You can find out your current line attenuation by logging onto your ADSL router or modem and looking at a page usually labelled statistics or connection status.

No matter how many times you switch your broadband to new providers you are unlikely to make a great deal of difference to your connection if your line attenuation is too high.

The following table will give you an indication of potential speeds based on your line attenuation.

- Less than 12Db = 24Mb
- Less than 35Db = 8Mb
- Less than 60Db = 2Mb
- Less than 75Db = 512kbps
- More than 75Db+ Likely Poor Service

Of course there are plenty of factors that can cause speeds to fluctuate, including;

- Your ISP’s performance and package offerings
- Electrical Interference
- Internal Wiring Issues
- Internal Interference
- Computer Configuration
- Router Performance
- Contention Ratios
