AX200 (Asus PCE-AX58BT) can't detect 5GHz from ASUS router

[rizalbuluz]

Hi Intel Support,

I’m experiencing an issue with my Asus PCE-AX58BT adapter that uses the Intel AX200 chipset. It doesn't detect the 5GHz SSID from my router, even though all my other devices (phones, laptops, etc.) can see and connect to it without any problem.

Here are the details:

• Wi-Fi Adapter: Asus PCE-AX58BT (Intel AX200)

• Driver version: 23.140.0.3

• Router: ASUS RT-AX1800HP

• Router mode: Access Point (AP) mode

• Operating System: Windows 11 24H2

I’ve tried changing the adapter’s wireless mode to 802.11 a/g, and the 5GHz SSID finally showed up. But when I tried to connect, it said "Unable to connect to the internet."
Switching back to the default mode (802.11 a/b/g) causes the 5GHz SSID to disappear again.

Interestingly, when I use my phone’s 5GHz hotspot, the adapter detects and connects to it perfectly.

I’ve already tried reinstalling drivers, updating to the latest version from Intel, and adjusting various wireless settings, but the issue persists and only occurs with my router’s 5GHz signal.

Would appreciate any help or suggestions to resolve this.

Thanks in advance!

Hello rizalbuluz,

Thank you for posting in Intel Communities.

I understand that you are experiencing an issue with your Asus PCE-AX58BT adapter. Here are a few suggestions that might help resolve the problem:

1. Ensure that the 5GHz band is enabled on your ASUS RT-AX1800HP router and that it is set to broadcast the SSID. You might also want to check if there are any specific settings related to the 5GHz band that could be affecting visibility or connectivity.
2. Sometimes, certain channels on the 5GHz band may not be compatible with all devices. Try changing the channel on your router to see if that helps. Channels 36, 40, 44, and 48 are generally good options to start with.
3. Since you've already tried updating to the latest driver, consider rolling back to a previous version that might have worked better with your setup. Sometimes newer drivers can introduce compatibility issues.
4. Check the power management settings for your Wi-Fi adapter in Device Manager. Ensure that the option to allow the computer to turn off the device to save power is unchecked.
5. Since changing the wireless mode to 802.11 a/g made the SSID visible, try experimenting with other modes or combinations to see if you can achieve stable connectivity.
6. Ensure that your router's firmware is up to date. Manufacturers often release updates to improve performance and compatibility.
7. Consider potential interference from other devices or networks. If possible, test the connection with other devices turned off or in a different location.
8. If none of the above solutions work, it might be helpful to contact Asus for further assistance, as they may have specific insights or updates related to your hardware.

Please let me know if any of these suggestions help or if you need further assistance.

Best regards,

Dear JeanetteC,

Thank you again for your response.

I wanted to follow up and share that I’ve also tested the additional suggestions you mentioned:

• I manually set my router to channel 36 (non-DFS), but unfortunately, the 5GHz SSID still does not appear unless I switch the adapter's mode to 802.11 a/g.

• When the SSID does appear in 802.11 a/g mode, I still get the “Unable to connect to the internet” error upon attempting to connect.

• I also tried using the older Wi-Fi driver provided on ASUS’s support page (intended for the RT-AX1800HP), but the issue remained exactly the same.

• Other devices continue to detect and connect to the router's 5GHz SSID without issues, both on DFS and non-DFS channels.

At this point, I’ve tested all driver versions available, all applicable channel configurations, and power settings, with no success.

Could this be a compatibility issue with the AX200 chipset and certain regional channel settings? If there is a known workaround or if escalation is possible, I’d be grateful for any further guidance.

I’m happy to provide logs or testing reports if needed.

Best regards,
Rizal
