Well all sorted, no thanks to Bullitt telling us all that its an estimate and tough luck if you get 1mb on an up to 76mb link.
Engineer visited, the previous engineer who installed the kit had piggy backed the houses interiotr cat5 cabling, that unfortunately by the time it got to the port I was using was running close to the 100 metre limit of cabling.
Dicsonnected the cabling at the main port and installed a data forwarder, now getting 65mb down and 15/16 up on my estimated 68.8/20.
More than happy, my IP profile states 74.3mb up and 20mb down so the moral of this is, dont listen to Bullitt, get a case logged with the BT guys on here and they will do everything they can to help you, sometimes there is an issue and if you try hard enough, you get it sorted.
Thanks everyone except Bullitt for their help, pointed me in the right direction as asked and problem solved as hoped.
No you said the wiring type and length to the cabinet, this was not or never was the issue, the junction box is 170 yards from my house and the exchange 1 mile from the junction box.
The issue was not installing it correctly and piggy backing the internal wiring in the house, but hey, thanks for playing better luck next time.
No the main BT socket in the house, the cabling in the house, sweet FA to do with any factors outside of the house........................ARGH you are the most annoying **** I have ever met on a forum.
You are wrong, you were wrong, so leave it, you were of no help, just think you know everything!!! No doubt some 'network' engineer somewhere who braindumps his was through Microsoft and Cisco exams yet couldn't subnet for his life!!!
**** off, seriously, just go away, you have not got a clue.......
The route was knocking on for 100 metres of CAT5 cabling before hitting the HomeHub.......with no router in the way the throughput was stretched, it has nothing to do with noise on the line you *** it's simple cabling limits!!!
ARRGHHHH! I give up, you are the oracle, the rest of us are obviously wrong..........douche!
