Our home is with Time Warner Cable, both internet service and cable, and our internet speeds have been slowing down over time. This happened before and I managed to fix it with resetting both the modem and router and it's happening again. Now, I'm planning on resetting everything in the next hour or two but this is very inconvenient as I last reset everything just two weeks ago. I really don't want to have to do this again in two weeks. What could be going on here?
