XR700 disconnects continuously

Hi all,

I recently purchased a brand new XR700 and it's been a nightmare so far. Setup just fine, auto patched to the latest firmware no problem  As soon as I started using it, however, I began to get constant disconnects on both my wired and wireless devices. Dug around on these forums and tried all the steps listed below and am still getting constant disconnects. Posting here hoping maybe someone has found a solution or maybe heard if Netgear is doing anything to fix the problem? At this point, the router is just an expensive paperweight =(

Steps taken so far with the latest firmware: 

• disabled ping assist - still disconnects
•  lowered MTU size - still disconnects
• Turned off beamforming etc - still disconnects
• turned off/ lowered anti-buffer bloat - still disconnects
• turned off DHCP and assigned static IP's to my devices - still disconnects

Downgraded firmware and did a factory reset - still disconnects

If I unplug the XR700 from my modem and plug my trusty old D-Link in all of the problems go away and all of my devices stay connected with no drops.

Any other things I could try before I give up on this router?
