A couple of things to check:

Firstly, check that your modem is compatible with Fedora Core 7

Second gather the output from the following command from windows:
Code:
ipconfig /all
Compare this with the output from the following commands from Linux:
Code:
ifconfig eth0
netstat -r

From a web browser (Firefox) try browsing to the following address:

http://212.58.227.74/

This should take you to the bbc.co.uk homepage

If this works then your problems are down to DNS.

Add the DNS Servers

203.145.184.13
202.56.250.5

When i open that ip address from firefox or konquer the title of the browser immediately changes to
“BBC-bbc.co.uk home page....” but after a while, say after 3 minutes the page gets completely loaded in konquer... but in firefox it says “looking up www.bbc.co.uk” and remains half loaded in the progress bar..now after 6 minutes the bbc page is loaded in firefox as well... if i run the same ipadress in windows it takes only 4 seconds or less for the page to load.. and no other wesites r opening except this ipadress...its so confusing... pls help me out.. whats going on??

OK you need to add a reference to the DNS servers

203.145.184.13
202.56.250.5

If you have a graphical tool to configure your network connection, there should be a DNS section to add these ip addresses.

Alternatively modify the /etc/resolv.conf file to look like:
Code:
nameserver 203.145.184.13
nameserver 202.56.250.5
You will need to be root (or sudo) to edit this file.

Sorry for the delay in getting back, I was celebrating England getting into the Rugby World Cup final.

Last thing to check before I start running out of ideas.
Look at the /etc/nsswitch.conf file, should be something like:

Code:
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         compat
group:          compat
shadow:         compat

hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis
I wouldn't change the router configuration as this seems to be correctly configured.

Has this ever worked on this PC?
If not then reinstalling would probably only bring you back to this point.
If it was working, what has changed recently?

We are getting to the point where you are going to need to use a network analyzer e.g. ethereal

When you moved to FC7, did you do a clean install or an upgrade?

It might be best (once you have backed up your data) to perform a clean install and go from there.
