Here are a few more suggestions:
- Power cycle the Modem and the computer. Turn both off for a few minutes, turn them back on, and try browsing again.
- Try disabling any firewall and/or your antivirus for a few moments to see if they are causing slow speeds.
- Check your System Tray to make sure you don't have programs like Kazaa running.
- If it was working fine yesterday or the day before and today it is slow, there is a System Restore function in Windows XP (considering you are running XP) that lets you revert your computer settings back to any previous day. That always works for me if I encounter problems.
- If you still can't figure it out, call your ISP technical support for help. That's what they are there for.
