Hub5 2.4g cameras and sockets not working

Do you have a VM Hub 5 on defective Software version LG-RDK_11.6.2-2410.1 ? 

If Yes :   the Hub 5 symptoms are either / both : 1) DHCP Server failure, 2) Wi-Fi failure.

The temporary fix is to Press RESET for 60 seconds, then leave the VM Hub Powered ON to complete the factory reset.

Get yourself a better router before Christmas and put hub in modem mode

If you really want to split the SSID and providing your DO NOT have Pods, then see below;

•    Access your Hub by navigating to 192.168.0.1
•    Login with the default login info (on base of Hub) unless you've already updated it.
•    Go to Advanced Settings > Wireless > Security
•    Disable the Smart Optimisation on the wifi bands.
•    Under Wireless Frequency 2.4GHz change the Wifi Network Name (SSID), suggest append _2 to the end.
•    Repeat for the Wireless Frequency 5GHz, suggest append _5 to the end and click on Apply changes
•    Try to avoid spaces and periods in the SSID names as they can cause issues with certain devices.
