2 computer and a wireless router

Hi,
I have a lan with this configuration:
1) a desktop computer directly connecterd to internet with an adsl modem
(usb + atm) (ip: 192.168.0.1, win2000)
2) a wireless router (asus wl500) to which the desktop is connected via
ethernet (ip: 192.168.0.2)
3) a laptop connecter to the wireless router (ip: 192.168.0.3, winxp)

I can ping from one computer to the other (and to the router) and can share
folders between the two computers. But problems arise when I need to use
other services. In fact I cannot surf in Internet with the laptop, nor fetch
mail nor connect with MSN messenger. I tried to install a proxy server on
the desktop computer, and using that I can connect to MSN messenger and surf
(even though the connection to internet is very slow and some pages do not
work at all - for example I cannot make searches with Google). Also, this is
not a very comfortable solution, since I am forced to reconfigure every
program so that it uses a proxy server.
Can anyone help me please?
Thanks

I would change the configuration slightly, modem to router then to
computers. This will give you easier network access to each computer,
they have a common point of contact, and a router has a built in
firewall. Not a very good firewall but a firewall none the less.
When this is wired, turn EVERYTHING OFF, modem, router, all computers.
Then one by one turn everything back on in this SPECIFIC order, modem
wait about a minute AFTER all lights are on, router, wait another
minute, computers ONE AT A TIME. Change each computer to obtain and IP
address and DNS automatically BEFORE turning them off. Changing them
later would require a reboot anyway.
This shoud provide both computers internet access without the need for
any proxy stuff.

As for local inta-net you need to be sure BOTH computers are in the
SAME workgroup, my computer, right click for properties, computer
name, change(for XP). The upper/lower case is not important just that
the name be exactly the same on BOTH computers.
You need to then go to each computer and double click my computer and
do a right click on the C drive, then click sharing and go thru the
process. YES you want to share the files and printers on each machine.
Then you should be able to see each machine on your local lan.
As for getting into each one from the other one you need to check and
see if it works like it is, if not come back and I will lay out those
steps too.

Without the proxy but the rest of your configuration the same can your
desktop surf the net(since your laptop can not). If yes, from a browser
on your laptop put in the ipaddress of yahoo (216.109.112.135). Does the
site come up. If yes there is a issue with your DSN settings on the
laptop if no, try to run a trace route to a website with your pc(like
yahoo, they do not block pings and traces). Then do the same trace route
with the laptop. See where the fail point is. I'm assuming that your
static on your ips and not dhcp. If your are running dhcp then look at
you dhcp server(again I would bet DNS). Hope this gets you going down
the right road.

Why don't you have the wireless router directly connected to the adsl modem?
That's the way all your docs show it, and everthing works fine that way.. I
don't understand why people do it their own way, and then wonder why it
doesn't work?
For pictures and text see
http://usa.asus.com/products/communi...g-internet.htm
very first thing it says:
Share broadband Internet around the home
Connect to external ADSL / cable modem via one 10/100Base-T auto-crossover
(MDI/MDI-X) Ethernet port
Four port switch with 10/100Base-T auto-crossover (MDI/MDI-X) Ethernet port
connect to local PC
IP sharing (NAT)
UPnP-enabled NAT traversal to enable MSN massager, Netmeeting, Direct Play,
Xbox live!
PPPoE client to connect remote ISP PPPoE server
DHCP server / client and DNS Proxy

see the first thing listed... "Connect to external ADSL / cable modem via
one 10/100Base-T auto-crossover (MDI/MDI-X) Ethernet port"

Because he has a USB Modem and his router does not have a USB connection..
