What *EXACT* version of the DD-WRT firmware. See my previous message
for how to find the exact version.

I'll describe:

I would prefer if you would itemize, but I guess describe will work.

Location A:
Internet Backbone.
Linksys BEFW11S4 V4

Yech. I have one of those router. It hang at irregular intervals.

Location B:
Linksys 54GS in client mode connect to BEFW11S4
PC1 - local lan
PC2 - local lan
Laptop. Wireless direct to BEFW11S4

OK, other than the lack of detail, I now understand your setup.

I lost the connectivity of the 54GS as client to the BEFW11S4.

Any encryption? BEFW11S4 v4 only supports WEP. Be sure to use the
Hex key, not the ASCII key.

While at the same time, I could connect wireless with the laptop to the
BEFW11S4

Not a good assumption. I have a neighborhood LAN with about 5
wireless connections. It's not unusual for one of these connections
to go dead, while the others remain working. I have no idea what is
the cause of that problem but I do know that it's related to the
BEFW11S4 router, as my other routers (WRT54G v1.1, Motorola MR840?,
DLink DI-614+) do not have this problem.

So I did some testing.
Setup the 54GS as AP.
Plugged PC1 into the WAN port (to simulate internet backbone).
PC2 plugged into LAN port.
Laptop connects wireless to 54GS.
This worked fine - showed me that all electronics in the GS54 worked.

Yep. An excellent test of everything except the DHCP client in the
WRT54GS. However, as the other clients computers were apparently able
to access the internet through the WRT54GS, this is not much of a
test.

A better test would be if your WRT54GS in client mode can "see" other
wireless networks using the built in site survey. See:
Status -> Wireless -> Site Survey button

Reset configuration:
PC1+PC2 connected toi lan on 54GS.
54GS setup in client mode, name of central AP network setup again.

How did you setup the "name" (SSID???)? Did you use the site survey
tool? There's nothing to type if that's the case. Just click on the
SSID and be sure you save the settings.

The 54GS got the wireless connection, and a fine signal.
But the 54GS never got a DHCP connection to the central AP.

That's the same thing I get with my BEFW11S4. Actually, even if you
had a valid IP address, it just sometimes decides to drop one or more
wireless connections. Interestingly, it also does the same thing on
wired connections.

Just kept on logging : udhcpc[1264]: Sending discover...

So finally I rebooted the central AP, and now it works.

Yep. I use the same fix with an AC lamp timer to reboot the BEFW11S4
every night.

What weirds me, is that at all times, the laptop could connect to the
central AP and get an IP address via DHCP.

So I think there is an elusive bug in the DD-WRT somewhere.

Nope. It's in the BEFW11S4. Try it with a different wireless router
and see for yourself.
