Constant drop in internet speed - Time Warner Internet

This question is about "Constant drop in internet speed", with Time Warner Cable internet and apps. I've had twc for evrything for a few months and I have to regularly reboot my modem because my speed drops to about 1.5 when I'm paying for 30. I've had two tecs here and complained till I'm blue in the face. Evidently there is no solution. I bought a second modem with no change . I asked if my son playing games on his PlayStation 3 would cause this and the twc said no. It just sucks to pay for 30 and have to reboot my modem on a fairly regular basis because it has dropped down so low .

This topic covered Constant drop in internet speed, and TWC cable internet service.
