Ib-wrb304n Firmware Update Guide

For 99% of users: . A failed update turns a working (if basic) router into a paperweight. If you need modern features or security, buy a $20-30 router from a known brand (TP-Link, Xiaomi, Asus) with automatic updates. Safe alternative: Disable WPS, change default admin password, and use the router as an access point behind a main firewall. No firmware update required.
