"Discovering..." appears in Shure Update Utility when your devices and your computer have different network settings. For example, your computer has an IP address of 192.168.1.2, but your devices have a self-assigned address beginning with 169.254.xxx.xxx.
Set your devices and your computer to Automatic or DHCP mode and then reboot the Shure equipment. You don’t need a DHCP server on the network, but it’s fine if one is present. See
IP Addresses and Subnet Masks for more details on network settings.
If your devices don’t appear at all, see
Shure Update Utility: Devices Don't Display for troubleshooting steps.
Less Common Causes of "Discovering...":
- Firewall is misconfigured - Ensure the firewall is allowing SUU to send and receive traffic. Step-by-step configuration directions are in Shure Update Utility: Devices Don't Display.
- ANI or MXA310 with Split Subnets - ANI4IN, ANI4OUT, ANI22, and MXA310 don’t support splitting the Shure Control and Network Audio (Dante) traffic into different networks. Configure these devices with both IP addresses in the same subnet as your computer.
- Disqualified Switch - Ensure your switch is not on our list of Disqualified Network Switches for Shure Dante Devices, and follow our guide to Configuring a Network Switch for Shure Devices and Dante/AES67.
- Connecting via Wi-Fi - We do not recommend updating the firmware on Shure devices via Wi-Fi, as this increases the risk of a failed firmware update. Always update firmware via a wired Ethernet connection.
- Bad Ethernet Cable - Occasionally, the cable itself is bad and needs to be replaced. This can cause unexpected or intermittent behavior.
- Network Address Translation (NAT) - Some networks with Network Address Translation (NAT) pass multicast discovery messages between subnets. We don’t support this configuration. Connect directly to the device you wish to update using a good Ethernet cable, using a power over Ethernet injector if required.
