Any idea how to downgrade back to the 1.01 firmware that was not "beta", wifi keeps cutting out every 15 minutes (exactly) when connecting under firmware 1.10 (many devices)

does the emergency firmware recovery method also work for this extender as it does on others (like the older 1665)?

Yes if Recovery mode is supported, use that mode to apply v1.01.
I would contact D-Link support and let them know what your having problems with.
