Whether you’re setting up an indoor or outdoor unit, this guide will help ensure proper SIM card installation, initial network connection, and access to the device’s configuration panel. Use this as a starting point to configure internet settings, Wi-Fi, firmware updates, and more, directly from the built-in web interface.

Design and bundling

The FWA505 comes with an internet cable and power supply, while the external antenna and SIM card are not included.

Setting up the device

First, please follow the steps outlined in the quick start guide and carry out each step as shown.

• Make sure the Zyxel Device is turned off.
• On the bottom of the Zyxel Device, open the micro SIM card slot cover.
• Insert the micro SIM into the SIM card slot (If the SIM card's PIN code is enabled, either enter it later in the device’s web interface or disable PIN verification beforehand).

• Put the cover back in place.

  Note: If you are using a nano-SIM card, insert it securely into the micro-SIM card slot to avoid possible damage to the device.

The Zyxel FWA505 is a 5G NR router that supports wireless and wired connections. To log in to the standalone management interface, use the access credentials printed on the back of the device. 
 

WIFI (SSID) connection	Using WPS	Erhernet Cable

To connect to the FWA505, use WPS, select the WiFi SSID manually, or connect an Ethernet cable. 

To access the router, open a browser and navigate to 192.168.1.1 (this IP is also listed on the device's sticker or can be found through your computer's network settings).

On the first step, the system will ask you to change the default password; this action is mandatory.  Change the password and log in to the device's web GUI with the new password.

Next, follow the prompts and use the wizard to perform basic device settings, such as setting the correct time search, renaming the SSID, and changing the Wi-Fi password.

That’s it - the basic setup is complete, and you can now access the internet via Wi-Fi or a wired connection.
