After the WIFI is connected, it shows that the Internet is not available and the light is flashing?

wifi is connected and cannot be connected to the internet causes and solutions.

1. The router is unstable.

There are wireless routers.

Optical Cat (Broadband Cat.

The quality is relatively poor, and a series of problems such as crashes will occur after long-term operation.

Solution: Turn off the power of your home wireless router and optical modem (broadband modem), wait for a few minutes, and then turn on the power and start the device. After the normal start, connect to the wifi test to see if it can be used normally?

WiFi is connected and not available for internet access.

Second, the broadband is faulty.

If your home wifi was connected to the Internet before, suddenly there was a problem of not being able to access the Internet. And the router and cat have been powered off and restarted, but it still can't be used after connecting to wifi.

In this case, it is very likely that there is a problem with the broadband line, or the broadband is in arrears.

2. If there is no arrears, you can transfer to the manual customer service, report the fault, and let the operator arrange staff for maintenance.

PS: If you don't know how to dial up the Internet with a broadband connection in your computer.

You can read the tutorial below to see how to do it.

At this time, if the computer can access the Internet, it means that the broadband line is normal and there is no problem. On the contrary, if the router is not used and the computer is directly connected to the cat, the computer cannot access the Internet, and most likely there is a problem with the broadband line.

After the wifi connection, the display is not on the Internet, the lights are flashing, if the wifi connection shows that the network can not be on the network, it means that the network is not busy, it is crooked, so the wifi connection shows that the network is not online, the lights are flashing, how to show that the wifi connection can not be on the network, that means that the network is not busy, that is, the wifi is unlocked, so he can't go to the network, this is also a problem.

In this case, the reason may be that there is a problem with the bandwidth and password set in the router, and the login cannot be successfully registered. Wireless router, wireless lights keep flashing, the computer shows that it is connected, but it can't access the Internet.

Reboot, no look at the settings.

The solution to the wifi yellow light keeps flashing and can't get on the network is as follows:

A yellow light indicates that the WAN port is not connected to a network cable, or that the contact is poor. It is recommended to change the short network cable with the computer and the WAN port connection test to see if the blue light will flash, if it is also a yellow light, it means that there is a problem with the WAN port, if the blue light flashes, it means that the network cable needs to be replaced.

Self-checking router:

1. Check the network cable connected to the router, especially the bus that needs to be connected to the broadband port.

2. Log in to the router to check whether the settings are correct, or whether there is any problem with the broadband account and password entered.

3. You need to pay special attention to the capitalization of the letters of the broadband, if there is no problem with the above, check whether the broadband is in arrears.

1. Normal flashing, signal light flashing means that there is network data in transmission.

2. If the mobile phone can be connected to wireless but cannot be used, see if there is a problem with the router's Internet parameter settings, if it is suddenly unable to access the Internet, it is recommended to restart the router to see if it can be solved.

Wireless routers.

It is a router with wireless coverage function for users to surf the Internet. A wireless router can be seen as a device that sends broadband network signals from the wall of your home to nearby wireless network devices (laptops) through antennas.

Wifi-enabled mobile phones, tablets, and all devices with WiFi function). Popular wireless routers on the market generally support four access modes: dedicated line XDSL cable, dynamic XDSL, and PPTP, and it also has some other network management functions, such as DHCP service, NAT firewall, MAC address filtering, dynamic domain name and other functions. Popular wireless routers on the market generally can only support 15-20 devices at the same time.

The signal range of a general wireless router is 50 meters, and now some wireless routers have a signal range of 300 meters.

The wifi light is on normally but the Internet cannot be accessed, and the solution is as follows:

1. Check the router settings

Step 1: Open the browser of the computer connected to the current wireless router, enter part of the router in the address bar, check the bottom label of the router to know), log in to the web configuration interface of the current router, and the username and password are admin by default

Step 2: Under the network settings of the router, first find the WAN port setting option of the router. The correct "type" here is the crux of the matter.

There are two commonly used types: PPPoE and DHCP. Choose this according to your own situation. If it is a home ADSL dial-up Internet access, choose PPPoE; If there is a direct network interface available, such as cell broadband or a hotel, DHCP is chosen

Step 3: If it is DHCP, there is no need to make other settings, and the router will automatically obtain the corresponding network settings. If you choose PPPoE, you need to fill in the correct username and password, which are provided by network service providers, such as China Telecom, and if you forget your password, you can call 10000 for manual consultation.

Step 4: Next, check the LAN port settings of the router. The settings of different brands are actually similar, the most important thing is to turn on the DHCP function, so as to ensure that the router can assign an IP address to the device when it is connected to the LAN port or connected to WiFi, and the IP address range assigned by DHCP should be in the same network segment as the IP address of the router, for example.

Step 5: Finally, check the security settings of your router. Check whether some security policies restricting MAC or IP address connections are enabled, or the corresponding rate limiting policy, if yes, turn it off, otherwise only devices with specific MAC or IP addresses can connect to Liangla.

2. Check your phone settings.

Step 1: Open your phone's settings, select "Wi-Fi", and then, when you see the wifi signal that you are currently connected to, click on the small blue circle arrow on the far right.

Step 2: Click on "Ignore this network". Then, the wifi connection of the mobile phone will be disconnected, so that the mobile phone will not automatically connect when you click to connect to the signal source again, but will re-enter the connected wifi password, that is, the mobile phone will re-identify the network once, so that you can achieve the effect of emptying the original network configuration.

Step 3: If you want to clear it more thoroughly, you can open Settings ---General --- Restore and select "Reset Network Settings". In this way, the device will restart, and after the restart, all previously connected networks will not be saved, but will be recognized as a new network, and the wifi password will be entered to connect to the <>

First of all, check the broadband connected to the router, and replug the network cable to see if the broadband itself has no network. If there is no problem with the bandwidth, try resetting the router.

If the WAN port is abnormal, it means that there is no network for the network cable, and you can check whether the router is connected to the modem normally, or call the operator to solve the problem. If the Wi-Fi light is abnormal, the Wi-Fi is disabled or abnormal, you can restart the router or reconfigure the router.

Principle: The devices in the network communicate with each other mainly with their IP addresses, and the router can only use the specific IP address to ** data. An IP address consists of two parts: a network address and a host address.

In the Internet, subnet masks are used to determine the network address and host address. The subnet mask is 32 bits, just like the IP address.

And the two are one-to-one correspondence, "1" in the subnet mask corresponds to the network address in the IP address, and "0" corresponds to the host address, and the network address and the host address constitute a complete IP address. In the same network, the IP addresses must be the same.

Summary. Hello, wifi signal regardless of whether there is a network mobile phone and other equipment can be connected, the user can not use the network after connecting to wifi, first confirm whether your broadband line is smooth, you can check whether the indicator light of the broadband cat has LOS red light flashing, if there is a broadband failure, so the router's wifi can not use the network, at this time, the user can call the operator's customer service to report the fault processing, after the fault report, there will be staff to come to the door to troubleshoot.

If the broadband modem can be connected to the network normally, then it is a problem with the router, and you can check whether the network cable is connected correctly. If the network cable between the broadband modem and the router is normal, you can restore the router to its factory value, and then reset the router parameters to see if it can be restored to normal

2. Then open the browser and enter the management address and login password of the router.

3. After logging in to the background, click the setup wizard, and then fill in the corresponding parameters according to the wizard instructions.

6. After the wireless setup is completed, click Save, and then restart the router to use it normally.

After wifi connection, it shows that you can't connect to the Internet, and the lights are flashing?

Hello, wifi signal regardless of whether there is a network mobile phone and other equipment can be connected, the user can not use the network after connecting to wifi, first confirm whether your broadband line is selling smoothly, you can check whether the indicator light of the broadband cat has los red light flashing, if there is a broadband fault so the router's wifi can not use the network, at this time the user calls the operator's customer service to report the fault processing, after the fault report, there will be staff to clear the wheel barrier. If the broadband cat can be connected to the Internet normally, then it is a problem with the router, and you can check whether the network cable is connected correctly. If the network cable between the broadband modem and the router is normal, you can restore the router to its factory value, and then reset the router parameters to see if it can be restored to normal

1. First of all, the router is connected to the broadband modem computer, as shown in the figure: 2, and then open the browser to enter the management address and login password of the router. 3. After logging in to the background, click the setup wizard, and then fill in the corresponding parameters according to the wizard instructions.

4. Select the networking mode is generally pppoe, and then click Next to enter the broadband account and password, click Next: 5. After the broadband parameters are set, enter the wireless setting interface, and fill in a wireless name and password as shown in the figure: 6. After the wireless setting is completed, click Save, and then restart the router to use normally.

Have a great day. I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

Step 1: If there is a problem with the optical interface of the optical modem, you need to replace the optical modem.

Step 2: The indoor pigtail connection optical modem connector is loose, and the connector can be restored by plugging it in.

Step 3: If the indoor part of the optical fiber is bent too much, the optical fiber can be smoothed.

Step 4: If the optical fiber of the outdoor part is broken or the optical port of the equipment in the computer room is faulty, you need to contact the staff for guarantee processing.

The optical signal indicator of the optical modem LOS flashes red, indicating that the device has not received the optical signal.

Suggestions: 1. Restart the optical modem;

2. Check whether the bending angle of the line is too large and the phenomenon of extrusion;

3. Check whether the optical fiber interface is loose and plug in the joint;

If the above methods still do not solve the problem, you can call the customer service of the local operator to report the broadband fault.

The broadband modem keeps flashing a red light, but the router signal is full but can't get on the network, what is the reason?

Flashing red light is faulty, generally cats have several indicators, a power indicator, an operator signal indicator, an indicator connected to the PC, if the line indicator is not lit, it is a line failure!

Solution: 1. Turn off the power and restart the router.

2. Then press and hold the reset button on the back of the router.

3. Open the browser and enter, enter the user name: admin password: admin, different brands of routers input content is different, see the router description for details.

4. Find the wireless settings page, turn on the wireless function, set the name and password of the wireless network, and you can reconnect it.

You follow the steps I said, set the wifi back and try it:

1.Turn on the power supply, then plug in the network cable, plug in the WAN port (generally the blue port), and then connect the network cable with the computer to plug in any LAN port, after doing these jobs, then you will see that there is an address and account password behind the router, after connecting, enter the address you see in the router in the browser, generally of course, if your home is using ** online network, then you have to prepare an additional modem, commonly known as "cat")!

2.Then enter, enter the corresponding account and password, generally the new ones are admin!

3.After entering the operation interface, you will see a setup wizard on the left, Attack on the entry (usually pops up automatically)!

4.Click Next, enter the Internet access method settings, we can see that there are three Internet access options, if your home is dial-up, then use PPPOE.

Dynamic IP can be used by plugging the computer directly into the network, and there is a DHCP server on the upper layer.

The static IP is generally a private line or something, or it may be a cell bandwidth, etc., and the upper layer does not have a DHCP server, or wants to fix the IP.

Because of my dial-up internet, I chose PPPoE.

5.If you choose PPPoe dial-up Internet access, you need to fill in the Internet account and password, which should be understood by everyone, and there will be an account number when you open broadband!!

6.Then the next step is to enter the wireless settings, we can see the channel, mode, security options, SSID, etc., generally SSID is a name, you can fill in as you like, and then the mode mostly uses 11BGNFor wireless security options, we need to choose WPA-PSK WPA2-PSK, which is so safe that it will not be hacked and rubbed by the network.
