When I ping google.com, I get a terrible results. I have more than 30% of lost packets. WHen I ping my gateway, I receive only 2-3% of lost packets. My question is, how can I know what is the problem? How do I know if the network is ok, but I am having bad signal with my notebook, or it is some segment of network that is the cause of the problem?

THanks,
Goran

well ... try using cable connection and see if you still got losses over pinging. if not, we can troubleshoot from there on

Actually, its a ADSL line, and as I said, the line is working well. Meaning, when connected directly to it, internet works well, no packets lost.

Let me rephrase my quesion. Lets say that I have a  WLAN network that consists of several segments, all the connection is done by wireless. I receive a lot of packet drops. My question would be:

without going to each of the APs to connect directly to them to troubleshoot the problem, is it possible to use some software/commands that will show me which part of the network is causing the problem? How to check the packet "state" during its way to google.com? How would I be sure that its a LAN or ISP problem? I repeat, I am interested in method that will allow me to troubleshoot from one place.

well ... since using wired you got no packets loss, then it's not your ISP's problem. it has to be at your end. and since you are using only WL then, it's gonna be a bit difficult to find the AP where you got a problem. even if you tried troubleshooting remotely you wouldn't conclude anywhere since you still wouldn't know where the error comes from. try pinging another website, not google, that is local at your country

Pinging DNS servers gives the same results. Still cannot believe there isnt any method than can tell me from which point the packets are taking longer to arive (or dropping).
