Sync speed allot higher than actual speed - new connection

Hi,

I was activated on NOW TV Broadband this morning (using Sky network) and I initially connected at a sync speed of roughly 49000 - this translates into a real world speed test of around 44Mbps.

Around half hour later the router re-synced at 59442 however, the speed barely increased - to 47Mbps. The noise margin also decreased during this sync from around 6db to 3.3.

I understand that as this is a new connection (from Vodafone FTTC) that the DLM will need to kick in after a few days to enable g.inp.

But what's interesting is the fact it acted so quickly after the connection went live (noise margin - and why is there now a 13mb difference between the sync speed and actual speed when it should only be around 4-5Mbps.

Speeds are the same whatever time of day and using wired connection.

Thanks.

Have you rebooted the hub since the sync speed increased? I've had similar happen with Sky's kit and a reboot fixed it.

It takes a while for your IP profile to register the new stable sync speed.

Should not be the case on VDSL2 unless an ISP is using a mirror to traffic control and has not seen the update yet.

As MrSaffron says.

Which IP Profile is that anyway? Although Openreach requires providers to limit data speeds hitting their DSLAMs, only BT Wholesale uses a method called "IP Profile".

What speed did you connect at with Vodafone, on which product?

Unless the OP lives in a Vodafone enabled exchange area, the connection for FTTC will be BT Wholesale based product and thus governed by an IP profile on the line.

I had issues with my Vodafone FTTC line on a BT exchange (only BT at the exchange) and the sync speed was 72mb, the throughput speed was 60mb for about 2 weeks, and then it began to increase towards the sync speed, hitting a maximum of 67mb.

As I read things, the OP has just migrated from Vodafone to NowTV .

No migration involved, the OP says new connection from VF with service from NOW.

Need to highlight the inaccuracy in the statement

"Unless the OP lives in a Vodafone enabled exchange area, the connection for FTTC will be BT Wholesale based product"

Sky and TalkTalk have an extensive set of backhaul links from exchanges, and thus FTTC with them does not touch BT Wholesale products.
