Frequently Asked Questions - COM-8400 Steren
How do I reset the Steren COM-8400 to factory defaults?
To reset the device to factory defaults, locate the Reset button on the side or back of the repeater. Use a paperclip to press and hold it for about 10 seconds until the power LED flashes. Release the button and wait for the device to restart. This will restore all settings to out-of-box defaults.
How can I set up the repeater using WPS?
Press the WPS button on your router first, then within 2 minutes press the WPS button on the COM-8400. The WPS LED will blink while the connection is established. Once solid, the repeater is paired. You may need to reconnect your devices to the repeater's network.
What should I do if the Wi-Fi signal from the repeater is weak?
Place the repeater halfway between your router and the dead zone, ideally within range of the router's Wi-Fi. Avoid obstructions like walls or metal objects. Also, try changing the channel on your router to reduce interference. Ensure the repeater is updated and operating in a clear 2.4 GHz band.
Can the COM-8400 work with any router?
The COM-8400 is compatible with any standard router that supports IEEE 802.11 b/g/n on the 2.4 GHz band. It uses the WPS or web-based setup, so it works with most brands. However, it does not support 5 GHz networks, so your router must broadcast a 2.4 GHz signal.
How do I change the network name (SSID) of the repeater?
Connect your computer to the repeater's network, open a web browser and enter 192.168.0.1 (or the address from the manual). Log in with the default credentials (usually 'admin'/'admin'), navigate to the Wireless Settings section, and modify the SSID field. Save and reboot.
Is the device compatible with 5 GHz Wi-Fi?
No, the Steren COM-8400 operates only on the 2.4 GHz frequency band. It cannot detect or extend 5 GHz networks. If you have a dual-band router, ensure the 2.4 GHz SSID is enabled and use separate names for each band.
How do I update the firmware?
Visit the official {Steren support website} and download the latest firmware for the COM-8400. Unzip the file, log into the repeater's web interface, go to System Tools > Firmware Upgrade, select the file, and start the upgrade. Do not power off during the process.
What is the maximum coverage range of the repeater?
The actual coverage depends on your environment, but the COM-8400 can extend your Wi-Fi signal up to approximately 300 meters in open areas. Indoors with walls, the range is typically 50-100 meters. Position the repeater for optimal results.
Can I connect an Ethernet device to the repeater?
Yes, the COM-8400 has one Ethernet port that can be used to connect wired devices like a smart TV, gaming console, or computer. Once the repeater is connected to your Wi-Fi network, simply plug the device into the port and it will receive network access.
How do I secure my network with this repeater?
Use the repeater's web interface to set WPA2 encryption, which is the most secure option. Create a strong password with at least 8 characters, including letters, numbers, and symbols. Disable WPS if you are not using it, and regularly check for unauthorized connections.
