I use a lan connection to connect to the internet. I wanted to share
that connection between a desktop and laptop so i bought a LINKSYS
WRT54GS. I plugged that LAN cable into that Internet Port of the ROUTER
and did all the configuration but still can't access the internet. Can
anyone please help me? It doesn't even works on the host computer...

Is the WAN (Internet) side of the Linksys being configured properly?
What IP address is it getting? Subnet mask? DNS servers? Gateway?
What connects your LAN to the Internet?

Do you mean the PC which is directly connected to the router? How can i
tell it is being configured properly? I am not allowed to get
administrator knowledge about the network so i don't know what connects
my LAN to the internet.

Can i solve this problem by using my wireless router as a wireless
access point?

Then how did you get permission to do this? Many (most?) network admins
would consider this a rogue access point and a serious security risk.

That issue aside, you can tell how the router is being configured by
what gets displayed in the configuration interface.

Run IPCONFIG /ALL on a connected computer to get the other info I asked
for, copying and pasting the exact output here.

My guess from what's probably going on is that you probably want to
configure the WRT54GS as an access point, not as a router, as described
in the HowTo wiki below. At the very least, this should give you the
same kind of access you have now with your computer when wired. Whether
or not you can add another wireless computer would depend on what kind
of LAN security is in place.

Another option is to add a wireless client adapter to the (presumably
wired) desktop computer (instead of the WRT54GS) ; create an Ad Hoc
wireless network between the desktop and the laptop; and share the
desktop Internet connection with the wireless laptop using Internet
Connection Sharing on the desktop.

p.s. Please don't switch posting styles (top vs bottom) in mid-thread
-- it's confusing, and considered a bit rude. Thanks.

This output shows that your computer is behind a NAT router, so you
definitely want to configure your WRT54GS as an access point, not a
router. That's covered in

Is this a company / corporate / academic LAN? If so, you should ask
your administrator for assistance - in many jurisdictions attaching
your own unauthorised wireless devices to LANs you don't own is a
/criminal/ offense and can certainly get you fired / suspended.

However: forget about the Internet port on your router, you don't neee
it. Connect your PC and your existing LAN to the LAN ports on the
router, turn off any DHCP server in the router, and give both it and
the laptop fixed ip addresses in the 192.168.1.x range (but not ones
used by any other computer on your lan - if you use one from another
computer, you will break their connection and /definitely/ get in big
trouble).

Even this may not work. Many company LANS assign IP addresses only to
registered authorised hardware.

I connected PC and my existing LAN to the LAN ports on the router. But
now i cannot access my router's configuration. The Problem is that the
default LAN IP of the router and the DEFAULT GATEWAY of my existing LAN
connection are the same by default. How can i now access my router's
configuration?
