What Does This Error Mean?

Windows 11 PC
MacBook
iPhone
Android Phone

Common Causes

Your device's Wi-Fi adapter does not support 5GHz — it only works on 2.4GHz
The 5GHz radio on the router has been turned off in the settings
Your device is too far from the router — 5GHz has a shorter range than 2.4GHz
The router firmware has a bug causing the 5GHz band to drop
The Wi-Fi driver on your Windows PC is out of date

How to Fix It

First, check if your device supports 5GHz at all.

On Windows, go to Device Manager, find your Wi-Fi adapter, and look up its specs online. Older devices only support 2.4GHz.
Move your device closer to the router and scan for networks again.

5GHz has much shorter range than 2.4GHz. Walls and floors block it easily.
Reboot your router by unplugging it for 30 seconds, then plug it back in.

A glitch in the router firmware can disable the 5GHz band. A reboot usually restores it.
Log in to your router's admin panel and make sure the 5GHz radio is enabled.

Look under Wireless Settings for a section labeled 5GHz or 5G. Make sure it is turned on.
On Windows, update your Wi-Fi adapter driver.

Go to Device Manager, right-click your Wi-Fi adapter, and select Update Driver.

When to Call a Professional

If the 5GHz band disappears from the router admin panel entirely, the 5GHz radio chip may have failed. Contact your router manufacturer's support for warranty options.

Frequently Asked Questions

How do I know if my laptop supports 5GHz Wi-Fi?

Search your laptop model online and look at the Wi-Fi specs. If it says 802.11ac or Wi-Fi 5, it supports 5GHz. If it only says 802.11n or 802.11g, it likely does not.

Is 5GHz better than 2.4GHz?

5GHz is faster but has shorter range. 2.4GHz is slower but travels farther and through more walls. Use 5GHz when close to the router, 2.4GHz when farther away.

My phone sees 5GHz at home but not here. Why?

Some routers broadcast 5GHz only in certain channels. Older phones may not support all 5GHz channels. Try changing the router's 5GHz channel to 36 or 40 in the admin panel.
