Question 1: My mobile phone is connected with a wireless network card. What happened? Please confirm that when you are connected to WLAN, other devices can access the Internet through this WLAN network. I suggest you do this: 1. Turn on the wireless signal of the wireless router to ensure the normal network function of the router. The router connection password should be set to 8 digits or more. 2. If you used to be able to connect to other wireless devices normally, but now the wireless devices can't connect, I suggest you click on the previous wireless devices, select "Forget", then search for new wireless devices and re-enter the password to connect. 3. Check whether the wireless router has turned on the wireless broadcast function and whether the router is set to hide. Confirm whether the device supports the signal sent by the router. 4. Check and confirm whether the router settings are correct according to the router manual, or contact the router customer service. 5. Check whether the wireless router settings and DHCP functions are enabled. 6. Set the static IP address of the device. 7. Restart the device and restart the router. 8. Connect the router to other devices to see if it is normal, or try to replace another router.

Question 2: What about the network card on the mobile phone? Five points. This requires you to try to brush your mobile phone. If the mobile phone has a large space, there are not many programs running.

Question 3: What should I do if there is something wrong with the mobile phone network? The first method is to look at your mobile phone information and see if you bought a parallel brush machine to find customer service.

The second method (but I added some mobile phone software to my mobile phone when I went home) What software did you add to this sentence?

The third method is that you sell your mobile phone to help you add some needed software, such as QQ UC, and don't add software when surfing the Internet.

You will get extra points if you play so hard.

Question 4: The mobile phone network can't be used. What shall we do? As we know, domestic smart phone network operators mainly include China Mobile, China Unicom and China Telecom, and different network operators have different methods to build their mobile networks. If it is confirmed that mobile traffic is turned on on the mobile phone, the mobile phone is not in arrears, but it is still unable to access the Internet, mostly because there is something wrong with the mobile phone network settings. The most direct way is to set the following mobile phone network settings. You can surf the Internet according to the settings of different network operators.

See: /...8 for details.

Question 5: What if the mobile phone always automatically connects to the network? If you don't give points if you answer correctly, then I wish your mobile phone (no matter you change the brand of shrimp) will always be automatically connected to the internet!

Have you set the automatic calibration of the mobile phone to update the network time? It's like the time calibration service in WINDOWS is starving, so you will often see the Internet tips of mobile phones. As a result, you searched all the mobile phone programs and couldn't find out which damn shanzhai program was secretly surfing the Internet ... In fact, don't worry, there is not much loss to your traffic (if you have a monthly subscription). ...

Question 6: What's wrong with the mobile phone showing no network service? There are many reasons why mobile phones don't have network service. No signal is one of them. It may also lead to poor contact between the SIM card and the card slot. Cell phones can also cause call forwarding. So, you can put someone else's card on your mobile phone, or you can put your card on someone else's mobile phone. With this method, you can judge whether there is something wrong with your card or your mobile phone, so as to prescribe the right medicine. I wish you success!

Question 7: What should I do if the mobile phone network is unstable?

Smartphones can be repaired or built with the help of third-party software.

Setting method: enter the menu → Tools → Settings → Connection Settings → Access Point → Options → Add Access Point → Use the default settings → Connection name: UC 1 (or 2 or 3 or 4 or 5, because you will see five groups of parameters below) → Access point name: CMWAP→ Options → Advanced Settings → Mobile IP address (see the following five groups of parameters (continued) → That's it. I suggest you set up more groups, so if you find that the speed is slow, you can change to others. The parameters are listed below for everyone to share. Parameters:

Mobile phone IP address1:10.125.79.129 port: 2992.

Mobile IP address 2:10.28.138.136 Port: 54832.

Mobile IP address 3: 10.38. 138+036 Port: 54832 Mobile IP address 4: 211.15.9 Port: 80.

Mobile phone IP address 5:10.210.231.213 port: 920 1.

Another possibility is that the network is unstable and your current network environment is not good. You can find the icon of the network in the progress bar (next to the time), and right-click the steps to diagnose and repair it. There is a good base station locking software, you can try it.

The above can solve your past problems.

Question 8: I want to buy a mobile phone, but what kind of mobile phone network is it? China Mobile, China Unicom and China Telecom have different network frequency bands. Simply put, just like they are walking on their own highways, these highways are interconnected at some point, and you can make telecommunication calls by mobile phone. Mobile uses GSM network, which is the most mature network with the largest number of users, and it is also a network with high transmission power and the largest radiation arc because of frequency band problems (detailed reasons will not be mentioned, Baidu will talk about it); CDMA2000 of telecom was originally used by the US military, so it is also called the greenest and safest network. Unicom's WCDMA network is the most promising network.

Therefore, a mobile card must have a mobile phone that supports GSM network. Some mobile phones are dual-mode, that is, they can support at least two mobile phone cards, namely China Mobile, China Telecom and China Unicom. Please consult the sales staff when buying a mobile phone. I suggest asking clearly, because some mobile phones are dual-mode, but only support mobile 2G services, even if you make a phone call, you can't use mobile 3G.

Question 9: What if the computer has a network and the mobile phone has no network? 1. Is the router a wireless router? If yes, continue to the next one;

2. Can the mobile phone search for WIFI? If not, check whether the WIFI function in the router is turned off. If yes, continue to the next item;

3. You can search for WIFI, but you can't connect. Check whether the DHCP function in the router is turned on. If yes, continue to the next item;

4. Manually configure the IP address for the mobile phone, and match "192. 168.0.2~99" or "192./68.1.2 ~ 99" according to the gateway address on the back of the router.

5. Finally, set the password of WIFI in the router.

Pure hand tour, hope to adopt. If you have any questions, you can email me [email protection]

Question 10: What's wrong with the connection of mobile phone network data? Common problems of many mobile phones, especially Android phones. Apple phones will also appear.

Generally, it is a system problem, which belongs to the "normal" phenomenon.

Generally, it can be solved by restarting. Or turn on the flight mode and then turn it off.
