5GHz WiFi Not Showing Up? How to Fix It Fast
If your 5GHz network does not appear, the cause is your device, the router band settings or the channel. Here is how to fix each.
If you only see the 2.4GHz network, or your 5GHz network has disappeared, there are only a few possible causes: your device does not support 5GHz or the chosen channel, the 5GHz band is off or merged in the router, or a driver setting is blocking it.

Work through the checks in order, and most people fix it within a few minutes.

Fixes in order
- Check device support. Older phones, smart plugs and cheap laptops may be 2.4GHz only. Search your model with “5GHz” or “802.11ac”.
- Check if the router merges bands. Many routers use one name for both bands (band steering). The 5GHz network will not show separately. Split the names in WiFi settings to see it.
- Turn the 5GHz radio on. Log in to the router and make sure the 5GHz wireless is enabled.
- Change the 5GHz channel. Some devices do not support DFS channels 52 to 144. Set a channel in 36 to 48 or 149 to 165.
- Set the region correctly. A wrong country setting can enable channels your device will not use.
- Update the WiFi driver on Windows, then in Device Manager, Advanced, set Preferred Band to 5GHz and check that 802.11ac or ax mode is enabled.
- Move closer. 5GHz has a shorter range and is blocked more by walls.
- Restart the router after changes, then forget and rejoin the network.
The channel check is the one that fixes it most often for me.
5GHz channel guide
| Channels | Notes |
|---|---|
| 36 to 48 | Supported by almost every 5GHz device |
| 52 to 144 (DFS) | Shared with radar, some devices skip them |
| 149 to 165 | Supported in the US and many countries, not all |
The 36 to 48 range is the one I start with on any device.
Still not showing?
- Try another device to see whether the router is broadcasting 5GHz at all.
- Reset the router WiFi settings or update the firmware.
- Some ISP gateways disable 5GHz in certain modes. Check the provider app.
When nothing shows, the provider app is the place I check next.
Does your device support 5 GHz?
The most common reason 5 GHz doesn’t show up is simple: the device doesn’t have a 5 GHz radio. Budget laptops, older phones and many smart-home gadgets are 2.4 GHz only.
- Windows: run
netsh wlan show driversand look at Radio types supported. If you see 802.11a, ac or ax, it supports 5 GHz. - Android: check the phone’s spec sheet for “dual-band” or “WiFi 5/6”.
- Smart devices: almost always 2.4 GHz only.
A missing 5 GHz radio is the answer I find most often on older laptops.
Router settings that hide 5 GHz
- 5 GHz radio switched off in wireless settings.
- Smart Connect or band steering combining both bands under one name, so you never see a separate 5 GHz network.
- A DFS channel that some devices don’t support, like channels 52 to 144.
- Country or region setting on the router that doesn’t match your location.
Setting the 5 GHz channel to 36, 40, 44 or 48 fixes visibility for many devices. Band steering is the setting I check first when the 5 GHz name never appears.
Set your router’s region correctly
Routers limit which 5 GHz channels they use based on the country setting. If the router is set to the wrong region, or your device was bought abroad, they may not share any channels.
- Log in to the router and find the region or country setting in wireless or system settings.
- Make sure it matches where you live.
- Set 5 GHz to a common channel like 36 or 40.
- Restart the router and scan again.
A router bought abroad is the case where I check the region first.
5 GHz on smart-home setups
If you’re trying to set up a smart plug or camera and can’t see your 5 GHz network on it, that’s expected. Almost all smart-home devices use 2.4 GHz only. Make sure 2.4 GHz is on, and if the setup app complains, temporarily give 2.4 GHz its own network name.
Smart plugs are the devices I expect to stay on 2.4 GHz.
