Network setting in iphone

Update your network provider settings manually on your iPhone or iPad

Network provider settings updates let your network provider update the network and related settings to improve mobile network connectivity and performance. Network provider settings updates can also add support for new features, such as 5G or Wi-Fi Calling.

When a network provider settings update is available, you’ll be prompted to install it. Installation takes less than one minute, and you can keep using your device normally. If your network provider releases a mandatory update, you’ll see an OK button instead of an Update button to let you know that the update was downloaded and installed.

If you dismiss the installation notification, you can update network provider settings manually by following these steps:

1. Make sure your device is connected to Wi-Fi or a mobile network.
2. Tap Settings > General > About.
3. Follow the onscreen instructions to install your network provider update.

If you insert a new SIM card into your iPhone or iPad, you will need to download the network provider settings for your new network provider.

To see the version of network provider settings installed on your device, tap Settings > General > About and look next to Network provider. To see additional network provider information, tap the version number. To verify you have the latest network provider settings installed, contact your network provider.

Use private Wi-Fi addresses on iPhone, iPad, iPod touch, and Apple Watch

To improve privacy, your device uses a different MAC address with each Wi-Fi network.

To communicate with a Wi-Fi network, a device must identify itself to the network using a unique network address called a Media Access Control (MAC) address. If the device always uses the same Wi-Fi MAC address across all networks, network operators and other network observers can more easily relate that address to the device’s network activity and location over time. This allows a kind of user tracking or profiling, and it applies to all devices on all Wi-Fi networks.

Starting with iOS 14, iPadOS 14, and watchOS 7, your device improves privacy by using a different MAC address for each Wi-Fi network. This unique MAC address is your device’s private Wi-Fi address, which it uses for that network only.

In some cases, your device will change its private Wi-Fi address:

• If you erase all content and settings or reset network settings on the device, your device uses a different private address the next time it connects to that network.
• Starting with iOS 15, iPadOS 15, and watchOS 8, if your device hasn’t joined the network in 6 weeks, it uses a different private address the next time it connects to that network. And if you make your device forget the network, it will also forget the private address it used with that network, unless it has been less than 2 weeks since the last time it was made to forget that network.

Join Wi-Fi networks with a private address

Connect to Wi-Fi networks like you normally do. A private address doesn’t affect how you join or use most Wi-Fi networks, but if a network doesn’t allow your device to join, or doesn’t allow it further network or internet access after joining, you can turn off Private Address for that network.

Turn Private Address off or on for a network

Private Address is turned on by default. For improved privacy, leave it on for all networks that support it.

iPhone, iPad, or iPod touch

1. Open the Settings app, then tap Wi-Fi.
2. Tap the information button next to a network.
3. Tap to turn Private Address on or off. If your device joined the network without using a private address, a privacy warning explains why.
   

Apple Watch

1. Open the Settings app, then tap Wi-Fi.
2. Tap the name of the network you joined. If you haven’t joined the network yet, swipe left on its name and tap more .
   
3. Tap to turn Private Address on or off.
   

For network administrators

If you manage a Wi-Fi router that’s configured to notify you when a new device joins the network, you are notified when a device first joins with a private address.

Businesses and other organizations might need to update their Wi-Fi network security to work with private addresses. Or they can use an MDM-defined network profile to turn off Private Address for enrolled devices that join their Wi-Fi network. Learn more about private Wi-Fi addresses and enterprise.

If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network

Get help connecting to Wi-Fi on your iPhone, iPad, or iPod touch.

Make sure that your router is on and you’re within range

If you’re too far from your Wi-Fi router, you can’t get a signal, so make sure that you’re within range.

Make sure that Wi-Fi is on and you can see your network

Go to Settings > Wi-Fi and make sure that Wi-Fi is on. Tap the name of your Wi-Fi network to join. A blue checkmark beside a network name means that you’re connected.

If you see Auto Join Disabled under your Wi-Fi network name, tap it turn on Auto-Join.

If asked, enter your Wi-Fi password

If asked, enter the password for your Wi-Fi network. Get help if you don’t know your password.

Even if you enter the correct password, you might see an «unable to join the network» message or an «incorrect password» message. Restart all of your devices, then try to enter your password again.

Check for issues with your Wi-Fi network

If iOS detects an issue with your Wi-Fi connection, you might see a Wi-Fi recommendation under the name of the Wi-Fi network that you’re connected to. For example, you might see the alert «No Internet Connection.» To get more information, tap the Wi-Fi network.

Check your cables and connections

If you still can’t connect to your network or get online, make sure that your router is connected to the modem and turned on.

Restart

Try restarting your iOS device. Here’s how to restart your iPhone, iPad, or iPod touch.

Then restart your router, and cable or DSL modem. To restart your router or modem, unplug it, then plug it back in.

After you restart each device, see if you fixed the issue.

Still can’t connect?

Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.

View and edit your Access Point Name (APN) on your iPhone and iPad

Learn how to view and edit the APN for cellular data services on your iPhone and iPad.

The Access Point Name (APN) defines the network path for all cellular data connectivity. Some carriers require you to enter your APN settings to set up your cellular service.

You can only edit or view your APN on your iPhone and iPad if your carrier allows it. If you can’t modify your APN settings, contact your carrier.

Enter your APN settings automatically

If your cellular carrier supports this feature, you can populate your APN settings automatically in iOS 15 and iPadOS 15 and later:

1. Insert your SIM card.
2. On your iPhone or iPad, go to Settings > Cellular > Cellular Data.
3. Under Cellular Data, choose Use Carrier Settings.

If you don’t see the option to use carrier settings, follow the steps below to enter your APN settings.

View and edit your APN settings

If you enter incorrect APN settings, you might lose cellular data connectivity and receive additional charges. Don’t edit the APN unless directed by your carrier or mobile device administrator. Contact your carrier to verify the correct APN settings.

If your carrier allows it, you can view your APN settings in one of the following locations:

• Settings > Cellular > Cellular Data Options > Cellular Network
• Settings > Mobile Data > Mobile Data Options > Mobile Data Network

If your device doesn’t have either option, contact your carrier.

To change your settings, tap each field and enter the details from your carrier. The settings should save automatically. Depending on your carrier, you might not be able to change the cellular data settings. If your carrier needs a different APN setting, you might be able to use a configuration profile with the correct setting.

Unless you’re using a configuration profile, updating iOS resets any changes made to your APN settings. If you edit your APN settings before updating iOS, your settings will reset to the default values. You might need to reenter your settings after an iOS update.

Reset your APN settings

To revert to your carrier’s default APN information, go to Settings > Cellular > Cellular Data Network > Reset Settings. If you installed a configuration profile, the profile’s default information will be used instead.

If you’re using an iPhone or iPad in an enterprise environment, you might need to contact your mobile device administrator to change your APN. If you change APN settings that a mobile device administrator set for you from a configuration profile, here’s how to change it back:

• On iPhone: Go to Settings > Cellular > Cellular Data Network, then tap Reset Settings.
• On iPad: Remove the configuration profile and add it again.

If you’re a mobile device administrator, you can use Apple Configurator or another mobile device management solution to change the APN and other advanced settings.

Recommended settings for Wi-Fi routers and access points

For the best security, performance, and reliability, we recommend these settings for Wi-Fi routers, base stations, or access points used with Apple products.

This article is primarily for network administrators and others who manage their own network. If you’re trying to join a Wi-Fi network, one of these articles should help:

About privacy and security warnings
If your Apple device shows a privacy warning or weak-security warning about a Wi-Fi network, that network could expose information about your device. Apple recommends connecting to Wi-Fi networks that meet or exceed the security standards in this article.

Before changing the settings on your router

1. Back up your router’s settings, in case you need to restore them.
2. Update the software on your devices. This is critical to ensure that your devices have the latest security updates and work best with each other.
   • First install the latest firmware updates for your router.
   • Then update the software on your other devices, such as on your Mac and on your iPhone or iPad.
3. On each device that previously joined the network, you might need to forget the network to ensure that the device uses the router’s new settings when rejoining the network.

Router settings

To ensure that your devices can connect securely and reliably to your network, apply these settings consistently to each Wi-Fi router and access point, and to each band of a dual-band, tri-band, or other multiband router.

Security

Set to WPA3 Personal for better security
Set to WPA2/WPA3 Transitional for compatibility with older devices

The security setting defines the type of authentication and encryption used by your router, and the level of privacy protection for data transmitted over its network. Whichever setting you choose, always set a strong password for joining the network.

• WPA3 Personal is the newest, most secure protocol currently available for Wi-Fi devices. It works with all devices that support Wi-Fi 6 (802.11ax), and some older devices.
• WPA2/WPA3 Transitional is a mixed mode that uses WPA3 Personal with devices that support that protocol, while allowing older devices to use WPA2 Personal (AES) instead.
• WPA2 Personal (AES) is appropriate when you can’t use one of the more secure modes. In that case, also choose AES as the encryption or cipher type, if available.

Weak security settings to avoid on your router

Don’t create or join networks that use older, deprecated security protocols. These are no longer secure, they reduce network reliability and performance, and they cause your device to show a security warning:

• WPA/WPA2 mixed modes
• WPA Personal
• WEP, including WEP Open, WEP Shared, WEP Transitional Security Network, or Dynamic WEP (WEP with 802.1X)
• TKIP, including any security setting with TKIP in the name

Settings that turn off security, such as None, Open, or Unsecured, are also strongly discouraged. Turning off security disables authentication and encryption and allows anyone to join your network, access its shared resources (including printers, computers, and smart devices), use your internet connection, and monitor the websites you visit and other data transmitted over your network or internet connection. This is a risk even if security is turned off temporarily or for a guest network.

Network name (SSID)

Set to a single, unique name (case-sensitive)

The Wi-Fi network name, or SSID (service set identifier), is the name your network uses to advertise its presence to other devices. It’s also the name that nearby users see on their device’s list of available networks.

Use a name that’s unique to your network, and make sure that all routers on your network use the same name for every band they support. For example, don’t use common names or default names such as linksys, netgear, dlink, wireless, or 2wire, and don’t give your 2.4GHz and 5GHz bands different names.

If you don’t follow this guidance, devices might not connect reliably to your network, to all routers on your network, or to all available bands of your routers. And devices that join your network are more likely to encounter other networks that have the same name, and then automatically try to connect to them.

Hidden network

Set to Disabled

A router can be configured to hide its network name (SSID). Your router might incorrectly use ”closed” to mean hidden, and ”broadcast” to mean not hidden.

Hiding the network name doesn’t conceal the network from detection or secure it against unauthorized access. And because of the way that devices search for and connect to Wi-Fi networks, using a hidden network might expose information that can be used to identify you and the hidden networks you use, such as your home network. When connected to a hidden network, your device might show a privacy warning because of this privacy risk.

To secure access to your network, use the appropriate security setting instead.

MAC address filtering, authentication, access control

Set to Disabled

When this feature is enabled, your router can be set up to allow only devices that have specified MAC (media access control) addresses to join the network. You shouldn’t rely on this feature to prevent unauthorized access to your network, for these reasons:

• It doesn’t prevent network observers from monitoring or intercepting traffic on the network.
• MAC addresses can easily be copied, spoofed (impersonated), or changed.
• To help protect user privacy, some Apple devices use a different MAC address for each Wi-Fi network.

To secure access to your network, use the appropriate security setting instead.

Automatic firmware updates

Set to Enabled

If possible, set your router to automatically install software and firmware updates as they become available. Firmware updates can affect the security settings available to you, and they deliver other important improvements to the stability, performance, and security of your router.

Radio mode

Set to All (preferred), or Wi-Fi 2 through Wi-Fi 6 (802.11a/g/n/ac/ax)

These settings, available separately for the 2.4GHz and 5GHz bands, control which versions of the Wi-Fi standard the router uses for wireless communication. Newer versions offer better performance and support more devices concurrently.

It’s usually best to enable every mode offered by your router, rather then a subset of those modes. All devices, including older devices, can then connect using the fastest radio mode they support. This also helps reduce interference from nearby legacy networks and devices.

Bands

Enable all bands supported by your router

A Wi-Fi band is like a street over which data can flow. More bands provide more data capacity and performance for your network.

Channel

Set to Auto

Each band of your router is divided into multiple, independent communication channels, like lanes in a street. When channel selection is set to automatic, your router selects the best Wi-Fi channel for you.

If your router doesn’t support automatic channel selection, choose whichever channel performs best in your network environment. That varies depending on the Wi-Fi interference in your network environment, which can include interference from any other routers and devices that are using the same channel. If you have multiple routers, configure each to use a different channel, especially if they are close to each other.

Channel width

Set to 20MHz for the 2.4GHz band
Set to Auto or all widths (20MHz, 40MHz, 80MHz) for the 5GHz band

Channel width specifies how large of a ”pipe” is available to transfer data. Wider channels are faster but more susceptible to interference and more likely to interfere with other devices.

• 20MHz for the 2.4GHz band helps to avoid performance and reliability issues, especially near other Wi-Fi networks and 2.4GHz devices, including Bluetooth devices.
• Auto or all channel widths for the 5GHz band ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in the 5GHz band.

Set to Enabled, if your router is the only DHCP server on the network

DHCP (dynamic host configuration protocol) assigns IP addresses to devices on your network. Each IP address identifies a device on the network and enables it to communicate with other devices on the network and internet. A network device needs an IP address much like a phone needs a phone number.

Your network should have only one DHCP server. If DHCP is enabled on more than one device, such as on both your cable modem and router, address conflicts might prevent some devices from connecting to the internet or using network resources.

DHCP lease time

Set to 8 hours for home or office networks; 1 hour for hotspots or guest networks

DHCP lease time is the length of time that an IP address assigned to a device is reserved for that device.

Wi-Fi routers usually have a limited number of IP addresses that they can assign to devices on the network. If that number is depleted, the router can’t assign IP addresses to new devices, and those devices can’t communicate with other devices on the network and internet. Reducing DHCP lease time allows the router to more quickly reclaim and reassign old IP addresses that are no longer being used.

Set to Enabled, if your router is the only device providing NAT on the network

NAT (network address translation) translates between addresses on the internet and addresses on your network. NAT can be understood by imagining a company’s mail department, where deliveries to employees at the company’s street address are routed to employee offices within the building.

Generally, enable NAT only on your router. If NAT is enabled on more than one device, such as on both your cable modem and router, the resulting ”double NAT” might cause devices to lose access to certain resources on the network or internet.

Set to Enabled

WMM (Wi-Fi multimedia) prioritizes network traffic to improve the performance of a variety of network applications, such as video and voice. All routers that support Wi-Fi 4 (802.11n) or later should have WMM enabled by default. Disabling WMM can affect the performance and reliability of devices on the network.
