Wireless drops with netgear N750 WNDR4000??

[dludwick]

How can I get my new N750 WNDR4000 to work continuously??
The wireless connection stops working randomly for a minute or two every hour or two.

Just got a new Netgear N750 WNDR4000 but the wireless connection stops working randomly for a minute or two every hour or two. I have 5 wireless devices, all have this problem: Two Dell laptops (1yr, 4yr old), a 3 month old Macbook Pro, iPhone4 and iPhone5.
The WNDR4000 (firmware V1.0.0.88_9.1.77) and set it up 4 days ago (28Nov12) to replace a Linksys WRT54GX2. While the linksys wireless was slower, it was rock solid stable.

I have tried both 2.4GHz and 5GHz modes, and am using the default WPA2-PSK [AES] encryption.

Internet connection is Comcast xfinity cable modem (says ARRIS on back) and live in Chicago. Like I said, the linksys wireless was slower, but it was rock solid stable.

So, How can I get my new N750 WNDR4000 to work continuously??

Thanks,
David
