rradina posted : I don't think cable's DOCSIS bandwidth works that way. There are separate upload and download streams (frequencies/channels) and raising the upload doesn't mean you have to give up download. At some point what you say could be true. Cable plants have ~1Ghz of usable spectrum and until the combined download and upload consume all of that spectrum, changing either doesn't mean the other has to lose.

The coming DOCSIS spec has some lofty claims of possible 10Gbps over coax with a 2Gpbs return path.

Scatcatpdx posted : I am pulling this out of my head but most broadband is asymmetrical. Putting more bandwidth to downloading than uploading making the connect more efficient. Unless one running a server one dose need much bandwidth for uploading. One could have a symmetrical connection but it will cost you on bandwidth so instead of down/up of 20Mbs / 5Mbs one is left with 14.5Mbs in each direction.

Why does every provider in the US cap the upload speed at 4-5Mbs?

Because you can't do much more than that with single channel bonding.

I got a letter from Comcast today saying they upped the speed of their Performance tier to 20/4. But speed tests show that with the speed increase, the Powerboost feature appears to be gone as well.
