Ping request timing out.

When I try to ping my DSL modem, I get the following msg:

C:\WINDOWS\DESKTOP>ping 10.0.0.1

Pinging 10.0.0.1 with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 10.0.0.1:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum =  0ms, Average =  0ms

My speeds are pretty good (I have a max of 1500/384 and ususally get around 1200/325) and I don't appear to have any other problems.  However, a tech at Earthlink told me that this may be a symptom of a modem problem.  He tried transferring me to tier 2 support but after holding for 45 min plus I had to go.  I am using a Speedstream 5260 with Earthlink/Covad DSL on a P3/933 w/ 384 mb ram and Windows ME.  When I ping 10.0.0.2 everything appears fine.
Any ideas?

This may sound silly, but I dont know what IPs are on your network. Are you sure the Modem is set to 10.0.0.1? whats the internal IP of the winME box?

Use 'NETSTAT -R' to show the "routing" of IP-packets.
Post the output here.

Unless your computer is assigned as '10.0.0.1',
or there is a computer on your local area network assigned as '10.0.0.1',
PING _will_ "time-out".

As far as I knew it you NEVER had an internal ip just to use your DSL modem. Your DSL modem will most likely have an internal (private) IP address but your pc won't. Unless your not directly connected to the DSL modem itself ie. through a firewall/router. Expanding on what Otta said.

If you don't know the IP of your cable modem or your pc you can do one of these to find it.

1. goto Start Menu --> Run, type winipcfg <hit enter>
after selecting your NIC you should see your ip address. If your not connected through a router or firewall, this address SHOULD be a normal IP not one of the INTERNAL address that are reserved for home/office networks these are known as private or reserved addresses.

10.0.0.0       to     10.255.255.255
172.16.0.0     to     172.31.255.255
192.168.0.0    to     192.168.255.255

Any address within these ranges are reserved addresses.

Ok, so hopefully you found your IP address. Now to find your DSL modem's address. You should have a handy tool called Trace Route installed on your machine (I can't remember if Win ME has it. I know my 98 machine does) and type this

tracert -d www.sc.rr.com        (use YOUR DSL providers website)

you should get an output like this (except the IP's)

C:\>tracert -d www.sc.rr.com

Tracing route to www.sc.rr.com [24.31.195.201]
over a maximum of 30 hops:

  1   <10 ms   <10 ms   <10 ms  10.210.96.1
  2   <10 ms   <10 ms   <10 ms  24.31.193.89
.....
.....

You want to look at the 1st line which is

1 <10 ms  <10 ms  <10ms  10.210.96.1 <---- this will be the IP of your DSL modem

Now you know what your IP and your DSL modems IP is. Now do what otta said and check your routing table.

> Your DSL modem will most likely have an internal (private) IP address but your PC won't.

It's the other-way-around -- your PC has an IP-address,
and it is connected to the communications-device (cable-modem, DSL-modem, or analogue modem) which just "communicates" your IP-packets.

Any IP-packets "addressed" to your IP-address
are never "terminated" within the communications-device;
the IP-packets are "forwarded" to your computer.
(Put another way, the comm-device is not "addressable",
except by "out-of-band" signalling.)

Sorry if I was un-clear,

Your DSL modem will have a private/reserved IP address. ie within the range
10.0.0.0       to     10.255.255.255
172.16.0.0     to     172.31.255.255
192.168.0.0    to     192.168.255.255

Your PC will have a normal Internet IP address. ie, not in the above range.

> Your DSL modem will have a private/reserved IP address.

No, it is a "MOdulator/DEModulator" device.
As such, it has *NO* IP-address.

> Your PC will have a normal Internet IP address.

No.  It's the other way around.
The network-card inside the PC "owns" the IP-address;
the modem is just a communications-device.

In my case, I have a D-Link DI-704 Cable/DSL Router
between my high-speed modem and my computers.

The DI-704 has the "normal" IP-address,
and each PC on my home LAN has a '10.xx.yy.zz' IP-address.

I don't want to get into a flaming war here but

How come you can telnet to you dsl/cable modem if they don't have IP addresses.

What specific DSL/cable modem has this capability?

When I try this (from my office computer),
it is the TELNET-daemon on my home-computer
which sends the "please login" prompt,
i.e., the modem "communicates" between my home-computer
and my office-computer  --- no more, no less.

Your Mileage May Vary.  :-)

OK, sorry folks, I've been a little busy.  Thanks for all the input.  For what its worth, when I ping 10.1.1.1 everything is fine.  I am wondering if the tech I was talking to gave me the wrong numbers to try to ping.  The whole reason I was speaking to the tech that day was because my connection kept dropping.  Since then I have found the cause of that (a new Dazzle PCI device I had installed) and fixed it.  My connection no longer drops and has been very reliable.

Gareth-  Where do I get trace route?  I can't find it.  What is the filename to look for?

the program file is called tracert.exe

I'm not sure if windows 9x/ME has this tool but I have it on my Windows 98SE machine

try looking in either

c:\windows or
c:\windows\command

else I stuck it here for you to download its only  4.2kb

Disregard my last message, I got it going and when I pinged that 1st IP address it worked fine...0% loss.  What is NETSTAT-R and where do I find that?

NETSTAT is the command-name, and '-R' is the option to display "routing" information.

Try:  NETSTAT -R > NETSTAT.OUT
and then:  NOTEPAD NETSTAT.OUT
and then:  ERASE   NETSTAT.OUT

to see "all" of the output.

> What does it all mean?

You "lost" the column-headings, which doesn't help you interpret the output.

The "routing" table tells your computer what computers
are "local" (on the same subnet) and how to route IP-packets
to specific networks.

You've got a lot of "special" routes -- it must be the AOL software which adds them, but I don't know why.

Yikes!  That is one _busy_ routing-table.

Does the 'PING' work _while_ connected to AOL?

Disconnect from AOL, and repeat the 'NETSTAT -R' command.
You should see many fewer routes.
Post what you see.

Does the 'PING' work when _not_ connected to AOL?

Yes the ping works with and without AOL when I ping 10.1.1.1 (the 10.0.0.1 still doesn't work, but I really think that was a mistake on the techs part).

For those who do not believe a cable modem can have an IP address are also unaware of what DOCSIS compliance is.  There are websites you can go to and YES, Cable modems have IP addresses.

Interpreting:

All IP-packets addressed to '10.1.1.xxx' are to be sent
through '10.1.1.1', which is '2' "hops" away.

All IP-packets addressed to '10.1.1.1' are to be sent
through '127.0.0.1', which is the _first_ hop,
i.e., the "local-loopback adapter".

Note that 'PING' does _NOT_ use the TCP/IP protocol;
it uses the ICMP protocol.
I've seen "messed-up" Windows 95/98 computers that
had no trouble using TCP/IP (i.e., TELNET, web-surfing,
Real Audio, online gaming),
but the 'PING' and 'TraceRoute' commands would always "time-out",
or give some other error-message.
(The best solution for this type of malfunction
is "reinstall Windows" -- sometimes, deleting all the
TCP/IP adapters & clients & protocols, and then
reinstalling TCP/IP is sufficient.)
