I changed from Sky to BT in May. The Sky router was giving 4.3Mbps download and 0.7Mbps upload. After disconnection and re-connection (new phone number), my new BT Hub3 router gave me 3.5Mbps dowload and 0.38Mbps upload. After a few weeks it started to have an intermittent fault and BT sent out a new router to replace it ... a BT Hub4.
Suprprise surprise! The new router gives 2.5Mbps download and... 0.1Mbps upload. This upload speed means I cannot work from home any more because I cannot make voice conference calls over the internet.
I am in a rural area on a copper line 2 km from the exchange. Neighbours have noticed no degradation in service. I have tested the speeds at various times of the day and at weekends but mainly at 6:00am. Upload speeds have intermittently been up to 0.3Mbps (weekends and early mornings). On Sunday, I tried the old BT Hub3 (which I haven't sent back yet) and it improved my download speed by about 0.5Mbps but upload was unaffected. No difference when testing from different devices, ethernet or wireless, using the normal socket or test socket on the BT master socket. Also no difference between different servers - Douglas, Carlisle, Newcastle, etc.
DSL noise margin varies between 7 and 14 dB upstream and 5.4 and 6.2 downstream
DSL line rate varies between 256 and 448 Kbps upstream (normally 448) and 3008 to 3616 Kbps downstream (normally about 3300).
This morning it was running at 3.34Mbps download and 0.25Mbps upload when I ran diagnostics. It showed Max achievable download speed 4Mbps and max achievable upload speed 0.45Mbps.
BT technical assistance on the phone take forever to answer and don't seem competent so I wonder if someone can help?
I want to go back to Sky - they tell me that in my exchange Sky does not rent equipment from BT but has their own so that might explain the difference (but BT says it is not true). BT also want to penalise me for breaking the contract although I calim that a 0.1Mbps is not fit for purpose.
While I could live with BT providing 56% of the download speed that Sky achieved, I can't cope with 14% of the upload speed because Skype telephone conversations are unreliable below 0.1Mbps. There seems to me to be possible solutions: (a) When I was re-connected the copper wires or connection are faulty so BT Openreach could try an alternative wire or re-do the connection. (b) Both BT routers are faulty (c) BT are throttling the upload speeds.
The amount of time I have spent on this is incredible 
so I would be really pleased if someone can help.
Thanks!
welcome to the BT community forum where customers help customers and only BT employees are the forum mods
your three assumptions - a, b, & c - are incorrect and the slower up speed is due to being in adslmax whereas sky was an LLU provider
in order for the forum members to help please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router). must be done with wired connection
can you enter your phone number and post results remember delete number https://www.btwholesale.com/includes/adsl/main.html
are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem
