C3000 Unsatisfied
I am thouroughly unsatisfied with the Netgear C3000 Cable Modem/router. We purchased this in June and have had problems with it since then. We have been working with Comcast all along to fix the...
You haven't described your problems, though it sounds it at least involves Wi-Fi speed. Are your wired devices also affected?
Has Comcast looked at the signal levels coming into your C3000? Are they low? If so, has Comcast sent a tech to test the signal and inspect the cable coming from the cable plant to your house?
Do you have coax splitters between the cable demarc (i.e. the point where cable enters your house) and your modem? If so, remove all of them. A 2-way splitter will cause a minimum of 3.5 dB of loss. 3- or more-way splitters are even worse. And unterminated cables will cause reflections that will degrade signal integrity.
Have you measured the Wi-Fi signal strength on your devices? Apple has a Wi-Fi scanner built into their Airport Utility app that will report signal strength. You can find instructions here, about midway down the page, for enabling the scanner.
