Don't know about range with wifi repeater, but there is a separate app called Tals on Play Store to change height up to 100ft. Couldn't get my repeater to connect since they did an upgrade
I'm just telling you about this repeater. I don't have any control over Amazons inventory. Maybe if you took the time to do some research maybe you might find it elsewhere. Just tried to be helpful. So good luck.
I have the Xiaome repeater also. But I find this repeater is easier to connect and works great. https://www.amazon.com/gp/product/B073P2YX64/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1
Activated airplane mode, then wifi. Still keeps asking if I'm in airplane mode. Still no connection. Message reads Internet may not be available, connect to another network. I'm clueless.
Today I tried to use my Samsung tablet to fly the tello. But never would connect. Had no problem connecting with my LG phone. The app on the tablet kept asking if I was in Airplane mode of which I wasn't. What did I miss in making a connection?
