Do I need a mesh system or access points?

A mesh Wi-Fi system spreads seamless coverage across a larger home with several units that act as one network. Access points extend a wired network with strong Wi-Fi in specific spots, which suits bigger or business setups. Both fix dead zones better than a single router.

Will this work with my existing router?

Mesh systems usually replace your router's Wi-Fi, while access points connect to your existing network by cable. Check whether you want to replace or extend, and that the units support the Wi-Fi standard you need.

How do I get the best coverage?

Place units so their coverage overlaps a little, and wire them back to the network where you can for the most stable speeds. Wi-Fi 6 or Wi-Fi 7 hardware gives the best performance for modern devices.
