Basically these results are pretty good. As you can see, things are better on the downlink than on the uplink, and the biggest difference is reflected in the packet discards and maximum delay time. The difference in quality is not unusual since you have more bandwidth on the downlink than on the uplink.
As far as improving things is concerned, you first need to be sure that nothing (except the modem) in your local setup is contributing. Do this by eliminating any routers, Vonage adapters, etc. and, with your computer plugged directly into your modem, repeat the test. If you get similar results, as you probably will, then you're bumping against the limits of your internet service, and there's not much that you can do without the cooperation of your ISP. |

Unless you can isolate your problems to your local network, you're basically going to have to ask your ISP to fix your connection. It may or may not be possible for them to do it, and they may or may not be willing. But it's worth a shot. It may involve some rewiring, or a replacement of your modem, or they may be able to make modem adjustments or backbone adjustments to fix any problems they find.
But, first, connect a single computer directly to your Internet connection and re-run the test. If your numbers improve significantly, then you need some upgrades to your local network equipment, or you need QoS http://vonage.nmhoy.net/qos.html if other services or computers on your local network are competing with Vonage. |
