In reply to a post by Anonymous:Hatch Warren getting 37.4 meg down, although engineers machine said 40 meg max ? couldn't explain why,
I've also not gone through the supposed 10day flucuation in speeds until its settled mine has stuck at 37.4 thoughout.
The 10-day thing is a myth - especially for FTTC. Openreach's documents state that DLM will monitor for the first day, and intervene if necessary on the second day... unless things are dire, when it will intervene as fast as possible.
The first question is... what is the 37.4 meg? Is that the speed seen in a tester like speedtest.net?
If so, then that *is* about the best speed you can get with a 40Mbps sync.
