ODCOM need to make BT guarantee upload speeds also, I have had FTTC now for two years started out with a steady connection 79Mbps 16Mbps up was one of the first on the cabinet. Well as others joined my speeds dropped completing BT speedtests I was requested to complete tap 3.. BT have tap 3 set so upload is minimum IE while testing on my ISP connection upload 10Mbps or more move to BT loggins and upload drops to around 2Mbps.
I have been gathering this data everytime I fail the tap1 test tried to point this out on ISPreview but the BT fan boys said it was not possible. Recently round at a friends they said they were having problems logging into the bt side of tap3. I did this for them and guess what on tap 3 they lost 10Mbps upload speed was hovering around 2Mbps on 80/20 product.
This does need rectifying so would be nice if others could log the speed test results date time etc then lets get this sorted BT have had their own way for far too long..
