Q: Is this router compatible with fiber internet? A: No, this router only has a 100Mbps WAN port. While you can connect it to a Fiber ONT (modem), it will bottleneck speeds above 100Mbps. It is best suited for ADSL modems or cable internet plans under 100Mbps.
Q: Can I use this as a Wi-Fi extender? A: Yes. In the router settings, look for "Operation Mode" and switch it to Repeater or WISP mode to extend the signal of your main router. Warning: Do NOT download firmware from random forum
Q: Where can I find the firmware file if the manufacturer website is down? A: If the official site is unavailable, search for the specific chipset firmware (usually Realtek or MediaTek) or contact the seller directly. Avoid downloading files from unverified third-party file-hosting sites.
Important Warning: Do not update the firmware over a wireless connection. Interruptions during the update process can "brick" the router, rendering it unusable. Always use a wired Ethernet connection.
