BT infinity 1 Speeds on BT Infinity 2 - 74Mb actual dropped to around 34Mb.

A few months ago we purchased BT Infinity 2. The Infinity checker online stated that we would receive around a data speed of 76Mb. For the first two weeks it was hanging around 74Mb and was quite chuffed. After that I didn't bother checking for a while, until one day when I just thought I would. It had dropped down to somewhere 56Mb and i had posted at the time.

 It has now dropped to 34Mb at the lowest I've seen, and some usages of BT Infinity have been buffering.

 

I have run the various test below. Any help appretiated.

 

Line Noise Check Results - Slight constant crackle, although no other background noise.

Area Problems (Service Status) - None reportd by BT

you need to report the line noise on 151 with no mention of broadband in the call

Re: BT infinity 1 Speeds on BT Infinity 2 - 74Mb actual dropped to around 34Mb.

Hi John,

 

I have managed to get hold of a working wired telephone handset, just to test the line before I call BT and get them to come out. The line seems clear now. The previous handest was cordless and could have been interference from another source. Looking at the other tests, do you have any other ideas for this speed drop?

Connection time is only 2+days so it may be if you have not been checking that your router has been dropping connection which would account for the higher than normal 6db noise margin

 

have you tried using the test socket with a new filter and see if that helps improve your connection. You may have a SSFP but using test socket eliminates a problem with the SSFP and also your internal wiring

Hi Imjolly,

 

 The conenction time of 2 Days is me. I have just checked the HH5 log and there are no issues with any connection time. I have also checked the test socket and tried a new filter. Also re-run the tests and the results are exactly the same as the ones posted below.

 

 

(SSFP)

Just for clarification I have the I-Plate version and have microfilter at socket points around the house. The test socket is behind the I-Plate.

Sorry but if no drops in connection apart from your reset then how did you get a lower speed as you would need a drop in connection before reconnecting at lower speed

 

posting router stats from test socket would help as that should be your best connection. If still low And no change in noise margin with quiet line test ok then you need engineer visit

If by "you" you mean you have been resetting the Hub then STOP! VDSL is different to ADSL and doesn't like resets too often. It could cause DLM to intervene and raise your noise margin and/or put you on interleaving.

pippincp / imjolly,

 

 I meant "Me" as not the HH5. I leave the HH5 alone as much as I can. We had a power cut here 2 days ago, which has caused more than likely caused the reset of the connection time.

 

Not sure if I was looking at the correct info on the log but have noticed the following:

 

20:02:32, 18 Sep.

( 145.180000) PPPoE is up -​ Down Rate=38274000Kbps, Up Rate=19999000Kbps; SNR Margin Down=12.2dB, Up=7.2dB

 This is the extent of the log, if it would go back further it would of shown where the down rate was comparable to our original 46 Mbps.

All the reset see the cause of your drop in connection. Line appears more stable now so hopefully if you maintain connection with no manual resets the DLM will start to reduce your noise margin and increase your connection speed. Unfortunately this can take a few weeks but is automatic

You just have to look at the SNR down margin reported.
