Because they said it was an ISP issue and it clearly isn't. I'm trying to show that an ISP isn't responsible for a user's hardware or software.

Using Linux based O/S has proved that they can reach the speed they pay for. Any bit of installed software may have written something in the registry that is causing the slow down.

In reply to a post by broadband66:

The registry is just a key-value pair. More importantly is that third party security software can install software and link it into the OS, so that EVERY network interaction passes through the third party software. In the same way as a faulty driver, if that software is not programmed for performance, it can impact the super high speeds.

Most home users haven't seen these speeds before. I worry that the benefits of security software have been long left behind and now it is just money for "old rope".
