I've been on Virgin Media 50MB since it first came out and everything was good for the first couple months but now also I'm noticing these fluctuating speeds.
Can someone please look at my downstream and upstream which you have talked about and can you tell me if anything is wrong here with the results?

I have had 2 Virgin Media Technicians round one being a senior and they told me that there is nothing wrong with anything in the house i.e the modem etc. I am directly connected to the 50mb modem but notice this weird fluctuating speed on 50mb, it's not as good as it was before and you can physically see the bursts and drops in speed and also places like speedtest.net are showing inconsistent speeds.
