Upload speed Issues

I've been having issues for a couple months with my upload speed dropping. I had a tech out today and he resolved an issue in the line and fixed the power levels on the modem, but the upload issue still persists. After he left, everything worked perfectly for an hour before the upload speed dropped back down to under 1mb/s. I enjoy streaming online games and an upload speed that slow is unacceptable! Before today the power levels on the downstream bonded channels were -22 -  -23 with high codewords on certain channels. Now I'm curious about the Downstream OFDM. I don't know the range it's supposed to be operating in or what effects it and don't know how to fix my issue. I think I might have the wrong firmware on my modem as well. On my end it's Firmware Version V6.01.07, and from what I understand it's supposed to be 3.01.04? Should I factory reset my modem? I have Gigablast with a Netgear cm1000 modem.

Could the issue be old wiring coming into the house? I'm running out of patience and if I have to deal with customer service one more time I might lose my sanity.
