The router has been unable to connect to the Internet since it suddenly dropped 20

Can I dial directly to a computer? There will be an error if it doesn't work**.

738 739 NIC is disabled or broken. Enable NIC or change to a stand-alone NIC

The kind of cell broadband that doesn't have cats? Direct customer service.

Check if the cat is working properly!

If you use virtual dial-up Internet access, you must set the correct username and password.

This should be Netcom's DNS port and the router link is not through, you can operate as follows, at the same time unplug the power of the Netcom cat and the router, a new IP will be automatically generated after an hour, and then plug in the cat, and then connect the router for a new network calibration (username + password) After calibration, you can go directly to the Internet, confirm that there is no problem with the Netcom network, and then plug in the router to set up, Netcom If there is a username and password, it needs to be set, after setting, hit ** to ask Netcom's DNS server to be selected and selected, Just fill in the router.

First directly connect the cat to see if you can access the Internet, if there is no problem, look at the router settings, it may be that the network signal of Netcom is faulty, **Check and check, report for repair.

It is not a wireless router.

Determine whether it is a routing problem or a circuit problem, and then determine whether it is a problem with the intranet or a routing problem.

You first check whether the crystal plug of the network cable is loose, click on the computer, then open the device manager, find the network adapter point to deactivate, and then start it, maybe it's fine. If not, don't be offended! Take a look at the following methods, you may wish to use measures that you feel acceptable, and thoroughly organize your love machine, and you will not have this kind of phenomenon.

A: Users who often surf the Internet for up to half a year should open the shell of the device after the power is off and clean up the dust inside the device. b: Place the equipment in a safe place for people, open the lid of the equipment, use air convection to strengthen contact with the air, and naturally dissipate heat;

c: Install a micro fan to the equipment to increase the convection of air and force heat dissipation;

D: If you are doing IT, I suggest that you install a heat sink on the heating part of the device after disconnecting the power supply.

e: After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes up and down the equipment to strengthen the air convection flow and improve the heat dissipation conditions;

f: To ventilate and dry the equipment, it is best to make an insulated heat dissipation bracket (there are also notebooks on the market) to support the equipment for natural heat dissipation;

H: Let the adsl cat sync first: power off the cat and restart it.

i: The software settings are reasonable, so that 3 do not install: do not install informal software, do not install P2P (occupy resources) software, and do not install infrequently used software.

Turn off all unnecessary network connections, such as Thunderbolt BT Donkey, etc.;

j: Optimize the network Personally, I recommend using some gadgets, such as Super Bunny, Optimizer or 360, etc.K: The computer should have at least one effective and genuine antivirus software installed, and the firewall settings should be appropriate (not too much, too high).

l: NIC problem: The NIC has appropriate bandwidth and stable operation.

As long as you take care of our brothers (routers, cats, Hubble, network switches and their computers), our brothers promise to truly do: "You respect me, I respect you" for your faithful service. Otherwise, ride a donkey and read the record book--- let's see!

Thank you for my answer!

Thank you: friend!

If so, there may be a problem with the firmware cache, you can solve it by resetting the router, by first powering off, then find a small hole in the back of the router (reset reset), hold it with a toothpick, and then plug in the power supply for 5 seconds and then put it back, the router will be reset, and you need to log in to the router again to set up the Internet account and password after the reset.

This has little to do with buying at home and abroad, and it is recommended that you choose to check whether there is any virus on your computer. Or simply redo the system and try it again.

Your router's performance is not good, and if your network problem is ruled out, it must be a problem with your router.

This is only a change of router, if it is still disconnected, it is a problem of the network, not a matter of the router.

This is a common problem of routers, generally routers will be used for more than 2 years, there will be drop-off problems one after another, is the life is up, you can first restore the factory settings, if it still doesn't work, you should replace the router.

There are several possibilities for old disconnection. One is the network cardThe second is the network cable. The third is the router. I guess most of it should be a matter of line. Redo the network cable header.!

If you try to change to another route, it won't drop, and if it doesn't fall, the route is not good, and if you use it, it's an external line.

You use 360 to fix vulnerabilities, clean up garbage, clean up traces, try, probably because other people's configurations are faster than yours, Johnny's internet speed

The problem that the router often drops off the Internet may be the unstable network of the broadband network itself, or the WAN port setting in the router settings, the default setting is on-demand connection, and you choose to connect it automatically.

You are using the wireless function of the router to access the Internet, and the wireless penetration ability of the general router is different, which is easy to cause disconnection. You can try to put your laptop in the room where you put the router to see if you can access the Internet properly, and if you can, try to move the router to the same location, preferably in the hallway!

Do you mean that everyone can't connect to the Internet or that the router can't connect to the server?

If the router can be connected to the operator's server normally, it can be that there is a computer with arp, if the router is not connected, then it may be a problem with the operator, there may be a problem with the network cable, or there may be a problem with the router itself, you can take the router to another place to try it, if the router is fine, you can test whether it is a problem with the network cable that is routed to the cat.

It may be that the performance of your router is not good, to be precise, the router's half-open connection is not enough, for example, if the LAN has bt**, it will be slow, change the route, or restrict others** things.

Log in to your router and set it up! If not. Call the telecom service ** and ask them to come and get it.

I think it's the problem of the network cable head, and our factory is doing about electronics.

When testing the function, it is because of the poor contact between the network cable head and the network cable.

Is it that the lower-end branches are automatically obtained after you use the WAN?,Maybe there is a conflict in the IP when the automatic acquisition is caused by disconnection.。

The port is restricted, and only one computer can access the Internet at the same time, and multiple computers cannot be accessed.

If you want to solve this problem, you can only use **, use one of your computers as the host (to dual network cards), and the other computers share the Internet through this host.

First of all, find out whether it is a line problem or a router problem, the line problem is solved by the network operator, the router problem is likely to be overheating and disconnected, and you can replace it.

The solution to the router's Internet disconnection is as follows:

1.There is a problem connecting your router or network cable. Recheck the device related to Internet access, reconnect the network cable, or turn the router or computer back on. Just try a few more times.

2.There is a piece of software on your computer that conflicts with the router, which is causing the problem. At this time, you can go to the repair, ask the master to help check and repair it.

This doesn't seem to have anything to do with the router.,It's probably still a problem with your network.。
