Top 7 Fixes for Windows 11 Not Detecting 5GHz Wi-Fi

You got a new router, set up the 5GHz band, and all your other devices connected to it – but the network isn’t even showing up on your Windows 11 laptop; only the 2.4GHz network is visible. This is a specific issue, which is why you might be searching for solutions when Windows 11 is not detecting 5GHz Wi-Fi. The good news is that the cause is usually related to software settings or driver issues – hardware failure is very rare. In this troubleshooting guide, we will cover the seven most effective settings and fixes to resolve this problem step-by-step.

First, understand this – what is the difference between 5GHz and 2.4GHz?

Before you start troubleshooting, it is important to understand the actual difference between the two bands.

2.4GHz:

• Greater range – the signal penetrates walls.
• Lower speed – maximum theoretical 600 Mbps (on Wi-Fi 4).
• Higher interference – Bluetooth, microwaves, and neighboring networks all operate on this band.
• Default on older and budget routers in India.

5GHz:

• Limited range – walls block the signal.
• Very high speed – up to 3.5 Gbps on Wi-Fi 5, and even higher on Wi-Fi 6.
• Low interference – a cleaner connection.
• Best for gaming, video streaming, and working from home (WFH).

If your PC and router are in the same room and support 5GHz, connecting via 5GHz offers better performance. That is why it is important to fix the issue where Windows 11 is unable to detect the 5GHz Wi-Fi network.

First, confirm: Does your PC support 5GHz?

This is the very first step. If the PC’s Wi-Fi adapter itself doesn’t support 5GHz, then adjusting other settings won’t help.

Method – Via Device Manager:

1. Press Win + X → Open Device Manager.
2. Expand “Network adapters”.
3. Note down the name of your Wi-Fi adapter – such as “Intel Wi-Fi 6 AX201” or “Realtek RTL8821CE”.
4. Right-click on it → Properties → Advanced tab.
5. Look for the “Band” or “Wireless Mode” property here.
6. If you see “5GHz” or “802.11a/n/ac/ax” in the values, the adapter supports 5GHz.

Method – Via Command Prompt:

1. Open Cmd (Admin).
2. Type this command:

netsh wlan show drivers

3. Check “Radio types supported” – if 802.11a, 802.11n (5GHz), 802.11ac, or 802.11ax is listed, then 5GHz is supported.

If only 802.11b/g/n appears, then the adapter supports only 2.4GHz, and 5GHz will never show up.

If the adapter does not support 5GHz:

• Get a dual-band external USB Wi-Fi adapter.
• TP-Link Archer T2U Plus (5GHz support) – Available on Amazon India for the equivalent of approximately $12–15.

Setting #1 – Change the Wi-Fi Adapter’s Band Preference

This is the most common fix that often immediately resolves the issue where Windows 11 fails to detect 5GHz Wi-Fi networks.

Windows has a “Preferred Band” setting for the Wi-Fi adapter that determines which band the adapter searches for networks on first. If it is set to 2.4GHz, 5GHz networks may not appear at all or may show up very infrequently.

Steps:

1. Win + X → Device Manager.
2. Network adapters → Your Wi-Fi adapter → right-click → Properties.
3. Go to the Advanced tab.
4. Look for this in the Properties list:
   • “Preferred Band” or
   • “Band Preference” or
   • “Wireless Mode”
5. Set the value to “Prefer 5GHz band” or “5GHz”.
6. Click OK and refresh the Wi-Fi list.

If the “Preferred Band” option is not visible:

• Set both “802.11n Channel Width for 2.4GHz” and “802.11n Channel Width for 5GHz” to Auto.
• Set “Wireless Mode” to IEEE 802.11a/b/g/n or Auto.

Setting #2 – Update the Wi-Fi Adapter Driver

An outdated or incompatible driver may fail to properly detect the 5GHz band. This is a very common cause.

Method A – Via Device Manager:

1. Device Manager → Network adapters → Wi-Fi adapter.
2. Right-click → “Update driver” → “Search automatically”.

Method B – From the manufacturer’s website (more reliable):

For Intel Wi-Fi adapters:
🔗 intel.com/content/www/us/en/support/detect.html
Intel’s “Driver & Support Assistant” tool automatically detects which driver is needed.

For Realtek Wi-Fi adapters:
🔗 realtek.com/en/downloads

Use the laptop manufacturer’s website for Qualcomm Atheros:

• HP: support.hp.com
• Dell: dell.com/support
• Lenovo: support.lenovo.com

Restart your PC after installing the driver. Then check the Wi-Fi list – the 5GHz network should be visible.

Setting #3 – Is the 5GHz band enabled on the router?

Even if everything is fine on the Windows side, if the router itself has stopped broadcasting the 5GHz band, there is nothing Windows can do.

Check the router’s admin panel:

1. Type 192.168.1.1, 192.168.0.1, or 192.168.29.1 (for Jio) into your browser.
2. Log in using the username and password (default: admin/admin, or check the label on the back of the router).
3. Open the Wireless Settings or Wi-Fi Settings section.
4. Locate the 5GHz tab or section.
5. Check that the “Enable” toggle is turned ON.
6. Verify that the SSID (network name) is set.
7. Ensure the security is set to WPA2 or WPA3.

Also check the router channel setting:

In India, certain channels on the 5GHz band are regulated. Check the Wi-Fi → 5GHz → Channel settings in the router admin panel.

• Channels 36, 40, 44, 48 – Allowed and most compatible in India.
• Channels 149, 153, 157, 161, 165 – Allowed in India.
• DFS Channels (52–144) – Some devices do not detect these.

If the router is on a DFS channel, manually change the channel and set it to 36 or 40.

Setting #4 – Check Windows Region Settings

This is a reason very few people are aware of. The Windows region setting tells the Wi-Fi adapter which channels and frequencies to use. An incorrect region setting prevents the 5GHz band from working properly.

How to check the Region/Country setting:

1. Win + X → Device Manager.
2. Network adapters → Wi-Fi adapter → Properties → Advanced tab.
3. Look for “Country Region,” “Country Code,” or “Regulatory Domain” in the property list.
4. Set it to India, 0x30 (India), or Asia.
5. If it is set to “0x10” (US) or any other region, change it to India.

Check the Windows region settings as well:

1. Settings → Time & language → Language & region.
2. Select India under Country or region.
3. Restart the PC.

This setting affects the wireless regulatory domain, which directly controls 5GHz channel availability.

Setting #5 – Disable/Enable the Wi-Fi adapter and perform a network reset

Sometimes, the adapter state becomes corrupted, preventing it from scanning the 5GHz band. A simple reset resolves this.

Wi-Fi Adapter Reset:

1. Click on the Wi-Fi icon in the system tray.
2. Turn off the Wi-Fi toggle.
3. Wait for 15–20 seconds.
4. Turn on the Wi-Fi toggle.
5. Refresh the network list.

Reset from Device Manager:

1. Device Manager → Network adapters → Wi-Fi adapter.
2. Right-click → “Disable device” → Yes.
3. Wait 10 seconds.
4. Right-click → “Enable device”.

Network Stack Reset (from Command Prompt):

1. Open Cmd (Admin).
2. Run these commands:

netsh winsock reset
netsh int ip reset
ipconfig /flushdns

3. Restart the PC.

After this, check the Wi-Fi list – the 5GHz network should be visible.

Setting #6 – Unblock 5GHz via Power Management

Windows Power Management settings prefer keeping the Wi-Fi adapter on the 2.4GHz band because 5GHz consumes more power. You need to change this.

Wi-Fi Adapter Power Management:

1. Device Manager → Wi-Fi adapter → Properties → Power Management tab.
2. Uncheck “Allow the computer to turn off this device to save power”.
3. Okay.

Advanced Power Settings:

1. Win + R → powercfg.cpl.
2. Current plan → “Change plan settings” → “Change advanced power settings”.
3. Expand Wireless Adapter Settings.
4. Set Power Saving Mode → “Maximum Performance”.
5. Apply → OK.

Specific settings for 5GHz:

Device Manager → Wi-Fi adapter → Properties → Advanced tab:

• “Sleep on WoWLAN Disconnect” → Disabled.
• “Wake on Magic Packet” → Disabled.
• “Wake on Pattern Match” → Disabled.

With these settings, the adapter will constantly scan for the 5GHz band.

Setting #7 – Uninstall and Reinstall the Wi-Fi Adapter

If Windows 11 still cannot detect the 5GHz Wi-Fi network after trying all the fixes mentioned above, the driver might be corrupted. A complete reinstallation is necessary.

Steps:

1. Device Manager → Network adapters → Wi-Fi adapter.
2. Right-click → “Uninstall device”.
3. Check the “Delete the driver software for this device” checkbox.
4. Uninstall.
5. Restart PC.

After the restart, Windows will install the generic driver.

After that, install the latest driver from the manufacturer:

• Intel adapters: Use Intel Driver & Support Assistant.
• Realtek/Qualcomm: From the laptop brand’s support website.

The 5GHz network should become visible after a fresh driver installation.

Router Side – Best Settings for the 5GHz Band

If everything is fine on the Windows side, optimize the router as well:

Channel Width:

• Set the channel width to 80MHz or 40MHz on the 5GHz band.
• Some devices cannot detect 160MHz.

Router admin → Wireless → 5GHz → Channel Width → select 80MHz.

WPA2/WPA3 Security:

• Never use an open network or WEP.
• Use WPA2-Personal or WPA2/WPA3 mixed mode.

Transmit Power:

• The 5GHz band has a shorter range.
• Set the Transmit Power to High or 100% in the router admin settings.

Disable Band Steering (if there is an issue):
Some routers have a Band Steering feature that automatically assigns the frequency band. This sometimes blocks the 5GHz band. Disable it and manually select 5GHz.

Laptop vs. Desktop PC – Some Extra Considerations

For laptop users:
If the laptop is new and has never detected a 5GHz signal, check whether the Wi-Fi adapter is actually dual-band. Budget laptops sometimes come with 2.4GHz-only adapters.

For desktop PC users:
A desktop might be equipped with either a PCIe Wi-Fi card or a USB Wi-Fi adapter.

• PCIe cards: These are usually dual-band – check the manufacturer’s spec sheet.
• USB adapters: Cheap USB adapters are mostly 2.4GHz only.

If you need 5GHz on your desktop and your current adapter doesn’t support it:

• TP-Link Archer T4E (PCIe) – $20–25 equivalent in India.
• ASUS USB-AC68 (USB 3.0) – $35–40 equivalent in India.

India-Specific 5GHz Wi-Fi Considerations

There are some specific points worth noting regarding 5GHz Wi-Fi in India:

TRAI and WPC Regulations:
In India, the Wireless Planning & Coordination (WPC) Wing of the Department of Telecommunications (DoT) governs Wi-Fi operations. India regulates certain channels within the 5GHz band.

Allowed 5GHz Channels in India:

• UNII-1 (36, 40, 44, 48) – Indoor use; most compatible.
• UNII-3 (149, 153, 157, 161, 165) – Suitable for outdoor use as well.
• DFS channels (52–144) – Some devices do not scan these.

Practical Advice:
If the router is on a DFS channel and Windows does not detect it, set the router to channel 36 or 149.

ISP Routers (Airtel, Jio, BSNL, ACT):
In India, the 5GHz band on ISP-provided routers is sometimes turned off by default or set to the wrong channel.

• Jio GigaFiber: Go to the admin panel at 192.168.29.1. Navigate to Wi-Fi → 5GHz and enable it.
• Airtel Xstream: Admin panel at 192.168.1.1. Go to Wireless → 5GHz. Prefer channels 36–48.
• ACT Fibernet: The admin panel varies depending on the router model; contact customer care to have 5GHz enabled.

5GHz Not Working – How to Perform a Hardware Test?

If software fixes don’t work and you need to determine if the problem lies with the hardware:

Test #1 – Check Using a Different OS:
Create a Linux Live USB (Ubuntu is free), boot from it, and check the Wi-Fi list. If 5GHz appears in Linux, the problem is with Windows. If it doesn’t appear, it could be a hardware issue.

Test #2 – Try an External USB Wi-Fi Adapter:
Connect an inexpensive dual-band USB Wi-Fi adapter (costing around $12–15) to your laptop. If 5GHz shows up using this, the issue lies with the internal adapter.

Test #3 – Test from a Different Location:
Test the 5GHz connection while standing very close to the router (1–2 meters away). 5GHz has a shorter range, so the signal may not be detected if the distance is too great.
