@0ID There isn't much difference between X50 & X55. Most of the times, they even receive updates at the same time. The setup cannot be done without the Deco app though

@David-TP Any update on the stable release?

@FaisalSaleem Deco routers in Bangladesh have been customized to work in Band 4. I don't think X20 V3 is available here yet

@FaisalSaleem Contact the local distributor of tp-link for support

@POLYCoach Yes you can access & control them from the same account in Deco app

@Shigeru_Lloyd If the hardware version is V4, they support connection preference, which can be used to connect third Deco to second Deco. If the hardware version is V2, wait for the 1.7.0 stable...
