Wireless Noob!!! Loosing faith on Linux!
Ok I'm a complete idiot when it comes to Linux. I'm a hardcore Windows XP user and I'm trying Mandrake 9.2 download edition for the first time.
I installed Mandrak 9.2 Download distro on a Toshiba Portege 3015CT laptop just to give it a test run. The installation went well until I started configuring the wireless. I have an SMC2632W PCMCIA card and the OS detects the card fine. When I set the wireless access without the WEP encryption it works fine. Although this may be fine, I don't want my neighbors to accidently access my WAP. When I do configure the wireless access to point to use the WEP. It doesn't work at all. Can anyone help me out? PS. I'm starting to loose faith on Linux if I don't get the wireless working properly. Thanks. |

Maybe if you explained what you have already tried it would help......
In general, you can set your WEP key at any time with the iwconfig command: iwconfig wlan0 key PutYourWEPKeyHere Of course you would replace wlan0 with whatever device name your wireless card actually has. |
first of all go into control center and make sure that the ssid is set to "linksys" or whatever u hav goin on there. just to be sure that worked go into terminal and su and type "iwconfig" and see if it piks up the correct information. if not then thye iwconfig wlan0 essid (name of essid without parenthesis here) where wlan0 is the name of your wireless card
if still not able to get it to work go in terminal and su type killall dhcpcd when thats done type "dhcpcd -d wlan0" (where wlan 0 is the name of your networking card) hope this helps and happy linuxing! |
Ok thanks for responding! I will try this iwconfig. I will let you guys know how it turns out.
Oh by the way, what format does the WEP key look like: do I have to put it HEX or just like it is and is it case sensative? I'm trying to configure the card to use 128 Bit WEP. I have the 26 alphanumeric characters. |

I'm getting the following error now when I try to use " iwconfig eth0 enc"
Error for wireless request "Set Encode" (8B2A) SET failed on device eth0; Operation not supported. LOL! I tried everything and it's still says Operation not supported. ?? I must be doing something wrong. Any ideas? On ifconfig i have lo eth0 eth0:9 <- I don't know what adapter this is.. |
Please post the output of both iwconfg and ifconfig. I'm curious as to what device has actually been assigned to your wireless card. Since most computers these days have a built-in ethernet card and those are frequently assigned eth0, I want to make sure that we are looking at the right device.

If you're concerned about other people getting on your network (like your neighbors) and WEP encryption is giving you a problem, do what my buddy here has to say...

MAC addresses are easy to spoof, especially in Linux. The MAC of each client and that of the AP are sent in the open each time a probe request occurs. MAC address filtering is an extremely weak layer of security, especially if you believe that it's protecting you and take no other precautions.
A reasonable analogy is using a combination lock to secure a door, writing the combination on a Post-it and sticking it next to the lock. Victor, The command should be: iwconfig ethx key 1233456778 ... To make it stick, use the Mandrake network GUI or edit the script file (probably something like /etc/sysconfig/network-scripts/ifcfg-eth0) to include your WEP key. The syntax for the file in Red Hat was 12:34:56:78 ... Should be the same in MDK 9.2. |
