Do I need a modem with this system?

Yes, the Deco XE75 is a router/mesh system. You'll still need a separate modem connected to your ISP. If your ISP provides a modem-router combo, you can either keep using it or replace it with this system depending on your preference.

Is WiFi 6E backwards compatible with older devices?

Yes, completely. WiFi 6E is backwards compatible with WiFi 5, WiFi 6, and even older WiFi standards. All your existing devices will work fine, though only WiFi 6E-capable devices will access the new 6GHz band.

How difficult is the setup process?

Very straightforward. Download the Deco app, plug in the main unit, and follow the on-screen prompts to name your network and create a password. Adding the additional units takes less than 5 minutes each. Most users report the entire setup takes under 15 minutes.

Who Should Buy This?

If your home struggles with dead zones or your WiFi slows down when multiple devices connect simultaneously, this system solves both problems. It's ideal for homes over 3000 sq ft or households with many connected devices (smart TVs, gaming consoles, laptops, phones). The 6GHz band is particularly valuable if you have newer WiFi 6E devices that can take advantage of its dedicated frequency.

Buying Tip

Mesh systems perform best when units are placed in central locations, not hidden in closets or cabinets. If your home has thick walls or multiple floors, position the secondary units strategically for maximum coverage. The 3-pack is usually the sweet spot for medium to large homes; if you need extra coverage, individual units can be added later.
