wg311T wireless adapter not working centos

[prabakar007]

Hi everyone,
i am newbie to Centos5 ...I am having both ethernet and wireless card(wg311T)..

And installed the driver for wg311T(madwifi-0.9.4.tar).

I finished the configuration settings as follows

1. Run the "make" in the directory madwifi
2. Then do a "make install".
3. vi the /etc/modprobe.conf file. Add a line alias ath0 ath_pci
4. vi /etc/sysconfig/network-scripts/ifcfg-ath0
Add this:
STARTMODE=hotplug
DEVICE=ath0
BOOTPROTO=dhcp
WIRELESS=yes
MODE=Managed
ESSID=<Your network name goes here>
IPV6INIT=no
onBOOT=yes
USERCTL=no
PEERDNS=no
KEY= <Your security key goes here if you have one>

5. ifconfig ath0 up
6. ifup ath0
7. vi /etc/resolv.conf
Add this:
name server 192.168.1.1

The problem i faced is
DHCP server is not assigning the IP automatically.
Even i tried manually Wireless is not working properly..

Pl anyone help me.

Dunno if this'll help or not, but this seemed to work for me in Kubuntu 7.10 (saved this as a .sh and ran it to connect):

#/bin/bash
# Main commands
# iwconfig

# To create an access point, use:
wlanconfig ath0 create wlandev wifi0 wlanmode ap

# Connecting using WEP key:
iwpriv ath0 authmode 1
iwconfig ath0 key <hex key>

# To get an IP address:
sudo dhclient ath0
