iwlist unable to scan for available networks


Hi,

I am a newbie to Linux. I have installed fc3 on a Acer Inspire 5002 machine.I decided to try wireless. I have a inbuilt Wireless card ( Broadcom). I installed ndiswrapper following the instructions given in the ndiswrapper homepage. The installation was smooth. I even got the connection established once. But then I again rebooted and thats when the trouble started.

"iwlist wlan0 scan" has stopped showing any networks in the vicinity. However the SSID broadcast in the router is turned on and I am able to view the networks in Win XP. Also Previously it did show me all the networks in the vicinity before the reboot. So I am sure there is no problem with the router. Also the ndiswrapper module is loaded and I do not have WEP configured in the network.


Any guess what the problem might be ? If you require more details then please let me know with instructions on how to get them ( i am linux idiot!!!!).

Thanks
CK

I tried to set the essid for the network using "iwconfig wlan0 essid "myssid"
But this wont work. Then when I try to scan for the list of available networks it didnt show me anything.

Thanks
CK

If you type iwconfig it shows you that the wlan0 is active?

Show us the output from the following commands;

/usr/sbin/ndiswrapper -l

cat /proc/modules | grep ndiswrapper

iwconfig

Hi

First of all sry for the delaying the reply. I somehow got the internet going without encryption.I didnt do anything. I just rebooted it yesterday night and it started working, wierd !!!. I have just one more problem. When I reboot the WEP key is not getting set.I tried all possible combinations for setting the key in the /etc/sysConfig/network-scripts/ifcfg-wlan0.KEY = "open blahblah" / "blahblah" / blahblah /"blahblah open" etc.. ( I am running fc3) but it wont take the key and the network card fails to get activated...But if I turn off the WEP and then reboot then everything is fine and I am able to connect to the internet.
Any clues as to how to overcome this ?

Thanks
CK

Try using the system-config-network utility instead of editing the keys file yourself. Make sure both your router and wireless device are using the same key(s) and encryption. If the wireless router is not using keys then your key file should be empty also.

My key files are found in /etc/sysconfig/networking/profiles/default
