You can try it, if it doesn't work, you can consult me again. I'm the First Lord, my answer.

Unlimited LAN (NB) = Wi-Fi (non-BNM) These two are actually the same thing.

If the wifi shows none, there is no signal available nearby.

Local area network, just for computers. LAN games such as CS. A mobile phone, that's still a mobile phone.

It's still not as good as a computer, if the school has a network, but there must be a wireless router to have, and it's within your search range, if the router is not good, the signal is also poor across the wall, just like KFC, hotels and those places They all have routers, and there is wifi out.

I've tried it too, it should be a router setup issue.

Open and open the wireless settings password is admin, turn on the wireless settings and SSID broadcast are selected, and then restart the router and try it.

Wireless setup issues Go to the forums to find posts about wifi.

Possible reasons and solutions for Apple mobile phone not connecting to wifi network:

1.First of all, check whether the wireless router is working normally, you can use other mobile phones or digital products to connect to the wifi signal, if you can connect and surf the Internet normally, then generally this router can work normally.

2.The phone is turned on to sleep and the network is turned off.

Check whether the phone has the option to turn off the network in the dormant state, the phone will be disconnected after a period of time or cannot receive the background chat software, the possible reason is that the phone is turned on the function of turning off the network by mistake.

3.If you use the router for a long time, the router may freeze its death. Just restart your wireless router.

4.The type of certification is not suitable. Try to change the authentication type of the router, it is better to choose the secure "WPA2-PSK" type mode, and the following encryption algorithm is better to choose "AES".

5.The network settings of the mobile phone or router are abnormal. Consider restoring your router factory settings and cellular network settings.

I've had this happen a few times, and the result of the final check was.

1.** line damage (you replace the ** line used for routing and ** used to play ** to see if it is damaged) 2If you have a problem with the network company, call ** to consult, see if there is a problem with the network here in your home, and confirm that the password on your mobile phone is entered correctly.

Try restarting your wireless router and if there is no switch on the machine, turn off the power for 2 minutes and then power it on.

Try factory resetting your cellular network settings.

Loven's approach works!! I'm also connected, and I'm having the same problem as you!! Adopt loven.

Click Settings - Select Network - DHCP - Renew Lease.

1. Select the AP wireless router.

Go to Settings - > WiFi, the iPhone will automatically search for visible access points in the area, each entry of which represents an access point (a router), if the access point requires authentication, a lock mark will appear on the entry (you need to enter a password when joining, and you will go out of the fan without entering the password, but it only means that the network has the ability to surf the Internet, and you are not connected).

2. Use DHCP to automatically configure.

Click the AP wireless router you need to use once, a tick will appear on the left side of the AP, indicating the currently selected AP, by default, the iPhone will automatically select DHCP mode to try to connect, if the AP requires authentication, the password input window will pop up, enter the password on it. After success, a symbol appears in the upper left corner of the screen to indicate that the connection is successful, and the symbol will change with the signal strength.

3. Manual configuration.

If the AP is only used as a switch, you need to manually set the IP and other information, at this time, first click the AP you need to use (the tick appears on the left), and then click the symbol on the right side of the AP, you will enter the AP setting screen, click the static button, you can manually set each option of the connection on this screen, and click the WiFi Networks (Wi-Fi network) button to take effect after setting the relevant information.

4. Set up a hidden AP

Some AP wireless routers may not be allowed to be searched, in which case you can set it manually. Click to search for others "Other" under the router list, enter the exact name of the AP wireless router in the name name, then click Security, the authentication screen appears, select the specified authentication method, and then enter the authentication information as needed, and click the Other Networks button to return to the wifi menu after completion.

Is the router encrypted with WAP?

Little 4 seems to recognize only this.

Other formats seem to be able to connect for a while at first, but after a while, they can't go up.

First, you see if the cat is turned on, and the cat has a prompt that the wireless network is connected, but it can't be connected to the network. Second, you try turning off the cellular network.

Restart it and try it or turn off the wifi before connecting and try it.

This is usually caused by system instability, and the solution is as follows:

Method 1: Reset settings five times in a row, Settings - General - Cellular Network - Cellular Data Network - Reset Settings *5 - Restart.

Method 2: Shut down - connect the charger to restart automatically - check that the wifi repair is complete.

Method 3: Use iTunes to restore the firmware, i.e. reflash the firmware.

Method 4: Turn on the hot air of the hair dryer and blow it towards the right 1-2 cm of the back camera for 2-3 minutes - check the wifi or restart to check the wifi.

Is iOS before 7? If it is the 6* version, this is a common problem, and the upgrade can be broken.

In addition, the wireless module of the 4S is easy to break.

Just go home, in other words, a few brothers are either rich or expensive.
