Ping Timeout on Cisco 827

[Bizounett]

Hi,

I Have a Cisco 827 that is running fine for about 10 minutes. After this time I begin to have a ping timeout.

I change my cable, change port in my switch and connected directly on my laptop, same issue.

Thanks in advance.

Here is my running config :

I ping the local IP address, in this case 192.168.2.1.

The time is around 1 week.

Thanks

I made the same test with a Cisco 2610 with ATM card. Same issue, after 15 minutes, the ping to the local interface of the 2610 have a lot of time out. Anyone have an Idea ? I saww the they handle more than 800 translation NAT at the time. Maby this the part of the problem ?

Thanks in advance

Rene

What else is this router connected to?
I'm wondering about your topology - do the test again with the router connected to nothing except your laptop on the console port only.

Thanks for the reply,

This installation is at Home. I share my internet with one of my neighbor. He said to me that he done a lot of emule and torrent. We working like that since 3 years without any problem. Until last week I was working with a Pix 506E. But he begin to lost internet connection and must be reset each 2 days, but the ping to the local interface of the Pix was perfect all the time.

I thought that my Pix was broken. Then I decide to install a router and this is all my history.

With the Router 2610 (Even 827), when my ping to the local interface have a lot of timeout, from console I can ping on the internet. Then I don't lost internet connection. When it's in trouble, I ping from the Router an internal IP address, lost 50% of ping.

Topology : Modem DSL -- Router 2610 -- Switch Cisco 2924XL

No one have an idea ?

Make a list of all the IP addresses you are using on the devices to see if you have a conflict.

Check all the router interfaces for errors ("show interface")
