Tianyi wired broadband connection Tengda wireless router, why can t the mobile phone find wifi signa

It is recommended that you follow these steps:

1。Disconnect the router from the telecom cats first, 2. Unplug the end of the computer that was originally connected to the cat and plug it into the LAN port of the router (the light with a number will turn on).

3。The wireless router ensures that the factory settings are protected from the effects of previous settings. Log in to the router, 19216811 or 19216801, enter it correctly in IE and log in to the router according to the manual.

4。Go to the router settings page to skip the wizard and go directly to the LAN port settings, change the LAN port address of the router to save and restart the router. Note that you can use it when you log in to the router in the future, instead of using 19216811

5。After restarting, connect the network cable out of the cat to the WAN port of the router, use it into the router settings page, and then skip the wizard directly to the WAN port settings, select dynamic IP for the connection type, save it and see if the WAN port obtains the IP address after saving the router running status (generally wait for 5 minutes), and then try whether the computer can open the web page, if the connection is normal, then enter the router to set up the wireless part of the function, and the rest can be operated according to the manual.

6.Turn on DHCP, note that its network segment should be the last to remember to save every step and finally restart the router in the router settings.

Summary. 1.Hidden wifi signal.

Most routers have the function of hiding the wifi signal, mainly to prevent others from maliciously rubbing the network, if the router's wifi signal is hidden, then it will not be searched. To remove the hidden WiFi signal, we can log in to the management address of the router, go to Routing Settings - Wireless Settings, turn on the wireless function, and check the box in front of the wireless SSID broadcast, at this time the WiFi signal can be searched.

2.The terminal device does not support the WiFi signal in the 5G frequency band.

Some routers are dual-band routers, and some mobile phones and computer devices only support frequency bands, and you can't find wireless signals in the 5G frequency band if you search for them. Dual-band wireless routers need to check the wireless status of 5G in the management interface and wireless settings, check whether the SSID number of the wireless router contains Chinese or special characters, and the wireless channel selection is wrong.

2.The terminal equipment does not support the wifi signal of the 5G frequency band, and some of the Zen sell the dust router for the dual-band router, and some mobile phones and computer equipment only support the frequency band, if you search for the wireless signal of the 5G frequency band, it is not searchable. Dual-band wireless routers need to check the wireless status of 5G in the management interface and wireless settings, and check whether the SSID number of the wireless router contains only Chinese or special characters, and the wireless channel selection is wrong.

3.There is interference in wireless wifi signals such as microwave ovens, cordless **, wireless mice and keyboards and other devices and routers are working in the same frequency band, if the separation distance is close, there will be interference between each other, which may affect the signal strength of the wireless router. At the same time, the distance between the terminal device and the wireless router is too far away, and there are partition walls and obstacles in the middle, which will cause the wireless WiFi signal to be seriously attenuated, which may lead to the inability to search the WiFi signal of the wireless router.

Can't find the router's wifi signal, then I suggest you check whether a single mobile phone or computer can't find it, or all mobile devices can't find wifi, all can't find it or it's better to solve, it is recommended that you restore the router to factory settings and reconfigure the new configuration. If a single mobile phone can't find wifi, then it may be that there is something wrong with your phone's system or settings.

Summary. 1. The mobile phone cannot connect to the wifi due to the wireless router device, which is the reason why the vast majority of mobile phones cannot connect to the wifi. Due to the privacy and anti-rubbing behavior of the router, it will filter MAC addresses to a certain extent.

This causes the phone to not be able to connect to wifi.

Solution: So for this situation, you need to first check if your router has created a MAC filter address. The specific operation method is to add the MAC address of the mobile phone to the rule, and then open it in this order:

1. The mobile phone cannot connect to the wifi due to the wireless router device, which is the reason why the vast majority of mobile phones cannot connect to the wifi. The router will filter MAC addresses to a certain extent due to its own confidentiality and anti-rubbing network trembling behavior. This staring at the cave waiter caused the mobile phone to not connect to the wifi.

Solution: So for this stupid situation, you need to first check if your router has created a MAC filter address. The specific operation method is to add the MAC address of the mobile phone to the rule, and then open it in this order:

2. If the user sets up a hidden router, the mobile phone will not be able to connect to the WiFi normally, so you need to enter the SSID and password to connect to the wireless network. It is impossible to connect to the wireless office network by searching alone, which you need to pay attention to. Workaround:

You need to manually connect the WiFi address on your mobile phone, and turn it on according to the following steps: Settings - Wireless Control - Key to turn on WLAN - WLAN Settings - Add WLAN network. The steps vary slightly from phone to phone, but in general it is done as follows.

You'll then be able to search for Wi-Fi. There are other reasons that your phone's hardware is broken, which requires you to take it to the repair point in time for repair; In addition, it is also possible that you are too far away from the wifi signal source, resulting in the phone cannot find the weak signal source, or your phone and the signal source are previously blocked by a medium, such as a wall, these are the reasons that cause your phone to not be able to search for wifi. Therefore, as close as possible to the wireless wifi, you can greatly increase the chance of finding the wifi.

You can change the wireless parameters of the router!

1. Change the wireless signal name of the router, in the subsequent page, click "Advanced Settings" - "Wireless Settings" - "Wireless Basic Settings", find "Wireless Signal Name (SSID)", and set the wireless signal name you want (number, letter or combination of numbers and letters) by yourself.

2. Change the wireless channel, click "Advanced Settings" - "Wireless Settings" - "Wireless Basic Settings", find "Channels", and select These three channels are less interfering and more stable.

Change the routing SSID,It's best to change it to a similar SSID for telecom Netcom,,And then set the channel,If there are not many wireless devices,Then you lock the MAC,I believe it's good。

Is there too much wireless near your home, the wireless channel is set below 10, don't set it to automatic, and often change the wireless channel.

The WAN port displays the solution to the failure of the connection.

The WAN port displays the troubleshooting method in the connection.

The WAN port shows that it is connected but cannot connect to the network.

Turn off software such as Security Manager and try setting it up.

2. If you can search for other wireless signals and can't find your own wireless signal, it is recommended to modify the wireless settings of the router - modify the SSID - select the cover eggplant or 11 channels, and search for the rubber stuffy banquet again after confirmation.

1. Try borrowing other wireless network cards to see if you can search for the wireless signal of the router and confirm whether it is a router failure, some wireless network cards may not support frequency bands, modify the frequency band of the wireless signal, and change it to see the signal within 1 to 11. PCJ China Routing Network, and when the wireless router is turned on, the indicator light of the wireless WLAN is constantly flashing, and the wired enters the router management interface to confirm whether the wireless function is turned on. Adjust the position of the wireless router or wireless network card to avoid the situation that the wireless network card is in the dead zone of the router.

2. According to the author's experience, the network can be divided into two categories, one is the cause of the device itself, for example, the hardware problem of the device itself constitutes the network is unstable and connected, or the interface quality of the hardware itself constitutes the network connection is not dredged; The other type is software problems, such as defects in parameter settings or viruses. Therefore, our analysis of this example problem should also start from these two aspects.

3. If a client computer virus, especially an ARP fraudulent worm, is provoked, then when a satisfactory virus packet accumulates in the network, a lot of traffic will hit the port of the broadband router, and when the traffic is too large, the router port will self-maintain, that is, the port will be automatically closed to invalidate, so as to discard all virus packets. At this time, the client computer will appear to be disconnected and unable to connect to the external network; And when the broadband router self-maintains and closes the port, the virus packets are discarded, so the port will automatically return to normal in a short time (less than a minute), which is why this reader encounters a theoretical disconnection problem and returns to normal in about a minute.

Fourth, when the shortcomings are caused by ARP fraud virus, we should first patch the operating system of each client computer to compensate for various gaps, and then update the virus database of the device antivirus software to check and kill worms, and if necessary, we can also contact ARP

d**ARP cache information is restored to normal network. It only takes a complete virus to restore the network to normal and deal with the automatic disconnection problem mentioned above. Of course, for some of the more violent ARP viruses, we can only rely on things to deal with, such as an ARP firewall on the local device or the binding MAC function of the router at the beginning and end of the router to bind the invasion and transmission of the virus, these are very effective prevention methods, and the effect is obvious in the author's theoretical application and maintenance process.

First of all, see if there is any arrears. Then go to the webpage and open the router settings to see if there is a broadband connection.

It may be a problem with the wifi channel, the general domestic mobile phone can support almost any wifi router, and the imported mobile phone generally does not support the 13 channels of wifi, you change the channel of the wifi router to try.
