Faulty ADSL connection, things to check:
- Try turning the ADSL router on and off, if necessary unplug the
transformer, this cures more than 50% of speed problems.
- Check there is no noise on the ADSL line. To do this make a phone call
using the faulty line to someone and ask them to be silent and listen

- Check you are connecting to your own wireless router. A surprising
number of people accidentally connect via neighbours wireless routers.
- Check the aerial on your PC is not shielded. Close proximity of a steel
table leg can be a big problem.
- Check the aerial on your wireless card has not become unscrewed or
