Guest emptysquare Posted December 30, 2004 Report Share Posted December 30, 2004 Below you'll find a long listing of a bash session. The short version is this: I have my wireless card almost working, but my "iwconfig" commands have no effect. I can't change the essid, WEP key, or mode. Perhaps as a result, dhclient doesn't get any leases. Mandrake 10.1 official on a Toshiba Portégé 7020CT, D-Link DWL-650 card.

Steve Scrimpshire Posted December 31, 2004 Report Share Posted December 31, 2004 iwconfig wlan0 key "restricted XXXX-XXXX-XX" Try that. Also try: iwconfig wlan0 ap 00:06:25:24:D7:D3 although you may not have to after adding the quotes around "restricted XXXX-XXXX-XX" Don't know why it doesn't give you an error for the key command, though.

Havin_it Posted December 31, 2004 Report Share Posted December 31, 2004 Have you tried putting the necessary configs in a file instead? For this interface it would reside at /etc/sysconfig/network-scripts/ifcfg-wlan0 (if it's not there you can create it) Contents should be something like this: DEVICE=wlan0 BOOTPROTO=dhcp HWADDR=<your wifi card's MAC address> ONBOOT=<yes/no, up to you> WIRELESS_ESSID=WGENLAN WIRELESS_MODE=Managed WIRELESS_ENC_KEY=XXXXXXXXXXXXXXXXX <I don't use quotes for mine> MII_NOT_SUPPORTED=yes WIRELESS_HOSTNAME=jdavislaptop.wgenhq.net NEEDHOSTNAME=yes There might be something missing, but I'm not on my Linux right now. Will check later... Quote Link to comment Share on other sites More sharing options...
Steve Scrimpshire Posted January 1, 2005 Report Share Posted January 1, 2005 Have you tried putting the necessary configs in a file instead? For this interface it would reside at /etc/sysconfig/network-scripts/ifcfg-wlan0 (if it's not there you can create it) Contents should be something like this: <<snip>> WIRELESS_ENC_KEY=XXXXXXXXXXXXXXXXX <I don't use quotes for mine> <<snip>> <{POST_SNAPBACK}> You also don't have an encryption key with a space in it like this: restricted XXXX-XXXX-XX Quote Link to comment Share on other sites More sharing options...
Havin_it Posted January 2, 2005 Report Share Posted January 2, 2005 I never put any hyphens in my key and it works okay. I don't know if this affects things for different hardware(?) Quote Link to comment Share on other sites More sharing options...
Guest emptysquare Posted January 3, 2005 Report Share Posted January 3, 2005 Hey, guys. Thanks for all your replies, I've tried them all: putting the info my config file, entering the WEP key with no spaces or hyphens. Still, I can't change my wlan0 configuration. Is this maybe a driver problem? --maybe the driver's misconfigured, so iwconfig can't successfully change parameters? I'm using ndiswrapper with the drivers off the CD that came with the DWL-650.

Steve Scrimpshire Posted January 4, 2005 Report Share Posted January 4, 2005 If you run the command iwconfig wlan0 key "restricted xxxxxxxxxx" That should give you some results. If not, try it without the 'restricted' part, try it with 'open' instead and also try it with just the key. Quote Link to comment Share on other sites More sharing options...
Guest emptysquare Posted January 4, 2005 Report Share Posted January 4, 2005 Whoopee!! It works now. My sysadmin told me to do iwconfig wlan0 key s:XXXXXXXXXXXXX and now it works. What I hadn't known before is that setting parameters with iwconfig actually tries to connect to the network immediately. So, if I put in the wrong key, it has no effect because the driver tries & fails to connect with that key right now. Doing iwconfig wlan0 gives me the state of the network. So now I understand its behavior. Thanks for your help, guys! I'm now happily downloading & configuring Samba. Quote Link to comment Share on other sites More sharing options...
