How can I connect a 2.4 GHz camera base via ethernet? My network shows my wifi is running at 5 GHz.
If you meant 2.4 WiFi, and you are using a Comcast supplied gateway device,
the two WiFi bands have recently been combined into one with the Comcast gateway devices. Some devices get confused and don't know how to see / talk to combined bands.
If you are not using any Xfi Pods, you can try separating the 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;
Camera base has been connected with ethernet cable and doesn't recognize/connect. Xfinity support helped me to rename 2.4 and 5 MGz separately, I thought it would help camera base connect if my wifi was set to 2.4 MHz. No dice. Camera support walked me thru connections as well... no dice. Might be camera base itself... oh well. They did suggest new base to be sent... we'll see.
An ethernet connection does not use Wi-Fi and does not use either 2.4 GHz or 5 GHz.
Try using another ethernet cable. Perhaps the one you are using is not working.
In short, when you connect your camera to your router via ethernet, it should automatically connect and appear in your network. You may have to determine what IP address the camera has in order to connect to it. Be advised that the IP address of the camera can change each time you reboot the modem/router, unless you assign a static IP address to it.
