The controller does not establish a network connection

  • Updated


If you are having trouble connecting the controller to your network, make sure of the following:


Confirm that you are using a 2.4GHz Wi-Fi network, not a 5GHz network.

Plunge products support the 802.11 b/g/n 2.4 GHz Wi-Fi standard. The on board control system cannot be used with 5 GHz and 6 GHz networks. The Wi-Fi standard can vary from router to router.

  • Older dual-band routers will broadcast 2x separate SSID with the 5G one often times having 5G in the name.
  • Modern routers use a single SSID that intelligently steer devices to the appropriate frequency.

Ensure that your various Wi-Fi networks do not share the same name.

It is not typical for you to see more than 1x WiFi network with the same name, but in certain scenarios this could happen. Here are some scenarios and fixes you can try:

2x networks with same name

CAUSE 1: Your router could be broadcasting the same SSID for your 2.4Ghz and 5Ghz bands
FIX 1: Rename the 5G network to include "5G" in the SSID name.
CAUSE 2: You have guest network with the same ssid and password.
FIX 2: To solve just rename your guest network to something else or add guest to the end of it.
CAUSE 3: You have 2 separate routers broadcasting the same SSID.
FIX 3: Turn off or rename the 2nd network. You can usually turn off one of them by setting to Local Area Network (LAN) vs Wireless Area Network (WAN). To do this log into your router admin and disable it. A quick Google or youtube search should get you your specific router instructions.


Same network showing up many times

If you notice that the same network name appears multiple times in the list of available WiFi networks, it's likely that you are using a "mesh router." A mesh router system typically comprises multiple nodes or access points that collectively form an expansive WiFi network. In such systems, nodes within the network function as access points for connecting devices and generally broadcast a single unified SSID (Service Set Identifier).

However, in some older mesh networks, each access point may display the same SSID. If you have an older mesh router that doesn't manage SSID broadcasting intelligently, it might be challenging to connect IoT devices to your network. In such cases, we recommend consulting your router's documentation for further guidance and information.

Popular mesh routers:

  • Google Nest
  • Eero
  • Netgear Orbi
  • Linksys Velop
  • TP-Link Deco


Make sure selected network name or password is no more than 20 characters in length.

If your network name or your password is longer than 20 characters, our controllers will not be able to connect to them. Try shortening the network name (SSID) or create another network or creating a shorter password.
