Hi Guys
I have a problem and wonder if any of you can shed some light on it for me.
I had a perfect 50Mbps service which I upgraded to 100Mbps. After the upgrade my download speeds start off relatively quickly but rapidly slow to a snail's pace.
I had no joy from virgin and asked to be put back to 50Mbps. But now I have the same problem with 50Mbps. Downloads from business sites with very large pipes.
When I start a download I achieve around 4-5MBps but this rapidly drops to 1MBps - 400KBps - sometimes less.
Apple TV was able to download movies in a flash and now I have to wait and wait.
During the upgrade I had a new Superhub. I also and a 3 way 6db splitter fitted in the omni box and a Tivo Box installed in another room.
The Superhub is configured in modem mode and I've tried two new routers -DLink DIR-855 and Netgear WNDR4500.
The stats from the modem seem to appear ok -
