Q:
Random Request timed out when ping router?
Network performance, Ping, Network connectivity
I just noticed my internet was unstable and slow.

I connected my laptop directly with leased line modem, I can able to work & ping without request timeout

But when I connected through router am facing this problem, Random Request timed out when ping with router

I am suspecting the problem with router configuration

So I restarted the router again the same problem…

C:\>ping 123.182.139.178

Pinging 123.182.139.178 with 32 bytes of data:

Request timed out.
Reply from 123.182.139.178: bytes=32 time=130ms TTL=243

Firstly, don't think that PING is 100% reliable, it is a very useful tool, but the packets can be failing for a number of reasons, and can be filtered or dropped because a device is too busy, or a number of other reasons.

However, if the test works fine from your laptop, but not through the router, then the router config is a very likely candidate as the cause of the problem.

Have you tried the PING test from the router itself ? Did this also drop the packets ?

If that works, then it is the router config that is probably at fault, if that also fails, then it may be a routing issue, or a problem between the router and the modem. If that is Ethernet, have you fixed the speed and duplex ? Try setting it to auto, reset the link, and try again.

If none of the above helps, then can you post a copy of the config here ? It is difficult to diagnose when we cannot see the config ! (or even know what model of router it is).


Tks for u r valuable responds

Router : Dax DX-1821

I tried the PING test from the router itself, I got replay with out request timed out.

Which connection is your Internet ?

You appear to have two, one on fastethernet0 and one on fastethernet1, with default routes to both (ip route 0.0.0.0 0.0.0.0 123.182.4.225 and ip route 0.0.0.0 0.0.0.0 123.182.138.176) so what is happening is that one packet goes out of fastethernet0 and one goes out of fastethernet1 and so on.

If you only have one true Internet connection, remove the second route. If you have both and the second one is a backup, then change the route by adding a higher metric, for example

ip route 0.0.0.0 0.0.0.0 123.182.138.176 10

It would help to decide the correct answer if you can confirm and explain why it looks like you have two Internet connections.

Post the answer in the discussion please.
