Why is the network speed attenuation from the optical modem to the router so excessive? 30

The uplink and downlink rate displayed on the optical modem interface is your actual broadband rate, that is, 20M broadband, not the actual **speed, the two units are not the same, the broadband rate is converted to the actual **speed needs to be divided by 8, so 20MB 8=, plus the inevitable loss of network cable transmission, so your **speed in 2MB S is in the normal range.

You don't need to look at the network speed displayed by the optical modem, the 18MB displayed by the optical modem should not be normal, and the broadband you have opened should reach 100 megabits or more, right?! Connect the optical modem with a Gigabit network cable to test the network speed, and then connect the router to test the network speed to compare the actual speed test to see what the problem is. Note that the speed test should be wired, not wireless, and the wireless speed test cannot explain the problem.

In this case, you can first connect the router to the computer and re-use the speed test software to test the speed, and see the effect, if your **speed reaches about 20m s, it should be normal, but if it is not reached, you need to check to see if your router supports gigabit or whether it is a problem with the setting! The easiest way is to reset the router and give it a try! There shouldn't be any problems!!

It still feels like a router problem!

The problem of the secondary router, it is recommended to change the strong point router, if the channel interferes (it is recommended to install software on the mobile phone - wifi splitter, check the channel,), it will be affected, and the top speed is only 72mbps

Therefore, it is very important to change the router to improve the level of your intranet.

It is recommended to switch to dual band, with 5G (up to the limit, 433Mbps), while the total bandwidth, up to 1700Mbps, such as.

Can you take a screenshot of the router's management interface? Does your router dial-up or modem? At present, it is difficult to judge whether someone is rubbing the Internet, it is best to connect your computer directly to the optical modem to try the speed.

Both will affect the internet speed.

Optical fiber is generally very fast, if you are sure that the fiber bandwidth of your own grandhouse is large enough, it is definitely the optical cat at home.

And the router doesn't work. If you apply for optical fiber, you will need to pay an installation fee of 200 yuan.

Of course, this fee will vary slightly depending on the region and time.

If the broadband speed is already slow, then it is the reason for the network speed, and it is necessary to install faster broadband to solve the problem of slow network speed, which should be looked at specifically.

In the whole network, there may be bottlenecks in the following areas: the upper connection port of the optical modem, the optical modem itself, the LAN port of the optical modem, the WAN port of the router, the WAN port of the router, the wireless of the router, the quality and variety of the network cable, the type of network card of the desktop computer, the desktop computer itself, the type of wifi supported by the mobile terminal, the wifi antenna configuration of the mobile terminal, and the mobile phone itself.

In my experience in dealing with users' home broadband failures, at least 80% of the failures are in the wireless router.

Optical modems will affect broadband network speeds. Normally, the modem will not affect the original network speed, unless the modem is broken. There are many reasons for the slow network speed, the most common is the slow network speed caused by excessive optical fiber attenuation.

There is also a network congestion caused by router overload, in this case, you can turn on the router again.

Precautions for the use of optical modems.

If it is a network speed problem caused by the router, first of all, log in to the router to see if there is a phenomenon of rubbing the network, and whether there are any extra devices connected to your router, because it takes a long time to change the password, and there is a possibility that the password will be cracked. If you are rubbed into the net, there will be more machines, and the network speed will be slow.

Also, check whether there is oxidation of the network cable and crystal head, if you use inferior network cable and crystal head, the surface oxidation will increase or the contact will be poor after a long time, which may also affect the network speed. If none of the above methods solve the problem, it is recommended to change to a new router.

The solution is as follows: 1. Turn on the routing function of the optical modem: the WAN port of the router can be set to two ways: dynamic IP Internet access and static IP Internet access.

2. Set the static IP to surf the Internet, and change the IP address of the route to the same segment of the same optical modem gateway. Change the gateway address and DHCP CIDR block at the same time. 3. You need to use dial-up connection on the router side; In the router's Internet settings, select the broadband PPPoE dial-up mode, enter and password for network connection. 4. One end of the network cable is plugged into the optical modem gigabit network port (note that the optical cat port has 100 megabit is used for TV, and there is no network if you make a mistake) Secondly, whether the telecom optical modem IP overlaps with the router IP, if it overlaps, you need to modify the router IP, otherwise there is no network, (Prompt * Some users want to change the router password by themselves,。

5. However, after resetting the router, you can not connect to the Internet, and you can change the router password to power on without connecting to the optical modem.

Looking at the frequency band and rate of broadband, in general, optical modems have little impact, and routers are a little more.

It can be said that the optical modem can play the total bandwidth limit. However, modems generally cannot set network equalization, intelligent control, and connection limits. Therefore, as soon as there are many clients, they will blame the problem!
