hi
1st of all i m APPSDBA,i have a network configuration problem @ my work station .
i have a one m/c in that i install XP and Linux AS4 means dual boot.there we r using wireless local area network(using Netgear).

issue : using XP i can communicate with other machines and i can access the internet also. while i boot into Linux i cant communicate !
so i tried to configure the network like
i gave host name @ ]# vi /etc/hosts
and ]# vi /etc/sysconfig/network-scripts/eth0 (for local WLAN)
and said ]# service network restart (every thing "ok" here)
after this i gave ]# ifconfig
it just showing 127.0.0.1 and some stuff(that i dont know wat those 4 or 5 lines).
really i shock while i saw it. network saying okey but its not showing IP.

for XP its fine then wat happen to my Linux(i m not etting wats the prob).

my system configuration is:
==>cpu 2.2 core 2 DUO
==>CABINET ATX WITH SMPS
==>MBD GIGA BYTE 31
==>LAN CARD Wireless Netgear.

i m not sure wat i m giving the info about netgear but i m giving the thing wat was on bill(while purchase it).
Netgear - 'WG311-V3'
54mbps - wirelss
pci adpater, 32bit pci

And i m giving some system information [According to that plz suggest me wat to do for this Prob]
