Why won’t I receive Internet access from my iPhone

iPhone is connected to Wi-Fi but using 3G/4G internet. Doesn’t work with open networks

Another strange problem with iPhone Wi-Fi. Once connected to a Wi-Fi network, the Wi-Fi icon does not appear in the status bar, but displays 3G, or 4G (may be EDGE, or LTE) and applications use the mobile Internet connection (if enabled). not over the wireless network. And if the cellular network is disabled, the internet does not work at all. Although there is a network connection.

From what I have seen, this happens most often when the iPhone is connected to a public, open Wi-Fi network. Subway, stores, cafes, restaurants, etc. д. These public networks are not password-protected, and iPhone identifies them as “Unsafe network. But it must work from the Wi-Fi network, not the 3G network.

When “Cellular Data” is enabled on the iPhone, after connecting to Wi-Fi, the connection should be used exactly by Wi-Fi. It is logical, why would you want to use a slower (though not always) connection and possibly pay for it, if you are connected to a wireless network?

But if our iPhone does not like the Wi-Fi network to which we are connected, then it continues to transmit data via cellular network (this we can see by the icon 3G or 4G ). And everything would be fine, but here it is very finicky. Refuses to work with those networks that other mobile devices have no problem connecting to and using internet access.

As I wrote before, this most often happens when connecting to unprotected networks. I saw several Комментарии и мнения владельцев on the website saying that the iPhone did not want to connect to unprotected networks. The ones without a password. Or connects to them, but the Internet does not work. The problem seems to have appeared after the update to iOS 11.3.

In the screenshot below you can see that the phone is connected to the MT_FREE network, there is a message “Unsafe network” (because the network is unsecured). But there is no “Wi-Fi” icon.

The thing is, even though there is “Insecure network”, there should be access to the internet. It’s not an error, it’s just a warning.

I’ve tried experimenting too. It’s hard to understand the logic of how the iPhone manages the internet connection at all. It either connects to the network and immediately disconnects, or does not connect at all and uses mobile Internet. Or there is a network connection, but when I try to open a website in the browser, it switches to EDGE (I just don’t have 3G here).

Yes, all of these open Wi-Fi networks are busy, and usually have several times more customers than are calculated. For this reason, Wi-Fi can work poorly, or not work at all. But judging by the reviews, with other devices everything is fine, but the iPhone is “capricious. Let’s try to figure it out. I don’t know many solutions at this point, but hope for feedback in the Комментарии и мнения владельцев. Share your observations!

If you are connecting from an iOS device:

Congratulations, you have set the DHCP manual settings and now you can enjoy the Wi-Fi connection.

How to share Wi-Fi on the iPhone

If the Internet connection is good, you can create an access point. To do this, you will need to go to “Settings” (this icon is framed in red in Fig. 1).

Going to “Settings”, click on the option “Modem mode” This is the mode that “turns” our iPhone into a device for sharing the Internet, a modem, or, if you prefer, into a router.

The first time you turn on the modem mode, set a password, which will connect our other devices (computer, laptop, other gadgets) to your iPhone as a Wi-Fi access point. To do this, click on “Wi-Fi password” :

When you turn on the modem mode later, you don’t need to enter the password in the iPhone. This password remains so until the user wants to change it.

  • Unauthorized connections of “alien” gadgets, laptops, or computers to the Wi-Fi network distributed by the iPhone;
  • Passing on the password to unauthorized people, for example, at their request to connect to the Internet with your iPhone in an emergency.

That is, you must change the password when it has become known to unauthorized persons.

Password should be entered in the password field (number 1 in the picture). 4). It should consist of Latin letters (capital and small) and numbers.

It is desirable to make the password long, about 10-15-20 characters, so that it would not be easy to pick up those who want to “free” to connect to your access point, to your iPhone. After entering the password, click on “Done” (figure 2 in Fig. 4) to finish the action.

So, if the password is entered, you can turn on the modem mode, and thus turn the iPhone into a Wi-Fi access point. To do this, switch the “Modem Mode” switch to the “On” position (the green color of the switch in Fig. 5).

In order for iPhone’s Wi-Fi handoff to take place, you still need to turn on the Wi-Fi switch. The iPhone automatically prompts you to do this when you turn on modem mode

But if before turning on the modem mode, you will not get such an offer, because at the moment of turning on the modem mode on your iPhone, the Wi-Fi will already be on.

Why is the “modem mode” function missing

There are several reasons why the router function may not turn on your iPhone:

  • No connection to the cell tower No network.
  • Software failure.
  • Incorrect data for network usage.
  • No APN settings for your service provider. Although most companies provide access without settings, they can come in handy for using your smartphone as a router.
  • Operating system update. For this reason, owners find that modem mode is missing. There’s an explanation: when the software is updated, all configuration data can be reset.
  • The communication module has burned out.

If you can use normal LTE, but at the same time the router function is absent, it cannot be due to the faulty module or other hardware defects. It is likely that the reason for this lies in the wrong settings, and you can fix them yourself.

How to fix the error

Most often the user notes that in the settings of iPhone, there is no modem mode reset network settings, including the parameter of access to the Internet, as a result you can not use it. To correct the problem it is sufficient to enter the correct APN data parameters, and then enable the modem function to transmit and receive signals.

  • Go to “Settings”, through “Cellular communication” go to “Data transfer.
  • Click on the “Modem Mode” section, enter the APN value.
  • Reboot the device after previously saving all entered information.
  • Go to the main settings page and move the slider next to “Mode” to the right to activate it.
  • Find an access point from another device and connect to it, so you can use your iPhone to access the Internet.

The main reason why an operator blocks internet access from the phone

Operators MTS, Beeline, Tele2, MegaFon, Yota, etc. д. Now they are actively blocking internet distribution from your phone to other devices. The conditions of these restrictions may be different for all operators and tariff plans. Operators either limit the possibility to distribute the internet at all, or ask for additional fees. For example, in a popular plan “Unlimited” (which may soon be gone altogether). Unlimited internet access, allows only 100 MB in modem mode. Some operators block the download of torrents, or limit the speed. Forbid the use of SIM-cards in modems, routers or tablets. But that’s another story. All this is done in order to take the load off the base stations. And of course to earn more money.

The most popular variants:

  • We distribute Wi-Fi from the phone to a laptop, computer or other device and it has no access to the Internet. Internet does not work. Internet on the phone works. The same story with charging via USB and Bluetooth.
  • The phone distributes the Internet for some time (a certain amount of traffic) and then will receive SMS warning that this service will be charged additionally. Can receive SMS immediately. (Depending on the operator and tariff plan).
  • Downloading torrents does not work.
  • The speed drops drastically after using a certain amount of Internet traffic.

For example: in the description of the “unlimited” tariff plan “Unlimited” from Tele2, it is clearly written that: “Distribution of traffic via Wi-Fi, Bluetooth, USB is not available on the tariff plan.”

The problem is also that most carriers do not specify in their tariff descriptions the rules for using Internet traffic. You can distribute it to other devices, or not. is unclear. This information is usually written in small print in an attached PDF file that almost no one reads. Here’s an example, as this information is listed in the detailed description of the tariff “Tarifische” from MTS:

On this tariff you can distribute only 10 GB of traffic. only after a paid service.

How operators limit Internet traffic distribution?

Previously it was mostly determined by TTL. When we distribute the Internet to another device with an Android-smartphone, or iPhone, the traffic package that passes through the smartphone is changed by 1. This is how the operator determines the forbidden action and takes certain measures: blocks the traffic, or removes an additional fee. But since this method can be bypassed, there are a lot of instructions on the Internet on this subject, the operators began to use additional technologies to analyze the traffic.

And judging by how many (with circumvention schemes set up) have recently (around March 2020) stopped distributing the Internet, then at least MTS (at the moment) still seriously improved its technology to identify “violators.

What to do?

  • Study in detail the terms of your tariff plan! It is very important to find out if the operator really limits the distribution of traffic from the phone, and for this reason the Internet does not work on your computer (and on the phone works!). Or the reason is something else.
  • Pay for the ability to distribute the Internet to other devices (if available under the terms of the tariff plan).
  • If possible connect to the cable internet, choose and buy a modern Wi-Fi router and not torture your smartphone.
  • Look for a way to bypass the blocking. You can try this on your Android phone as well as on your iPhone. But I do not support and do not recommend doing it! In addition, it is some complicated settings, constantly something falls off, does not work, etc. д.

Possible problems with the modem mode and their removal

There are many root causes that answer the question of why the modem mode on the iPhone suddenly disconnects. Malfunctions in the settings of the hardware lead to a failure.

Incorrect data entry for communication with the operator

Once the SIM-card is installed, the equipment automatically takes all the network parameters provided by the service provider, and after activating them can go to the World Wide Web. But sometimes there are obstacles that interfere with the normal operation of the process.

To exclude malfunction it is necessary to check APN debugging for mobile operator:

  • Enter “cellular data” section in settings.
  • Go to the subsection “cellular data network
  • Clarify the correctness of the written values depending on the service provider: MTS, Megafon, Bilain, Tele2.
  • If the parameters are entered incorrectly, the correction is done manually.

Enabling and disabling the “cellular data” section

The phone modem uses them to distribute the Internet. When the connection through the MacBook to any site begins to use traffic.

receive, internet, access, iphone

Disconnecting and reconnecting via cellular service allows you to correct an accidental error that prevents the normal functionality of the modem mode.

Checking carriers

Not all service providers have the internet sharing functionality, even one operator often has different features for different plans. If modem mode does not work on the cell phone, you should study your own tariff plan or connect an additional service.

Service providers have separate offers for “laptops” or “modems”; they are more expensive than standard ones, but give you unlimited Internet access. The user can clarify in advance with the operator whether he has such a service.

Restarting iPhone

This procedure solves a lot of problems with malfunctions. After turning off the device the system will automatically perform debugging, correcting defects. Process is slightly different for different phone generations.

  • iPhone SE. the first generation, up to the 5th model: you must press the top button until the sentence “off” appears, then move the slider and wait half a minute, to connect again press the same key, until the brand logo appears;
  • iPhone SE. second generation 6, 7, 8: the side button is held down until the off flag appears on the display, you must move it and wait 30 seconds, then reactivate the device.

For iPhone X, 11, 12 press the side and volume buttons, until the slider appears, the rest of the actions are similar to previous versions.

Reset the network settings of your cell phone

Reset to factory defaults to resolve device software problems. Once performed, the self-deletion and elimination of the source of the problem takes place.

The task is performed according to the standard scheme:

  • the user must go to the main menu;
  • Find the “main” subsection;
  • go down the page to the “reset” unit;
  • Select the sub-item “disable network”;
  • to confirm the changes, the previous value must be pressed again.

After getting approval, the system will reboot the hardware.

iOS 13 system update

Errors in the operating system also affect the functionality of the wireless module. The problem is not found on all devices running on this OS and appears in different types:

  • Denial of Internet distribution;
  • Regular attempts to disconnect from the connection;
  • Other gadgets refuse to detect the access point.

The problems can appear one by one or simultaneously. The above violations are the answer to the question of why I can’t share Wi-Fi from my iPhone to my home laptop. Only complete system update will solve the problem.

Wi-Fi Greyed Out On iPhone? Here’s The Fix.

  • Open Settings on your iPhone and select Modem Mode.
  • Click on the Wi-Fi password field. The name of the Wi-Fi network that your iPhone will create will be listed here.
  • Enter your password of choice in the Password field. It must contain at least 8 characters. Select Finish entering it, then select Done.

All iPhone 12 models have a personal 5 GHz Wi-Fi hotspot enabled by default. There is a new “Maximum Compatibility” switch in the “Settings” “Personal Hotspot” menu of these devices, which, when enabled, restores 2.4 GHz Wi-Fi to the personal hotspot.

  • Go to “Cellular data network”.
  • Scroll down and under “Modem Mode” delete everything that is written there and write it again (Each cellular provider has its own network details, you can find them on your provider’s website).
  • Go to Settings on your iPhone and select Modem Mode.
  • Click on the Wi-Fi Password field. This will also be the name of the Wi-Fi network that the iPhone will create.
  • Enter the desired password in the Password field. It must be at least 8 characters long. When you are done, select Done.

What to do when you lose Modem Mode on your iPhone? [Instruction]

Recently I was approached by a nice lady (Katya) with a request to help her with her problem. The thing is that after updating to iOS 8, on her iPhone 5S from the Settings section completely disappeared modem mode.

This is not the first time and I have personally experienced this before. There is nothing wrong with it and it’s quite easy to fix this unfairness. Today I’m going to share with you my plan of action that will help bring back the missing Modem Mode item on your iPhone.

receive, internet, access, iphone

Apple’s support site says roughly the following: “The availability of the iPhone Modem Mode feature depends solely on whether or not your carrier supports this feature.”.

Maybe the bourgeoisie does, but in the CIS countries, as always, they have their own “laws of physics”. In any case, this page lists a number of carriers (and countries where they are present) that support Personal Hotspot.

In order to get the missing Modem Mode option back on your iPhone, follow the plan below:

STEP 1. On your iOS device, go to Settings Cellular Communication Cellular Data Network.

STEP 2. Scroll down to the MODEM MODE section and enter the word internet in the APN field.

STEP 3. Now go back to Settings and, hopefully, see the item Modem Mode appeared (if the miracle did not happen, just reboot the iPhone, and then check Settings again).

The method described above works in 90% of cases. If you fall into the 10% of “lucky” people, try the following:

  • Hard reset of the iPhone (simultaneous pressing of the POWER and HOME buttons)
  • Reset network settings to Settings General Reset network settings

There were cases when people asked “And I have a Modem Mode item is not active and highlighted in gray. I Can’t Press It. What to do?”.

In this case you simply need to go into the Cellular Settings and activate the slider next to Cellular Data.

In general, the Modem Mode function is very unpredictable. I wrote more about Personal Hotspot Connection earlier in a separate article. Sometimes it happens that there is no way to make it work.

It happens that you connect to the access point, and after a couple of seconds the connection is disconnected, and so on and so forth.

And sometimes the phone and computer seem to be connected, but the Internet on the computer was not and is not.
