Kneel down and ask for a master s answer! Using a router to disconnect for no reason

Did you fall for the legendary ARP?

1. Reset the router and then reset the router.

2 Maybe it's because the router is on for too long, you unplug all the cables, wait 10 minutes and then connect it.

You should be a router automatically dialing up the Internet bar, why is the desktop disconnected, and the laptop is also disconnected? There should be no interference, check your computer, whether it is in the ARP virus, your desktop has been simulated as a router, your laptop thinks that your desktop is a router, so connect the network from him, once the desktop is broken, the router is also disconnected. And when you play games, the network is unstable, it may also be caused by a virus, first physically disconnect your desktop from the network, and then check the virus well!!

Are you pulling the distance too far?

It may be poisoned, ARP virus, it's best to find an ARP killing tool to kill it, and if your router is bound to a MAC, it's best to bind the MAC of 2 machines.

The network is disconnected at a fixed time, and I think it is a problem with the routing settings. The DHCP of the general route has a time limit, some default 120 minutes, some 2880 minutes (2 days, the maximum value under the dynamic IP), the default value is different when the brand is different, so that the automatic IP will be disconnected when the corresponding DHCP time will be reached, and the computer or router can be restarted. If you try to restart the computer when you have an accident, if you can get on, you must access the route DHCP time expires.

If you can't get on it, because you have two routes, it may also be due to the expiration of the DHCP of the upper route to the lower route. You must at least bind the MAC code corresponding IP to the topmost route to the lower route, so that the lower route will not have DHCP expired, and the time value of DHCP for the two routes is set to large (2880 minutes), it is estimated that you will not have a computer or a device connected to the route to open it for 2 days. If it is more than 2 days, it will also bind its MAC code to the IP in the access route, so that there will never be a DHCP expiration.

My wireless routing cat has often been able to have this kind of problem recently, and the problem is more serious, sometimes the route will be accompanied by a route restart after the line is dropped, but the time is not fixed, generally in 36 hours to 48 hours automatic restart once, once changed the wireless password, and then 3 days or so the route has not been restarted, and then I know that someone told the wireless password to others before, probably due to the load before the line dropped.

You bind the MAC address in the route and try it.

This is a common problem because the router also has to rest. I've used n routers and have this problem. If you want to unplug the power supply, plug it in and use it. If you don't want to drop the connection, you have to buy those high-end routers. of the left and right. It's stable. It's okay if you don't close it all year round!

The router has a manual, you can re-set it according to the manual, and generally there will be no such problem, except that it will strike if it is not closed for too long, but this too long time refers to more than 20 days, and it is by no means 24 hours, it is recommended that if you re-set it or so, go to the place where it is sold, let him take a look, there should be a problem

I've also encountered such a problem, I remember that I changed the dial-up connection method in the WAN port settings in the network parameters of the road tour, if you don't turn off the road game and the computer for a long time, you can try to change it to a manual connection.

If that doesn't solve the problem, it is recommended to put a small eye around the tour, prick it with a straight pin for three to five seconds, restore the original settings, and then wait for it to return to normal and then set it up again.

If you have a problem with the router OS, you can re-upgrade and flash the router OS! I've had this problem with Tengda's wireless router before!

This problem may be that there is timing interference around you, and when it is turned on at a time, it will interfere with your wireless signal, and this signal can be in the same frequency band as you, causing the connection to drop.

In addition, there may be no anti-rubbing settings, and people are forced to drop the connection by logging in.

It has nothing to do with router settings, there may be two problems: 1. There is a quality problem with the route itself 2. Whether there is an ARP virus in the computer.

If this happens, you can power off the router and restart it, and the process will take about ten seconds. The reason is probably that you don't usually turn off the route.

This one needs to rest just like people. You're going to turn it off when you're not using it and dissipate it. If you don't believe me, you can try it first.

Router settings, you're looking, there is timing, and, whether it's because someone logged into your home router and tampered with the settings. If it doesn't work, you can find a manufacturer.

If possible. Rebind the NIC, and tell you the reason if it's good.

The router is too bad, and the router we used was fine after 3 months of dual wan.

My wired router is also getting old. Sometimes it doesn't take more than 30 seconds to drop.

Could it be that the lease period of the A router is too short.

1.Set up the issue.

2.Firmware issues.

You can see if your cat is broken, I had this problem the other day. Causes periodic disconnections.

Or it could be caused by a problem with your firmware. Try flashing an earlier version of the firmware.

Is it a timed attack?

This is because Lu You was poisoned, which caused Lu You to be unable to dial normally, and my Lu You was also a problem. Appear.

It could be that there is a problem with the cat and router settings.

Hardware connection: home ** line cat router wan port router lan port computer network card (wireless network card receiving).

1.Disconnect the router from power.

2.Press the reset button or hold down the small hole (reset button) on the back of the router with a toothpick.

3.Plug it back in.

4.When you observe the sys light flashing, release the reset button. After that, the router will be restored to its factory state.

Note: Do not turn off the power before the router is fully booted, otherwise, the configuration may not be restored to the factory defaults.

Turn off the power if necessary, and turn it on later.

The above method does not work, and then restore the router to the factory state, reset, save, and restart the router.

1. It is recommended that you use a single machine to try it and see if it will be disconnected! Use one first, don't connect the other, and then switch to another when you're done.

Maybe it's a machine virus!

2 If the experiment still drops, it is recommended that you change the route, try the new route, and the newly purchased route may also be bad.

The new router may not be able to work, some insiders you don't know, some business halls use the router top switch in order to solve the problem of no switch, and then wait until there is a switch to replace it, maybe when the router is broken.

Is it a mobile network, or a telecommunications network. It's a network problem, not a setup problem, not a quality problem with the router itself.

Electronic devices have a lifespan, almost up, my D Link DIR-624 also often, just replace it with a new one, and first redo the cable head, replace the elimination method to try.

Suspect that your bridging was not successful: If you are using a Layer 2 bridge, the secondary router needs to turn off DHCP and enter the MAC address of the other router into the bridging table. Plus, there's no problem with the communication between your main and secondary routers.

If there is poor communication between the routers, the secondary router will not be able to connect.

It seems that wireless bridging TP-Link is possible, W3C can not be bridged, when bridging, you must set up wireless, one by one, and the channel of the router should be set, and then connect it, you must ensure that your router has a bridge function, otherwise it cannot be bridged, and the back should turn off DHCP and use the DHCP allocation of the main router.

Using a static IP address assignment will do just fine.

You see if the IP addresses of the two computers are conflicting.

0) Prepare two network cables, one to connect the computer network port to the LAN port of the router, and the other to connect the LAN port of the cat to the WAN port of the router.

1) The router is powered on, and the cat is powered on.

2) Find the router's manual.

3) Find the management IP of the router (generally or or, login account password, login ** example -->

4) Statically set the IP address of the computer host and the management IP in the same network segment (if the router is enabled by DHCP function by default, then set the computer network card to automatically obtain the IP).

5) Log in to the wireless router management interface.

6) Turn on the DCHP service.

7) Set up PPPoE auto-dialing function, permanent connection (8) Turn on the wireless function, set the wireless Internet password (if it is an unlimited router) so that you should be able to automatically dial up the Internet, wired and wireless can be used at the same time.

There is a connection mode in the router, connect on demand, or start the connection, etc., to see if it is a problem, and there is a problem with your computer settings, whether the wireless network is set to automatically disconnect, and in some cases, in order to save network traffic costs, the default is set to automatically disconnect.

Obviously, machine 2 should have been infected with the ARP virus. You can try to turn on both machines, and then turn off machine 2 There is no disconnection, if there is a problem with machine 2, if it is disconnected, restart the router Try it, if you can surf the Internet normally, it is an ARP attack, go to the Internet to find a way to completely solve the ARP attack, antivirus is not able to detect and kill the ARP virus, because the ARP virus is attacked by using Ethernet vulnerabilities.

The outside line is unstable.

It is likely that it is a coincidence that your outside line is unstable.

If the network is disconnected when you open 2, it is obvious that there is a problem with the interface of the 2 machine or router (try to change the interface), and check whether the IP address of 2 conflicts with the IP address of 1.
