WiFiXpert Compatibility Score — eero mesh system
The easiest mesh to live with, but it hides settings, so awkward gadgets sometimes need a workaround rather than a switch.
Plays nicely with almost any Wi-Fi
Eight checks, same for every device. The eight numbers below add up to 84.

What usually goes wrong
A single stubborn gadget won't join, usually because it only understands the older security setting.
Free things to try, in this order
- 1
Turn on the compatibility setting in the eero app while pairing an older gadget.
- 2
Keep one Wi-Fi name for both bands — eero handles the rest.
- 3
Put the main box in the middle of the house, not by the front door.
Before you buy anything
Add one more box before replacing the system.
