What speeds are you testing? 12Mbps seems to be wireless network
802.11b access speeds and not Internet access speeds, unless you are
using some type cellphone type access.
You oviously have to know something about the subject to ask the question
right. <g>
I recently got broadband from Comcast via cable modem. They describe the
service as 12 mb and say it runs much faster than that when a download first
starts.
I use a FireFox add-on called "Broadband Speed Test and Diagnostics 1.2.5"
to get the 2 to 3 mb figure. Rarely it reports as high as 4 to 5 mb.
Similar utilities show similar results.
Most any download process has a download speed readout that shows me usually
around 150 kb, altho that too rarely shows a higher figure.
Thanks
