Poor upload speed (Infinity)

Hi, My phone line/broadband (Infinity) are both working OK except for a poor upload speed (consistently low over the past year). The test/stats are given below. Generally my download speed is about 10 Mbps and upload speed about 0.5 Mbps. I can live with the download speed but the upload speed is increasingly proving a problem. I've done all the tests with a single high-spec PC connected via Ethernet to a BT Smarthub with wireless switched off and extension disconnected.

 

I've tried going through the BT helpline, but they just say everything is OK and want to refer me to the retentions/cancellations customer dept (do they want to get rid of me as a customer?).

 

The broaband availability checker shows that I should be getting between 1.8 and 3.7Mbps for the upload speed.

 

I would be grateful for any help please. I've noticed from other posts that when it is possible to speak to an engineer, they can be very helpful - any suggestions for this (without the risk of getting a large bill)?

 

TEST RESULTS

 

  1. Best Effort Test:

 

Download Speed : 7.82 Mbps

 

  1. Upstream Test:

 

Upload Speed : 0.5 Mbps

 

Your speed test has completed and the results are shown above, however during the test an error occurred while trying to retrieve additional details regarding your service. As a result we are unable to determine if the speed you received during the test is acceptable for your service. Please re-run the test if you require this additional information.

 

STATS

Data rate: 957 bps / 15.18 kbps

Maximum data rate: 957 / 17440

Noise margin: 6.7 / 6.1

Re: Poor upload speed (Infinity)

have you tried using the test socket with a filter to see if that helps by eliminating your internal wiring from causing a problem?

 

try quiet line test  dial 17070 option 2  should be quiet and best with corded phone

Thanks for the reply. Yes, I did the test using the test socket - so there was no internal wiring involved. I did the Quiet Line test with a corded phone - no hisses/crackles/pops though I think I can detect a quiet hum.

The quiet line test should be silent.

I'll try to problem-solve the origin of the hum.

 

Meanwhile, will a hum impact upload speeds?

 

One other question - from the data I posted, do you think there is something wrong with the upload speed, or should I just accept this as the best I'm going to get?

Re: Poor upload speed (Infinity)

your up speed is lower than estimated so would expect better but ISP don't appear to prioritise up speed problems normally just down speed  your down speed is right at bottom of estimate

Re: Poor upload speed (Infinity)

Thanks for the replies. Just one thought .... there is a long length of external cable going around the house to the master socket - it is over 100m. Could this be an issue - see photo below:

Re: Poor upload speed (Infinity)

the longer the cable from the cabinet to pole to house to master socket the slower the connection will be  You probably can only have a say after dropwire from pole reaches your home

Re: Poor upload speed (Infinity)

Thank you for all your replies. Based on all of the above, it would be good to hear opinions as to whether it is likely that BT can do anything to improve the speed (e.g. cabling/cabinet/equipment settings) and if so, how best to achieve this (e.g. by somehow getting to talk to engineers rather than customer "service" staff)?

Re: Poor upload speed (Infinity)

the engineers work for openreach not your ISP and they openreach only deal with their customers which are the ISPs so you can't contact them and get a reply

 

did you check out the hum on quiet line test with corded phone  if you were using a cordless phone then a dull hum is normal
