some of that does not make total sense - if you were on 20 and have been upgraded to 70 then there is no way back afaik - so if you had the hub 3 on and was still getting 20 then the config file had not been sent
did you actually activate the hub3 - again if you did i am surprised they reactivated the old modem
hard to know exactly what happened without more info
Can only tell what the tech guy told me on the phone. I had the SH 3.0 working for about an hour - could get my PC working on RJ45 and a tablet working on wifi.
When I phoned to switch back to the old router the tech guy said that I was lucky I had not been switched to a 70mb line, but that the line was still on 20mb - so he was able to re-register the old VM modem. Old VM modem is working fine now, but I'm only on 20mb.
ahhh that makes more sense - the max the old modem will do is 30meg and the fact they had not upgraded you made the switch back possible - its really up to you now - if you want 70 meg then you need to get the config file sent - add the hub 3 and activate - once all thats don thats it but there will be no way back - not that you should need one - the hub 3 should work in router mode - if not then modem mode with your old router is an option - what speed that will give very much depends on your old router
