The router M2 light is either always on or often off, and kneel down to ask the master to solve it

Poisoned, it may be an ARP virus, what kind of firewall and antivirus software are you installing, and is the antivirus software of each machine updated frequently???

You can install ARP to kill and see, and the router should also be set up, it is best to bind an IP address to each machine, and the DNS address is in the router, and then the router is enabled to enable ARP binding.

You first use only one machine to connect the router and modem to see if the router can connect to the server and surf the Internet normally, if it works, then connect to the router or switch one by one to see if there is a problem with that machine.

If you can't connect normally even with a machine, then try swapping routers or checking the next ** line.

Or just ask someone from telecom to take a look at the line.

What's your M2 light indicating?。。。

I've had problems like this! Don't know if your routing default gateway is separated! For example:

Route 1: The default gateway is Route 2: Even if you open your LAN separately, you can't have just one, but two. There are often two lines that conflict and go down because it can't exchange data! The simple solution is also the final one:

It's to buy a dual-WAN router! I don't know if you've heard of it? (This kind of route can enter two broadband or more than two broadband routes) only one default gateway Your LAN can be shared no matter how many computers you have, and all computers can share 2 broadband can achieve 2m+2m=4m traffic!

Some time ago, I changed to a Flying Fish double WAN router for about 860 yuan! Many of the original network problems have been solved, I hope it will help you!

M1 flashes approximately once per second, indicating that the system is running. M2 is on, indicating that the system is busy at this time.

M1 is the power indicator of the router, which means that the power is turned on, and it flashes about once a second, indicating that the system is running.

M2 is the network connection indicator of the router, and it is always on to indicate that the system is busy at this time. A flashing light indicates that there is data flowing. The faster you flash. If the traffic is large and does not light up, the network is not connected.

Each lamp has a certain meaning, you have to know the function of each lamp, what brand of routing you use.
