The fiber modem has opened a port How to set up to use four laptops wirelessly

Nowadays, many fiber optic modems are equipped with antennas, because telecom suppliers integrated the functions of modems and routers when they designed fiber optic modems, but in order to limit one machine and one number, telecom does not want multiple terminals to access the Internet through one network, so the router function of the fiber optic modem is shielded by creating a new restricted user method in the fiber modem.

The first method: crack the fiber optic cat.

The landlord looks at the bottom of the fiber optic modem,There should be a default username and password,Users can access the management interface of the fiber optic cat through IE and other browsers (the address is generally or,There is also this address at the bottom of the fiber optic modem) Through this username and password, you can set the fiber optic modem,But you must not see its router function settings。

At this time, the landlord still has a way to solve this problem, search for how to crack the fiber optic cat through the Internet, compare in the input "fiber optic cat model + crack", you can easily find the super administrator and password, through the super administrator and password, log in to the management interface of the fiber optic cat, turn on its routing function, please refer to the relevant posts on the Internet for specific operations. After setting the dialing and password of the broadband, you can make the fiber optic modem power on and automatically dial, just like an ordinary wireless router.

The second method: add a wireless router, which is simple and convenient, 100 pieces to solve.

Your cat should be wireless, and it should work.

Broadband is opened at home,Whether all network cable interfaces on the optical modem can be connected to the Internet,This depends on the operator's settings,Fiber to the home is now the main home broadband access method in China,Optical modem has replaced ADSL's modem,It has become the most important home networking mode in China。 As far as optical modems are concerned, in fact, all network cable ports can access the Internet, but this requires the operator to open the port limitation.

The modem itself is a preliminary product of triple play integration, which can be connected to the ** network, TV network and Internet at the same time, and the ports on the modem mainly rely on VLAN binding to complete this distinction. At the very beginning, operators usually only open one port for Internet access, one port for IPTV to watch TV, and the remaining ports are reserved for opening the second IPTV, and are not opened for users.

The new type of optical modem can dial up the Internet with the optical modem, such an optical modem, you can open all the ports for Internet use, some of the current optical modems are optical modems with routing and wifi functions, and the operator's installer will set up PPPOE dial-up in the optical modem when installing the machine, so that if the rest of the ports are activated, they can be connected to the network cable to access the Internet. However, there may be a difference between 100 Gigabit and Gigabit ports of optical modems,The network port of 100 Gigabit is taken to see IPTV,The network port is a 100 Gigabit network port,If the network bandwidth of your home exceeds 100M,The Internet speed will become very slow,But there are also optical modems that are full gigabit ports。 However, the port opening and binding of this optical modem requires a little professional knowledge, and it is not recommended that users set it up by themselves, and the best thing is to find the operator's installer to set it up for you, and there is no need for individuals to master this knowledge.

If you need all the interfaces to use, you can consult the staff who help you install broadband solutions, if you have a super account and password, you can enter the more detailed cat settings setting interface....

At present, generally lan1 provides Internet access, lan2 is IPTV, lan3 is the backup port of the second broadband Internet access at home, and lan4 is the backup port of the second IPTV, and each port is independent.

What cat? At present, the super password of the Huawei cat bought on the market is generally ne7ja%5m If it is other cats, it may have to be cracked, because I am Huawei's cat myself, so by the way, I got the super password, and I will tell you by the way.

In addition, if you want other network ports to be able to access the Internet, you need to create a new network connection in the network options, in fact, you are simpler, maybe you can call ** to 10000 number, let them directly send the task, because there is a network task called TR069 in the cat, this thing is an ISP background program, so that they can directly remote.

The interface of the <> modem is shown in the figure above.

The working principle of the optical modem is that after the optical modem is connected to the optical fiber, if the signal is normal, the optical modem will automatically communicate with the switch (OLT device) in the online room, and send the serial code (each unit is unique) carried by the optical modem itself to the OLT.

Therefore, each port of the optical modem is defined by the operator's equipment room, and if the user wants to use it, he must apply to the operator's business office. (However, local operators will decide to open one or two Ethernet ports according to local conditions, and the redundant ones will not be released.)

The optical fiber cat is actually a converter, and its function is that after the three networks are in one, cable TV, **, and broadband will be sent to the user's home with optical fiber, and then the above three signals are separated from the optical fiber through the "optical fiber cat", and then connected to their respective equipment for use. Now whether the actual situation can achieve the above purpose will not be talked about first, but only your problem. The network cable out of the "fiber optic cat" is connected to the computer, and the dial-up Internet access is completed through the computer, and the upper is charged, and you only open a broadband, so other ports can not be used.

There is no router in the middle, of course, you can't go wireless, you connect the router to other ports, in fact, it is not passable, only so you can find the wireless signal, that can only mean that the wireless router itself is working normally, and the network is not connected is two different things.

The solution is: "fiber optic modem" out of the network cable to connect the route, let the router complete the dial-up Internet, from the route to the network cable to the computer, so that the computer does not need to dial up, boot on the network, after the wireless route is set, it can also be used. As for the slowdown of the network speed, after you connect it, do a measurement, and then compare it with the bandwidth you have activated.

It's also possible that your Wi-Fi isn't encrypted, causing others to use your internet and feel like it's slowing down.

First, exclude whether the setting of the route is correct, set the main letter case, it is best to unplug the other lines, and connect it after the setting is successful. Hope.
