how to gauge the reliability of Internet or wifi

is there a tool that can be run for a day to see how many packets are lost or some measure to see how reliable the internet connection is or has been.i am thinking this in relation to just not speed but overall reliability and if it goes down for few seconds or milliseconds between DSL and cable and wifi.

I use DU Meter for this. It is inexpensive and monitors your overall bandwidth. If there is a dropout, you will see it. I have been using this tool for a number of years. dumeter.com .

You can also use the Resource Monitor in Windows. Turn it on and look at the Network tab. You will have to check in occasionally.

thanks John. I see it is not free. do you find any other benefits from it other than checking the reliability of the network.

regards, it should be a good tool to have.
JohnBusiness Consultant (Owner)Commented:
Most tools (including the one I referenced above) will show dropouts and throughputs. You have to gauge reliability by testing different sites at the same time. Apple software downloads are dead slow for example, and are no measure. No tool will tell you reliability. You need to test sites side by side. Common dropouts on all sites indicate poor reliability.

thanks. worth considering ..yes

would you say with 'Resource Monitor in Windows' you have to monitor manually and with DU, you can just check history and not have to be manually present all the time..

Resource Monitor needs to be look at from time to time. DU Meter keeps a history and can report on it after the fact. Both are useful tools and I use both.

thanks John. what exactly are you looking for in the graphs of Resource Monitor? there should not be any drops or gaps?

The network graph has spikes and graphs.
TCP is flat and even kind of.

Can you please post a screenshot of what you would consider health network condition please?

Here is a picture of my Network Monitor. Remember nothing measures reliability. You must compare two sites at the same time to see if the issue is local or web.
