Poor WiFi speed compared to Ethernet

I have been having intermittent speed problems ever since I have purchased this unit. If I attach my computer via Ethernet, the speeds are above what my contract calls for - 50 mpbs. If I link up via wifi, the speeds fluctuate anywhere from 5 mpbs to 75 mpbs. The latter is a rarity.
My household links everything via wifi but there is never more than 3 devices at a time using it. In fact, I can't even link our MacBook Air to Ethernet; it has to link via wifi to the Internet. Also, all our other IOS devices. I have tried everything, changing channels, plugging and unplugging, calling my cable company (Comcast says it is your problem). I am getting frustrated being monkey in the middle.
Please fix this problem or at the very least, give me a credit so I can go out and buy a new device (I purchased this last year).

Have you taken survey of nearby Wi-Fi networks and eliminated any sources of radio interference (e.g. baby monitors, 2.4 GHz cordless telephones, microwave ovens, Bluetooth devices, wireless speakers, etc.)?

The only thing we have is the microwave and that was niot in use. I tried changing the channel again and switched from auto to 6. It seems to have increased the speed considerably but I will continue testing for a couple of days since this has been tried before and worked only temporarily. Thank you you for your response.

Well, you should probably run a Wi-Fi analyzer and take stock of what Wi-Fi networks are active around you and the channels they are using. Then pick the least used channel. There are plenty of free Wi-Fi analyzer programs that you can download. Netgear's Genie program even has one. Pick one and try it.
As I mentioned further above, switching to 5 GHz can dramatically improve speeds. I'll recap the options:
- Replace the C3000 with a dual-band router/modem
- Add a dual-band router and put the C3000 into bridge mode
- Add a dual-band Access Point
