Why is my Samsung i9300 wireless old and dropped? Ask for an answer from a master

Android phone WLAN can't connect to the wireless router, prompt"Deactivated, protected by WPA WPA2 PSK"Solution: There is a wireless router at home, two laptops, and an Android phone, and after setting it up, it is found that one of them will go wireless, and one laptop cannot access the Internet wirelessly, and the mobile phone cannot go wireless, and connect to WLAN (the network of the wireless router) with WiFi, and it keeps showing "Obtaining IP address" or "Deactivated, protected by WPA WPA2 PSK". After some research, it was found that the reason for compatibility, WPA2 and other cryptographic technologies are more advanced and not easy to solve, but they are incompatible with some devices or the device does not support more than 8-digit passwords, there are three solutions:

1. Not recommended method: enter the wireless router (I don't know how to read the manual or search for it), change the wireless network security password to a lower "wep" or turn off the wireless security option, so that the settings can be restarted.

2. Change the psk password (the password of the wireless router wpa-psk wpa2-psk) to 8 digits, for example: apk3apk3, save it, and restart it.

1.If your phone is old and disconnected when your computer is on, then you can rule out the problem that there is a problem with the router settings, and it may be a signal problem with the router itself.

2.If your computer won't turn on and turns off, it means that you haven't set up your router and should reset it and reset it.

3.Take your phone to another place with a wireless network to see if it drops, if this is the case, it means that there is a problem with your phone's wireless device, and it is best to take it to Samsung after-sales service to test it.

The most likely is a temporary system failure, and you need to reset the router options. Here's how:

Log in to the router management address based on the information on the back of the wireless router (including the router IP address, login username and password).

In the router management interface, switch to the "Wireless Settings" tab and click the "Wireless Encryption" item, where you can set the "Safe Mode".

Click on the "Safe Mode" drop-down list and select the "WPA2-PSK" item from its extended list, which is a secure encryption mode that all phones support.

Click the "OK" button to save the settings. Finally, switch to the "System Tools" tab and click the "Restart Router" button to restart the router.

Finally, you can try to use your mobile phone to connect to the wifi hotspot, if the fault still exists, it is recommended to change to other "safe mode" type to try to solve it.

If the Samsung i9300WiFi signal is weak or unstable and causes frequent drops, it is recommended:

1.Check if other devices have a good or full signal to connect to the wireless network.

2.Check to see if there are many devices connected to the wireless network.

4.If it is a home router, it is recommended to disconnect the power supply for a while and try to plug it in again.

5.If you are using the network operator's wireless network, it is recommended to try a different location.

6.Try a different wireless network.

7.Back up the data in the machine (e.g., contacts, text messages, multi**, etc.), and then restore the factory settings (Settings - Reset Privacy - Factory Reset).

If the problem persists after the above operation, please bring the purchase invoice, warranty card and machine to the Samsung service center for inspection.

There are generally three situations when a Samsung phone is disconnected:

1.Strong interference from radio waves can cause dropouts. Since mobile communication is propagated by air waves, when some air waves interfere with the radio waves being used to a certain extent, the use of signal noise ratio drops below the standard value, and the mobile phone will automatically turn off, and the connection will appear.

2.Transmission is blocked, reflections from buildings, and interference with radio waves at the receiving point can also cause dropouts.

3.If the cross-area handover fails to be dropped, the voice channel of the user's call needs to be switched from the original cell to the new service cell, but the user of the new service cell is also random, if there is no effective audio channel available during the switching, the cross-zone handover will fail, causing the mobile phone to drop. If the call is suddenly dropped, you can move it to change the position and try to avoid using it in the blind spot.

Hello: According to your description, the situation may be a wireless network signal problem, and it is recommended that you try to operate your phone as follows:

1. Go to Settings - Wireless & Network - WLAN settings, press and hold the name of the network you want to connect to, select Forget Network or Delete Network and reconnect.

2. Restart your phone and router.

3. If the problem persists, try to replace it with another wireless network.

4. It may also be that there is a conflict of IPs, and the route of Internet access is changed to dynamic. Change the IP addresses of other devices to automatically obtain them, and enable DHCP for routes.

5. Back up your phone data (**book, SMS, multi** files, etc.), and restore factory settings (settings-reset-factory reset).

There are two main reasons for this problem:

1. The wife signal source is far away, which leads to unstable signal 2. There are certain problems with the wife function of the mobile phone itself.

Solution: 1. Move to a place close to the signal source, or change to a router with higher emission intensity (the radiation will also increase).

2. Replace the hardware of the mobile phone, but it is recommended to buy a new one: it is very likely to be caused by being too far away from the transmitter, the general mobile phone wife function is normal, you can conduct a simple test, such as standing on the edge of the wife transmitter source, open the wife to observe whether it will be dropped, or change a mobile phone to stand in the same place for testing, provided that the configuration is the same.

It's a normal problem,S3 was 4999 when it first came out, and now it's only 3000+,My S3 is often not connected,To be precise, the system is not responding,This is a problem with the receiver,Go to the service desk to change one。

In the first step, the phone dials* to enter the debugging mode.

The second step is to click the menu button, select the wifi item, and enter the wifi debugging menu.

In the third part, click "Open" in the middle to turn it into "Close".

Just exit debug mode and you're done.

Possible reasons and solutions for Samsung i9300 mobile phone not connecting to wifi network:

1.First of all, check whether the wireless router is working normally, you can use other mobile phones or digital products to connect to the wifi signal, if you can connect and surf the Internet normally, then generally this router can work normally.

2.The phone is turned on to sleep and the network is turned off.

Check whether the phone has the option to turn off the network in the dormant state, the phone will be disconnected after a period of time or cannot receive the background chat software, the possible reason is that the phone is turned on the function of turning off the network by mistake.

3.If you use the router for a long time, the router may freeze its death. Just restart your wireless router.

4.The type of certification is not suitable. Try to change the authentication type of the router, it is better to choose the secure "WPA2-PSK" type mode, and the following encryption algorithm is better to choose "AES".

5.The network settings of the mobile phone or router are abnormal. Consider restoring your router factory settings and cellular network settings.
