hi, got the RE205 setup as an access point and i want it to be a mesh for other devices to seamlessly connect from it to the main wifi router, i dont see any options to do that, when choosing wifi i see the main wifi connection and the extender both seperately only the extender has no password to join it, any help here would be awesome, i dont really want to go back to using it as an extension since it kept dropping out even when close enough for a good connection to the main wifi router

the router im using is the TP-Link Archer AC2100 VR2100v v1 running the latest firmware 1.13.0 0.9.1 v009e.0 Build 220623 Rel.61658n
