How to see if a router is good or bad

There are many reasons why the Internet is slow, and it doesn't have to be the router. You should first check if your computer has any viruses; Among the users who use this router, there is no P2P software, such as Thunderbolt, QQ Whirlwind, BT, etc. Then you can plug the main line into a single computer and use it first.

If there is a significant increase in speed, it should be a LAN problem. On the premise that there is no virus, you can limit the speed in this P2P software. The current ** software provides this function

For example, you also have speed limits and no viruses. Your main internet cable is also in good shape. At this point, take a look at the router's configuration.

In general, the MTU value of FTTx+LAN is 1500, and the MTU value of ADSL is about 1480-1492. If you've checked all of these settings, it still doesn't work. You can ping under DOS.

Under DOS, enter: ping -t to test more, if there is packet loss, and the packet loss is serious, it is the fault of the routerIf not, you should still check for LAN issues.

It mainly depends on the size of his throughput.

The Internet has developed rapidly in recent years, and WiFi has basically spread to every household. In fact, the wifi we are talking about is the "router", and it is easy to have this or that small problem after a long period of use, for example, some routers often have the problem of "suddenly unable to use it", which is the reason for their own software settings, or the router is broken, today I will introduce to you the inspection method to judge whether the router is bad or not.

Model: TP-linktl-R406

Method 1:

If the router used is disconnected, then first check whether the power indicator and network indicator on the router are normal, if there is a serious hardware failure inside the router, the indicator will not be displayed normally. So we can tell if the router is broken if the indicator light on the power supply is normal, and if the indicator light is not on, then it is obvious that the router is broken.

Method 2:

People who have spring pants will encounter this situation, that is, although some routers are broken, the indicators are still on normally, but the connection network will be disconnected or extremely unstable. The solution is to ping the network address.

Method 3:

If you have more than one router in your home, you can replace the other routers and reset the password. If everything is fine, then you can be sure that the previous router is broken. If the problem is still not solved, it may be a problem with the coverage of the broadband line.

1. Check the router settings and network settings, mainly IP and DNS, and set the addresses of the modem and the router to different IPs;

3. Directly use the optical modem to connect to the Internet and check whether the network is smooth;

4. Insert the other end of the network cable plugged into the wireless port into any WLAN port of the router, try to connect to the Internet with a computer, if you can connect to the network, it means that there is no problem with the network cable between the router and the optical modem, in addition, you can also use another regret cavity to connect a network cable without problems to determine whether the original network cable has a problem;

5. Observe whether the light corresponding to the WLAN port plugged into by the network cable connected by the computer host and router is always on, if not, it means that the network between the two is unblocked;

6. Through the above steps, you can determine that there may be a problem with the router;

7. Disconnect the power supply of the router, wait for it to dissipate heat, reconnect the network cable, and observe the network connection. It can be repeated several times, and if it really doesn't work, you can be sure that the router is malfunctioning.
