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…

What happens to my data when Cloud-Saving Mode is activated on Nebula?
Once Cloud-Saving Mode is activated, all monitoring data will not be collected and stored on the backend platform. Therefore, Zyxel support cannot provide this information. Previous records cannot be restored even if the organization is upgraded to Nebula Professional (Pro or Plus) as it won't exist on the backend.…
-
How can I record AP performance logs during standalone testing?
To capture wireless performance data during standalone testing, run the following commands on the AP to monitor signal quality, station information, and RF interference: Router> show wireless-hal station info Router> show wireless-hal statistic These commands help you observe real-time client signal strength and radio…
-
How do I enable MLO functionality?
MLO (Multi-Link Operation) is automatically enabled when the access point is running in 802.11be mode on firmware V7.20 or later, so no manual activation is required.
-
Is WPA3-Enterprise with AES-192 available on Zyxel Access Points?
Zyxel Access Points (APs) currently support WPA3-Enterprise with AES-128 encryption. However, some environments, especially those utilizing Windows Server-based Network Policy Servers (NPS) for RADIUS authentication, may specifically require WPA3-Enterprise with AES-192 encryption, leading to potential compatibility…
-
What license is required for the Access Points to come back online?
Even if the licenses for your Access Points have expired, the devices will remain online and continue to operate. Basic cloud-based management in Nebula — including device onboarding, monitoring, and basic configuration — is free and does not require any license. Licenses are only needed for advanced features. Available…

Why can’t I fix the 5 GHz transmit power at 30 dBm?
The AP follows both regulatory limits and hardware design constraints, and in your region the maximum allowed fixed transmit power for the 5 GHz band cannot exceed the value currently shown in the interface.
-
I enabled 5 GHz but cannot connect. What should I try?
If your device cannot connect to the 5 GHz network, try the following: Update the client device driver to ensure compatibility with 5 GHz WiFi. Confirm the device is receiving a signal stronger than –65 dBm, as weak signals can prevent connection. Disable “Avoid 5G DFS channel” so the AP can use a wider range of channels,…
-
Are there any roaming settings I can adjust?
Nebula APs support several roaming-related options: 802.11r – Speeds up roaming (recommended for WPA2-Enterprise). 802.11k/v – Helps clients discover better APs faster. Smart Steering – Guides clients to the best AP/band. Band Select – Pushes dual-band devices to 5 GHz/6 GHz. Output Power – Lower power can reduce sticky…

Troubleshooting WiFi Performance Issues Despite Full Signal Bars
It's common to see full WiFi signal bars on your device but still experience slow speeds, high latency, or packet loss. While full signal bars generally indicate strong signal strength (RSSI), they don't always reflect other critical factors like interference, channel congestion, or actual data throughput that can…

Why do I get an error when applying "Force Overwrite VLAN Setting" on the USG FLEX 100H
Issue: When enabling Force Overwrite VLAN Setting and entering the Management VLAN in the USG FLEX 100H GUI (Wireless Access Point settings), an error appears after clicking Apply, even though the same configuration works normally through the CLI. Explanation: This behavior is a known issue in uOS firmware version 1.32.…

Why my access point show “Limited” status on the AP controller?
If the WAX650S access points appear as “limited” when managed by a AP controller, the issue is typically caused by a configuration mismatch. Possible reason A radio country code mismatch was configured between the two radios, ex: Radio1 profile use for 2.4Ghz band, Radio2 profile use for 5Ghz band. Radio1 set to Thailand…
