Thread: Why Default Gateway fails frequently in BSNL PPPoE ?

This happens to me frequently and to others in my area.

What is reason behind this ?

Is this a issue with the customer's modem or with the BSNL ?

seems OK. Test in Tools. similar modem.
On "Always On" PPP/PPPoE mode. "Pass" In Diagnostics page also.

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 2ms, Maximum = 3ms, Average = 2ms

probably the problem is with ur computer since i faced the same problem and the reason was my computer

Please see the Device Information page of your router.

I think this test is happening on BSNL's side of the router, not the home LAN side. Thus, 192.168.1.1 has nothing to do with this.

The device info, or status, as appropriate to your model, should show you the router's default gateway on the WAN side. It is the ping to that which is failing.

Whilst you can try pinging it from your PC, if the router can't reach it, it is unlikely that you will.

This is a BSNL problem. One for the Helpdesk.

I feel, The "PING" test is same as OS cmd application.
we access the cmd from modem.
I entered 192.168.1.1 ) modem to computer)


Device info bsnl gateway

google dns 8.8.8.8

If not functioning in Modem Tools, problem may be on OS side.
"Fail" in Diagnostics may also indicate problem in connection.

You can verify. Unplug the telephone connection. That ping, along with a few other things, will now fail.

Having tried that (it did fail as I predicted), I noticed the magic words above that section of the test screen:

Test the connection to your Internet Service Provider

Aha! Voila! I should have seen before.

The first section is called Test the connection to your local network

By the way: your router need have no idea what your PC's default gateway is.

Removed cable rj11 to modem. ( no connection to BSNL)
Ping 192.168.1.1 OK as reported earlier. ( from Tools menu)
tests the connection from modem to laptop.

Obviously Ping DNS or Gateway won't work.
("Other things in "Diagnostics" result depend on Internet connection.( not the point under discussion )

You can verify. Unplug the telephone connection. That ping, along with a few other things, will now fail.

Please follow my reasoning, my example, and, most important, my quote from the screen (Test the connection to your Internet Service Provider) carefuly. You picking up on two words, "default gateway," and thinking they refer to one thing. They don't: they refer to another.

Try it without DHCP (I don't use it). How, then, would your router know what your PC's "default gateway" was? It wouldn't, and it is not relevant to your router to know that anyway. It could be some other router.

More evidence that it is not one guy's LAN problem.

will wait for feedback from @Sledgehammer.

Checked the stats today. The Default Gateway is working fine.

I'm not having any problem with pinging the modem. (Also I'm not using DHCP.)

Done a traceroute to google.com. No packet losses. Everything is fine.

But the Default Gateway usually Fails even when the Internet is working fine. Don't know the reason behind it.

That I can't explain!

clarification: does it always fail, or only sometimes?

It's not failing frequently.

OK.

Been away for ten days. How are things now?

Now the problem is not there. Not sure that when it will come back.

Keep fingers crossed. Could be BSNL fixed something their end.

Hopefuly, problem is resolved.
