I purchased this to resolve the issues I was having with a netgear nighthawk.   The initial 2 months was fantastic, conisitent on both 2.4 and 5 bands - speed consistently 70 - 110 MBps DL.  The last 2 weeks have been a nightmare where it drops to almost nothing, 5 Mpbs, and the ping jumps up and down like crazy.

This makes watching any videos via Apple TV, iPads, etc impossible.

We have 10-15 wireless devices

The wired devices to the router seem to be suffering the same degradation.

The direct speed from the Cable Modem is 100+  Mbps,  no issues there.

I have looked at various settings and cannot find a remedy.  Reboots, factory resets, are no help - Please provide some help
