For some reason my TL WA850RE keeps disconnecting from my main WiFi every other day. I wanted to know if the latest firmware build is 1.0.12 Build 221109 Rel.31477n. I donwloaded the latest version of the firmware from https://www.tp-link.com/us/support/download/tl-wa850re/ but I'm not sure of its version. 

Thanks.
