Thanks Kevin at cloudscape for sorting this, speed profile was changed, and DLM reset and speeds are back to what they were.

anyway I must say I'm impressed with the throughput on the VR900 - kicks the [censored] out of the asus - getting wireless speeds as fast as the actual connection, whereas the asus wouldn't even come close most of the time.

The connection speed is now much higher as well - sitting at around 76mb when doing a speed test!!!
