I'll assume you have a WRT54G and are running Windoze XP.
In the future, kindly disclose what you're using for hardware and
operating system so that I don't have to wake the genie in my crystal
ball to devine your setup.

Look in the file:
c:\winnt\system32\drivers\etc\host
with an editor (i.e. Notepad) and see if you don't have a large
collection of lines that look like:
127.0.0.1 www.symantec.com
127.0.0.1 www.norton.com
127.0.0.1 www.mcafee.com
127.0.0.1 www.antivirus.com
etc...
These will redirect these web sites to your own machine. DNS lookups
will fail. Delete all these except the line:
127.0.0.1 localhost
which needs to stay. Search for:
"browser hijack"
with Google for details.

You'll need to run run a virus scan and a spyware scan to make sure
you don't have any uninvited software running.

So much for my crystal ball. I'll work on getting its guesswork
calibrated.

That is weird. In theory, the firewall, on or off, should not have
any affect on DNS lookups unless the DNS cache in the router is
affected. However, that should be cleared with just a power cycle.
You might wanna start over and reset the WGA54G to defaults with the
reset button (hold until the front panel lights flash), or the web
interface, in case some other settings have been hosed. I don't think
the setup wizard does a grand reset.

Yes. Just a guess(tm). The router has a DNS cacheing server. The
router does the DNS lookup and then delivers it to the client
computah. The client computah has it's DNS server settings set to the
IP address of the router. If the DNS cache in the router gets somehow
"stuck" with only the current IP's in the cache, it will only deliver
lookups for what it know (and is in the cache). If connectivity to
the internet fails, the router will still deliver DNS lookups for
what's in the cache, but nothing new can be added.
