Trouble to connect with Linksys Wireless-G USB adaptor

I have a D-link AirPLus 802.11g router with a Linksys
Wireless-G 802.11g USB adaptor on my notebook for internet
access. My ISP is Earthlink Cable with Times Warner. The
adaptor worked fine all along. But recently it couldn't get
an IP from the DHCP server somehow. I checked its TCP/IP
setting. They're all fine. It's set to automatically
getting IP from the DHCP server. Can some of you experts
help me to troubleshoot?

The status on the router shows

Command IPCONFIG on the said notebook shows nothing for
fields like

DNS Suffix Search list
Connectionn-specific DNS suffix
DHCP Server
DNS Server

Its IP address is a self generated IP, different from
192.168.0.xxx.

I did ipconfig /renew. It would say it can't get an IP from
the DHCP server.

The IPCONFIG on my other working wireless desktop, which has
a D-link AirPlus Wireless 802.11g USB adaptor, shows:

C:>ipconfig /all

How about the model numbers instead of the marketting names?

OK, you have WEP 128 enabled. My guess(tm) is that somehow, the WEP
key either changed or was scrambled. First, dive into the router
settings and disable WEP encryption. You should get an IP address and
connectivity should be restored. Then, re-install the WEP128 keys in
both the router and the client configurations. However, you're about
to have a problem. Dlink and Linksys use different ASCII to Hex
conversion algorithms. If you use an ASCII key on both ends, it will
not work. Try using ASCII but I'm fairly sure you'll need to use a
Hex key for this to work.

You're right. The key somehow was erased. But it didn't
complain about that when making the connection. And the
connection can actually be made but no ip was assigned.
After I retype the key, the internet was back to life.

So simple for such a big headache.

Congrats.

I was going to say something nasty about MS WZC (Wireless Zero Config)
but I couldn't tell for sure if you were using WZC or the connection
tool that came with your Linksys USB radio. Microsoft did a rather
nice job of dealing with ASCII vs Hex and 64 bit vs 128 vs no
encryption. Just type in the key and it will guess its way through
the combinations and permutations. That part works fairly well.
However, they forgot to include any kind of diagnostics or error
messages. Not even a log file buried where mortals can never find it.
The only clue that you have a WEP key mismatch failure is that WZC
shows "connected" followed by "Obtaining IP address". It sits at
"Obtaining IP address" for about 2 minutes until it times out, where
it delivers an IP address of 169.254.xxx.xxx and announces that you
have "limited connectivity". For all the work MS did on XP SP2, one
would think that error recovery and logging would have been
implimented and tested. Nope.
