How can i keep my internet connection stable?

My internet connection says 100mbps, and I've usually only ever been able to download at a rate of 90kb/s. Every now and then though, it hikes up to a max of 950kb/s but then goes back down in a few days. What can i do to make sure it stays high?How can i keep my internet connection stable?
The quick answer is there is no way to keep it stable you are at the mercy of the ISP.How can i keep my internet connection stable?
There's actually a number of things going on here:





1.) 100mbps indicates your LAN connection, but not your overall internet connection. Your computer is connected to your router or modem at 100mbps, but your router/modem is likely connected to the internet at a much lower speed. So, anything that has to go out of your own network (basically, the internet) is bottlenecked by the slowest connection. An optimal 100mbps can achieve approximately 11.5MB/sec.





2.) Referring to the bottleneck situation above, the bottleneck may not necessarily be your internet connection. If the server you're downloading from is slow, then you're going to get a slow speed.





3.) Depending on the quality of your ISP, your connection quality may not necessarily be consistent. This is especially the case with Cable providers, where everyone in your neighborhood shares the same line.





There's a reason why the internet is called the ';information superhighway,'; and that's because the internet functions pretty much like a set of highways. Your 100mbps connection from your computer to your router is like a driveway with a 11500 KB/sec speed limit. Then, your cable connection is basically like a narrow highway with approximately 2000 KB/sec speed limit (depending on your provider), but because it's shared, it almost always is in a state of a traffic jam; how bad depends on the time. Then, the server has its own driveway, and just like an inadequately designed parking lot, those may jam too.





General idea is - most likely, it's out of your control. Call your ISP and yell at them.
100mbps refers to your computer's connection to the modem or router. That is the speed of your local network basically. To accurately determine the speed of your internet connection, go to http://www.speedtest.net
