A secure Wi-Fi network is needed to connect the app to the controller. In addition, a strong Wi-Fi signal is also recommended. You may need to move your router closer to the U by Moen device in order to improve the Wi-Fi connection.

The following list of routers have been tested by Moen and are compatible with the U by Moen:

Netgear: WNDR-4500; R6100; WNDR3700v4
Cisco: EA3500; EA6300; EA9200
Linksys: WRT1900AC v2
D-link: DIR-880L; DIR-636l
ASUS: RT-N66U; RT-AC87U; RT-AC3200
TP-Link: TL-WR1043ND; AC1750v2
TRENDnet: TEW-812DRU
Ruckus: Zoneflex R500
Belkin: F9K1103Vi

In some instances, resetting the router or adding a Wi-Fi repeater or extender can help in connecting the app to the controller.
