The ZyXEL WRE6606 may be both a repeater and extender, it can be set to talk with the Breeze on the 5.8GHZ band, and talk with the phone/pad/tablet on either 5.8GHz or 2.4GHz bands. I have flown the Breeze with the WRE6606 on both bands. It is an option for those with phones that only operate on the 2.4GHz to still fly the Breeze.
What was your experience like using the 2.4 band? I tried to use the tello with mine and everything was delayed.
