Internet speed loss, can't find solution

I'm having some serious issues with my internet speed. I am on Virgin Media 60mb with the ISP provided router. We have 4 computer connected via wires and several wireless devices. In the last month my computer has been suffering some serious internet issues.

My regular connection on speedtest.net would give 55-60mb/s, in the last month after downloading or streaming video online my internet connection would become unusable and sitting around 0.08mb/s.

All the other computers and devices on the router remain fine.

I have tried updating drivers, re-installing network devices, resetting network settings and 2 different NICs. I've also reset the router repeatedly and also tried disabling the firewall.

As a last ditch effort I re-formatted my computer and re-installed Win 7. The connection worked fine for a while until I was re-downloading some software and the connection went again.

Like I previously mentioned I have tried 2 different NICs, 1 wired and 1 wireless. The issues remains on both. I've run out of ideas.

Welcome to the Seven Forums.

Sorry that no one had any suggestions on your post back in December. I cannot think of anything for you to try - but I have asked others to stop by your thread and see what comes to their minds.

I have, it gives a ping response time of <1ms. Pinging Google gives a ping response time in the region of 35-45ms, occasionally popping up to 50ms.

I altered the ping to google.com instead of Google and it gave a different result which I didn't expect. I have attached a picture to demonstrate the issue.

This is on an entirely new Win 7 install. My previous drive was formatted and Win 7 was installed onto a brand new SSD today.
