Re: Unlimited Faster Broadband - is there a "hard" downstream speed limit?

You're absolutely correct that all of the improvements have been under my control, but there's generally been a lag between making the improvements and DLM acknowledging that things have improved and allowing me a higher sync speed.  If I was at 6(ish) dB SNRM I'd accept that my line was never going to support a higher sync speed...but as the SNRM is significantly above 6 dB, with very low ES and no retrains, logic suggests a higher sync speed should be possible.  I'm just trying to understand if I can get that higher sync speed by waiting for DLM to act (although it's been a month already since the last step up) or, if I've hit a hard-limit for my current service, by switching to Infinity 1 to remove the limit.  (And I recognise I'm in the realms of diminishing returns as I've never going to get more than a slight improvement until ADSL goes away and Openreach can crank up the power).

Re: Unlimited Faster Broadband - is there a "hard" downstream speed limit?

can you post router stats

 

bt don't seel infinity 1 where speed is less than 15mb but they sell faster broadband  if you are lucky like some then you are able to get a speed faster than 15mb and spme even into the 20's

Re: Unlimited Faster Broadband - is there a "hard" downstream speed limit?

Bt no longer make a distinction between Unlimited Faster Broadband and Infinity 1.

Interesting that BT aren't offering the 18/2 profile.

Re: Unlimited Faster Broadband - is there a "hard" downstream speed limit?

so noise margin higher than normal 6db so if that reduced to nearer normal then that would give you a bit more speed nearer attainable  just need to maintain connection and wait for DLM reducing noise margin and hopefully raising speed

 

only way to get DLM reset is by engineer visit for a broadband fault and the fault being fixed then engineer can ask for DLM to be reset

Interesting that DLM hasn't enabled G.Inp on your line, are you connected to an ECI cabinet?

Re: Unlimited Faster Broadband - is there a "hard" downstream speed limit?

The 18/2 Package was trialled to try to persuade people on 21CN who lived within spitting distance from the Exchange to move over to VDSL.

Most said they wouldn't switch to VDSL as they were happy getting 16mbps and didn't want to, or couldn't justify paying extra for VDSL when they didn't need it because contrary to popular belief not everyone wants or needs Superfast Broadband.

BT/Openreach brought out the 18/2 in the hope they'd make the swap and it would look good on those Broadband Reports that shows X amount of people have swapped onto Fibre.

Also they wanted everyone on VDSL/G.Fast/FTTP soon because they want to scrap Exchanges and put people on Naked DSL. Although that might end up dead in the water because the LLU Providers are kicking off that it'll be unfair. 😒
