"Limited or No Connectivity" Linksys Wireless router.

I have a Linksys router and an AT&T PCMCIA card. I've had this equipment
working FINE for nearly 3 years (maybe more) using WEP encryption.

That is until last night. Last night it started telling me that it had
"Limited or No Connectivity" whenever I try to connect to my network. The
card works fine because it connects to my neighbor's network and I have to
disconnect it so that I can try and connect to MY network. It tells me this
in WinXP Home (SP2) connection mgr.

The router is providing IP addresses because a different PC on the network
(connected to the router via Cat5 ethernet) gets an IP address from the
router and is able to access the internet.

I figured there was something wrong with the WEP encryption. So I disabled
WEP on both the router and the PC card. Guess what--my network is no longer
listed as an available Wireless Connection (in Windows XP's connection
manager).

I enabled WPA-TKIP on both the router and PC card. Now I'm back to "Limited
or No Connectivity". I've confirmed that the pass key I'm using is correct.

I passed frustrated a long time ago.

Can anyone offer any suggestions?

Thanks!
 
Thanks for the reply. My responses to each item are below.


<<However, if your computer is not configured as a PPPoE client computer and
the computer obtains an APIPA address, that is a situation where limited
connectivity exists. Therefore, Windows XP should indicate that the local
connection has limited connectivity. For example, this might occur if a
Dynamic Host Configuration Protocol (DHCP) server is not available on your
network.>>
The router's DHCP is working--it provides an IP address to a PC connected
via Ethernet. (this is actually the PC I'm using to post this).

You may also receive this message when one or more of the following
conditions are true:

<<Your DHCP server is down on a hardwired network. On a home network,
this server could be your Internet service provider's server your personal
router, or your DHCP provider.>>
Same as above.
<<Your DHCP server is down on a wireless network. On a home network,
this server could be your ISP's server, your personal router, or your DHCP
provider.>>
The same router that uses DHCP to provide the IP address for this PC
is the WIRELESS router that I'm having trouble getting my laptop to connect
to.

<<On a wireless network, this message may appear when you use an
incorrect Wired Equivalent Privacy (WEP) key or if you do not have a WEP
key.>>
I've checked the key FOUR TIMES. I even DISABLED WEP on both the
router and the laptop.

<<You may not have an IP address, or your TCP/IP settings may be
corrupted.>>
Don't know how to fix/or test this.
