To connect your iPhone to 2.4 GHz Wi-Fi, open Settings > Wi-Fi and join a network configured to broadcast only on 2.4 GHz. If your router combines several bands under one name, use its supported controls to separate the bands, create a dedicated network, or temporarily restrict the connection.
The short version
- Start with the network: Join a confirmed 2.4 GHz network through Settings > Wi-Fi.
- One shared name: Use your router’s supported band controls when multiple bands share the same network name.
- Smart device setup: A temporary band restriction or dedicated 2.4 GHz network can provide the connection you need.
- Hotspot distinction: Maximize Compatibility changes the hotspot an iPhone broadcasts, not its connection to your router.

Join an existing 2.4 GHz network
Open Settings > Wi-Fi and turn on Wi-Fi. Tap the network name that your router owner has confirmed uses only 2.4 GHz, then enter its password if requested. A blue checkmark confirms the connection, but a name containing “2.4” is only a naming convention and does not prove the band.
For a hidden network, open Settings > Wi-Fi, turn on Wi-Fi, and tap Other. Enter the network name, security type, and password supplied by its administrator. The network must be configured for 2.4 GHz; entering a shared multiband name does not select a frequency.
To join through nearby Apple password sharing, select the confirmed network in your iPhone’s Wi-Fi settings. Keep the sharing iPhone unlocked and connected to that network, then tap Share Password on that phone when prompted. Both devices must be within Bluetooth and Wi-Fi range, have each other in contacts, and not be using Personal Hotspot.
On an iPhone running iOS 27 that holds the credentials, open Passwords > Wi-Fi and select the confirmed network; you can also find saved passwords on your iPhone when you need the stored login. Tap Show Network QR Code, then scan the displayed QR code with a receiving iPhone that supports Wi-Fi QR codes. Password sharing and QR codes supply network credentials, so neither forces 2.4 GHz when that name broadcasts on multiple bands.
Separate bands that share one network name
On a supported TP-Link router, connect to the router, open the router administration page, and sign in with its administrator credentials. Open Advanced > Wireless > Wireless Settings, then disable Smart Connect. Give the 2.4 GHz network a different name from the other bands and select Save.
Turning off Smart Connect alone does not necessarily change the names. Return to Settings > Wi-Fi on your iPhone and join the 2.4 GHz name.
For a Tether-compatible TP-Link router supporting Smart Connect, open Tether, select your router, and sign in. Open More > Wi-Fi Settings > 2.4GHz & 5GHz Network. Turn off Smart Connect, assign different names to the bands, and tap SAVE, then join the 2.4 GHz name in your iPhone’s Wi-Fi settings.
For an eligible Xfinity gateway, sign in to the Xfinity app and tap WiFi. Open View WiFi equipment or WiFi details, then tap Edit WiFi settings. Turn on Split bands, give the bands different names, and tap Save, then join the 2.4 GHz name through Settings > Wi-Fi.
Xfinity’s option depends on your gateway and extender configuration, while TP-Link’s controls depend on model and firmware. If these controls are missing, use a supported restriction or dedicated network option below. Without administrator access, ask the network owner to provide a 2.4 GHz network.
Restrict the bands during smart device setup
On a supported eero network, open the eero app and go to Settings > Troubleshooting. Tap My device won’t connect, then tap My device is 2.4 GHz only. Tap Pause 5 GHz and 6 GHz, then connect your iPhone while the network broadcasts only on 2.4 GHz.
Complete the smart device’s setup during the pause. The higher bands return automatically after 10 minutes, or you can tap Cancel to restore them sooner.
On supported Deco models, connect to Deco and open the Deco app. Go to More > Wi-Fi Settings > Advanced > Band, select 2.4GHz only, and save the settings. Reconnect your iPhone, addressing any separate 6 GHz band settings as well.
Disabling router radios changes the network for everyone and can disconnect devices using those bands. On a TP-Link router with independent radio controls, sign in to its administration page and open Advanced > Wireless > Wireless Settings. For each unwanted higher-frequency band, uncheck Enable, or uncheck Enable Wireless Radio on models using that label.
Keep 2.4 GHz enabled, select Save, and reconnect your iPhone. Re-enable the other radios afterward if you needed the restriction only for setup.
For an eligible Spectrum-managed router, sign in to your Spectrum account and, under Your Services, select Internet. Select Setup Smart Device (2.4 GHz), then select Switch to 2.4 GHz. Return to the smart device’s app to continue setup.
These options depend on the router, firmware, and account features available to you. If your setup lacks the relevant control, use a supported dedicated network option or ask the administrator to configure one.
Create a dedicated 2.4 GHz IoT network
On a TP-Link router supporting IoT Network, sign in to its browser administration page and open Advanced > Wireless > IoT Network. In the 2.4GHz section, check Enable. Set a distinct network name, security type, and password, click SAVE, then join that network on your iPhone.
In Tether, select a compatible router and open More > IoT Network > 2.4GHz IoT Network. Turn on 2.4GHz IoT Network and configure its Network Name, Password, and security type. Join the network through Settings > Wi-Fi on your iPhone.
On a Deco model supporting this feature, open the Deco app and go to More > IoT Network. Enable IoT Network, set its network name and password, then tap Security and choose a supported protected mode. Tap Bands and enable only the 2.4 GHz band, then connect your iPhone to the new network.
Older Deco app layouts express the band choice as 2.4 GHz Only. If your model lacks IoT Network, use its main-network band control or connection preference when supported.
On supported Orbi WiFi 6E and selected WiFi 7 systems, use a device connected to Orbi to open the router’s administration page and sign in with administrator credentials. Select Wireless, then under Wireless IoT Settings, select Enable IoT Network and click Apply. Under Wireless IoT Settings, select 2.4GHz only and click Apply again. On your iPhone, open Settings > Wi-Fi and join the IoT network using its configured credentials.
Use a Deco guest network when suitable
On a supported Deco model, open More > Guest Network > Turn On Guest Network. Create a password, tap Done, and set the network name. Open Advanced > Band, select 2.4 GHz Only, then return and tap Save. Join that network on your iPhone.
Guest-network isolation can prevent your iPhone from communicating with smart devices on the main network. Deco isolates guest and main networks in Router mode, while supported Access Point mode configurations offer Allow Local Access. If setup requires communication with a device on the main network, use a suitable main-network option or the local-access control where supported.
Choose a device preference or check your Google network
On supported Deco models and firmware in Router or Access Point mode, open the Deco app and select Online Clients. Choose your iPhone and tap Specified Connection. Choose the preferred Deco and the 2.4 GHz Wi-Fi band, then tap Save.
TP-Link also calls this feature Connection Preference, while its detailed instructions use Specified Connection. Treat the selection as a preference rather than an unconditional permanent lock.
For Google Wifi, Nest Wifi, or Nest Wifi Pro, keep your iPhone connected and move farther from the router and mesh points. Google describes this as a way to encourage a phone to move to 2.4 GHz, but success depends on location. Check the band in Google Home under Wi-Fi > Devices > your iPhone > Info.
Continue smart device setup once that screen shows a 2.4 GHz connection. Moving closer again can cause another band change. If your iPhone stays on a higher band, use a confirmed 2.4 GHz network available to you or ask the network administrator for one.
Keep your iPhone on the separately named network
If your iPhone automatically returns to a separately named 5 GHz or 6 GHz network, open Settings > Wi-Fi > Edit. Tap the More Info button beside that network, turn off Auto-Join, and join your 2.4 GHz network. This controls network selection rather than band selection within a shared name.
Forgetting a network removes its saved connection, and with iCloud Keychain the removal can propagate to other devices using the same Apple Account. To forget a separately named higher-band network, open Settings > Wi-Fi > Edit and tap its More Info button. Tap Forget This Network, tap Forget, then join the 2.4 GHz network.
Forgetting a shared multiband name removes the whole network, including its 2.4 GHz connection. Some managed networks restrict automatic-joining controls, and some supervised devices or managed networks prohibit forgetting. If those controls are restricted, ask the administrator to provide the appropriate connection.
Use a second iPhone as a 2.4 GHz hotspot
The hosting phone must be an iPhone 12 or later with a carrier plan supporting Personal Hotspot. On that phone, turn on Personal Hotspot by opening Settings > Personal Hotspot and enabling Allow Others to Join. Turn on Maximize Compatibility and keep that screen open during connection.
On your receiving iPhone, open Settings > Wi-Fi, select the host’s network name, and enter its Wi-Fi password. Apple says Maximize Compatibility disables higher hotspot bands and uses 2.4 GHz. The connection uses the host’s cellular service; enabling the setting on your receiving iPhone does not change its connection to your home router.
Ask an administrator to configure your connection
For compatible UniFi access points, have the administrator open UniFi Network and go to Settings > WiFi. They can configure the intended network and retain only 2.4 GHz under WiFi Band, then have you join that network. Administrators can provide the same result on other platforms with equivalent band controls.
For an enrolled iPhone, have the administrator configure a Wi-Fi management payload with Service Set Identifier set to the already-created 2.4 GHz network name. They must configure the appropriate Network authentication type, optionally enable Auto Join, and deploy the payload to your iPhone. Management-console paths vary by provider, and the payload selects a network name rather than a frequency within a multiband network.
Frequently Asked Questions
Does turning off Wi-Fi 6E mode force your iPhone onto 2.4 GHz?
Turning off Wi-Fi 6E mode excludes 6 GHz. It does not exclude 5 GHz or force a 2.4 GHz connection.
Does hiding the 5 GHz network name disable that band?
The router’s radio controls determine whether that band broadcasts.
Which bands does an Orbi IoT network use by default?
On Orbi systems with the documented IoT band selector, the IoT network defaults to both 2.4 GHz and 5 GHz. Enabling that network alone therefore does not restrict it to 2.4 GHz.
Which enrollment types support managed Wi-Fi settings on iPhone?
Apple supports the Wi-Fi management payload through User Enrolment, Device Enrolment, and Automated Device Enrolment. Your administrator can use the applicable enrollment method to deploy the network configuration.
