I test the bandwidth of my broadband connection on a fairly regular basis and over the past 18 months, the downstream has dropped from 38 to 32 and upstream from about 9.5 to 7.5. This speed was verified using a number of speed reputable test sites. During this time, I believe my contract was changed by Plusnet from the 40Mbps to 50Mbps.
Testing the line with OpenReach checker suggests that I should be getting up to 35Mbps but as I am only 200metres from the cabinet and my broadband stats appear to support that, I believe my line should be capable of reaching almost to 80Mbps and I would like to move up to that plan. However, there is little point if Plusnet can't fully deliver my current plan.
