I'm currently on Snap ADSL2 and I tried calling Snap for VDSL upgrade. The person on the phone told me I shouldn't upgrade to VDSL because I live too far from the cabinet.
My current line status are:
What I thought strange was I was syncing at around 18000Mbps with Snap at the end of last year, and around 21000Mbps with Slingshot a few years back. I've also got a splitter installed yesterday that didn't seem to change my sync rates, so I'm guessing the problem shouldn't be down on my end.
Is it possible that I got moved to another cabinet further away from where I was?
