Infinity Speed Drop

I have had Infinity for 2 years 9 months and all has been fine until 08:07 on the 26th November.

 

Up until then I was syncing at 77 and getting an IP profile of 73, now the sync speed has dropped to 64.59 with an IP Profile of 64.97 for no apparant reason.

 

I am on the BT homehub 5 and its connected directly to the master socket.

 

I live aprox 200 meters from the street cabinet.

 

I have a SamKnows white box which backs up the speed I have been receiving.

 

Regards

 

Michael Gibson

Re: Infinity Speed Drop

connection time is only 5min is that due to manual reset or router dropping connection?

Re: Infinity Speed Drop

I rebooted the router to see if the speed would increase.

Re: Infinity Speed Drop

Done the same with me, gone from 76mb to 69mb and 20mb to 19mb up.

 

BT up to their old tricks as usual, slowing down connections.

Re: Infinity Speed Drop

BT Retaill do not control the network Anymore than SKY or TT however the more customers on your cabinet the more likely your speed is likely to reduce and especially noticeable if you were in first batch to get fibre

BT Retail control the modem remotely. What do these lines mean?

This should not affect the sync speed or IP Profile to the cabinet as this should depend upon the quality and length of the copper pair and not the number of connections in the cabinet.  Anyway this would not explain a sudden drop of 9Mbps at 08:07 in the morning.

You may find this of interest :- http://www.increasebroadbandspeed.co.uk/2014/vectoring-crosstalk-crisis

As it explains the number, and more importantly the proximity of other pairs, will affect speeds regardless of line quality.

 

I agreee that it is unlikely to be the cause of a speed drop at such a precise time, unless of course and engineer connected some new lines at that time.  So there could well be other issues. 

 

Please enter your telephone number into http://www.dslchecker.bt.com/adsl/adslchecker.welc​ome  and post the results, after first removing your telephone number.

Best regards,
