You're going to LOVE this!
I live for entertainment value.
OK, so I go to FREEping, fire it up and it pings everything (see
previous message) with 100% success.
OK, so you have connectivity to the internet. It's not the wireless,
the DSL modem, or the ISP.
OK, so I go back to FREEping and think of a site name that I
haven't visited in years (per your suggestion). I enter the name
and FREEping pings it perfectly with 100% good pings.
Argh. That means that DNS is working and you can lookup new domain
names. So much for the DNS cache theory. Time for a new theory.
I go to the browser and enter the name and I can't reach it.
Browser's stone dead. ALL the browsers are stone dead in terms of
being able to look up sites. So are three mail clients and
newsreaders.
So much for the theory that if you can ping it you can browse it.
Well, it's not DNS. Next time this happens, instead of FreePing which
is a bit tedious, try just pinging *NEW* sites with:
Start -> Run -> cmd <enter>
ping www.example.com
ping www.another-example.com
If they return pings, then DNS is working. If they return errors,
then DNS is not working. From your previous description, it will
probably work. So much for the DNS theory.
How's this for weird?
Yep. Makes little sense. Previously cached connections that should
have worked, such as the mail servers, no longer work. Yet, new
connections work just fine for only ping but not for other services.
Old connections continue to work. It's not DNS.
I've seen something like this before and it was defective router
firmware. Ping would work, but nothing else. It was not exactly the
same as it required the router to be rebooted, not the client
computer, to return to normal.
Some questions:
1. Do you have any other computers on you LAN available for testing?
At this point, I'm still not 100% sure it's not your computer.
2. Can you cure the problem by rebooting the router instead of the
computer?
3. Are you using an anonymous browsing service, web accellerator, or
anonymous browsing? If you're NOT using a proxy server, make sure
that there are no proxy like settings left over from something.
In Firefox 1.5, it's:
Tools -> Options -> General ->
Connection Settings -> "Direct internet"
Also, in IE6, it's:
Tools -> Internet Options -> Connections -> LAN Settings ->
Uncheck everything
If you ARE using a proxy service, web accellerator, or anonymous
browsing service, then trashing these settings will break them.
Scribble down the setting so you can put them back.
4. Is the Zyxel P-330W firmware the latest?
5. Do you have access to a spare router? Sustitution might be a good
way to isolate the culprit.
