said by StuartMW:That's great and I appreciate the clarification. So those of us that are only getting 10 to 20% of what was advertised are screwed? Mainly because of distance from the source? said by toby:
12 Mbps should equal 12 Mbps.
No it shouldn't. They provide a raw
line speed (bps). Take off the TCP/IP overhead etc and you get less.
"Due to overhead
and signaling it is not possible to download end-user data at actual advertised speeds. Depending on the type of service and whether you are served from a remote DSLAM or not you will have a minimum of roughly 12.5% overhead."
It's the same thing with hard drive sizes. First off they're always advertised in raw decimal
MB/GB etc not
computer MB/GB (i.e. a power of 2). Then when you format the drive you lose some due to overhead.
In my case the modem syncs at 12,122 so I should get around
12122 x (1 - 0.125) = 10,607
which I am.
