Hi,

I moved from Sky Fibre Unlimited Pro to Plusnet 80/20 last month. I used to get download speeds of around 66 Mbps with Sky but they tended to be around 54 Mbps when I first joined Plusnet. I changed the modem from the ECI supplied by OR to the HG612 which gave me a 2 Mbps boost. After complaining a few times to Plusnet they said it's within tolerances.

According to the BT Broadband availability checker I get the following:
FTTC Range A (Clean): 66.9 - 80 Mbps
FTC Range B (Impacted): 56.9 - 80 Mbps

I telneted into the HG612 modem and got the following:

The max downstream is 70652 Kbps but the bearer is much lower at 61451 Kbps. Even with that, I would imagine a speedtest would be closer to 60 Mbps than 55 Mbps assuming overheads.

Any thoughts as to why I'm getting almost 10Mbps lower than I did with Sky? It's really puzzling me.

[Dray]

Possibly due to the absence of G.INP on your connection.

Are you on a Huawei cabinet or an ECI?

[joemcd]

I'm on a Huawei cabinet.

[Dray]

Does your HG612 have the latest firmware which supports G.INP?

[joemcd]

Yeah it does. Firmware version B030SP08

I experienced a similar issue moving from BT to Plusnet in May which should hopefully today be resolved by an engineer.

On BT I was DSLAM banded 80/20 with a IP Profile of 65/20 after the migration took place it changed to a DSLAM banding of 74/17 and my IP Profile suddenly dropped to 56/20.

I've managed to finally convince Plusnet this week that this is wrong so a DLM reset is scheduled for today to fix this. Ask Plusnet for your PTTR & GEA service test results which will highlight your IP profile and your banding.

[joemcd]

Oh very interesting. I just contacted them with that. Let's see what they say.
I hope your DLM reset solves everything for you.

[joemcd]

Just a quick update on this. After some complaining to Plus Net they escalated it to Openreach. They did some "remote work" on the line and now things are back to what I was getting with Sky.

[roseway]

That looks like a result.

[Bald_Eagle1]

The improvement may be linked to the fact that Mk2 G.INP is now active on DS on your connection.

[NewtronStar]

Yes Bald_Eagle1 i think Sky has had it own G.INP well before us BT wholesale users 

[GigabitEthernet]

Yes Bald_Eagle1 i think Sky has had it own G.INP well before us BT wholesale users 

The actual service is identical though - it's all Openreach provided infrastructure. It's the back-end that is different.

[NewtronStar]

Yes but the difference is SKY is LLU'd it has it's own DLM equipment at the exchange and BRas profiles at the back end.

[burakkucat]

Yes but the difference is SKY is LLU'd it has it's own DLM equipment at the exchange and BRas profiles at the back end.

No. The DLM is the same for all users with a service provided via VDSL2. The service is carried over the fibre to the head-end exchange. At that point, the Sky users' service is "handed over" and then it becomes Sky's business as to how they treat it/control it.

Sky has had G.INP well before plusnet BT EE and talktalk is that incorrect ?
