Internet Connection Testing

Copy of a post I made on the support group about internet connection issues and pictures

"I want everyone to see these photos. These are screen shots of my modem's configuration page, along with speed test results from my PC.

Notice, the column that says "Uncorrectables"? This is a sign that theres noise in my line, coming from somewhere.. could be my actual physical connection from my cable wire to my modem, could be the pole outside.. could be a neighbors faulty splitters causing a spike in the system and is shooting back noise to the pole. Rebooting my modem will sometimes correct a faulty noisy signal. This is also why sometimes Dino Provenzano will say "tell your provider to send a new signal" because it will purge your line and start fresh.

Now look at my speed test, notice that despite the noise, I am showing over 100mbps? Do you also notice what is called "bufferbloat" during my test? This is latency. Latency is the true cause of buffering (when the problem is on your end and not the link's end). Your speed in mbps is simply your data capacity. You can ship a lot of cargo on a huge tanker ship, but it will take a long time to get back and forth between destinations. Opposed to say a bunch of 747 cargo planes going back and forth from Hawaii to LA. You can get away with less mbps if your latency is always amazing. If your latency is up and down, you need high bandwidth to compensate for when the latency fluctuates (and it will!).

On a speedtest.net app, such as on our box, it only shows the ping while idle, not while under load. My ping for my test while idle was 8ms but look at how high the ping got while under full load... 2616ms!! This causes buffering. So when people come around and say "I know it isn't my connection! Stop saying it is my connection!!!!"

Unless the server of the link itself is experiencing latency and heavy load..

IT. IS. YOUR. CONNECTION.

Thank you."
