Why is my Dell Inspiron 530 with VISTA slow on the Internet?

Medium Priority

I can use the computer on my company's comcast internet connection with no problem. When it is at home using my comcast cable modem, the speed is slowwww and I need to refresh the pages at times to get them to load. I have tested using a laptop connected to the cable modem and it works great. So is this a VISTA issue?
Watch Question


The laptop runs XP Pro, the computer is running Vista Home Premium.
Commercial and Residential lines work differently.

A Typical commercial line does not share the bandwidth like a traditional residential line so while you could be next door to someone with the opposite style of line (them having a commercial line, and  you having a residential line) you can have widely different speeds. Your connection the residential line is determined by your package AND how many others in your area are using it at the same time.


That does not explain the laptop running XP Pro just fine on the same connection.
Well though Vista is a common target to blame often it is configuration in both that is the issue. Have you updated to SP1 with vista? What kind of NIC on both computers (if one is a 10/100 and the other is 10/100/1000 that can show up as an issue even if you never reach the peak as part of the standard is more ability to handle interference).

How long have you been using your computer ? Has it always been slow on this internet connection ?

If so, your NIC card (network card) might be busted for some reason. If it is a desktop computer, you might consider borrowing or buying a cheap LAN card to test this.
This problem was resolved or you might say worked around by the following:
- Placing a 4 port internet router between the comcast cable modem and the computer

My thought is that the problem is related to a DNS problem with the comcast cable modem talking to VISTA directly.
