The "W5" model includes dual-band 802.11ac. However, early firmware limited the 5GHz band to 433Mbps. Updated firmware unlocks full 867Mbps or even 1.2Gbps speeds, better beamforming, and MU-MIMO support.
Remote Code Execution (RCE) flaws in the web management interface. Cross-Site Scripting (XSS) vulnerabilities.
