Wi-Fi Error: Wrong Frequency Band / 5GHz Not Showing Up — What It Means & How to Fix It

What Does This Error Mean?

Most modern routers broadcast on two frequency bands: 2.4GHz and 5GHz. The 5GHz band is faster but has shorter range. If you cannot see the 5GHz network, or your device keeps choosing the slow 2.4GHz band, it is usually a distance problem, a device compatibility issue, or a router band steering setting.

Affected Models

Windows 10
Windows 11
macOS
Android
iOS
Wi-Fi 5 devices
Wi-Fi 6 devices

Common Causes

The device is too far from the router for the shorter-range 5GHz signal to reach
The device's Wi-Fi adapter only supports 2.4GHz (older devices)
The router has band steering enabled, automatically moving devices to the slower band
The 5GHz radio on the router has been accidentally disabled in router settings
The device's driver does not properly support dual-band selection

How to Fix It

Move closer to the router. The 5GHz band has significantly less range than 2.4GHz. Walls, floors, and distance can prevent the 5GHz signal from reaching your device even when 2.4GHz is available.

Test from the same room as the router first to confirm 5GHz is working before troubleshooting further.
Check if your device supports 5GHz. On Windows, open Command Prompt and type: netsh wlan show drivers — look for '5 GHz' in the supported bands list. If it is not listed, your adapter does not support 5GHz.

Older laptops and budget devices often have 2.4GHz-only adapters.
Check the router admin page. Log in and look at the wireless settings. Confirm that the 5GHz radio is enabled. Some routers let you disable individual bands.

It is easy to accidentally disable the 5GHz band when making other router setting changes.
Give the 5GHz network a different name than the 2.4GHz network. In router settings, change 'MyNetwork' on 5GHz to 'MyNetwork_5G'. This lets you manually choose which band to connect to.

Separate names give you full control over which band each device uses.
Update your Wi-Fi adapter driver. Dual-band support can be broken by outdated drivers. Download the latest driver from your laptop manufacturer's website.

Some older drivers have bugs that prevent proper 5GHz band scanning.

When to Call a Professional

Frequency band issues are almost always fixable through router settings or device settings alone. If the 5GHz radio is completely missing from the router admin page, the router hardware may have a fault. Contact your ISP if the router is provided by them — they can replace or remotely reconfigure it.

Frequently Asked Questions

What is the difference between 2.4GHz and 5GHz Wi-Fi?

Think of 2.4GHz as a long-range radio station with limited bandwidth. And 5GHz as a short-range station with much more bandwidth. 2.4GHz travels further through walls but is slower and more congested. 5GHz is faster and less congested but does not reach as far. For devices close to the router, 5GHz is always the better choice.

Should I use the same network name for both bands or different names?

Both approaches work, but separate names give you more control. With the same name (band steering), the router decides which band to use — and it does not always pick the best one. With separate names, you manually choose which band each device connects to. For performance-sensitive devices like gaming consoles and smart TVs, manually assigning them to 5GHz is beneficial.

What is Wi-Fi 6 and does it change which band I should use?

Wi-Fi 6 (802.11ax) is the latest Wi-Fi standard. It works on both 2.4GHz and 5GHz bands, and newer Wi-Fi 6E routers also add a 6GHz band. If you have a Wi-Fi 6 router and device, the 5GHz band is significantly faster than on older routers. The 6GHz band is the fastest of all but has the shortest range.
