Router assings TCP/IP but cannot ping router

[NM]

I have one desktop and one laptop in which I used to connect using crossover
cable. Both computer has Windows2000 professional. It works fine. I connect
to internet from the deslktop using dialup connection and the connection is
shared via internet connection sharing. So I can browse from my laptop using
the shared dialup connection.

I wanted to get rid of the cable and use wireless router. The wireless
router in question is D-Link DI-514 which has 4 LAN port and 1 WAN port.
Here is the situation.

I have tried the following combination. Connected the LAN port of the PC
with the LAN port (notice not WAN) of my wireless router (as i stated above,
it has 4 LAN port
and 1 WAN port) using ethernet cable. Then I connected the LAN port of my
Laptop using ethernet cable to the LAN port of the wireless router. The WAN
port of the wireless router is set a fixed IP address 192.168.1.1 with
subnet mask 255.255.255.0. The WAN port is not connected to anything (since
I want to share my network between my pc and laptop primarily and may be
share dialup
connection of the pc). Both the LAN card of the PC and the Laptop is set to
get IP address automatically. The IP address of the wireless router is
192.168.0.1 and it is setup to act as a DHCP server. Everything works fine
upto this point. The PC is assigned the IP address 192.168.0.101 and the
Laptop
is assigned the IP address 192.168.0.102. Both PC and Laptop can ping each
other, can ping the wireless router and use windows filesharing.
Now I removed the LAN card from the slot of Laptop and connected the
Wireless Lan card (The card works fine in my office so no problem with the
card). The wireless router is
setup with the same SSID as it is setup in the Wireless Lan card. WEP
security is disabled. Wireless Lan card is setup to get IP address
automatically. The Wireless Lan card gets IP address from the Wireless
router. The assinged IP is 192.168.0.100. The wireless Lan card shows
excellent radio connection. But I cannot ping the wireless router
(192.168.0.1) or the PC (192.168.0.101). The PC can ping the Wireless router
but cannot ping the Laptop.

Can someone please help?

Thanks

Dumb question, Are you still using the crossover cable? If so, there's your
problem. How about with the desktop? Can you ping the router from there?

Trying assinging a static IP address to the wireless card. Then test
ping them. Problem maybe arising from the router addressing scheme.
Usually the .100 addy is reserved to the router as a starting point
with .101 being the first DHCP addy (at least in my experience with
consumer routers).

I'd like to try that, but need a few more details. At present, ipconfig/all
shows the wireless adapter has 192.168.0.102 assigned to it while the
desktop (cabled to the router) has 192.168.0.100. The router is
192.168.0.1. Are these correct assignments? And, I have the TCP/IP
properties on the wireless set to "Obtain an IP address automatically".

With that setup when I ping from the wireless laptop I get the following:
192.168.0.100 Unsuccessful
192.168.0.102 Successful
192.168.0.1 Unsuccessful

Incidentally, this Toshiba laptop has a utility called ConfigFree that
diagnoses the "possible problems between the laptop and the router" as
being:
a) "There is no response from the DNS server"
b) "There is no response from the default gateway"

To do what you suggest, when you say "assign a static address to the
wireless card", how do I do that? This is a Toshiba laptop running XP Home
with a pre-installed built-in wireless card.

Thanks.

Under the network properties/neighborhood icon on the desktop you
should be able to find your wireless card. Select it's properties and
on one of the tabs it should say something about automatically
obtaining an IP address. Change that and assign it one, as well as
match the gateway up to the router usually 255.255.255.0 i.e.

I know its not a very detailed explanation and I apologize for that
but I am feeling the crunch of year end. hope this helps!!

We had a similiar problem and it took us many hours of headache trying
to nail down the actual problem. My son had a new Toshiba Tablet
Portege 3505 with an integrated wireless card which didn't work with
my D-Link DI-514 router. Toshiba tech didn't give a helpful solution
and we have tried all sorts of things until I saw a post "DI-514 and
Airport" through Google.

It says: Go Advanced/Peformance in DI-514 interface and change the
"Preamble Type" from the short preamble (default) into long preamble.

This provided me a very hint. I tried and it worked!!!

I have another laptop Thinkpad T-22 with Win 2k using a D-link
wireless card which never had any problem with the short preamble
setting, which made me believe the router wouldn't have been a touble
maker. I was wrong!!!

DI-514 router is on sale now for about 30 dollars and I imagine more
and more people will encounter a similiar problem if they are using a
non-D-link or integrated wireless card with XP OS.

I suggest you give a try and good luck to everybody who suffered from
this bogus...
