How to Fix the 6 GHz WiFi Band Not Showing Up on Windows 11: Driver Updates, Regulatory Region Settings, and Intel/AMD Adapter Fixes

WiFi 6E and WiFi 7 routers broadcast on three bands: 2.4 GHz, 5 GHz, and 6 GHz. The 6 GHz band offers the least congestion and — when you’re close to the router — the highest throughput available on any consumer WiFi standard. But Windows 11 laptops and desktops frequently fail to display 6 GHz networks in the available networks list, even when the adapter and router both support it. The cause is almost never hardware failure. It is almost always one of four fixable software or configuration issues: an outdated driver, a misconfigured advanced adapter property, a power plan throttling the radio, or a regulatory region mismatch. This guide covers every fix in order of effort.

Verify Your Hardware Actually Supports 6 GHz

Before troubleshooting, confirm that both your wireless adapter and your router are 6 GHz–capable. Not all WiFi 6 (802.11ax) adapters support 6 GHz — only WiFi 6E and WiFi 7 adapters do. WiFi 6 without the “E” is dual-band (2.4 and 5 GHz only) and cannot see 6 GHz networks no matter what you do.

Common 6 GHz–capable adapters for Windows laptops and desktops:

• Intel Wi-Fi 6E AX210: Tri-band, PCIe M.2 form factor, supports 6 GHz independently of the host CPU.
• Intel Wi-Fi 6E AX211: Tri-band, CNVio2 interface — requires a 12th Gen (Alder Lake) or newer Intel processor to unlock 6 GHz. On older platforms, 6 GHz is hardware-disabled.
• Intel Wi-Fi 7 BE200: Tri-band WiFi 7, CNVio2 or PCIe, requires driver version 23.10.0 or later for 6 GHz support.
• AMD/MediaTek RZ616 (MT7922): Found in AMD Advantage laptops (Lenovo Legion, ASUS ROG, HP Omen), tri-band WiFi 6E. Requires the MediaTek wireless driver, not the generic Windows driver.
• Qualcomm FastConnect 6900 / FastConnect 7800: Found in some Snapdragon-powered laptops, supports 6 GHz with Qualcomm-supplied drivers.

To check your adapter: open Device Manager › Network Adapters and look for the wireless adapter name. Cross-reference it against the list above. If your adapter is not WiFi 6E or WiFi 7, the 6 GHz band is not available on your hardware regardless of any software changes.

Also confirm your router broadcasts on 6 GHz. Log into the router’s admin panel and look for a “6 GHz” or “6E” band option in the wireless settings. The 6 GHz SSID is often separate from your 2.4 and 5 GHz networks. For details on what makes routers and bands different, see our guide on 2.4 GHz vs 5 GHz vs 6 GHz.

Fix 1: Update Your Wi-Fi Adapter Driver

An outdated or manufacturer-bundled driver is the single most common cause of missing 6 GHz networks on Windows 11. Intel’s 6 GHz support was introduced gradually across driver releases, and older drivers actively block the band even on capable hardware.

Minimum driver versions required for 6 GHz support:

• Intel AX210 / AX211 (Wi-Fi 6E): version 22.70.0 or later
• Intel BE200 (Wi-Fi 7): version 23.10.0 or later
• AMD/MediaTek RZ616: the MediaTek MT7921 / MT7922 driver, version 3.x or later from the OEM (not Windows Update)

To update the Intel driver:

1. Download the latest Intel wireless driver from Intel’s Download Center (search for your adapter model). The current package for AX210/AX211 is bundled as the Intel PROSet/Wireless Software installer.
2. Run the installer and select Install. It will uninstall the old driver and install the new one automatically.
3. Restart Windows 11 after installation completes.
4. Verify the new version: open Device Manager, right-click your adapter, select Properties › Driver, and confirm the driver version matches or exceeds the minimums above.

For AMD RZ616 adapters, do not use the driver Windows Update offers — it is often the generic MediaTek driver that lacks full 6 GHz support. Download the driver directly from your laptop manufacturer’s support page (Lenovo Vantage, ASUS MyASUS, HP Support Assistant) or from AMD’s driver page.

Fix 2: Set the Preferred Band in Device Manager

Even with a current driver, the adapter’s advanced properties may have the preferred band set to 5 GHz or to a value that excludes 6 GHz. This does not prevent 6 GHz detection on all adapters, but on Intel AX210, AX211, and BE200 it can suppress 6 GHz networks from appearing in the scan list.

1. Open Device Manager (press Win + X and select it from the menu).
2. Expand Network Adapters and right-click your Intel or AMD wireless adapter.
3. Select Properties, then click the Advanced tab.
4. Scroll the Property list and look for Preferred Band or Band Preference.
5. Set the Value to No Preference (or Auto if that is the available option). This allows the driver to scan all bands including 6 GHz rather than anchoring to one.
6. Also check for a property labeled 802.11ax or 802.11be Mode and confirm it is set to Enabled.
7. Click OK, then disconnect and reconnect to your WiFi network.

On some Intel adapters, the Advanced tab includes a Wireless Mode or HT Mode property. Confirm it is set to include 6 GHz bands (a value like “6GHz/5GHz/2.4GHz” rather than just “5GHz/2.4GHz”).

Fix 3: Change Windows Power Plan to Maximum Performance

Windows 11’s power management can throttle the wireless adapter to reduce battery drain, and on some laptops this throttling disables the 6 GHz radio entirely. Users running the Balanced or Power Saver plan have reported that their 6 GHz networks reappear immediately after switching to Maximum Performance.

1. Open Control Panel › Power Options.
2. Select High Performance or Ultimate Performance (if available).
3. Click Change plan settings › Change advanced power settings.
4. Expand Wireless Adapter Settings › Power Saving Mode.
5. Set the value to Maximum Performance for both On Battery and Plugged In.
6. Click Apply, then OK.

This is particularly effective on AMD RZ616 laptops (Lenovo Legion 5 Pro, ASUS ROG Zephyrus), where the power management profile directly controls which bands the MediaTek radio scans.

Fix 4: Verify Your Regulatory Region Setting

The 6 GHz band is regulated differently in every country. In the US, the FCC has opened the entire 1,200 MHz of 6 GHz spectrum (5.925–7.125 GHz) for indoor and outdoor unlicensed use. Many other countries have opened only a portion of the band or have not yet authorized it at all. Windows 11 uses the regulatory region assigned to the wireless adapter to determine which frequencies it can scan. If the region is set incorrectly — or the OEM shipped the adapter with a region that does not include 6 GHz — the adapter will not scan 6 GHz channels regardless of driver version or band preference settings.

To check the region your adapter is using, open PowerShell as Administrator and run:

netsh wlan show all

Look for the Country or Region line in the output. It should match your actual country. If it shows a different country or “World” mode, the adapter may be restricting 6 GHz.

You cannot directly change the regulatory region in Windows without a driver-level registry edit. For Intel adapters, contact your OEM (Lenovo, Dell, HP, etc.) and request a BIOS or driver update that sets the correct regulatory region for your country. Intel’s official position is that the OEM, not the end user, is responsible for configuring the regulatory domain.

One documented workaround for Intel AX210 users: the adapter detects the 6 GHz band only when the country type is recognized as US. When the adapter reports a “World” or unknown region, 6 GHz is disabled. If your system was purchased in the US but the region is showing as World, a BIOS update from your laptop manufacturer often corrects this.

Fix 5: Intel AX211–Specific: Processor Generation Requirement

The Intel AX211 uses the CNVio2 interface, which means part of the WiFi 6E circuitry lives in the processor chipset rather than entirely on the M.2 card. This architecture has a strict hardware requirement: the host processor must be Intel 12th Generation (Alder Lake) or newer to enable 6 GHz. On an 11th Gen (Tiger Lake) or older system that happens to have an AX211 card installed, the 6 GHz radio is hardware-disabled at the chipset level. No driver update, registry change, or BIOS update will fix this — it is a physical limitation of the CNVio2 interface on pre-12th-Gen platforms.

If you have an AX211 on a pre-12th-Gen Intel platform and need 6 GHz, the only solution is to replace it with an Intel AX210, which uses PCIe rather than CNVio2 and supports 6 GHz on any platform where the M.2 slot provides PCIe lanes. The AX210 is widely available for under $30 and is a straightforward swap in most laptops. See our WiFi upgrade guide for laptops for installation notes.

Fix 6: AMD RZ616–Specific Driver and Registry Fixes

The MediaTek MT7922 (sold as AMD RZ616) has its own set of quirks on Windows 11. The most effective fix for missing 6 GHz on RZ616 systems is a combination of the OEM driver (not the generic Windows Update version) and the correct power plan settings described in Fix 3.

If the OEM driver still does not surface 6 GHz networks, one community-documented workaround involves adding a CountryName registry key to the driver’s parameter registry path and setting it to a country code that permits 6 GHz (such as “US”). This is an advanced step that modifies system registry entries. Only attempt it if you are comfortable editing the registry, and create a registry backup first with File › Export in Registry Editor. The exact registry path varies by driver version and is documented in the MediaTek community forums for your specific OEM model.

Fix 7: Ensure Your Router Uses WPA3 or WPA2/WPA3 Mixed Mode

The 6 GHz band requires WPA3 (or a WPA2/WPA3 mixed mode) security configuration on the router. The 6 GHz band does not support legacy WPA2-only or WEP security modes. If your router’s 6 GHz SSID is configured as WPA2-only, Windows 11 clients will silently fail to display it in the available networks list — not because they cannot see it, but because it does not meet the security requirements to appear. Log into your router’s admin panel, find the 6 GHz band settings, and confirm the security mode is set to WPA3-Personal or WPA2/WPA3 Transition Mode. For a full explanation of WiFi security modes, see our guide on WPA2 vs WPA3.

When Nothing Works: Check for a BIOS Update

Several OEMs (Dell, Lenovo, HP, ASUS) have issued BIOS updates that explicitly fix 6 GHz band availability for specific laptop models. These updates correct the regulatory region burned into the firmware and/or update the CNVio2 initialization code for AX211 adapters. Check your laptop manufacturer’s support page for your exact model number and look for BIOS updates released in the last 12 months that mention WiFi, wireless, or network connectivity. A BIOS update is the correct fix when the regulatory region is set incorrectly at the factory — and it is more reliable than any registry workaround.

If you have confirmed that your adapter supports 6 GHz, your driver meets the minimum version, your router broadcasts WPA3 on 6 GHz, and your regulatory region is correct, but 6 GHz still does not appear, contact your laptop OEM’s support team. The issue may be a known bug in that specific model’s firmware, and OEMs sometimes have targeted fixes that are not published publicly.

Quick Checklist

• Adapter is WiFi 6E or WiFi 7 (AX210, AX211, BE200, RZ616, or similar)
• Intel driver version 22.70.0+ (AX210/AX211) or 23.10.0+ (BE200)
• AX211 users: host CPU is 12th Gen Intel or newer
• Device Manager › Advanced tab: Preferred Band set to No Preference
• Power plan: Wireless Adapter Settings set to Maximum Performance
• Router 6 GHz SSID security: WPA3 or WPA2/WPA3 mixed mode
• Regulatory region: correct country code for your location
• BIOS is up to date for your laptop model

The 6 GHz band is worth the effort — on a clear 320 MHz channel, WiFi 6E and WiFi 7 routers can deliver sustained throughput above 2 Gbps to a compatible client at close range with near-zero interference from neighbors. Once you’ve confirmed your adapter and router both support it, the fixes above resolve the missing 6 GHz issue in the vast majority of Windows 11 cases.
