I always use http://www.speedtest.net and using the Elda server for checking speeds. My isp is currently Teletec who I have been with for 4 months now. There are a few downsides being as it’s wireless technology for instance port blocking but overall I am happy with the company and the reliability of the service. I will write up a more detailed report later.
Also I have heard bad reports about the Orange plug and surf, one lady I spoke to was in a capped 18 month contract she could not escape from and the speed was slower than dial-up
This is a test for my 1 mb connection
