Re: BT Infinity Same Speed As ADSL

Thanks for those line stats - I can see you have a long line from the attenuation.

Your IP Profile is set from your Data Rate (sync speed) and only changes when the modem resyncs with the cabinet.

If you could post the line stats again, we may be able to see what's changed

imjolly, out of interest how do you read the graph that you posted? Is that ADSL/FTTC performance from the cabinet or is that ADSL performance over the entire copper leg and VDSL over the copper leg from the cabinet? The reason I ask is because I estimate that my distance from the cab is about 2.5km. The distance from the cab to the exchange is then roughly another 1.6km. I know my performance for ADSL, so just trying to compare the performance estimate for FTTC. (And yes, I know that we don't really know how long the Exchange and distribution legs really are - but I have to try and work with something).

 


Hi odwyrpaul,
This graph might be a little clearer.  As you say with ADSL it is the distance from the exchange, with FTTC it is the distance from your cabinet.

Generally, to those that responded, is the consensus that this is tough luck, I just happen to be the distance away where ADSL/FTTC performance is pretty much identical? My only other question was relating to IP Profile. On ADSL my IP Profile was 4.77, since activating FTTC this value has never fluctuated from this over the course of the speedtests I have completed this week. Could I be capped in some way?


as I said in the post the graph shows the adsl speed based on distance from exchnage to your home where as the vdsl2 speed is based on distance  from cab to your home

Re: BT Infinity Same Speed As ADSL

Thanks ray_dorset. I have perhaps confused the issue, unfortunately nothing has changed since the FTTC install.

 

Pre-FTTC Install (so when I was on ADSL with BT)

 

DL Speed: 4.48 Mbps

UL Speed: 0.38 Mbps

IP Profile: 4.77

 

Post-FTTC Install (Completed on 8/9/2014)

 

DL Speed: 4.62 Mbps

UL Speed: 0.35 Mbps

IP Profile: 4.77

 

I think I will just speak to Customer Services at BT to see what they can do, if anything. It is the fact that there has been so little comparable difference, and no change whatsoever - neither lower or higher - during this "bedding in" period. It's as if the install was completed but the system thinks it can still only deliver 4.7 Mbps. Perhaps I am just in the sweet spot where the performance via FTTC and ADSL are exactly the same, it just seems a big co-incidence.

Re: BT Infinity Same Speed As ADSL

Sorry, I wanted to see your line stats again -Can you post your line stats from the HH5 please? These are in Troubleshooting/Helpdesk on the web interface at http://192.168.1.254

Lines 1-13 will be enough

6. Data rate:419 / 4934
7. Maximum data rate:390 / 2643
8. Noise margin:4.5 / 8.1
9. Line attenuation:0.0 / 46.6
