WBE 665S Indoor Mode
Overcoming Outdoor 6GHz Restrictions The WBE 665S is an outdoor tri-radio access point. However, strict regulations in many regions (like the EU) prohibit 6GHz usage outdoors without specific coordination (AFC). The Indoor Mode Solution For users who wish to use this powerful outdoor AP in large indoor spaces like…

Neighbor Scan Live Tool
Diagnostic Visibility The Neighbor Scan is a live tool that lists devices broadcasting beacon frames or probe responses nearby. It scans all radio bands and channels supported by the hardware, though it is dependent on the specific AP model (e.g., a Wi-Fi 6 AP cannot scan 6GHz). Key Features * Retention: Scanned entries…

Authentication Certificate Renewal
Addressing Certificate Expiration Cloud-managed APs use a specific 802.1X certificate for WPA Enterprise authentication. Many of these certificates were set to expire in February 2026, which would cause authentication failures for clients. Proactive Provisioning To prevent disruption, NCC proactively provisions new…

How to Implement Band Steering in Standalone Mode for Zyxel APs?
Band steering is a feature designed to guide dual-band client devices towards the faster and less congested 5 GHz Wi-Fi band. While native Band Select functionality is not supported in Standalone mode for Zyxel Access Points, you can implement alternative strategies to encourage clients to prefer the 5 GHz band. Configure…

Why is my access point unable to update its system time?
If your access point (AP) cannot synchronize its system time with an NTP server, verify the following requirements: 1. Allow NTP traffic through the firewall UDP port 123 must be open. NTP domains must be reachable: *.pool.ntp.org time.google.com 2. Importance of UDP port 123 NTP relies entirely on UDP port 123. If this…

Why are some WBE660S devices connecting at only 1Gbps or 5Gbps instead of 10Gbps?
This behavior is typically related to physical layer issues such as cable quality, cable length, termination quality, or port negotiation inconsistencies. To isolate the cause, test with certified Cat6a cables, swap APs between ports that successfully negotiate 10Gbps, and verify that both ends of the cable are properly…
