Please help me look at the WIFI problem of my mobile phone

Pull down the status bar above, click on the wifi icon If a box comes out, there are a bunch of names of the wifi you have been on, and you should often be on the wifi at home, so find the name of your wifi and click on it, and then click on the connection, if you are asked to write out the password, you will do it.

There may be a bad wifi signal in your place, so the connection is unstable. Generally, you only need to enter the password in the place where you can find the wifi signal, if it becomes a question mark for a while, it means that the signal connection between your mobile phone and the wifi hotspot is broken, generally when there is a signal, the mobile phone will automatically connect.

Whether you're using a mobile WiFi hotspot (name cmcc, cmcc-edu, cmcc-auto), if so, that's two things to say. Mobile wifi needs a signal at least greater than 4 bars to connect, and now mobile wifi even in big cities (except Beijing), the coverage area is not very wide, even if there is a signal, it can only be connected when the signal is very good, and even if it is connected, it is often disconnected, so mobile wifi is basically useless now (the future prospects are infinitely bright).

As for the traffic data you said, it's okay, just because the GPRS signal and TP signal have a wide coverage (about kilometers, wifi is only about 100m, and it is also in an open area, about 10-20m in the city), wifi and gprs are both fidelity wireless signals, but their types are different. The wifi coverage area is small, but ** cheap and the maintenance costs are cheap (which is why the wifi signal costs by the hour); GPRS, TP, WCDMA and other types of base stations have high cost and high maintenance costs (the base station only covers kilometers, it will cost 500,000, about 10,000 a month, and it is not considered labor. So the flow rate is calculated by m, not by length)

If you still have questions, please ask.

The reasons why the mobile phone is connected to the wifi but cannot access the Internet are: 1. The wifi itself is a problem, and the wifi may not be connected normally, resulting in the inability to access the Internet. 2. Router problems, the router may be overheated or damaged.

3. Broadband arrears may lead to inability to access the Internet. 4. The wifi name contains Chinese, resulting in some mobile phones unable to connect to the Internet. 5. There may be a problem with the mobile phone system, which may cause the connection to wifi but the Internet cannot be accessed.

Suggested solutions: 1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet and eliminate the problem of wifi itself. 2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet.

3. Contact broadband customer service to confirm whether there is any abnormality in the broadband, such as arrears, recharge the broadband, and then dial up the connection. 4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting. 5. If the above reasons are ruled out, it is likely to be a problem with the mobile phone system for a long time, it is recommended to restore the factory settings or flash the phone to see if it can solve the problem.

1: The wifi function is equivalent to connecting your mobile phone and router with a network cable. WiFi is that cable! After connecting, the mobile phone can access the Internet through WiFi. And the wireless Internet function of the laptop is wifi!

2: If you understand the principle of the first wifi, you should be able to understand. The function of wifi is not the function of the data cable, so the laptop cannot be connected to the mobile phone through wifi to access the Internet. You can only connect your phone with a data cable and then connect to the GPRS network.

Click here for information! There are surprises!

1: Yes, that's something like that

2: Well, I've studied this before, but it's not feasible!! It's just that it's slow when surfing the Internet like that!! But there is software for this!!

Because the wireless reception ability of the mobile phone is weak, it is basically impossible to go out of the room. So the recommendations are as follows:

Connect the line to the room on the first floor where you use your mobile phone, and connect the line directly to the wireless router, and set it up on the wireless router, so that the problem of your mobile phone Internet access can be solved.

Take TP-Link as an example, follow the TP-Link manual to start the setup, and take the XP system as an example.

Connect the tp-link to the power supply, turn on the computer, and type tp-link **( in the browser

After opening, enter the username and password (password) of your home broadband as prompted, and then set a security password, after success, turn off TP-link, plug in the power again, and connect your home broadband to OK.

Open the settings on your phone, select My WLAN will automatically scan, click on WLAN settings to find a locked TP-Link ** account, click to enter the security password you set, and you can connect it.

If your laptop has wireless, it must be no problem to use it downstairs, and it is no problem to use it upstairs if you can receive a signal.

Second, if the upstairs laptop can't receive the wireless, just pull a cable to route from the wireless to the notebook.

The Smartphone Player Alliance has you covered."

Buy an unlimited router directly, you can spend dozens of dollars, and after setting it up, the laptop and mobile phone don't need to connect to the network cable to go online, which is very convenient.

Buy a wireless router Connect from the wired router on the second floor to the first floor and connect to the wireless router so that you have a wireless signal on the first floor. If it is placed on the second floor, the wireless signal is too weak, and it is difficult to receive it on the first floor.

Just replace the wired router with a wireless one.

With wireless line, mobile phones and laptops can be used

Buy a three-antenna with strong functions, and it is recommended that TP-Link have three antennas, and I use it well.

Wireless network includes wifi, 3G and 2G (GPRS), generally directly said wireless network is only wifi, to explain the 3G or 2G wireless network, as long as it is not explained is wifi, as for your question to write wireless network and wifi is a function;

Cellular data is from the transmission to the exchange of data are grouped technology, the user is equipped with a wireless packet modem, through a special packet base station into the packet network, can access the host on the packet network, database, can also call another mobile data terminal. This technology is mainly used in specialized mobile data communication systems and can only provide mobile data users with a connection to a user of a packet-switched data network.

Generally, cellular data is the Internet transmission mode of mobile terminals, that is, Internet traffic
