I have the following scenario.

D-Link DI-624 Router. with 4 port switch.

Laptop 1:. D-Link DWL-G650 Wireless Card.
Laptop 2: Intel Pro/Wireless 2915ABG built inl Wireless Card
Laptop 3: Hard wired to LAN. I am using this as a file/web server.

All systems running WinXP Pro SP 2 with all latest updates.

When I disable all security on the router and all wireless Laptops the whole
network works fine. Full Internet access and LAN access all round.

However when I set up security on the router as

WPA-PSK problems start to arise.

Laptop 1 works fine and has no problems if security is set to WPA-PSK, TKIP.
It has full Internet and LAN access to Laptop 3. And Laptop 3 can access all
shares on Laptop 1

However Laptop 2 gets into trouble when set up with WPA-PSK, TKIP.

It has full Internet access via the router no problems.. However it has
problems seeing the Windows Network and tells me it is not available.
However it can access Laptop 3 via UNC names.. And Laptop 3 cannot access
drive shares on Laptop 2.

I have disabled all firewalls and tried everything under the sun imaginable
to the setting of Laptop 3 the fix this issue but no go so I am at the end
of my rope. I have tried to use the Intel Pro client, the Windows client to
make changes all to no avail. There are other minor quirk that go on too
numerous to mention. These mainly deal with not being able to ping other
machines from Laptop 3 when security is implemented.

I really would like to get this sorted because the idea of running the
wireless network without any security does not appeal to me. I don't know
whether this is a Intel Pro issues, a WinXP issue or something else.

Suggestions greatly appreciated
