could this be an issue of network card???

hi all,

i use fedora 5 which dual boots with XP and the sys configuration is below:
mobo : asus kbs series
processor : AMD Athlon 2800+ n 80G HDD with 512 RAM...
there has been a strange prob right from installation of Fedora with this internet , we have a LAN here and after all lan and other network settings being intact , i can ping to all other comps on my network..

now the real problem is i can't connect to internet say neither i can surf in any browser,no messenger works , and even tried yum in vain after configuring it to use with a proxy coz it worked with many of my frenz comps... who use asus and amd ...

even internet settings work perfectly on my XP ...

i strongly feel that there are no probs regarding network settings as i myself have configured successfully the same on many of my frenz comps.. and even my firewall is disabled..

plzz donn feel bored and i go here providing as many details as i can:

a sample output of nmap with one of the servers is below n works intact..
[root@localhost ~]# nmap -p3128

Starting Nmap 4.00 ( ) at 2007-01-29 19:55 EST
Interesting ports on
(The 1663 ports scanned but not shown below are in state: closed)
3128/tcp open  squid-http

Nmap finished: 1 IP address (1 host up) scanned in 13.959 seconds
kernel version:
[root@localhost ~]# uname -r
as it might be required the output of /sbin/lspci
[root@localhost ~]# /sbin/lspci

and somthing regarding "wget"
 this output is same as on my frenz comp.. so that shudn't be a prob..
[root@localhost ~]# wget http://djha:djha@
--20:07:29--  http://djha:*password*@
           => `'
Connecting to connected.

I'm guessing you don't have your gateway properly configured. What is the output of:

$ netstat -rn

Also, check that your DNS server is properly configured in /etc/resolve.conf. If you can't ping this:

$ ping -c3

but can ping this:

$ ping -c3

Your DNS is not properly configured.
