My seven year old Dell Precision Laptop has been chugging along at a just okay 150 mbps internet download speed for about a year, even though we pay for double that speed. Had the cox tech come by last year and he blamed it on the computers age, so I shrugged and said I could live with it. The last several months it really started slowing down--less than 100mbps. I thought something was wrong with our incoming Cox cable lines, so had the tech come to the house again. His equipment measured over 500mbps incoming at the modem/router. My laptop is hard wired because the wifi card stopped functioning, so we thought the cat 6 cable might be bad. Sure enough, when I unplugged the laptop from the long cable (and power supply) and then, running off battery, hooked up to a short cable over at the modem-- the speed test jumped up to over 500mbps. Thinking a bad cable was the problem, the tech left. I put on a brand new cable, plugged in the power supply and then ran speed test again--right back down below 100mbps!
With Google's help I figured out that a computer will throttle back internet speed to compensate for an inadequate/faulty power supply and mine must have been gradually failing. The new power supply arrived today, got plugged in and guess what:

Just a thought for anyone facing the same issues.
