@PeteCozens This page gives you a basic enough idea: Get to know Deco APP 3.0 You can also check reviews on YouTube and/or other sites

@DiStefano You can't. Workaround is to restart the router & hoping for a better channel

@Sahil_D The differences are only in speed, signal & gigabit ports. Looks like you've already done enough research to choose one of them

@Shrops Download center shows all hardware versions. Maybe V2 is sold out, and some V1 are left?

@kikoman1972 If the Decos are M4 (V4)/ M5/M9 plus/ X50/X55 they have the feature of manually selecting signal source. For any other models, set them as far from one another as you can

@andrenb It depends on the hardware & the manufacturer. If the hardware is capable of handling WPA3, it'll receive support for it via firmware update. All the older Eero pro routers got WPA3 support...
