If your router broadcasts two network names and one is labeled 2.4 GHz, select that name and enter its password. If it broadcasts only one name, the router is probably combining both bands and choosing one for each device. In that case you need to look in the router’s app or admin settings for a band steering or Smart Connect feature, or for an option to give each band its own name. The exact labels depend on the router brand, model and firmware version.
Step 1: Check whether your router has a separate 2.4 GHz network
Many routers create one network per band. Those networks appear as separate entries in the Wi-Fi list, so you can choose the band yourself. Microsoft’s Windows Wi-Fi troubleshooting guidance (Microsoft Support, “Fix Wi-Fi connection issues in Windows”) notes that the bands may appear as separate networks and suggests trying the other band when a connection fails.
- Open the Wi-Fi list on the device. On Windows, select the network icon in the taskbar. On iPhone, Android, or a Mac, open the Wi-Fi settings and view the available networks.
- Look for an entry labeled 2.4 GHz. If the router uses a naming suffix instead of the words, check the router app to confirm which name belongs to the 2.4 GHz band.
- Select that network and enter its password.
- Confirm the connection. Use the network details your device shows for the connected network. If the device stays on a 5 GHz name, the device is probably connected to a different network entry, so select the 2.4 GHz name again and reconnect.
Step 2: If there is only one network name
A single name usually means the router combines the 2.4 GHz and 5 GHz radios under one SSID. The router or the device then picks a band. Many such devices offer no manual band selector, so the setting you need is on the router, not the phone or computer. Vendor documentation describes this behavior, and the menu names differ by brand.

TP-Link routers: Smart Connect
TP-Link describes Smart Connect as a feature that automatically combines the bands under one name and assigns devices to the appropriate band. Access the router through the TP-Link management app or the router’s web page and look in the wireless settings for Smart Connect. Availability depends on the model. Where the model allows it, turning Smart Connect off lets you give each band its own network name, and the 2.4 GHz name then becomes selectable on your devices.

ASUS routers: Smart Connect
ASUS documents Smart Connect as a feature that selects an appropriate band for each client. In the router’s web interface, check the wireless settings for Smart Connect and for the band-specific network names. As with TP-Link, the exact screens depend on the model and firmware. If your model lets you disable Smart Connect, you can assign separate names to the 2.4 GHz and 5 GHz bands.
Google Wifi and Nest Wifi: one name by design
Google’s Home and Nest Help material says these systems use one network name across their active bands and direct devices to a band automatically. You cannot pick the band from the phone’s Wi-Fi list, and the Google Home app does not provide a manual band switch. If a phone used during setup cannot switch bands and you need 2.4 GHz, Google suggests moving that phone farther from the router or access points so it may connect on 2.4 GHz. This applies to those systems specifically.

Step 3: When 2.4 GHz still does not appear
If you have checked the router and no 2.4 GHz option shows up on the device, work through these causes in order:

Microsoft’s Windows troubleshooting material notes that an adapter can be limited to particular bands. Check the adapter specifications from the computer or adapter maker, or the wireless adapter details in Windows Device Manager, before assuming the router is the problem.
- A compatible USB Wi-Fi adapter may be a remedy. If the built-in adapter lacks 2.4 GHz support, an external adapter that supports it can work, but confirm compatibility with your operating system and your router before you buy.
- The device may be too far from the router. 2.4 GHz covers more distance and passes through walls better, so a device in a distant room may see only the 2.4 GHz network or perform better on it after you move closer to the router.
- The 2.4 GHz band may be turned off or restricted. Check the router’s wireless settings. On a managed network, such as one provided by an internet service provider or a property administrator, the band may be locked, and you may need to ask the administrator to change it.
Why you might want 2.4 GHz rather than 5 GHz
Microsoft’s home Wi-Fi guidance (Microsoft Support, “Wi-Fi and your home layout”) describes 2.4 GHz as offering longer range and better penetration through obstacles, and 5 GHz as offering faster speeds with more non-overlapping channels. These are general descriptions of the two bands, not guaranteed performance figures. A 2.4 GHz connection is usually the better choice for a device that sits far from the router, sits behind walls, or does not support 5 GHz. A 5 GHz connection is usually better for close, high-throughput uses such as streaming or large file transfers.

Should you split the network names permanently?
Splitting a combined network into separate band names makes manual selection possible, but it changes how every device on the network joins. Apple’s support guidance recommends using the same network name for each band so that Apple devices can connect reliably. Before making a permanent change, compare the trade-offs:
| Consideration | Separate names (one per band) | One combined name |
|---|---|---|
| Choosing 2.4 GHz manually | Yes, select the 2.4 GHz name on each device | Not on most devices; the router or device chooses the band |
| Automatic band steering | Not used; each device stays on the name it joined | Provided by the router, depending on the model |
| Apple devices | Contrary to Apple’s advice to use the same name for each band | Matches Apple’s recommendation for reliable connections |
| Google Wifi or Nest Wifi | Not how these systems are designed to operate | Google’s design: one name across active bands |
| Changing an existing network | Devices joined to the old name must reconnect to the new name | No name change needed |
For a single problem device, a temporary change is the usual approach. If you need 2.4 GHz only for one device, you can often select the 2.4 GHz name on that device while leaving the rest of the network unchanged, provided your router offers a separate name for that band.
