I have Comcast HSI and I even upgraded to their blast speed. In June I also added their digital voice home phone service so I now use their modem. The woman told me that my speed should be even faster because of using this modem.

I have a desktop computer and my roommate has a laptop so I also have a router connected to my modem so that she can also use Comcast HSI. Like I said before, I usually don't go online during the afternoon or early evening hours during the week because I'm at work and I don't have access to a computer. I usually go online at night or early in the morning. Since a lot of PT'ers are on the east coast they aren't online when I'm on at night.

When I was having problems, I noticed that there were quite a few people online at PT so maybe this is why I was experiencing such a slow speed. Supposedly with cable it shouldn't matter when I go online because it should always be fast but I still have my doubts about this.
