iphone4 internet problem!! There is wifi and no internet access!! Kneel and beg for !!

It's your router that is most likely to be caused by encryption.

If you don't know how to set the static address of the iphone4, don't choose the router's WPA PSK or WPA2 PSKWPA or WPA PSK+WPA2 PSK encryption You only need to set it to WEP Normal encryption mode If your router can choose 1, 2, 3 or more password fields, you must choose the first password field Generally, as I said, it can be solved!!

You have said that you need to dial up to access the Internet when you connect to the laptop, which means that your iPhone is only connected to the LAN when connected to wireless, and it must not be able to access the Internet. You log in, find the WAN settings in it, select PPPoe, fill in the broadband username and password, and save and log out. Delete the dialer on your computer.

In this way, your router will automatically dial up, every time you connect to the wireless network, you can go online, the computer does not need to open the dial every time, and your iphone can connect to the wireless network to access the Internet.

Hope it helps!

Yes your IP4 does not have dial-up function, I suggest you buy a WR700N mini router to set up simple and plug and play.

I had the same problems as you before.

No. You turn on the wifi, click the blue right arrow there, see if the subnet mask has anything, if you don't turn off the wireless network, wait for 1 minute and then connect, if it doesn't work, manually hit the IP

No, you can see in your IP4 network settings that you may need to set a static IP.

Is CMCC your own home wireless network? It could be an issue with the encryption method.

Because you are using a custom router from China Unicom, the manufacturer has restricted the wireless and extra ports when it leaves the factory, and only allows one port to be used for Internet access. If you want to turn on wifi and other ports, you need to reset it:

1. Access the router super administrator management address (note: not the router user management address) 2. Enter the super administrator account: This is different because of different regions, so it is recommended to consult the gateway manufacturer.

3. Click Basic Configuration.

This configuration. 4. You can create a new WAN connection or modify an existing default WAN connection. Select Mode as: route.

Check "PPPoE" and its first sub-option "Do not enable PPPoE ** or PPPoE Route Bridge Mixed Mode" (if this option is not available, you should first select the option "Service Mode:" as "intern" at the bottom of the page).

Open the browser and enter it in the address bar or look at the manual of your route, the password and account manual for login have the default password and account number.

Go to the router settings interface and find the security settings and there will be a wifi password setting.

Generally, as long as you have wired and can use wifi, there is no problem, the so-called setting of this route is just to go in and choose the encryption method and set the wifi account and password. Determine whether your cable can access the Internet first...

1. Connect to wifi

Reconnect to wifi. Press "Settings ->Wi-Fi" in your iPhone 5s, and confirm that you have Wi-Fi enabled and are connected to Wi-Fi in this interface. If it's off, you need to turn Wi-Fi on, choose a wireless network, and connect to that network.

2. Check the signal.

In the status bar you can see the signal strength of your Wi-Fi network (the more cells you have, the stronger the signal), and if the signal is weak or you can't connect to the network, you need to:

1.Hold your iPhone5S device close to the wireless network transmitter (wireless LAN access point or router);

2.Avoid some devices that affect the wireless LAN signal, such as microwave ovens, concrete walls, etc.;

3.Reopen your browser to see if you are connected to the Internet and can surf the Internet.

3. Verify the password.

Some wireless networks require a password to join, and password-protected Wi-Fi networks have a lock icon, so if you can't connect to Wi-Fi, do the following:

1.Verify that the password is not incorrect, re-type the password or change the password;

2.Restart Wi-Fi and re-enter your password.

4. Reset network settings.

To reset network settings, locate the "Settings -> General" interface in your iPhone5S, then swipe the screen to scroll down and select "Reset -> Reset Network Settings". Then restart your device, reconnect to the wireless wifi after rebooting, and see if you can surf the Internet.

5DNS failure.

Maybe you use your computer to share Wi-Fi, so it is possible that your phone is connected to Wi-Fi, but you can't access the Internet.

Restart your phone and try again.

iPhone4 can connect to Wi-Fi, but it can't, you can set it up by doing the following:

a) Mobile phone problems.

1. Open the iPhone settings function, then enter the wireless wifi that has been connected but cannot go online, turn off the wireless wifi first and then turn it on.

2. Also enter the window that has been connected to wifi, then click the small arrow behind to come to the wifi information interface, click ignore this network and confirm to ignore, ignore and then choose to rejoin the wireless wifi you just want to access in the settings, fill in the password to join.

b) The router is not set up correctly.

1.Turn on the power supply, then plug in the network cable, plug the incoming cable into the blue port, and then plug in a blue port for the network cable connected to the computer. After doing these jobs, you will see that there is an address and account password behind the router, and after connecting, enter the address you see on the router in the browser.

2.Then enter, enter the corresponding account and password.

3.After entering the operation interface, you will see a setup wizard on the left, and you will enter (generally pop up automatically).

4.Click Next, enter the Internet access method settings, you can see that there are three Internet access options, if it is dial-up, then use PPPoE. Dynamic IP can be used by plugging the computer directly into the network, and there is a DHCP server on the upper layer.

The static IP is generally a private line or something, or it may be a cell bandwidth, etc., and the upper layer does not have a DHCP server, or wants to fix the IP. As I dial up, I choose PPPoE.

5.If you choose PPPOE dial-up Internet access, you need to fill in the Internet account number and password, and you will have an account number and password when you open broadband, and you can fill it in.

6.Then the next step is to go to the wireless setup. You can see the channel, mode, security options, SSID, etc., generally SSID is a name, you can fill in at will, and then the mode mostly uses 11BGN

The wireless security option to choose WPA-PSK WPA2-PSK is so secure.

Try restoring your network settings and reconnecting to your wireless.

The IP address is not in the same number segment as the company.

I can't think of anything other than a reboot.

Could it be that a static IP is used, or else?

First of all, I often have this situation in my family, solution 1: check whether the network cable is plugged in; 2: Restart the router, maybe the router is dead; 3：

It's really not good to call the broadband there, let them refresh in the background; 4: If it doesn't work, you can only call ** to broadband and let them make an appointment with an engineer to overhaul Good luck.

I've encountered it before, TP router, I don't know what route you are, probably the situation is that the host can access the Internet after connecting to the network, the laptop can go to the wifi Internet, that is, the mobile phone finds the wifi link but can't open the web page.

The router is not set correctly,It seems to be a stream** or what option,There's a "hook",Just remove that hook,But it seems that after removing it, the TV can't watch network TV or something,I don't remember the specific operation clearly,It's been too long,The route has also changed。

This should be a problem with the phone's settings.

Telecom cards can only be used with telecom mobile phones.

1. If the opportunity allows; Restart the wireless router; See if you can solve the problem.

2. In Make sure your phone is within the wireless network coverage range, click "Scan" to refresh the wireless network list.

3. Connect the computer to the router through the network cable and log in to the management interface of the router.

4. In Wireless Settings - Basic Settings, the channel is between 1 and 11, the wireless function is turned on, and the router is restarted.

2: What should I do if I search for a wireless signal and the connection is unsuccessful.

1. The unsuccessful wireless connection may be caused by incorrect settings of wireless password and other parameters. A new key entry attempt.

2. Please make sure that the wireless router does not have the wireless MAC address filtering function enabled; Wireless Settings - Wireless MAC address filtering, turn off the wireless MAC address filtering function Wireless Settings - Wireless MAC address filtering, turn off the wireless MAC address filtering function.

Three: What should I do if the wireless connection is successful and I can't open the web page?

First of all, check whether the router is connected to the external network, log in to the router management interface, and look at the running status - WAN port status, if it is 0, please follow the router quick setup guide to set it again.

2. If the computer can access the Internet, the mobile phone cannot; Check whether the SSID number of the wireless router is in Chinese; If it is changed to letters and numbers; Mobile phones sometimes can't effectively recognize Chinese:

3. If the above does not contain the absolute solution: we set a static IP for the mobile phone

4. The wireless router supports between 15-20 wireless devices; When the maximum number of connected wireless devices is exceeded, although Cong Town is connected to the wireless network; But you're wireless; At this time, you can unplug the wireless router; Turn on the wireless router after 10 minutes.

Sometimes, I don't know why this happens, a small exclamation mark is displayed at the wireless network, although it is connected, but it cannot access the Internet. How to deal with this situation? Why can't I connect to the Internet when I connect to the wifi?
