I don't know what's wrong here, I can't seem to ping any website, not even google or this website - it just keeps saying 'timed out' with all packets lost. The only thing which I seem to be able to ping is localhost, which pings successfully. Why is this?
Here are the the results..
>ping google.com
Pinging google.com [173.194.36.6] with 32 bytes of data:
Request timed out.

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:

Can anybody please tell me why is this happening? :mellow:
Thanks in advance.

Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:
  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Users, Partitions and Memory size.
  • List Minidump Files
Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using "Reset FF Proxy Settings" option Firefox should be closed.

Your router appears to be blocking ICMP type 8 and 11.

Please reset your hosts file: http://support.microsoft.com/kb/972034 and see if the issue is resolved.

Nope, resetting the hosts doesn't fix it. I knew you'd tell me to, so I already tried that soon after I posted - no change, I still I get the same result on pinging.

EDIT: I booted into Windows XP and tried pinging, but it yields the same result on pinging so HOSTS or anything with the OS might definitely not be the issue.

Is this affecting website connectivity?

Well your router or your ISP is preventing ICMP Traffic of any kind. Call your ISP for guidance.

I guess Google's firewall block your ping command. This is very common method for the website host to use. You can compare with other major wrbsites, like yahoo, mocrosoft...etc.

A ping to Google and Yahoo is always a standard part of this test (run it yourself to test the ToolBox) -

There seems to be a block via the routers output, and this is what beeds checking -

Oh, so that's the reason. Thanks then. :)

I've never heard of google blocking ping requests but I have heard about microsoft doing it - but my problem existed with any and all websites, including this one. So like cryptodan & noknojon stated, it must be the ISP. Thanks for your help anyway. :thumbup2:

Thanks guys. I'll talk to my ISP and see what he says. Anyway this shouldn't be an issue, if he does or not, since it does not affect my internet connectivity, I was just being a little curious to know. Right guys? :wink:
