Hi,

I received a new 1Gbs Fiber internet connection that came with a a WIFI 6 router called Calix GigaSpire BLAST u6.1. 

I want to extend the wifi signal to a tiny home on the property that os ~75feet away.   I do not have electric power connected between the buildings, both are directly connected to the Main meter box.  The tiny home has about 15 wifi devices, 11 x 2.4g IoT devices, about 4 x 5g devices.

I have an RE650 today.  HW V1 and FW 1.0.9 Build 20201112 Rel. 66232.  I have successfully setup this configuration.  Every so often the 2.4g connection between the router and extender goes offline. I dont know why this happens. (any comments here is also appreciated) The 5ghz remain stable.  I am not sure why this happens, as the tether app says 2.4 connection is "great" and the 5g is "good"

When 2.4g is working, i can usually get 20Mb/s speed.  It can run 2K streaming but buffers on 4k.  The 5g usually gets 180-200 Mb/s. and performs very well.

My question is, will i get range or performance benefits by upgrading to the Wifi 6 RE605X?  if so, what could or should i expect?
