Tweak Help + unconstant speed

[buckie2o5]

I'm using Window XP Pro with SP2 installed.  My internet provider is Comcast and I recently bought the 6 mbps down package and my internet is running through a router.  I have two problems with my internet.  First is that the speed is unstable and secondly, my speed isn't reaching half of the speed that Comcast advertise.  Everyone is so friendly in this forum so I hope somebody could help me out. 

Problem#1

I downloaded CableNut and  the file VanBurens_cablenut_settings_version_7_ALL_WIN_OS_AND_SAT.  I unziped the file to C:/Program Files/CableNut and I followed the instructions and saved the settings to the registry then restart my computer

My speed was slightly faster after the tweak, but the internet speed was still unconstant.  The speed is always the fastest around this when I turn on or restart the computer on an average:

It's not often that my internet speed reach the basic plan (4 mbps package) so reaching the 6 mbps down package that my parents bought is out of the question (my dad told me that he had paid for that Comcast Tier for about a month already).

 

Problem #2

Then after a few hours from the time I turn on the computer, the internet sorta slows down.  For example, after I was done uploading a video clip at yousendit.com (which always fail upload for some odd reason), the speed dropped to these speeds and doesn't go back up unless I restart the computer again (I've already read this thread https://testmy.net/topic-4257 and I made sure that my computer wasn't affected by disk-errors, spywares, adwares, etc)::

I was wondering, did I apply the settings incorrectly to have cause these two problems?

I got the problem with not reaching the speed that Comcast advertise fixed.  It turns out that there was some miscommunication when asked my dad what internet plan we were using   

But I'm still experiencing problems with unconstant speed.
