I'm sorry - this means nothing. Windows dosn't have to get through your linux firewall. RH9 comes with it's own firewall which may be preventing you from connecting to your lan. What does iptables -L say? Disable the firewall with /etc/init.d/iptables stop (I think...)

If you cannot install wlan_wep, then you cannot use wep encoded connections. how have you attempted to install this? How did you determine you needed to?

I'm sorry, I don't understand what you want to do. "undecode"? When you encryp something it is "encoded"... when you decrypt something, you "decode" it. To "undecode" suggests you want to undo the previous decode ... why not just encrypt it again?

Basically I don't think I can help you.
You do not follow suggestions.
You do not give feedback.

Please read the "advice" link in my sig before posting again.

I did thw post #10. However, the network still does not work.
This time I found that when I use
iwconfig wlan0 essid ESSIDNAME

I tested by [root#]iwconfig wlan0

wlan0 IEEE 802.11g ESSIDff/any
Mode:Managed Frequency:2.462 GHz Access Point: not associated

However, I can use iwlist wlan0 scan to find the ESSIDNAME.

This time, I removed the key of the router.

I had the same problem and I fixed it by doing the following:

1. sudo modprobe wlan-wep

2. I changed my /etc/network/interfaces file from this:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

iface wlan0 inet dhcp
wireless-essid <your essid here>
wireless-key <your key here>

** to this : **

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

iface wlan0 inet dhcp
wireless_keymode open
wireless_key <your key here>
wireless_mode managed
wireless_essid <your essid here>
auto wlan0


** Next thing I know, wham bam thank you ma'am it works. I'd love for someone to explain to me why.... Hope it works for you too.

I can not find this file. What's distro you are using?

The first time I installed wlan-wep, it said the "undecode command can not be found". I install shaurite packet, then this problem disappeared.

Currently, I have remove the key from my router, however, I still can not set the essid. (after I set essid by iwconfig wlan0 essid, and I used iwconfig to check, the essid is still off).

/etc/network/interfaces ? I don't have this either. The manpage "interfaces(5)" dosn't exist. This is a Debian thing. Fedora dosn't use it.

Can you see why it is important to edit your profile to show your distribution?

Are you sure that isn't "uudecode"?

And how were you trying to install wlan-wep?

Did you try "modprobe wlan-wep"? (post the command as you typed it and the result.)

You did what with post #10?

I'm sorry but you have yet to give any sign of having followed any of the instructions or suggestions I have given you. You didn't even edit your profile as requested.

Not all of the suggestions of things to try will be solutions in themselves - you must post the results here so I can figure out what is going on.

Yes. I see. thx.

I am sure it is undecode, not uudecode.
I tried. However, the wlan-wep can not work. Now, I removed the key and want to see the network works. Till now, it is not work.

I did the uninstall of ndiswrapper and the card driver, I also uninstall the wireless tools, which include iwlist, iwconfig. I reinstall all of them. The results are the same as above.

Current, I removed the key in the router. I think I just need set the essid and the network should be fine. However, it still does not work, since I can not set the essid by :
[root#]iwconfig wlan0 essid ESSID_NAME.

2 questions:

1- Did you check to see if your card is supported by ndiswrapper?

2- You're trying to install madwifi; is your card supported by that?

Yes. I checked. My card is supported by ndiswrapper and madwifi.

I have been having the same problem all over around!.

But the thing is that Iam actually able to associate wlan0 with the AP (Iam not using encription). Even though the card cannot ping any computer in the network, not even the AP.

Another quite courious thing is that it receives packets, but is not able to send.

RX bytes: 284857 TX Bytes: 0

And in iwconfig:

Tx excessive retries:34 Invalid misc:69

This is quite weird. I am going to kill this card tomorrow.
