Sky Broadband Superfast Speed Query

I have FTTC broadband with Sky. It has just been upgraded to the new Sky Broadband Superfast which should give the maximum fibre speed posible. According to https://www.dslchecker.bt.com/adsl/ADSLChecker.Addre... speeds I can get are below. When it was setup 3 years after some config issues Openreach sent an engineer out who said my line was capable of 57Mbs (from some diagnostics he had run). When I check my Sky account it states When you bought your estimated download speed was 32.6 - 37.3 Mbps. Should I be capable of more? If so should Sky have requested that Openreach have my line profile changed to allow this. Accoring to my router the download syn is 39999.

If modem is connecting at 39999 Kbps then some extra speed is possible if the sync speed cap is removed, i.e. upgrade to the 80/20 product, though depending on what product you are on this may mean paying more.

The estimated speed fits in the low range estimates i.e. they were cautious to avoid over promising, so if unlocked you might see a sync of 53 Mbps but until you try no-one can predict with absolute certainty.

I was on the Fibre Unlimited product which was capped at 40Mbps. I moved to the new Broadband Superfast which isn't capped. However, I am wondering if they haven't contacted Openreach to have the sync speed cap removed because the low range estimates are under 40Mbps. I may give them a call to find out.

The 39999 Kbps sync screams you are still capped

That is what I thought. The person I spoke to said that my account has been migrated to the new product but wasn't sure if anything had happened to notify Openreach. They are going to consult a colleague and get back to me.

You have not been upgraded if your sync is still 39.9 Mbps. You may get a small increase in speed but is it a free upgrade? If not is it worth the extra cost.

It is a free upgrade.

How long ago was it supposed to happen? Were you given a date, or just told it would happen?

I have the exact same problem, upgraded from Fibre Unlimited to Superfast, the upgrade goes through within 24 hours so for me that happened yesterday.

Their estimated Line Speed for me is 34Mbps - 37Mbps with a MGALS of 32.4Mbps (where they get that from I'm not sure).

Router has me synced at 39998 kbps down even today, router stats show there's headroom in the noise margin for the 3 DS bands.

DSL Checker at BT shows pretty much the same as yourself for my line:

However according to Sky when speaking to them, my line is running above the speed range so nothing needs done. It appears that if your line is lower than the old threshold for Fibre Max (which I believe had a minimum speed requirement of 55Mbps) they won't re-profile or uncap it if you switch to Superfast, so you miss out on up to 15Mbps potentially if your line is capable of it.

Pity as BT do a 55Mbps profile, sky only do 40Mbps and 80Mbps profiles it appears.

If you were on 80/20 you would get around 50Mb.
DLM changes could potentially put this nearer 60Mb.

I've just checked Sky's website and they only seem to have 1 SuperFast tier available now.
Either your upgrade hasn't gone through at OpenReach's end or Sky choose 40/10 or 80/20 based on your estimates.

I'd be pushing for an upgrade to 80/20 if I were either yourself or the OP.
