- Only one wired port will be active, so you can only connect one device
- No routing services will be provided, so only one device can be connected to your Gateway
- No security features will be available to protect your devices
- It will essentially act like a standard modem
In most cases, you'll need to have your own separate router to provide services to your multiple internet-capable devices.
Check
To check your connection, make sure your computer has an Ethernet connection to your Wireless Gateway.
If your connection isn't that strong, place your xFi Gateway at least three feet from the ground and avoid cramped space.
You'll want to place it in a central location without walls or furniture blocking the signal.
Before making changes to the Wireless Gateway, ensure you're connected to it directly, not to any other router you may have.
Make sure you're not connected to the Wi-Fi connection provided by your Wireless Gateway, as this can prevent changes from being made.
