Also, you may want to try you speeds on different sites. You're only as strong as your weakest link and if you can download 12mb/sec and you try to download a file from someone on a 56k modem, i somehow dought you'll get you top speed.
ALso Comcast will sell it as UP TO 12mb\s so it can be anywhere up to that speed ! - to test your actual speed run several speedtests to different sites and see what the maximum speed and avg. speed you get - If it never gets anywhere close to 12mb\s then call Comcast and tell them what speeds you are getting and see what they say about it.
for example I'm on AT&T's U-verse MAx which is 18mb\s download and 1.5mb\s upstream and here is my latest speedtest result :
I'm happy with it. Decent for $30 i-net in my small town.
Yea - speed boost is nice if you do alot of small downloads since it will make a big difference in the download time unfortunately the boost only lasts a short time so on larger files it only helps a little.
we pay $55 a month for our service @ 18\1.5 which works great for us with 3 computers using the connection most of the time the slower services just couldn't keep up when you have 3 systems all browsing and downloading things so was worth the extra cost.
I see far more Acer, HP, Compaq, and Dell Notebook in my shop for servicing than I do Toshiba or Lenovo products. Then again, this might just mean there is a greater volume the other brands in my area in general.
