Linksys Wireless Router WRT54G Problem

I have a problem with the above and my one PC with a WUSB54G adaptor.
It used to work, but has stopped working recently for no apparent
reason.

I have upgraded the router firmware to IIRC v3.03, and can SEE the
network, which says that the connection is good, but IE6 refuses to
access websites. Access is possible via my Ethernet Card connected to
my cable set-top box.

I use ZA Pro, and have made sure that I have added the DHCP and DNS
server addresses to the trusted zone (and also tried the internet zone)
to no avail. I have tried switching off ZA Pro to no avail.

I can access the router set-up via the wireless adaptor, have tried
cloning the MAC address, tried switching off WPA security, both to no
avail.

Does the fact that I cannot access any websites even by connecting the
Ethernet cable to the router and the router to the set-top box imply
that the problem is with the router ?

Any help would be much appreciated as I'm completely lost now and am
not especially au fait with wireless routing anyway, so am generally
just trying things I find in this group.

TIA

Did the problem occur before or after you upgraded your router's firmware?

Before.
One of the first things Linksys and the various forums said was to
ensure that the firmware was up to date.

It seems like a DNS problem.

try to ping a domain (ping wanadoo.fr). You should receive 4 reply's.

If you receive the IP of wanadoo.fr, your DNS is working.

i tried to ping yahoo.com but received no reply at all.

So, what does this mean ?

That you've got a connectivity problem. Any other details on what's
hooked up where, and what other troubleshooting you've done?

Sorry, I missed the rest of this thread. When you connect the cable
modem to the router, do LEDs on each of them come on to indicate that
the connection between them is OK? The one on the WRT54g is labelled
"Internet", while the one on your cable box is probably "Ethernet" or
"PC" or "Data" or something like that.

Try powering everything down, and powering them up in sequence (cable
modem, then router, then PC) waiting a minute between units for
everything to come up and the lights to stop flashing.

Also, try "Ping 216.109.112.135", and give us the results of
"ipconfig/all" in a DOS box.

Two LEDs come up, the power LED and the Internet LED. I tried powering
everything down and up to no avail.

As indicated previously, configuring the router via wireless access is
possible, so the connection there is fine. It's just internet access
beyond that that fails (except via an ethernet cable).

I'll try the cmd stuff this evening when I get home.

Thanks for the reply, though.

And what lights up on your cable(?) modem?

So you can talk to the router, but it doesn't seem to talk to your
cable modem. That's either because of hardware problems (you
indicated that this used to work just fine, yes?), MAC address
problems (most cable systems only talk to one true MAC adress, though
most of them will look for a new one if you power cycle the cable
modem), or some other connectivity problems (cabling, etc).

What does the router's status page show for the Internet? IP address,
subnet mask, default gateway, DNS, MTU?

I connect via a cable set-top box. The model doesn't have any extra
lights indicating BB internet access unfortunately.

The following is what I get from ipconfig/all
