Hi guys, i've some problems with my wireless connection.

All is recognized and when i run "iwconfig" it shows me the "wlan0" with its parameters and with the Access Point address, but when i try to run the command "dhcpclient wlan0" to get the Dynamic IP the system answers me that cannot recognize that command . I've also tried to run "ifup wlan0" but it tells me that the IP address is not yet available. help me please !

THIS IS THE SHELL OUTPUT AFTER THE IFSTATUS COMMAND :

(none):/home/agaz1985 # ifstatus wlan0

wlan0 configuration: wlan-bus-usb
dhcpcd running

I had the same problem with my Toshiba laptop not being able to connect to my router. It turned out that it didn't like my WEP key. I turned it off and just had MAC auth on and it worked fine. You could try that.

hope that helps.

I would suggest turning off WEP encryption and trying w/ just MAC address filter only like he suggested. Also, dont bother with WEP. Its unsecure anyway. All you need is Aircrack or some variant and you got someone's WEP key.

Once you get your connection going, setup WPA. Much safer.

I'm on wireless w/ WPA right now on my laptop. I used Linuxant which saved me the wireless hastle but I had to manually setup the WPA deal.

Anyway start small, then add after.

Thank's guys ! All it's ok ... now. It was a WEP problem, I put in a wrong WEP code and so the acess point denied me the access.
