Poplar exchange, bad or just plain overcrowded?

Recently moved to the isle of dogs, nearest exchange is Poplar, and am getting very, very poor internet speeds at night ~0.5Mbps and 0.1Mbps upload anywhere between 7pm-2am. 

 

Phone line has been checked by BT engineers, they say its fine. Exchange is fine, so where's the problem? Is it going to get any better?

Re: Poplar exchange, bad or just plain overcrowded?

can you post the adsl stats from your router (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z) and run btspeedtester http://speedtester.bt.com and post the results. Someone may then be able to offer assistance

Re: Poplar exchange, bad or just plain overcrowded?

I noticed the reporting tool is by plusnet, would the results reported by plus net be related to the performance of bt broadband? Shouldn't it just be the portions leased out to plusnet that plusnet is reporting on? Just a guess, I've no idea how BT works this arrangement out.

 

I was under the impression that all ISPs in the isle of dogs are equally bad because of the Poplar exchange.

Re: Poplar exchange, bad or just plain overcrowded?

the results given by the usertools checker of plusnet is reporting on the virtual paths at the exchanges, if any isp uses bt wholesales network to transport there data from the end user to there gateways then this checker gives you info you need to find if congestion is occurring at the exchange level

 

am not sure if a ppp drop and reconnect would enable the OP to try and find a less used VP pipe at the poplar exchange that currently is in amber status, i do know that if an isp's gateways have unblanced customers across them then you can do this to find the under used and better performing gateway.

 

the only other way i know from my experience of being a PN customer is to add max premium to your connection at an extra charge of about £8 a month which gives your connection more priority over the VP pipes and bt wholesales network upto the isp's central pipes(gateway) this only apply's to 20cn connection's and not adsl2+ 21cn connections and max prem also gives you a 834kbps upo sync instead of 448kbps

 

EDIT.

if your on a 21cn connection the the VP checker does not report on vlan capacity pipes that 21n uses, so is useless if you are on a 21cn connection
