I am running a cable modem that runs real close in several bandwidth tests to a T1 connection but cannot get my upload speeds to go past a combined total of 21 Kb/s. I have my upload speed set at unlimited with a max of 2 uploads at a time and have uploaded several files and never have I seen it go past an upload speed of 21 Kb/s. My question is can I tweak a setting some where to up this value or is this the max. Thanks for any help.
