I have a desktop machine with a Netgear WG311 card in it. I have a
Linksys Wireless Access Point WRT54G that it has always connected to
without problem. All of a sudden I'm getting some weird behavior.
The machine can no longer see the network although it claims it is
connected via the WAP. It is using the Netgear utlity to connect, and
always has. But suddenly I can no longer get a DHCP address. I tried
to give it a static address, but it still could not see the network,
nor could anybody see it. Again, the odd thing is the Netgear utility
claims it is connected to the WAP. The WAP does not report the
connection in its log files. It worked on Friday when I went home.
It didn't work on Monday when I came in. Windows 2000.

Any ideas?

Make sure you are not connecting to your neighbor's wireless. Check the
SSID.

Thank you. Yes, I checked that. The only network it sees is the one
in house and the SSID matches. I have WEP on it, which it asked for
and accepted. But yet when you look at the router log, the connection
is not there.

It may be as simple as a NIC gone bad, but it intrigues me.

What makes you think that the WEP password was "accepted"? Try
temporarily reconfiguring the router to disable all security and try to
connect. You may have to delete a stored profile for that SSID if the
configuration utility you're using to manage your wireless adapter
stores the password.

The solution may be as easy as restarting your router. Have you done that?

Yes, several times. As for why I thought it accepted the password, it
immediatly came back and said connected. But it never said it
acquired and address. However, you make a good point, I'll try
disabling the security and see what happens.
