Need help to diagnose and fix my wireless LAN setup.

Given:
- Router which is also a wireless AP.
- Laptop with ethernet interface and pcmcia wireless card.

Problem:
Wireline works fine, but wanted to turn on wireless.
I believe it all used to work, but
I have not used in a while and now having a problem.

Router shows that the wireless client is connected.
The wireless config utility on laptop says connected.
But dhcp does not get assigned.
after a little while "Autoconfiguration IP Address" gets assigned.
If I assign a static IP and restart the interface -
trying to ping the gateway - I get timeouts.

Not sure what to try next.

Are you using WEP?

1.  Try it without WEP.

2.  Try assigning a new SSID to the AP.  This will force the computer
to create a new profile as well.

3.  Try doing a factory reset on the AP.  Sounds like maybe some sort
of authentication is enable.  Sometimes it will register a connection,
but won't pass traffic or assign an IP because it is not
authenticated.

Let me know if none of that fixes it for you.

Thanks!
