Lenovo tablet a2109 how to surf the Internet, no network cable, no router 20

Get a wireless router and use wifi to access the Internet.

If you need to access the Internet, A2109 needs to be covered by wireless network around you, and log in with the corresponding password.

If you are connected to home broadband, and use a wireless router at the same time, set up the wireless and password in the wireless router settings menu (it needs to be English characters, the password is more than 8 digits, you can refer to the wireless router manual), after setting up the wireless router, enter the device menu: "Open "Settings" -- click the "WLAN" switch to turn on the wireless function, click "WLAN" Select the name of the wireless network that needs to be connected in the scan list that appears, click Connect, enter the password, and OK.

If you are connected to a public network (such as a public network such as CMCC or Chinanet), or in scenarios such as McDonald's or airports, you need to obtain an additional username or authentication code to access the website.

If you have any doubts about the product functions and software use in the future, it is recommended that you go to the Lenovo community (to ask questions, your questions will be followed and replied by other netizens or official personnel, thank you.)

I hope the above reply is helpful to you and I wish you a happy life!

If you have other wireless networks around you, try to compare:

a. Other networks can be connected normally, you can judge that the mobile phone system and key file hardware function is normal, you can try it as follows:

1. Wireless network availability: It is recommended to connect to the wireless network with other devices, compare whether it can be connected to the Internet normally, if it cannot be connected normally, it is recommended to re-set the wireless network, such as changing the channel, encryption mode, etc.;

2. Whether dial-up is required: some telecom network users use ADSL to access the Internet, and need to dial up to verify their identity through PPPoE, and the mobile device cannot be verified, so it cannot be connected to the Internet, and you can contact Telecom customer service (Telecom customer service**: 10000) for further consultation;

3. Number of wireless network connections: It is possible that there are too many users using the current network connection, resulting in the inability to use the network normally, so it is recommended to try it during idle periods;

4. Wireless network signal: When the wireless signal signal is weak, it may lead to the inability to connect normally or the application cannot be connected to the network normally, it is recommended to move the mobile device to a strong wireless network signal to try;

5. Wireless network restrictions: Some network service providers or network departments will restrict the use of wireless networks, such as binding the MAC address of the device that can be used, and it is recommended to check with the corresponding network service provider or management personnel;

6. Wireless network in public places: If you access the wireless network provided by the merchant or the operator, you may need to verify additional user name or authentication code and other information, usually after successful connection, you can open the browser and enter the corresponding user name and password to use it normally, it is recommended to consult the customer service of the merchant and the operator for specific situations;

7. If the above suggestions still cannot be improved, it is not excluded that the compatibility between the routing equipment and the product is caused, and it is recommended to change the wireless network or routing equipment to use;

b. If other network connections are also chaotic and cannot be used normally, it may be caused by abnormal system or hardware functions

1. Back up the fuselage data and try to restore factory settings;

2. If it still cannot be improved after recovery, take the time to go to the local maintenance site to test and process the system and hardware.

If the conditions are limited and it is not possible to compare with other wireless networks, it is recommended to conduct a simple investigation based on the above suggestions, and if it cannot be improved, send it to the repair site in time.

1. I've tried it above but it's useless.

2. If the wireless router wifi network at home can be used on the laptop, imported brand mobile phones, ipads, etc., it means that the telecom does not restrict you from using the router to share the Internet.

3. However, if the domestic tablet (including Lenovo) and the domestic mobile phone can be quickly connected in other places, but cannot be connected at home, it means that the compatibility problem of this router to this kind of tablet and mobile phone can be solved by resetting and resetting the wireless router.

4. If it is invalid by resetting, you can only replace the wireless router.

After many checks: I went through many experiments in different environments and combinations, and finally reluctantly abandoned the original road and set it up with a new route, and the tablet connection was successful.

Is the name of your wireless network in Chinese?

If it's changed to English letters, it's fine.

1. Check if the mobile phone has accidentally turned off the switch of data connection (System Settings - Wireless and Network - Data Connection).

2. Check whether you use some traffic monitoring software, such as setting a daily limit for traffic.

3. Try using the other options in System Settings - Wireless & Networks - Mobile Networks - Access Points.

4. If it still doesn't work, it is recommended to back up the data in the phone, restore the phone to factory settings, or go to a nearby Lenovo repair site to check the specific reason.

Dear Lenovo mobile phone users, hello!

Based on the description, it is recommended that you try to confirm if there is an exception that was caused by something in the past.

If you delete and modify the relevant programs or files of the system due to flashing the third-party firmware or root to obtain permissions, then it cannot be solved by restoring the factory settings of the phone, and you need to re-flash the phone to restore the use of the system.

Troubleshoot the system, which may be due to the abnormal wifi and Bluetooth services caused by the relevant modules on the hardware motherboard.

It is recommended that you take the time to go to the local Lenovo after-sales service center and let the engineer help detect and solve the problem, and you can log in to the official website to inquire about the address.
