Jan,

I presume that "...you can still connect to the internet..." is when you're
connected modem to computer, and things are otherwise working?

Disabling Zone Alarm is frequently NOT a good solution. I say this so many
times - see some of my past posts. You may have to un install it, totally.

If you do un install ZA, please keep your connect time, modem to computer, to an
absolute minimum. And enable the built in XP firewall, immediately, after you
un install!!

OK, this is getting a bit frustrating. Let's summarise (correct me if I'm
wrong). And forgive me if I ask you to repeat yourself.

When you're connected modem to computer:

The computer can ping, and can do anything on the internet, as required. Even
without your running the ISP software (and entering account / password), after
rebooting the computer?

How about you post "ipconfig /all" here, taken when the computer is successfully
connected to the modem and able to access the internet?

When you're connected modem to router to computer:

The router is connecting to your ISP - at least the status page for the router
reports an assigned IP address. Does this ip address look reasonable - is it
similar to what the computer gets when connected modem to computer?

The router is connecting to your computer - you are able to view the router
status page, and make configuration changes. You have just one computer, right?
You've tried a different cable connecting the computer to the router, right?

The computer cannot ping by ip address to the internet.
Results from a basic ping test to 66.94.230.33 (www.yahoo.com) by ip address:
Ping statistics for 66.94.230.33
Packets: sent = 4, Received = 0, Lost = 4 (100% loss)

Try another ping target say 66.102.7.99 (www.google.com),

I don't see any obvious problem with the computer, nor with the ISP service, nor
with computer to router connectivity.

What version of the DI-704P do you have?
http://www.dlink.com/products/support.asp?pid=63&sec=0#manual

I'm thinking something in the router configuration. I'd start by looking at the
manual myself, but since the manual varies for the three models (listed on the
page), that probably won't be productive.

I keep thinking PPPoE. Configure the router for PPPoE, plug in the account /
password that you use when you run the ISP software installed on the computer.
Test by pinging 66.94.230.33 AND 66.102.7.99.

See if the router supports MAC address spoofing. Do "ipconfig /all" from a
command window on the computer, and get the computer MAC address from that.
Plug that into the router.

See if the router supports MAC address filtering. If MAC address filtering is
enabled, maybe the computer is being filtered.

See if the router supports time based filtering. Maybe a time filter instructs
the router to disallow any traffic.

See if anyone at the BBR / DSLR DLink forum has any ideas. I did a brief search
for current articles on the DI-704P there, nothing with your experience shows
up. http://www.dslreports.com/forum/dlink

Try the BBR UKBB forum http://www.dslreports.com/forum/ukbb.

Do a hard reset of the router.

Finally, contact DLink product support. Tell them methodically what you've told
me, maybe you can put the above summarisation to good use.

You could try BT support too. Dunno what their policy is for routers though -
some ISPs make you unplug a router before they'll help you.

Don't stop watching this thread though.

Cheers,
Chuck
