To switch to 2.4 GHz, connect to a separately named 2.4-GHz Wi‑Fi network. If your router shows only one network name, it is probably combining 2.4 GHz, 5 GHz and possibly 6 GHz with automatic band steering. In that case, your phone or computer usually cannot force the band; use the router’s app or administrator page to create a temporary 2.4-GHz network, enable an IoT/compatibility mode, or temporarily turn off the higher bands.
2.4 GHz is often preferable for older smart-home products and distant rooms because it generally travels farther and penetrates obstacles better. It is not automatically faster: 5 GHz and 6 GHz usually provide higher throughput at shorter practical range. See Microsoft’s band and home-layout guidance.
What “switch to 2.4 GHz” means
This changes the Wi‑Fi radio band, not your broadband plan or cellular service. “5G” in a Wi‑Fi name may be a user-created label and is not proof that the network is 5 GHz.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- 2.4 GHz: Usually longer range, better wall penetration and broad compatibility with older or low-power IoT devices; it is also more vulnerable to congestion.
- 5 GHz: Usually faster and less congested, but with shorter effective range.
- 6 GHz: Available only with compatible Wi‑Fi 6E/7 equipment and clients; it generally has the shortest range.
A dual- or tri-band router can broadcast all of these simultaneously. A device normally uses one band at a time, even when all bands share one network name. Google explains this behavior for Nest Wifi and Google Wifi systems at Google Home Help.

First, check whether the bands have separate names
Open the Wi‑Fi list on your phone or computer. You might see names such as HomeWiFi-2.4, HomeWiFi-5 and HomeWiFi-6. Network names are customizable, so labels are clues rather than proof. A single HomeWiFi could contain several bands, and a name containing “5G” could mean anything.
If the router or its app displays connected-client details, use that information to verify the actual band. Signal bars and the SSID alone cannot do so. Microsoft notes that one network name can represent multiple bands and that separate SSIDs make band identification easier: Wi‑Fi and your home layout.
Quickest method: join a separate 2.4-GHz network
- Open your device’s Wi‑Fi settings.
- Disconnect from, or temporarily forget, the network that keeps selecting the wrong band.
- Select the SSID designated for 2.4 GHz.
- Enter the Wi‑Fi password and wait for the connection to complete.
- Reopen the smart-device, printer or appliance setup app and repeat pairing.
After setup, reconnect your phone or computer to your normal network if you want. Changing a router’s Wi‑Fi name or password disconnects existing clients; they must be joined again with the new credentials (Google’s reconnection guidance).

Instructions by device
Android phones and tablets
- Open Settings.
- Choose Network & internet, Connections or Wi‑Fi, depending on the manufacturer.
- Tap the separately named 2.4-GHz SSID and enter its password.
Android has no universal system-level band selector. Vendor options such as “preferred band” or Wi‑Fi diagnostics are model-specific. For the standard procedure, see Google’s Android Wi‑Fi instructions.
iPhone and iPad
- Go to Settings → Wi‑Fi.
- Tap the separate 2.4-GHz network and enter the password.
- Return to the setup app.
iOS does not provide a general control to force 2.4 GHz when every band uses one SSID. For compatible Apple Wi‑Fi 6E networks, Apple generally recommends one network name across bands rather than permanent splitting (Apple’s Wi‑Fi 6E guidance).
Windows 10 and 11
- Select the Network, Sound or Battery icon on the taskbar.
- Open the Wi‑Fi network list.
- Select the 2.4-GHz SSID, choose Connect, and enter the password.
Windows normally cannot force 2.4 GHz when the router advertises one combined SSID. Some adapters expose Device Manager → Network adapters → your Wi‑Fi adapter → Properties → Advanced → Preferred Band. This setting is optional, driver-dependent, may only express a preference, and can be overridden by router steering. Microsoft’s general setup instructions are at Setting up a wireless network in Windows.

Mac
- Select the Wi‑Fi icon in the menu bar or Control Center.
- Choose the separately named 2.4-GHz network.
- Enter its password before opening the setup app.
A Mac generally cannot select a band inside a combined SSID. Check the router’s client list or app for confirmation. Apple describes automatic network decisions and router radio settings in About Wi‑Fi settings on Apple devices.
If there is only one Wi‑Fi name
Look in the router app or management page for Smart Connect, Band Steering, Unified SSID, Single SSID or Mesh steering. Exact labels vary by manufacturer.
- Find the router’s management address or open its official app.
- Sign in as administrator.
- Open Wi‑Fi, Wireless or Advanced Wi‑Fi.
- Temporarily disable the combined-band feature, or create a 2.4-GHz-only IoT network.
- Give the bands distinct names, such as
Home-2.4andHome-5, then apply the change. - Wait for Wi‑Fi to restart, join
Home-2.4, and complete setup. - Restore the combined configuration afterward if it normally works well for you.
Changing these settings can briefly disconnect every client. Keep Wi‑Fi security enabled; disabling encryption lets unauthorized users access your network and connected resources (Apple’s router security guidance).

Mesh Wi‑Fi and ISP-supplied routers
Mesh systems
Most mesh systems deliberately use one SSID and steer clients automatically. Their apps may offer a temporary 2.4-GHz compatibility mode, IoT network or device-specific band preference. Availability depends on model, firmware and operating mode. For example, some TP-Link Deco models support a client connection preference: TP-Link’s documentation.
If no control exists, try the manufacturer’s setup mode or temporarily disable higher bands. Moving the phone farther from the access point may cause it to roam to 2.4 GHz, but Google describes this only as a workaround, not a guaranteed selector.
ISP gateways
Provider apps may hide band controls behind names such as Smart Wi‑Fi, Whole Home Wi‑Fi or Pods. Identify the exact gateway model and firmware before following model-specific instructions. Do not factory-reset it as a first step; that can erase broadband settings.

When should you split the bands?
- Use a temporary split for one 2.4-GHz-only device or a setup app that cannot discover the product.
- Keep one combined SSID when everything works and you value automatic roaming and simpler administration.
- Use a dedicated IoT network when your router supports one and you have many smart devices. Confirm that local discovery still works; guest-network isolation can break casting, printing or app control.
Permanent separation can mean more passwords, less convenient roaming, slower phones stuck on 2.4 GHz, and additional printer, AirPlay, HomeKit or casting confusion. Separate SSIDs improve visibility and control, not necessarily performance.
Troubleshooting
The 2.4-GHz network is not visible
- Confirm in the product specifications that the device actually requires or supports 2.4 GHz.
- Restart Wi‑Fi on the phone or computer, then restart the router and target device.
- Check that the 2.4-GHz radio is enabled and that the router is not hiding it behind one SSID.
- Move close to the router during setup.
- Expose a separate 2.4-GHz SSID or use the manufacturer’s compatibility procedure.
The phone keeps selecting 5 GHz
Temporarily forget the 5-GHz SSID or turn off its auto-join option, if available. Otherwise, disable 5/6 GHz at the router or use a distinct 2.4-GHz SSID. Moving farther from the router can help a phone roam to 2.4 GHz, but it does not prove which band is active.
The smart device still will not pair
Verify the phone is on the intended SSID, the product is in pairing mode, the password is correct, and the app has any required Bluetooth, location and local-network permissions. Temporarily disconnect a VPN, check that the router’s security mode is compatible with the product, and clear old Wi‑Fi credentials on the device. Not every pairing failure is a band problem.
It connects but performs poorly
2.4 GHz can improve reach while reducing speed because of interference and congestion. Consider router placement, nearby interference, channel-width recommendations and a wired connection where practical. Apple notes that 20-MHz channel width on 2.4 GHz can improve reliability in crowded environments, but it is not a universal fix (Apple Wi‑Fi recommendations).
Other devices disconnected after the change
This is expected if you changed the SSID or password. Reconnect affected devices or restore the original credentials. If the router restarted, allow a few minutes for mesh nodes and clients to rejoin.
Bottom line
Join a separately named 2.4-GHz SSID when one exists. If all bands share one name, change the router—not the phone—to create temporary 2.4-GHz access or enable its compatibility/IoT mode. Restore your normal configuration after setup, and keep wireless security enabled.
