i am a tyro on Ubuntu,i am not know how to solve the problem.could anybody help me to fix this? :(

[Ayuthia]

when i start my laptop,I always find the error message
Error:module b43 does not exist in /proc/module
Error:module b43ledge does not exist in /proc/module

This looks like you have a script that is trying to remove the b43 and b43legacy modules. By any chance did you add anything to /etc/rc.local or possibly /etc/init.d/wirefix.sh? If you are not sure, can you post the results of (from the Terminal):
grep b43 /etc/rc.local
grep b43 /etc/init.d/*.shThis will search through /etc/rc.local and the /etc/init.d/*.sh files to see if there is any information about b43 in them. If there is, that is most likely the file that is causing the problem.

By the way, is your wireless working?

[johnshentiro1]

yes,I add the following text into my wirelessfix.ssh
there are the content added in it:
#!/bin/bash
#this script unloads the ssb module so that it doesn't claim the Broadcom card

rmmod b43
rmmod b44
rmmod b43legacy
rmmod ssb
rmmod ndiswrapper
modprobe ndiswrapper
ifconfig wlan0 up

================================================== ======================
here is the result :

john@ubuntu:~$ grep b43 /etc/rc.local
john@ubuntu:~$ grep b43 /etc/init.d/*.sh
/etc/init.d/wifi-fix.sh:rmmod b43
/etc/init.d/wifi-fix.sh:rmmod b43legacy
/etc/init.d/wirelessfix.sh:modprobe -r b43
/etc/init.d/wirelessfix.sh:modprobe -r b43legacy

thanks,what is to do next?

[johnshentiro1]

By the way, is your wireless working?

By now,I still not find some way to solve the problem. while there is no error appears,could you help me fire this problem?

oh,thanks for your reply.

[Ayuthia]

Error:module b43ledge does not exist in /proc/module

Is this a misprint? Was it supposed to say b43legacy?

The error message that you are seeing is because the b43 and b43legacy modules are not loaded. Since it is not there, rmmod shows this message.

However, the wirelessfix.sh is causing the problem with your wl driver that you are trying to use. It is loading the ndiswrapper module which will conflict with the wl module.

john@ubuntu:~$ grep b43 /etc/rc.local
john@ubuntu:~$ grep b43 /etc/init.d/*.sh
/etc/init.d/wifi-fix.sh:rmmod b43
/etc/init.d/wifi-fix.sh:rmmod b43legacy
/etc/init.d/wirelessfix.sh:modprobe -r b43
/etc/init.d/wirelessfix.sh:modprobe -r b43legacyThis shows that you have two files (wifi-fix.sh and wirelessfix.sh) that are trying to do something for your wireless card. I would recommend commenting out the lines in those two files for now because if you want to use the wl driver, those two files will cause problems.

To see if you wl module works, you can try the following (will only work for the current session):
sudo modprobe -r b43 b43legacy b44 ssb ndiswrapper
sudo modprobe wlIt might take a few seconds for network manager to see the wireless module change.

[johnshentiro1]

as you metioned,I comment out the two line in wifi-fix.sh and wirelessfix.sh
there is the result:

john@ubuntu:/etc/init.d$ less wifi-fix.sh
#!/bin/bash
#this script unloads the ssb module so that it doesn't claim the Broadcom card

#rmmod b43
rmmod b44
#rmmod b43legacy
rmmod ssb
rmmod ndiswrapper
modprobe ndiswrapper
ifconfig wlan0 up
ESC

john@ubuntu:/etc/init.d$ less wirelessfix.sh
#!/bin/bash
#modprobe -r b44
#modprobe -r b43
#modprobe -r b43legacy
#modprobe -r ssb
modprobe -r ndiswrapper
modprobe ndiswrapper
modprobe b44

But what confuse me is can I remove the wirelessfix.sh?
I removed the wirelessfix.sh.Is that right?

and when i login after remove the wirelessfix.sh and press ctrl+alt+F1.There is all the error message.
is There something wrong?could you help me to clear this?

what's next step?

[Idefix82]

Please follow Ayuthia's advice:
sudo modprobe -r b43 b43legacy b44 ssb ndiswrapper
sudo modprobe wl
sudo ifup eth1
sudo iwlist eth1 scan

and see if you get connected. Let us know, before you do anything else. If this works then all you will need to do is make sure that ndiswrapper is not interfering with your wireless driver. If it doesn't work then we will have to try the ndiswrapper way.

[johnshentiro1]

Please follow Ayuthia's advice:
sudo modprobe -r b43 b43legacy b44 ssb ndiswrapper
sudo modprobe wl
sudo ifup eth1
sudo iwlist eth1 scan


yes,I follow it,I can see the connection,but I can not get connect.there is the result
================================================== ================

pls help me!I don't like get connect only with my wired network

[Ayuthia]

I forgot to have you clear out the wl module also. Please try the following:
sudo modprobe -r b43 b44 b43legacy ssb ndiswrapper wl bcm43xx
sudo modprobe wl
sudo ifconfig eth1 up
sudo iwlist scan

EDIT:
If it still does not work, please post the results of lshw -C network.

[johnshentiro1]

Thanks,Ayuthia.
I do what you tell me ,but it still can not work,Ooops!
here is the result:

how can i do next step?

[Ayuthia]

It looks like your card is able to see wireless sites now. The next step is to see if you can connect. I don't have too much experience with WPA so I am not going to be able to help you too much there.

The next step that you should try to do is turn off your encryption and see if you can connect to the router. I am guessing that yours has WPA on it because of the signal strength (Siloon_Linksys shows a signal strength of 5/5). If you are able to connect, you will then need to figure out how to connect using WPA. Also, if you are able to connect, you might want to get the system updated so that you can have the most up-to-date version of your wireless driver.
