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...
Sorry, I'm not all that tech inclined.
We have low wifi strength. We pay for up to 105, and get 75-85 wired, but wifi is 1-3. We often have dropped signals.
We did have a tech out, he said everything was fine, but I do doubt his abilities somewhat. He said he needed to go into the attic to find where it came into the house. Our attic access is sealed and has never been entered, we showed him where it came into th house, and he said ok.
I have only done speed tests, no strength tests.

Give the Airport Utility a try. It's free. Use its Wi-Fi scanner to look at the RSSI of your Wi-Fi network. RSSI is expressed as a negative value, so larger values are worse. You want to aim for an RSSI of, say, -75 dBm or better. -50 dBm would be great. -40 dBm and you're probably standing next to the router.
On the opposite end, if you are seeing values like -80 dBm or -90 dBm, then either the router is putting out a weak signal or you have too many walls absorbing or reflecting the signal. Because of the high radio frequencies, Wi-Fi is notoriously sensitive to the physical surroundings. Moreover, the wavelength of a 2.4 GHz radio signal is about 5 inches, so even shifting by a few inches can affect signal quality.
