For those using Comcast High Speed Broadband, check out the site below and read on. Comcast has been making infrastructure upgrades and that means their Broadband users download and upload speeds are increasing with no extra cost (yeah right, they'll F*** us somehow!).
If your area has been upgraded already, then go to a speed test site and do a test showing your current download and upload speeds. Then unplug your modem, router (if you're using one) and shutdown your PC. Wait about 30 seconds then turn on (in order) your modem (give that about 30 secs) then power on the router (again if you're using one) and finally boot your PC up.
Go back to the same speed test site and give it a whirl. Here are my before and after speeds (done within 15 minutes of each other):
Before: 2933 Down / 238 Up
After: 3803 Down / 348 Up
HELL YEAH! F*** DSL!
