Check the router’s configuration for anything with the word broadcast in it, or anything like wireless partition/isolation/segmentation, and try toggling those options. If the wired connection works but wireless does not, then the most likely cause is your router blocking certain kinds of network traffic. If you are on the main wireless network, please instead try a wired connection. If your PC is using a wireless connection, make sure that you are on the primary network and not a guest network (guest networks typically block access to local devices on the network). If the network LED is solid green, then the HDHomeRun has an address. If the HDHomeRun is directly connected to the network interface on your computer, the interface should be set to a static IP in the .y range (for example, 169.254.1.9) with a subnet mask of 255.255.0.0 If the router has any access control/allowed devices/MAC filtering function, either the HDHomeRun needs to be on the allowed list, or this function should be disabled. If connected to your main network, check to make sure that your router is powered on and has its DHCP server enabled. If the LED is blinking green, this indicates that the device has a network connection, but has not received an IP address via DHCP. Try a different network cable and port on your switch/router. If the LED is blinking red (HDTC-2US) or solid red (other devices), this indicates that the device does not have a network connection.

For HDTC-2US, the network LED is at the bottom of the network port. For HDTC-2US, the network LED is the furthest left LED.

For HDHR3-US, HDHR3-CC, and HDHR4-2US, the network LED is the furthest left LED. For first/second generation HDHomeRun devices (HDHR-US, HDHR-T1-US, HDHR-EU), the network LED is the leftmost of the ones in the window. Check to make sure that the HDHomeRun has a good network connection, as indicated by the network LED on the device being solid green.
