The Xiaomi Mi 2 phone receives an unstable router signal

1. The router will be prone to problems after being used old, although the signal is full, but there will also be a disconnection, because the computer and the mobile phone operating mechanism is different, the computer uses the window system, many software are relatively perfect, and the mobile phone is a Linux system-based Android, many software are in the initial stage, as long as it is interrupted, it will be disconnected immediately, and there will be no error correction, including the mobile phone for WLAN support accessor, so many mobile phones will appear in this situation.

2. As I said upstairs, the dormant state is turned on, which is an energy-saving state of the network card, even if the network card of the computer is also available, in fact, the network card of the mobile phone and the computer are also part of the same style, which is a relatively old technology, although the old but there will still be judgment errors, which can be turned off by setting.

3. In the event of sudden interference, because the current wifi is basically high frequency, the disadvantage of high frequency is that the signal is weak, and the advantage is that the anti-interference is good, but this anti-interference means that he can be completely free from interference, but his signal frequency is high, and the interference only affects part of his frequency vibration, but as I said before, the operation form of Linux is actually not perfect, so it is not surprising that it will lead to disconnection.

In fact, you can try to use a Linux system, such as the YLMF system, and a similar situation will occur, and if it is the third case, it will also appear on a general computer. This is normal.

Hi! According to the problem you described, it is recommended that you back up your important data first, and then enter Recovery to empty all data, and do not restore data temporarily after booting up, and see if it can solve the problem. (Backup:.)

Security Center - Backup, back up the data you need. Clear data: In the shutdown state, press and hold the volume plus button and the shutdown button, and let go when the boot screen appears, and you can enter recovery.

Go to Recovery >Chinese >> Clear Data >> Erase All Data).

A more detailed description of the problem will help netizens understand the troubles you are encountering and help you solve the problem more accurately. Thank you for supporting Xiaomi phones!

If it is wifi, it is recommended that you click Settings - WLAN - Advanced Settings to select Never sleep, and click Settings - WLAN - to find this WiFi, click the small arrow on the right, do not save the network, re-enter the password to try, or try to restart the router to try.

Sorry for the inconvenience caused to your use, as an operator we attach great importance to network construction, has been constantly strengthening the breadth and depth of network signal coverage, because network coverage will be affected by many factors, we will strive to speed up the pace of network construction, and constantly improve the network coverage area, look forward to your continued attention and supervision, thank you!

First, it may be a problem with the local operator.

Second, it may be a problem with the location of the mobile phone when using it.

Third, it may be a problem with the mobile phone itself.

The following is the Xiaomi mobile phone signal problem and how to solve it:

1. Problems with local operators.

When the operator is in the process of upgrading, optimization, maintenance, etc., the mobile phone signal will become very poor, which is because the operator needs to upgrade and maintain it once within a certain period of time in order to provide better services to customers. This is an irresistible factor.

Solution: Wait patiently for the operator's upgrade and maintenance to complete before restoring the normal mobile phone signal, which generally will not exceed one day, and the general upgrade and maintenance will be selected late at night, and try to use the mobile phone in the case of low peak.

Second, the problem of the location when using the mobile phone.

1. Signal blind spot: The blind spot of mobile phone signal refers to the area outside the coverage of the operator, including elevators, factories, remote suburbs, mountainous areas and places that have not yet been covered by wireless communication networks.

Solution: The blind spot of various indoor places such as conference rooms, hotels, basements, entertainment venues, and low-rise buildings can be appropriately expanded through tools.

2. Weak signal area: It refers to the geographical location can not receive the signal normally to cause the signal to be strong and weak, and the biggest difference with the signal blind area is that the weak area can communicate, but the call quality is not ideal, sometimes there may be a jam or disconnection, and the blind spot is directly unable to talk.

Solution: Try to go to some open places and places with high signal strength to make calls, which can effectively improve the call quality.

With the meter 3 for half a year, I have never felt the signal, there has been a comparison with 4s, on the highway a colleague's 4s speech ** heard clearly, and then borrowed my meter 3 dozen, it was very clear. If you say that the signal difference should be the poor signal of the Xiaomi system of other mobile phones, indeed, I have tried to use LG LU6200 to flash MIUI V4, and there will often be no service, which is probably the reason for MIUI, MIUI is not compatible with all mobile phones.

I didn't find this, I have used every Xiaomi mobile phone. It feels stable all the time and the signal is strong!

Do you add shells, some shells do have an impact on the network signal.

The reason for the bad signal is that the signal will be affected by various factors such as terrain, landform, and high-rise buildings in the process of propagation

1. Turn the phone on and off again;

2. Swap the SIM card to a family member's or friend's phone and try again;

3. Check whether there is a signal from other Unicom users around;

If the above situation has not been resolved, it is recommended to contact the manual customer service of the place where you belong for processing.

Hello landlord, is this problem on your mobile phone a recent one? The slow Internet speed of the mobile phone may be caused by the poor signal reception of the environment in which the mobile phone is located. There are several reasons for poor cell phone signal:

1. The network coverage of the environment where the mobile phone is located is not good (such as in high-rise buildings, mountainous areas, indoor steel structures, interference of large machinery and equipment, base station failure, etc.); 2. Caused by the loosening of the card insertion method or card slot; 3. The phone is running slowly due to too many programs running in the background or junk files accumulated in the phone's memory. According to the above reasons, you can clean up the background program with one click, reseat the ** card, and then try it in another place. If it still doesn't work, it is recommended to clear your phone's cache.

Operation steps: When the phone is turned off, press and hold the power button and the volume down button at the same time for about 10 seconds to enter the engineering mode (power button confirmation, volume plus or minus key selection), and select Clear Cache. Clearing your phone's cache can clean up the junk files accumulated in the memory, free up more memory space, and improve the running speed of your phone.

Try it. In addition, your mobile phone supports mobile 3G Internet access, you can use a mobile card, turn on 3G in the drop-down menu and experience 3G network to try.

Reasons and solutions for the poor Internet signal of the Xiaomi Mi 2 mobile phone:

1.See if it's in a dead zone. This kind of blind spot includes outside the network coverage area, such as workshops, factories, suburbs, rural areas and other places where network communication facilities have not yet been built, and places in the city where the mobile phone is blocked by shielding and the signal cannot be covered, such as in office buildings, bar rooms, elevators, underground places, buildings, etc.

Solution: Get out of the area and go to a wide area to call your mobile phone.

2.See if there are any interfering facilities. Since the mobile phone receives signals through the propagation of electromagnetic waves, the base station establishes a connection between the transmitted radio waves and the mobile phone, so as to achieve the purpose of voice call.

Therefore, the interference of electromagnetic waves can have a negative effect on mobile phones. This situation is common in the test room, and if the shield is not turned off after the test, it will cause disturbances in the surrounding area.

Solution: Find the surrounding signal interference tools and remove them.

3.Due to temporary network failures, or the network is particularly busy, it will also cause poor mobile phone signal. For example, in the bustling business district, there may also be a situation where the ** cannot be dialed out or called. There may also be delays during peak periods such as Chinese New Year's Eve.

Solution: Avoid downtown areas and peak areas, and the signal condition will naturally improve.

4.Other solutions:

a.Can react like a local mobile company, bLet a professional test the condition of the signal, cSwitching carriers can help, dReplace or repair your phone to see if it's a problem with your phoneBuy a cell phone signal booster.

Damn, isn't it, I'm still going to buy Xiaomi 2a to use it in Nigeria, and I'll forget it at a glance.

Whether the SIM card is inserted correctly.

Whether the wrong SIM card is inserted, such as the standard version inserts the telecom SIM card, etc.

Go to Hardware Detection to see if the SIM card is working properly (enter * * on the dial screen). If the SIM status is normal, go to step 5, or if the status is unknown, go to step 4.

Try to replace a different SIM card, if the status is still unknown during hardware testing, it is recommended to go to the repair point for testing; If the detection status is normal, it is recommended to go to the carrier to replace a SIM card (the SIM card may be aging).

Whether the network type is correct and whether the carrier selects Automatic. (China Unicom selects 3G priority, mobile selects only 2G, and China Telecom selects automatic).

If the network type of the non-telecom mobile phone is CDMA automatic, you need to change the network type to "wcdmapreferred" in the mobile phone information (**) to solve the problem.

Whether there is no signal in the area. You need to check whether other mobile phones on the same network have signals.

Back up your data, flash to the latest system version and try again.

If the above methods still do not help you solve the problem, go to a nearby repair point for repair and inspection.

There are two possibilities for this, one is the hardware, which usually needs to be repaired, and the other is the software, you can update the system to the latest version or brush other versions to try it. If you can't flash the machine, you can only go to a nearby maintenance point to check it.

Xiaomi has the function of flashing the phone,Select the system upgrade in the settings about the phone,Brush to the latest system to try。

Please ask if your card is a 3G card, it is recommended to adjust the phone to 2G 3G compatibility mode.

It may be a software problem or a signal receiving module problem, try flashing the machine first.

1. The mobile phone is connected to wifi, which means that the signal sent by the router is received by the mobile phone normally, but it is not necessary to be able to access the Internet, and the network signal transmitted by the broadband can only be accessed normally.

2. This situation may be caused by the router hanging, or it may be caused by the unstable broadband network signal. The former turns off the router for 10 seconds and then restarts the test. The latter checks whether the broadband signal is normal.

Formatted,Don't flash again.,Thank you.。
