Keeping your router’s firmware up to date is essential for security, stability, and speed. Movistar (Telefónica) often pushes automatic updates, but sometimes you need to check or force an update manually—especially if you are experiencing Wi-Fi drops, slow performance, or have disabled the TR-069 remote management protocol.

If you still experience issues after updating, consider buying your own router (Movistar allows bridge mode on most fiber models) for better performance and more frequent firmware support. Updated: March 2025 – Based on Movistar Spain fiber routers (HGU models). For ADSL or Latin American Movistar variants, steps are similar but menus may differ slightly.
