The computer has been disconnected since it was lightning.

Your situation is similar to mine.

At first, I didn't really know.

But after long-term research.

Usually to flash, it is estimated that it is a problem with the line, and it is estimated that the line has aged or broken somewhere.

Of course, it is also possible that the cat is broken.

But if it is flashing after lightning.

In general, it can be a problem with cats.

Poor quality cats can be easily hacked.

It is recommended to turn the cat off when the lightning is lightning.

My cat has been hacked.

Of course, it is not excluded that the signal is not good due to lightning and rainy days.

As for the server room, it is generally not a problem casually, and if something goes wrong, the whole person has a problem, and it can't be just you.

So the final conclusion is that your cat's problem is more likely.

I've been in the same situation, 3 possibilities. Motherboard damaged, network card, cat.

That's right, my computer was hacked once and even the cat was broken together, hehe....

Replace the cat and network card.

If it is an integrated network card, it is best to buy a separate network card, 30 yuan. Cats can be swapped with service providers.

Find a few points to solve this kind of problem.

1 Broadband line, is it too long to age, find the ** bureau to help you check the line.

2 You said that you were thundered, and they were all changed, but it is not necessarily good that you changed it, right? If you drop the connection so frequently, it may be your cat's problem, but not the network card. Cats are more prone to this problem, I just spent hundreds of dollars in a hurry, and I changed the route.

The memory of the route is important. Buy a good one.

Generally on these issues.

I think since you just changed the network card and the cat, the chance of them having problems is still relatively small.

Because it has been struck by lightning, it is very likely that the line has a burned part, resulting in poor network cable contact.

But let's be honest, the external terminals can rust, and your environment is too ......

The cat link light flashes, which means that there is a problem with the outside line, that is, the line from the Netcom splitter to your home, is there a bad contact.

Mobile phones and ipads are no problem, first of all, the home line problem is ruled out, then Zheng Stool needs to check whether the computer network card is working properly, and can not be solved, consider whether it is related to the router setting problem and the recently installed software or whether the system is in conflict with the Windows system, and if it cannot be solved, you can only ask professional maintenance personnel to check at home.

That's because you're using wifi.,The computer uses wifi is very unstable.,I'm using wifi myself and it's the same.,Although it doesn't drop the line.,But the old card.。 You do this, plug in the Internet cable when using the computer, and you're good to go. You look at your network, 4mwifi is not as good as 2m plugged in the network cable, I don't know the principle of Gu Fan Jingxun body, but this trick is very effective.

If it still doesn't work, change to a better network.

Step 1: Open IE - Tools - Internet Options - Connection - Settings - Dial-up Settings (fill in the account and password) OK - click "Broadband Connection (Default)" - select below"Always dial the default connection"。

Step 3: Right-click on the online neighbor - local connection - properties - Internet protocol - select separately"Use the IP address below"、"Use the DNS service address below"- Fill in the IP address in step 2.

Reboot. Then you can find that your computer is automatically connected to the Internet as soon as you turn it on.

Is it a problem with the network?

There are many reasons for this, and my suggestion is this: you first buy a section of **line to change the **line in your home! It may be that the line is not working, resulting in network disconnection, and then the route can be set again!

After setting it up, try to see if there is any phenomenon of disconnection, if there is still a phenomenon! Look at the problem of the network card!

After the notebook is struck by lightning, the common faults are: first, the network card is not good to make the spine tease, second, the motherboard does not supply power, third, Nanqiao pointed out that the BGA chip of the main control equipment outside the Sakura Oak equipment is burned out, and it is recommended that you send it for repair and testing.

I'll help you in Beijing.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

The network is unstable, so it is recommended that you take all the excuses from scratch. Set up the router from the new settings. In order to avoid wireless routing and other people's rubbing the network.

Just unplug the network cable for a while!

Step 1: Open IE - Tools - Internet Options - Connection - Settings - Dial-up Settings (fill in the account and password) OK - click "Broadband Connection (Default)" - select below"Always dial the default connection"。Step 2:

Start-Run-Fill cmd, press Enter - fill in ipconfig all, press Enter--- you can know the current IP address. Step 3: Right-click on the online neighbor - local connection - properties - Internet protocol - select separately"Use the IP address below"、"Use the DNS service address below"- Fill in the IP address in step 2.

Reboot. Then you can find that your computer is automatically connected to the Internet as soon as you turn it on.

Please check whether the router is too old, the router is too old, the temperature is easy to be high, it is in the self-protection mechanism, and the router will automatically restart.

Check your router first, and if it doesn't work, refresh the port.

There are many reasons for this, sometimes the network is unstable, the network cable is aging, the connector is oxidized, etc., what is the Internet used? Cat? Routing?

You can try the cat or router first, is it very hot, if it's hot, it's their reason, the heat dissipation hasn't kept up, put the cat or router, put it in a well-ventilated place, the space is tight, you can order something below, leaving enough space to dissipate heat.

If you fix the thread, it won't fall off!
