Hi folks,

I am a newbie to wireless networking and I would like to seek help. Hopefully I can set up my wireless network successfully.

Here is the situation.
I bought a Linksys WRT54G router and WUSB54G USB reciever. I set up the device and test successfully in windowz (WTF?!). And then I boot into linux, downloaded and compiled ndiswrapper 1.1 (1.3rc1) and wpa_supplicant 0.3.9. Nothing is wrong up till now, i go to modprobe ndiswrapper as root. installed the USB reciever driver for windows using command ndiswrapper -i <path to driver>. ndiswrapper -l show everything is ready. But when I dhcpcd wlan0, it hangs there. nothing is shown until I send Ctrl-C to xterm.

tsun@killa:~$ sudo /sbin/modprobe ndiswrapper

tsun@killa:~$ /usr/sbin/ndiswrapper -l

Installed ndis drivers:

rt2500usb driver present, hardware present


tsun@killa:~$ sudo /sbin/iwlist scanning

lo Interface doesn't support scanning.



eth0 Interface doesn't support scanning.

I tried 2.4.31 stock kernel, 2.6.13.2 and 2.6.12.6 vanilla self-made kernels on Slackware 10.2.
No luck.

Anyone can figure it out?

Thanks.

I see that you're trying to set a WEP key using "iwconfig wlan0 key asas" and that command fails. A WEP key can be entered as a sequence of HEX characters (0123456789abcdef are the only possible choices then) or as a string of ASCII characters (i.e. a normal word). You are trying to set an ascii string "asas" as the WEP key. You will need to change the command a little to
If the WEP key setting is wrong, your card will not associate with the Access Point, and it will never get an IP address through DHCP.
By the way, you can add a timeout parameter to the dhcpcd command, so that you will get the command prompt back after 10 seconds if no IP address can be obtained:
Good luck,
Eric

Hi Eric,

Thanks for your reply, but I am using WPA Personal with AES as the WPA algorithm, so I could not get the wireless card running using WEP.

So how can I get it running using WPA?

Thanks.

Ah yes, WPA... then you should not try "iwconfig wlan0 key ...." since that is for WEP only.

WPA support is possible in Slackware 10.2 when you install wpa_supplicant.
I have an article up on the Madwifi Wiki which shows just how to configure and use WPA. That section of the wiki is not madwifi-specific and should be applicable to your ndiswrapper setup (I used ndiswrapper with WPA successfully on my workstation).

If it won't work at first, try the debugging techniques at the end of that Wiki section. I had to upgrade to the latest beta of wireless-tools to get WPA working with madwifi, you might need that too. See my slackbuild site for a newer wireless-tools package. You'll find a newer (CVS) version of wpa_supplicant too, on that site.

Eric

I have disabled the encryption function in the router so that I could hopefully connect to my router in linux box, but still no avail.

still cannot get an IP from router either using dhcpcd or ifconfig
wlan0 <ip addr> up.

The receiver functions properly since it can scan the network.

i have used following commands:
iwconfig wlan0 essid homenet_w
iwconfig wlan0 channel 6
iwconfig wlan0 mode managed


Anyone can figure it out?

As root All that does is make sure wlan is awake, associate it with the named network and then tell it to get a new dhcp IP. You do not need to set the channel by hand or the mode as the card should follow the AP settings.

Wonder why yours is using wlanx when all my Slack boxes use ethx?

That essid with an underscore might be a mistake....reports are that odd characters make life difficult..maybe just use 'network' or 'homenetw'

Finally success. I turned out that it was my configuration error on my wpa_supplicant.

No more than one interface could be set in the MakeFile else you would come to a situation like mine.


Anyone who need a detailed step-by-step on configurating LinkSys WUSB54G + WRT54G on slackware 10.2.
Just drop me an email or whatever to tell me.
