The other part of the discussion here seem to point to modems as a culprit. I have a modem/router Belkin . I hope someone can shed some more light on this as I fail to understand how modems will make much difference in throughput as they are just a bit of hardware and my speeds would probably not stress the modem's limits. Also at $120-140 to just see if it will improve my throughput I really would like to know a bit more about this.
From what I understand, some cable modems are faster than others. It really depends on the technology supported by your ISP. For example, if your ISP supports Docsis 3.0, then you'll get better performance from a Docsis 3.0 modem than you would from a Docsis 1.1 or Docsis 2.0 modem. Docsis 3.0 uses channel bonding, which "enables multiple downstream and upstream channels to be used together at the same time by a single subscriber".
https://en.wikipedia.org/wiki/DOCSISIn my case, the Docsis 2.0 modem I had wasn't working properly, either because of a hardware issue with the modem or the ISP made some technology upgrades that crippled it. The new modem I have is Docsis 2.0 as well, so that, in itself, can't explain the speed problems I had with the other modem. My problem was clearly a modem issue but judging from what you've said, your modem might be OK.
There are a lot of other factors that can affect the speed of a cable modem. The quality and length of the lines are major issue. Make sure you have as few splitters as possible in your home wiring. Those things can cause major signal problems. If you're in a rural area, chances are that you might have infrastructure problems or you're a long distance from the signal repeater.
Some cable modems allow you to look at the signals coming and going If you have one of those modems, open your web browser, enter the IP of the cable modem and take a look and the signals you're getting. It might give you a clue as to why you're not getting higher speeds.

If your cable modem doesn't allow you to view the levels, you will need to have your ISP send a tech out to check them.
Good luck with your effort to get more speed!!
