Not sure if this is the right place for this.
I have Zen Fibre Unlimited 1 and so far it's been brilliant.
However I work from home and I connect to the office via VPN. Despite having an upload speed of 9mbps when I access the office network I'm lucky if I get a tenth of this. The IT department have asked me to find out if Zen are limiting encrypted data. I wouldn't have thought so but you never know.
If the encrypted data isn't being limited is there anywas of finding out where the bottleneck is?
