If I could ask the same but with a different slant?
My Infinity1 has always been (ignoring past issues) 40Mb.
My account shows the 'new' cloud storage limit.
How can I tell if the upgrade is under way?
By the way, the FTTC check has always shown a max (clean) of 32Mb!
I have moved you onto your own thread so that your answers do not get confused with the Original Poster of the thread you posted on.
You will probably not see any improvement in your speed. If your estimate is 32 Mbps you are lucky to be getting 40Mbps.
