why would you need to it's part of the docsis spec (2.0 i think)
as far as i know the only way to change it would be use a docsis 1 mac (but i could be wrong)

how to change docsis 1 mac and how to change upstream mode?
i'm from hungary my isp is fibernet and if upstream mode SCDMA then ~300KB/s upspeed but, if upstream mode QAM16 then ~800KB/s upspeed, that's why i need QAM16 upstream mode
incidentally with factory firmware QAM16 use
i hope understandable write but i low speak english :S
thx for help me

i use force config this not problem, only upstream modulation with change.
Configuration file
Name unl.cfg
Size 92 bytes
Compliance DOCSIS 1.1
how to force the modem to QAM16 upstream mode?
any command in console or setting?
RE: how to change Upstream Modulation??? - drewmerc - 30-09-2009
there's no command it's part of the config that is downloaded only way to change is change the config or mac
RE: how to change Upstream Modulation??? - qweee - 30-09-2009
i not fully understand. the config into is it that change upstream mode?
because then what write in the config?
RE: how to change Upstream Modulation??? - drewmerc - 30-09-2009
the config is downloaded when the modem registers with the network it contains the settings needed to get online
the config that is downloaded is matched to the mac
RE: how to change Upstream Modulation??? - qweee - 30-09-2009
i know i know, but where in upstream mode setting?
RE: how to change Upstream Modulation??? - drewmerc - 30-09-2009
i'll say it again you need to change the config or the mac
run the program in the picture above (without a router being in the way) let it run for a while it'll give you some different configs's that you can try to force
or run the program on a differant node/ubr and it will give you differant macs to try
