6GHz WiFi not available for SCR 50AXE

Hi Zyxel Support,

Model: SCR 50AXE

Firmware: V1.20(ACGN.0)

I am currently live in Vietnam and the device comes from a local distributor. Can you advise how to enable 6GHz on the SCR 50AXE? I've checked the SSID setting and Radio setting in Nebula but it is not available (no channel available when changing the Channel to Manual).

FYI, Vietnam's Ministry of Information and Communications (MIC) is enabling 6 GHz WiFi (WiFi 6E/7) with Circular 01/2025/TT-BKHCN (amended from Circular 02/2024/TT-BTTTT), effective May 15, 2025.

To test it further, I have set the ORG country, Radio country to Malaysia but 6GHz is also not available.

Thank you!

Hi @vantc,

According to the screenshot you provided, please note that for SCR 50AXE, the 6 GHz band only supports 160 MHz channel width.

If the issue still persists after the adjustment, please enable Zyxel Support Access and provide us with your org and site name so we can help check the configuration.

Hi @vantc,

Thank you for providing the information!

To help us clarify the behavior, could you please confirm one more detail on your side?

Are you able to see the SSID being broadcast on the 6 GHz band from the SCR 50AXE after setting the 6 GHz band to a 160 MHz channel width?

Hi Tina,

I am currently using the Intel BE200. After connected, it is still on 5GHz.

On the SCR50AXE, I can see channel 21 on 6GHz, but the status is OFF.

Hi @vantc,

After verification, we would like to clarify the behavior you are seeing. The radio settings page in Nebula is shared between APs and SCR 50AXE devices, but the supported country list corresponds to AP regulatory domains, not the SCR 50AXE list.

Since Malaysia is not included in the SCR 50AXE country list, the 6 GHz Channel ID options do not appear when Malaysia is selected. We acknowledge the mismatch with the supported 6 GHz country list for SCR 50AXE and will update this information correctly in NCC in the future.

As a workaround, if you change the country setting to another supported region (for example, Taiwan), the 6 GHz channel selection options will appear normally.

We apologize for any confusion this may have caused.

Regarding your observation that the local GUI shows the 6 GHz radio status as OFF: this is because the radio will only activate when the country setting corresponds to a regulatory domain that supports 6 GHz on SCR devices. Only then will Nebula push the correct configuration to the device and fully enable the feature.

Therefore, we recommend setting the country to a supported region and testing again to confirm that your clients can access the 6 GHz band.

Hi Tina,

Thank you very much for the information. Finally, I can see 6GHz radio works on Nebula & Router local management IP. Unfortunately, WiFi status on my PC shows 5GHz only (Intel BE200, Windows 11).

Can you advise? Thank you.

When scanning the SSID, I can see collocated AP on 6GHz, but Windows 11 only connects in 5GHz.

(There are 2 colocated AP since I created another AP, only broadcasting it 6GHz, but also not visible).
