Summary - R7800 router crashes when Macbook Air joins the network
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Critical
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
 - Device problem occurs on: Netgear R7800 Router, Macbook Air 11" Mid-2013, Macbook Air 13" 2017
 - Software versions of OpenWrt/LEDE release: LuCI branch git-20.201.65700-7edd635
 - Steps to reproduce: I join the device to the network with either ethernet or wifi and the router would shortly crash.  I simply reboot the router and connect the macbook via ethernet or wifi after the router is up.  I would then run a speedtest (it's not related to any particular activity, but I just use speedtest.net as a control)
 - Attempts at trying to remedy issue: I tried disabling IPv6 on the router and macbooks.  I signed out of icloud.  I updated Macbooks to MacOS Catalina.  I tried flashing router to latest stable release 19.07.3.  The network only dies when these Macbook Airs connect to the network, all other devices don't have any issues.  Prior to this router, I had a Netgear AC1900 (R7000) running DD-WRT which never had this issue.
