Last week I upgraded to 100MB connection and a Superhub 3. I am pleased to say that the new upgrade is delivering good speeds of 100MB. However, when I log in to my VPN (minutes later), the speed reduces to 10MB.
Previously, I had a 70MB connection and a Superhub 2, I haven't speed tested it recently but I am sure it was much better than 10MB. I say this as I never had any problems making Voice over internet calls. Since the change, the calls keep cutting out and getting delayed.
