Ive changed a few things around already under command prompt that were in the windows 7 tweaks but my downloads seem to shoot up to like 3 4 or 500 kbps than drop down to anywhere from 25- 50 kbps and stay right there around 25. I was also wondering what is the best browser to use in SpeedGuide.net eyes? Ive used chrome, internet explorer, firefox and opera. From what I noticed chrome seemed to be the fastest and browsing but downloads were about same as usual. Also im on a 90 Mbps Comcast connection just checked it and got this.« SpeedGuide.net Speed Test Results »

Any help is greatly appreciated thanks for your time.
Trying to Speed up my downloads
I use Chrome personally.
You may also want to try speedtest.net, as they may have more servers closer to your location and give you a more accurate reading.
For tweaking, try the TCP Optimizer, just use the "Optimal" settings for your advertised speed. You are right that this does not look like a 90 Mbps connection, it may be worth checking your cable modem signal levels (usually accessible by typing http://192.168.100.1 in your browser).
Here is what the signal levels should be:

Ive found Chrome seems to be the fastest browser ive found, with those numbers up there I do have 1 splitter in line going to my modem and to my dads tv in his room I have the splitter grounded plus there is a ground post that the cable goes through as it goes into our roof area. What should I eliminate? Thanks for your reply im gonna check all the connections and make sure they are good and tight.
You probably shouldn't eliminate anything, you can try changing the splitter if you want, as there is some noise on the line, but it could be anything. A good indicator would be the speed tests.
About your signal:
Your downstream power is in the upper boundary of what is considered normal (strong signal). However, your upstream power is also very high, meaning your modem has to transmit very "loud" to be heard at the head-end, usually because of noise on the line.

Ok so the last 2 days I was outside messing with the cable line into the house and after going back and forth multiple times today I hooked everything up basically the way as before. Basically I think what my problem was is I was trying to shorten up my cables that are running into the house and my room so there wasnt like 20 feet of slack coax just laying under the house so when cutting the cables shorter I was trying to reuse the old connectors by pulling out the cable and disassemble and put the new in well I wasn't getting them connected the correct way so today I cut the cable on the last hookup I had to to do going from the 1 splitter outside into my room directly to the modem and made sure I cut the lengths exactly as specified on how to hookup a coax connector and I ran the cable directly into the splitter and wrapped the frayed grounding wires around the outer edge where it would screw in usually and taped it up good put everything back turned on my pc and got these. consistently.Philip wrote:You probably shouldn't eliminate anything, you can try changing the splitter if you want, as there is some noise on the line, but it could be anything.

A vast improvement from where I was ive been getting that download speed for the last 6 hours so im on the right track I do appreciate your help though it gave ideas on what to look for to diagnose the problem. Thanks again
My last question is to fix my upstream power to get the noise out of the line better would I just go back to all the connections and make sure they are super clean? I really wanna do away with the 1 splitter I have on the line but would a coax tap be my best bet or are there any other ways around a splitter to get 2 good lines in?
You don't need a tap since your incoming signal is strong already (+10dB, where the ideal is between lets say -10dB and +10dB). A tap would increase the signal further, which is not better. You are better off with a high quality splitter because of the strong incoming signal.
To improve the upstream (by reducing the power level required to transmit), you could try to make sure all cable ends are well terminated, not oxidated, and without the possibility of water getting inside the connectors/shielded wire. Even a bit of vaseline on the threads can keep water/oxidation away from the connectors. You should also avoid any unterminated cable ends (where the conductor wire is exposed/unshielded).
