The 2M network speed is super slow, why did the network speed suddenly slow down. The original 2M in

According to my analysis, it is controlled by someone through routing.

Since there are times when the speed is fast (when the route rate limit is turned off) and there is still a slow time on your own (someone forgot to turn off the route rate limit before shutting down).

There is also the question of checking the Internet about routing.

In a small LAN, there are gods who control the route, and all the software is crooked, so it's not good to do a good job of ARP defense and ensure that the machine is connected to the route.

Of course, the main thing is to learn how to use routing (very simply).

If you are sure that you are not restricted, it is possible that you have been infected by the ARP deception virus, and it is the same as others restricting you, and you can't access the Internet. You said anti-virus, I don't know what anti-virus software you use, ** definitely not, you put the firewall in the next Kingsoft ARP, see if you have every outward ARP attack! If there is, it is poisoning!

But it may also be a network cable problem! At the same time, let's see if someone else has the same problem! It is recommended to reinstall the system!

Check the computer system carefully, and if there is no problem, you can contact the community manager to check the background data.

You can take a speed test** to check your internet speed.

Is it wireless? Is it possible that someone will steal it? Also, your computer can't work.

The speed is correct, but the unit is wrong, and the 2M bandwidth mentioned by Netcom is actually the rate of broadband, and the full writing is 2Mbps

It's not what we usually call 2MB. The rate unit is fundamentally different from what we usually call KBMBGB, and they can be converted into units: 1Mbps = 1024Kbps

1mb=1024kb

But. 1kb = 8kbps, the calculated value (theoretical value) of the ** speed of 2Mbps rate broadband is: 2Mbps divided by 8 = (1024Kbps * 2) 8 = 256kb, that is to say, the speed of 2m broadband ** is basically maintained at about 256kb, but this is a theoretical value, in addition to the line loss on the network, weather and other uncertain factors, we can generally reach more than 200kb ** speed is normal.

Of course, sometimes the network line is abnormal, which will make your ** reach a high value, but this generally does not last too long. As for the 2m optical fiber Internet access used in your company, its speed is essentially different from the way you use ADSL at home through ** Internet access, which cannot be compared. There is also the fact that Netcom is not garbage, Netcom and Telecom are the two largest network operators in China, both occupy China's **, broadband and other services, there is such a saying in the industry, in China is North Netcom, South Telecom.

The meaning is very clear, China's northern cities are all Netcom, while telecommunications are in China's southern cities.
