OK, I did the speedtest, my results were 1480 kb/s download and 2369 kb/s upload.
Do I compare this to my speed 54mbps to understand? I guess I don't know what a "good" number is, like I don't want to be paying Comcast $$$ and be getting the same speed I could be getting from dialup for $ or DSL for $$.
Thanks for enlightening me!
The number you're seeing (the 54Mbps) is the speed at which your wireless connection to your router is running. Really, you'll never even get that speed back to your router for lots of different reasons that you probably wouldn't care about.
Your cable provider will also give you a speed, usually like 5Mbps or 3Mbps, which you'll probably never reach either. Running the speed tests at http://speedtest.net
will usually give you a good estimate of your speed, but there are so many factors involved, you can't take what speed they give you as a concrete number. You're always going to have a slower upload speed on cable services, too, mostly because of the way it all works. I think you may have reversed your numbers in the speed test, or there was really some sort of issue with the connection to the test server when you ran the test.
They usually give you the speed in Kbps, too, so you have to convert that to Mbps if you want to compare, with 1Mbps = 1024Kbps.
You're always going to get better speeds on cable or DSL than on dial-up, which is called 56Kbps but it technically can't go that high, and you'll really only get 44Kbps if you're lucky most of the time. DSL you would have to check into to see if it's available to you since it doesn't go the distance of cable.
