Slow internet

"Slow" with wired or wireless connections (or both)?

What are the download & upload speeds supposed to be for your level of Comcast service?

Test at different times during the day:

Test with just the broadband modem.
Test with the broadband modem & router.
Any difference?

Use latest router firmware (if using a router).

In some cases, the broadband modem is at fault and needs to be replaced by Comcast.

If it's not a result of a P2P program you have running or spyware, odds are it's just a natural function of cable Internet. It's SHARED bandwidth, so you and everyone else on the same hub as you, share that hub's total bandwidth. The more people on the hub, the less there is to go around. If you don't like this, I suggest looking into DSL service in your area, which is dedicated bandwidth.

Go to and run a series of their tests and you can tweak your system with DRTCP etc
There are valuable informational articles in order to get the most from your resources

I didn't think that my computer was slow, but I ran the speed tests form the various sites anyway. All the various test sites had me down in the range of 1994 kbps download speed and 361 for upload speed with an RWIN set to 17520. I ran the zip file provided by DrTCP and set the RWIN to 64240. Reran the speed tests from the different test sites and now they all were above 3650 kbps for download speed. I have a Dell 2350 windows XP SP2, 1GB, 2.0 GHz, Cable Modem with Time Warner Cable/Earthlink. with the usual antivirus, antispyware and ZA firewall.
Thanks again,
