Hello,

Starting from January, my Internet connection has become "unstable". I mean that I get occasional interruptions of the connection. This is particularly annoying while listening to a webradio or using voip. Of course, prior to January 2010, I could stay hours or days without interruptions.
Now, I have to reconnect manually every 5 min to the service although the reconnection to the ISP is done immediately.

So, before I take my axe and visit the office of my ISP, I would like identify where is that connection drop happening. Is it at my pc? at the ADSL modem/router? or the ISP?

I use a wireless connection with WPA to my router. Then, the router is basically an ADSL modem. I am running Kubuntu locally.

How can I follow up on the network status between different elements and see who is cutting off my connection?

Thank you for your time!

Use a program like mtr to trace the route to google.com, in the event of a failure you'll see each hop that succeeds and fails, the connection issue occurs between the last success and first failure.
