Hi, currently been using Deco X50-5G as 5g router. And planning to get a few more deco unit specifically just for WiFi coverage (To extend the signal / coverage). Is there any model specifically support that? Like model without ethernet / other component and fully focus on extender. 

If there's no model specifically support this, is there any other options that provide similar effect? Last, if there's no any model as specifically mentioned, any suggestion on budget deco router to go with? The focus just to extend the wifi signal / coverage. Didn't have requirement on the band etc
