Whilst waiting for VM to respond on here - are you saying your speeds have actually been reduced to 125?
Can you check by logging into the Hub settings and going to the Configuration Data page. Then in there, what numbers are present in the Downstream and Upstream boxes for "Max Data Transfer Rate"
Can you post that data up here - note that the numbers are in bps not Mbps.
