cayanna I used double-sided Velcro and hung mine to the wall.  However, mounting holes on the bottom of the unit would be ideal.

Thanks for the feedback,  cayanna 👍

eero is meant to rest on a flat surface, but we know many customers look to mount them to the wall or ceiling. Thanks again for the feedback!

+1 for this feature.   No 'clean' way to mount eeros I have installed in the following locations:

1.  Garage (many devices require wifi/lan in the garage - electric car charger, wifi camera, chamberlain gate gateway bridge)

2. In hall closed where original central wiring for home (including cat5e) was installed - no available shelf.

3. In a kitchen - no counter space available, want to inside of wooden cabinet wall.

Wall or ceiling mount would resolve all three items above.

I've had good luck with these acrylic "postcard holders" and clear Command strips. https://www.amazon.com/dp/B00TQ6B0QM

They're a reasonably close fit for the Eero size, have no metal parts, and don't seem to increase heat retention. You could permanently mount them, of course, but I like the flexibility to and minimal wall damage of the adhesive strips. 

Yes! This or a setup like the google nest cams & smoke alarms that have a super-easy way to mount them
