got that warning..

what do you think?

thanks and cheers (:

Hi, the first one I know nothing about it has to do with your college and they tend to try to force people to use windows.

To make it work at boot since it is not doing it already run this command and then reboot.

sudo su 
echo b43 >> /etc/modules 
exit

This is all one command.
Thank you

Hi,
I installed XBMCUBUNTU and have the same problem - NO WIRELESS NETWORK (WIFI dont work...)
Can I do this fix by running the ubuntu desktop from a cd?
and if not, how can i fix it in an xbmcbuntu operatin system??
THANKS!!

Hi, copy and paste this command in the terminal (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks
