Netgear C3700 Wi-Fi Cable Modem Router N6000

I had huge reservations before making this purchase because of the mixed reviews. But I took the leap and bought it. It's been just few days but I couldn't be happier! There are few things most negative reviews complain which I have addressed below: 1.) MAC Address is blacked out - Believe that's intentional and Netgear provides the exact instructions on how to retrieve the MAC address. 2.) Activating with Comcast is a pain - This couldn't be farther from the truth. I use Comcast Xfinity and activating it was a breeze. Just go to Comcast.com/activate to use the device without calling customer support. It's self service and is pretty easy to use. In fact if I remember correctly it doesn't require MAC address, you just need to plug in your computer to the modem via a LAN cable (which is included in the packaging). After activating it I couldn't believe it was so quick. I called up customer support just to confirm whether they see my router activated on their end and it showed up in their systems (although after almost an hour after activation) 3.) Slow Wifi speed - i haven't noticed any drop in the wifi download or upload speed. Connecting on 5Ghz gives me a full 100mbs download speed (which is what my Xfinity plan is) and 2.4Ghz gives a reduce speed of around 60mbs. I think that's expected. 4.) Warranty and other quality related issues - Even though it's a refurbished product it appears brand new. It's been just few days since I started using it but I haven't observed any issues that might make me want to contact Netgear support. 5.) Firmware - Netgear's official site for this modem lists the firmware versions that various ISPs support. It supports the latest version for Comcast, but for some reason my modem has not yet updated to the latest firmware. This is an area where I am unsure how to proceed further but again, the current firmware hasn't caused any issues yet. So I am not too concerned. 6.) And then finally, compared to my Xfinity rental modem, which is an Arris, the Netgear modem is sleek looking and has an amazingly fast boot up time. The Arris used to take a good 5-10 mins for the wifi to start working whever it was rebooted. But Netgear takes less 2mins for it to ne up and running.
