Can access the internet through the browser, but cannot ping.

[Don J]

I'm using Windows XP.

I've got two computers talking to the internet through a router. Up to
today they have worked just fine. Today I purchased a Belkin Wireless
router. I havn't used the wireless option yet but am having problems.
Behavior is identical on both machines!

1) My original router: Can access the internet just fine from both
machines. Same for email. Doing a:
"ping 192.168.2.1"
Times out 4 times with no messages returned.

2) The new router when operated in "non-wireless" mode: The internet cannot
be accessed from either machine. Same for email. Doing a:
"ping 192.168.2.1"
Is always successfull. Four messages are successfully rececived.

The data seems to be somewhat inconsistent. Either pinging works and
internet access doesn't, or vice versa.

I called support at Belkin. At the time of the call we couldn't get the
wireless device to work in either "Internet Explorer" or "pinging" mode. He
told me that someone would call me back and hung up.

What's going on? I am especially concerned with the "pinging"
inconsistencies. What do they mean?

"Network Setup": Two machines are connected together by a pair of ethernet
connections through a router. A third connection on the router connects to
a Comcast broadband connection to the internet.

Don't understand your question about "Protocol", unless "TCP/IP" answers it.

1) "Client for Microsoft Networks".
2) "File and Printer Sharing for Microsoft Networks".
3) "QoS Packet Scheduler".
4) "Internet Protocol (TCP/IP)".

I am using the Norton Symantec firewall.

AND NOW a question for you: Am I right in thinking that 'pinging' is a
precondition for access to the internet? Hence, since I can access the
internet through the browser, when using my usual router, but can not ping,
something is drastically wrong.

Hi Don,

No offense meant . . . but did you remember to reset your
ComCast modem?

I use ClearWire, and anytime I change the router, switch or
hub that it is plugged into, I have to reset it.

One way to start diagnosing the problem is to try and load
the routers control page. On my Belkin, it is 192.168.2.1 if
you can do this, then that means your computer is talking to
your router.

The next step as I said earlier is to make sure that your
router is talking to your modem. I would unplug all
communication devices. Then set up just the modem. Once the
lights show a modem ready signal I would then plug in the
router and see what I get. Also, if you have been tinkering
with the router, I would do a 'factory' reset of the router.
before connecting it to the modem.

Ciao . . . C.Joseph

Yes, I pulled the power on it and then re-powered it.

How do you do a factory reset of the router? I simply pulled the power plug
on it.

Hi Don,

Don's Question: How do you load the Router control page?

You didn't say what model router you are using. on My Belkin
router. All I do is bring up a browser and in the URL bar type;

192.168.2.1

I am then greeted with a page that shows the status of the
router. If I wish to make any changes, I click on login and
type the password and make whatever changes I need to. Note
that some changes require that the router reboot itself.

Don's Question: How do you do a factory reset of the router?
I simply pulled the power plug on it.

Most of today's router have Flash memory so simply pulling
the power does not delete settings on the back of my router
right below the DC power jack is a little button that I push
and hold for 10 seconds and it resets the router to factory
defaults.

BTW, you placed you signature above your response as a
result, your response was read as a part of your signature
rather than a response. You need to keep this in mind since
some news readers can be set not to show signatures which
means that for those people, they would not have seen your
response.

Check your firewall > Configure button > Network tab/link (depends on version).
Add any machines by IP, IP Range or Subnet that are not listed in the Trusted zone.

If no joy check all the below:

Right click My Network Places on the Desktop.
Click Properties.
Right click Local Area Connection.
Click Properties.

Under "This connection uses....."
Click "Client for MS Networks".
Click Properties.
Select "Windows Locator" from the dropdown box, if disabled skip.
Click Ok.

Scroll to and select Internet Protocol (TCP/IP).
Click Properties.

Under the General tab make sure "Obtain an IP address automatically" is selected.
Click the Advanced button.

Under the DNS tab:
Selected "Append Primary and Parent DNS suffixes.
Register this connections address in DNS"

Under the WINS tab > NetBIOS:
Selected Default.
Ok out of MNP.
Reboot if required.

Test connectivity:
Open a command prompt, click Start > Run, type in: cmd and press Enter.
At the prompt type each command below and press Enter after each.
**Note: Command noted by =, Space noted by ^. Do not type the = or ^.

=ping ^ 192.168.1.1 *Routers IP, change as necessary.
If it times out then there is no communication between the router and machine.
If not then the machine communicates with the router.

=ping ^ google.com
If it times out then there is no connection to the net.
If not then net connection is established and all is well.

ping 127.0.0.1
If it fails it may be a TCP/IP stack problem.

Ping each computer from the other using the UNC:
=ping ^ computername
If it fails either way there's an IP or Name resolution problem.

If pinging times out on any address, to see if the machines IP is correct along with
other settings.
= ipconfig ^ /all
If anything isn't correct, at the prompt type and press Enter after each command:

=ipconfig ^ /release
=ipconfig ^ /flushdns
=ipconfig ^ /renew
=ipconfig ^ /registerdns
=exit
If that fails reopen the command prompt, run release and flushdns only and exit.

Shut down the machine.
Pull the power from the router.
Pull the power from the modem.
Wait approx 30 secs.
Apply power to the modem and wait for it to finish synchronizing with the cable.
Apply power to the router and wait for it to finish synchronizing with the modem.
Power up the machine.
The machine should now be assigned a new IP from the router.
Run ipconfig or attempt net connection to test.

There is no "firewall>configure" Button!

There is no "firewall>configure" Button!

Did you purchase/install only Symantec's Firewall, it wasn't included with another
Sym app that you instaslled it with?
Did you try everything in my previous response? If yes, what were the results?

Also suggested by myself and C.J.D was that you check the settings in the routers
web based configuration, from what I read you haven't done so yet. It also appears
you haven't checked the routers documentation for the info on exactly how to get into
the web based configuration as was suggested by myself. If you don't know how to get
at the routers configuration that tells me the Default username/password is still
set, by not changing the default un/pw to something else puts the router and your
networked machines at risk of being compromised.
