Changing the IP address of your hub
From the Hub Manager go to Advanced settings then My Network then IPv4 configuration
You can view and make changes to your Hub's IP and DHCP settings (if you need to revert to the default settings, there's a Reset to default button on the top right of the page).
IP address
The default IP address is 192.168.1.254 but you can change that here.
DHCP server
You can switch the Hub's DHCP server on and off.
When enabled, the Hub will lease IP addresses automatically when your devices connect.
If you want to use your Hub as a modem only and connect another router to use as an access point, then you might want to disable this.
