Would appreciate if any thinks this is the modem or Comcast. I don't want to have to pay for them to come out just to say it's the modem :(
Location: Sicklerville, NJ
Problem: Download speeds are all over the place, 5Mb-30Mb, usually make it up to 30Mb. Uploads have been really slow though, .5Mb-1.5. From watching speed tests, I can see it hit maximum speed usually downloading, then the test hangs/drops off completely. Uploads never hit above 2.5Mb EXCEPT on Comcast's speedtest. All other speed tests are slow. I remote desktop into my PC at home and it's unusable now because of the slow uploads. I disconnected my router and hooked up directly to the modem, same issue, so I ruled out the router.
