FTTC speed query


[link to this post]
 
When looking to upgrade from copper to FTTC for my broadband connection I noted that the provider I had selected indicated "download speeds of upto 40Mbps with upload speeds of upto 2Mbps" for home broadband

I then used the same providers speed checker and this indicated an expected speed od 28.9Mbps down and 5.7Mbps up.

When the installation was completed I checked with speedtest.net and found that the actual speed was around 20.65 Mbps down and 1.7Mbps up. the latency shown on speedtest was around 13 and 14 milliseconds.

This has since dropped to around 15Mbps down and 1.7 up with a latency normally around 22 milliseconds.

Sync speed shown on my providers control panel was originally 21438 and has now dropped to 15728.

I have complained about the current speed but they tell me that it is within reasonable limits.

Do you think it is reasonable, or are they trying to get out of providing the service they advertise? The speed test they provide is still showing that 28.9Mbps down and 5.7 up is possible.

Alas with FTTC the speed you get is largely determined by the length of the line between the cabinet and home.

The original 40/2 is the headline speeds i.e. those closest to the cabinet will get.

Half way down the page is a rough distance/speed guide. From your post does a distance of 1000m (1km) sound reasonable for line between house and the green fibre street cabinet?

All the estimates given are connection speeds, so yes speedtests will very often be lower. Though to date most people getting FTTC have got speeds above their estimates, the key word though is estimate.

You can try and exercise consumer rights and walk away, but to be honest no other FTTC provider is going to do better as the physics are the same for them all.

The downstream drop looks a little odd, but re the upstream you appear to have purchased a 40/2 product not a 40/10. In which case the 1.7Mbps real upload is spot on for the 2Mbps sync.

Guessing but the latency rise, may suggest the DLM was seeing errors and kicked in with a slow down and more interleaving

Ask the service provider if that is within Openreach tolerance - they have number for sync speed reduction beyond which it is regarded as a fault.

FTTC Speed Estimate


[re: MrSaffron] [link to this post]
 
Can anyone suggest what my connection speed might be when my cabinet gets fibre connected later this month? I'm just over 1 km from the cabinet, and the cabinet itself might be around 6 km from the exchange.

Many thanks

According to http://www.thinkbroadband.com/guide/fibre-broadband.... about 24Mbps but these numbers are pretty pessimistic. The distance to the exchange is completely irrelevant.

Thanks Kevin. When you say numbers are pessimistic, any idea what a more realistic figure might be in terms of a percentage under-estimate?

Not really, as different people have different experiences so I can only speak for myself. I am about 450m from the cabinet and currently sync at 72Mbps, the table estimates between 38 and 42, I would say the majority of people at a similar distance exceed that.

I believe you are on BT Broadband. If so, put your phone number into this checker and that should give a range of possibilities.
