How to Fix 5 GHz WiFi Not Showing Up on Windows 11: Driver, Adapter, and Band Settings

You open WiFi on Windows 11 and only see your 2.4 GHz network—no 5 GHz option in sight. Your phone and laptop connect to 5 GHz just fine, so the router is definitely broadcasting it. The problem is almost always on the Windows side: the adapter doesn’t support 5 GHz, a driver setting is hiding the band, or the driver itself is outdated or corrupted. Work through these steps in order and you’ll pinpoint the cause in minutes.

Step 1: Confirm Your Adapter Actually Supports 5 GHz

Before changing any settings, verify that your WiFi adapter is physically capable of 5 GHz. Some older laptops and cheap USB adapters are 2.4 GHz only. Open an elevated Command Prompt (search “cmd”, right-click, Run as administrator) and run:

netsh wlan show drivers

Look at the Radio types supported line in the output. If you see only 802.11b 802.11g, your adapter is 2.4 GHz only—no driver update will add 5 GHz capability. You’ll need a USB WiFi adapter or a PCIe card that lists dual-band (802.11a/n/ac or 802.11ax) support.

If you see 802.11a, 802.11ac, or 802.11ax in the list, your hardware supports 5 GHz—continue below.

Step 2: Set the Preferred Band to 5 GHz in Adapter Properties

Windows sometimes defaults to 2.4 GHz even when the adapter supports both bands. You can override this through Device Manager:

1. Press Win + X and click Device Manager.
2. Expand Network adapters and double-click your wireless adapter (often labeled Intel Wi-Fi, Realtek, or Qualcomm).
3. Click the Advanced tab.
4. In the Property list, select Preferred Band.
5. In the Value dropdown, choose Prefer 5.2 GHz band (some drivers label it “Prefer 5 GHz band”).
6. Click OK and wait for the adapter to reconnect.

What if “Preferred Band” isn’t listed?

If the Preferred Band option is missing from the Advanced tab, your current driver doesn’t expose it. Jump to Step 4 to update or reinstall the driver—the option usually reappears after switching to the manufacturer’s driver instead of the generic Windows one.

Step 3: Change the Wireless Mode to Include 5 GHz

In the same Advanced tab, look for a property called Wireless Mode or 802.11 mode. If it is set to 802.11g only or 802.11b/g only, Windows is locked to 2.4 GHz frequencies. Change the value to 802.11a/b/g/n/ac (or the highest mode your adapter lists). Click OK, let the adapter reconnect, then check WiFi again for 5 GHz networks.

A related setting to check is 802.11n mode—make sure it is set to Enabled, not Disabled.

Step 4: Update or Roll Back Your WiFi Driver

A stale or corrupted driver is the most common reason 5 GHz networks vanish. Windows Update often installs a generic Microsoft driver that lacks advanced band controls.

Update via Device Manager

1. In Device Manager, right-click your wireless adapter and choose Update driver.
2. Select Search automatically for drivers. If Windows finds a newer version, install it and restart.

Download directly from the manufacturer

Device Manager doesn’t always find the latest driver. For Intel adapters, visit Intel’s Download Center and search your adapter model (e.g., Intel Wi-Fi 6E AX211). For Realtek and Qualcomm adapters, check your laptop manufacturer’s support page—Dell, HP, Lenovo, and ASUS all publish driver packages tailored to their hardware. Download the latest package, run the installer, and restart.

Roll back if 5 GHz disappeared after a Windows Update

If 5 GHz was working before a recent update, the new driver may be the culprit. In Device Manager, go to your adapter’s Properties → Driver tab and click Roll Back Driver. If that option is greyed out, uninstall the current driver (check “Delete the driver software for this device”), restart, then install the previous version from the manufacturer site.

Step 5: Disable and Re-enable the Adapter

A quick toggle can resolve transient glitches that prevent band detection without requiring any driver changes:

1. In Device Manager, right-click your wireless adapter and select Disable device.
2. Wait 10 seconds, then right-click again and choose Enable device.

Alternatively, open Settings → Network & Internet → Advanced network settings, click your WiFi adapter, and use the Disable / Enable buttons there.

Step 6: Verify Your Router Is Broadcasting 5 GHz

Before concluding the problem is entirely on the Windows side, double-check the router. Log into your router admin panel (typically 192.168.1.1 or 192.168.0.1) and confirm that the 5 GHz radio is enabled and that its SSID is being broadcast (not hidden). Some routers ship with 5 GHz disabled or set to a different SSID. Also check that the 5 GHz channel is set to a value your region allows—channels 36–48 and 149–165 are available in most countries.

If you use band steering (a single combined SSID for both bands), try temporarily splitting the networks into separate SSIDs. Some Windows drivers struggle to latch onto 5 GHz when band steering is active. Once you confirm the adapter can see 5 GHz under a dedicated SSID, you can re-enable band steering. See our guide on how to enable band steering for per-brand instructions.

Quick Fix Checklist

• Run netsh wlan show drivers and confirm 802.11a/ac/ax appears under Radio types
• Set Preferred Band to Prefer 5.2 GHz in Device Manager → Advanced tab
• Change Wireless Mode to include 802.11a/n/ac
• Install the latest driver from Intel, Realtek, or your laptop OEM’s support page
• Disable and re-enable the adapter to clear transient glitches
• Log into your router and confirm 5 GHz radio is enabled and broadcasting

Once you’re connected on 5 GHz, run a WiFi speed test to confirm you’re getting the faster speeds that band delivers. If speeds still disappoint after fixing the band issue, check our full guide to why WiFi is slow for the next layer of fixes.
