3.2 was normal here for upload PowerBoost - mine is now at 6mbps.

One could misconstrue this as a contradiction.

binary 0, you must be old enough to have gone to a school where the taught you to count 1-10, rather than 0-9.

Yep, your upstream is using a DOCSIS 2.0 modulation.

32QAM @ a 6.4MHz channel width = ~25mb/s of bandwidth per channel.

I pay for 16/2.

This is what I consistently get with Comcast (in Verizon FiOS zone)...

Hate to dig up an old post, but at least I searched before I posted.

Rob See Profile suggested that this testing would be done by Sept. 30th, but in the last couple of days my upload performance appears to have been increased. We are in a FiOS zone, so hopefully DOCSIS 3.0 testing is being done in the Northern Virginia area.



Here is a full 64MB upload showing fairly decent performance, and with a bit more "speed" than I have ever been able to accomplish before using the same file and test site.


Yeeehaaaa!!!!


These performance tests were done just before 9:00 PM local time.

Edit: Forgot to mention that my modem bootfile is still the same, d11_m_sb5120_speedtierextreme2_c01.cm.

so do you guys think they are testing for D3 being deployed soon. that's the only reason I can think of why they they would do this.
