Smile No DHCP offers received (wifi ) Wireless detected unable to connect

I have (i think) NDISwrapper working , but when i run the command dhclient wlan0
the output i have got is displayed below
(command iwconfig-a displays)
linux-qzyt:/home/fedexpress # iwconfig -a
-a No such device
Does it means i have to get the drivers first for OPENSuse11

linux-qzyt:/home/fedexpress # dhclient wlan0

I'd say the card is not being detected or the driver isn't loaded.

What is the output of ifconfig?

Also, if you want much help you'll have to list wireless NIC type.

You might want to use the search function -------->

But, from memory, I think you have to bring the wlan0 up: "ifconfig wlan0 up". To bring it up and give it an address is "ifconfig wlan0 up" I think. You should be able to see wlan0 included in the response to "ifconfig" (no "-a"). You should probably be able to see a list of routers with "iwlist wlan0 scan".

Try those commands, but do a search on "ndiswrapper suse" and see if you can get some more targeted threads that will help. I know that there are already lots of threads here about ndiswrapper.

Try "iwconfig wlan0" or just iwconfig, there is no "-a" option, at least according to the man page for iwconfig on my system. When I want to manually configure a wireless connection for a managed network with a dhcp server, I use these steps: (as root or with sudo, and my wireless interface is eth1, substitute wlan0 or whatever is appropriate)

ifconfig eth1 down
iwconfig eth1 mode managed essid "YourNameHere"
ifconfig eth1 up
dhclient eth1

I have found that the ifconfig statements are not necessary on my system, using an Intel Pro Wirelss 2200BG card with the ipw2200 driver, but from what I've read, may be required by some other wireless drivers.
