What should I do if I find that there is only one bar of wireless network and the signal cannot be c

Find a connection to a place with a better signal.

Factors affecting the wireless network signal:

1. If there are multiple wireless devices in the wireless environment, there may be channel conflicts and wireless signal interference problems.

2. The space of the family is crowded and not open enough, and the wall in the room is the main obstacle. Since the wireless LAN uses the wireless microwave frequency band. The biggest feature of microwave is that it propagates in a nearly straight line and has a weak diffraction ability, so the wireless receiving device placed behind the obstacle will receive a very weak signal or no signal.

3. Physical obstacles. In addition to blocking the microwave wireless signal, it can also absorb the electromagnetic energy and generate a weak current to drain away, all, the largest obstacle of the wireless signal in the home environment is the floor slab with a steel mesh, and the signal in this direction has almost no possibility of penetration. To be able to penetrate, the signal is also very weak.

4. The working frequency band of the IEEE standard is, and many devices in the industry are also working in this frequency band, such as: Bluetooth devices, microwave ovens, refrigerators, cordless**, etc. If there is a strong magnetic field in the vicinity, then the wireless network will definitely be affected accordingly.

5. Strong signal interference sources such as radio transmission towers, welding machines, trams or high-voltage power transformers within 100 meters of wireless equipment may also cause great interference to wireless signals or equipment.

If the router is your own, you can pull a signal cable. Even if you say something to others, you can only leave the entry point, no way.

It can only mean that your wireless router does not cover that location, solution 1, mobile wireless router location 2, add a route to extend to the location of your poor network 3, change a high-power wireless router.

If you can't connect, you can't connect! Move your location and try to find a strong signal and connect again.

This may be because your device is connected to a wireless network, but you can't get internet access from that network. Here are some of the possible reasons for this problem:1

Your router may have been disconnected from the internet. You can try restarting your router and waiting for it to reconnect to the internet. 2.

Your device may not have obtained the IP address or DNS server correctly. Resetting the network settings on your device may help. 3.

Your wireless network may require login authentication or a password to access the internet. If this is the case, you will need to enter the correct login credentials or password to access the internet. 4.

There may be interference or a weak signal in your wireless network, making it impossible to access the internet properly. Trying to get closer to the road shelter or changing the wireless receiver may resolve the issue. 5.

If none of the above methods can solve the problem, it is recommended to contact your network service provider or device manufacturer for further support.

Possible reasons why there is a wifi signal and cannot connect to the wifi network:

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.

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.

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

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".

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

Reason 1: The wifi signal is relatively weak.

If a smartphone, tablet or laptop can search for a wifi wireless signal, but can not be connected, the user can look at the wifi signal strength displayed on the device, if the wifi signal is only one or two bars, it may not be able to connect, the user can get as close to the router as possible, in order to enhance the wifi signal, and then connect.

Reason 2: There are many access devices.

The bandwidth of wifi Internet access and the user equipment that the router can access are also limited, so the wifi wireless network can not increase the equipment wirelessly, in the case of very sufficient broadband, the general wireless router can access up to about 200 devices (theoretically the router can be assigned an IP address of 2-254), but considering that the general broadband will not be very large, so in fact, a single wireless router can access not many wifi devices, so in some people, And where there is a public wifi place, it is easy to have more access devices, resulting in the inability of users to connect.

Reason 3: Wireless router setting restrictions.

WiFi has a signal but can't be connected, there is also a possibility that the wireless router has set restrictions inside, for example, many families or businesses are worried about people nearby rubbing the network, so they will make advanced settings on the router, such as binding the device MAC, so that only some devices can be connected, which will cause other unfamiliar wireless devices to be unable to connect.
