Internet Connection Failure

[jery_wang]

I have a problem with my internet connection. I just recently configured my Linksys router with a "WEP" key and secured it on Windows XP. Here is what I did:

1. I opened up my web browser and typed in 192.168.1.1
2. Typed in username and password and logged in.
3. Went to wireless settings and gave it a WEP key.
4. Saved it and I exit out of browser.
5. Went to my wireless configurations and saw that it was secured and had a WEP key which is what I want. Internet seems ok.

Everything seems to be working fine on Windows after I configured it. But when I boot to Fedora Core 4, I can't connect to the net. I know that the configuration some how had an affect. Anyway, I normally would type in "/sbin/ifup wlan0" in terminal to activate the internet but it doesn't work this time. It gave me the following error:

"Determining IP information for wlan0.....failed"

I don't know what to do or where to begin to fix this. I have a Linksys router and I use Netgear MA111.

You have to set up Linux to use the WEP key as well. Without the
proper key, your router is not giving you DHCP information.
Basically, it is not letting you on the network. I am not sure what
the wireless setups tools are on FC4, but if nothing else, you can
use iwconfig to get your interface up and running, at least until
you reboot, or someone tells you the correct tool to use on FC4.

When I typed in /sbin/iwconfig I get the following.

I read the man page of iwconfig but there wasn’t much I could do. I read about “key/enc” which sort of gave me a hint and thought if I could type something like the below………

/sbin/iwconfig wlan0 key <my key>

^ I thought that if I typed the above in terminal I would get a connection, but no luck, again not sure what I’m doing. You said from the above that I also needed a WEP key for FC4 and that’s what I thought too. But I don’t know how to do that. I’m currently googling on how to setup a network WEP key, I just hope something turns up.

Just want to let you all know that it's fixed and don't bother with this post anymore. I found the solution to my problem. It's quite simple actually, I just didn't look harder from the beginning and that was my problem. Here is what I did to fix it.

I went to Desktop>System Settings>Network and highlighted "wlan0" and clicked on edit. Then I went to wireless settings and entered the WEP Key.

The command......
> /etc/sysconfig/network-scripts/key-wlan0

The above command showed me "Key=......." meaning I had no key. I knew something was fishy.
But anyway, earlier I could've fix it without the gui. I made the mistake of typing.....
> /sbin/iwconfig wlan0 key <my key>

instead of......
> /sbin/iwconfig wlan0 key restricted <my key>

But anyway, it's all fixed now and I'm happy :)
