Question, I m an internet caf and the internet is very slow.

I've been in all three of these situations.

1. Router problem, restart routing problem solved.

2. The network cable asks a problem, and the short circuit is caused by the non-standard production of the network cable, just find the problematic network cable and redo it.

3. DNS problem, due to DNS error, the network speed is slow, you can try it with another DNS.

It may be a wiring problem, so take a closer look at the wiring.

You'd better check the quality of the line to see if the network cable has jumped the wrong line.

I have used a lot of routes, often find that the network has an inexplicable failure, look around, and finally find that it is a routing problem, if you are possible, you replace it, confirm that it is a route! You can ping routes, but if there is a packet drop or the ping fails, it is a routing problem.

It's all copy-pasting something. Crashed router problem Let's change the brand. With Cisco's.

As a netizen, I'm used to it, and now all I should do is shout....Management.

Attacked? That should be an ARP attack.

If you have a diskless system, bind it to a MAC with a router

What age do you still go to Internet cafes!! Buy your own machine, DIY one, I'll configure it for you.

cpu amd 2 250

Motherboard: MSI 785GM E65 or GIGABYTE GA-MA785GPMT-UD2H

WD 500 g blue disk.

ADATA 2G DDR3 1333

Great Wall Silent Master 300SD ATX-300SD This is the configuration of my home.

The team is good, or with the Gigabyte GA-MA785GPMT-UD2H, it is recommended to use the Destroyer case.

LCD with Samsung P 2250W 22 inch handsome. Thank you.

This is because they are afraid that if one person's machine occupies most of the Internet speed, then others will be very stuck in the Internet, and they generally limit the speed on the switch, or use their paid software to limit it.

If you know their password, you can set the machine to not work. If you don't know, there's no good way to do it.,Their speed limit is generally for Mac.。。

You can change the MAC address, machine name, workgroup to try, but I don't estimate the chance of success is high...

Report an old !! Or take a knife.

Reason 1: The fault of local viruses and Trojans.

This is the answer that many netizens think of for the first time. Yes, infection with certain viruses and Trojans can indeed cause slow internet speeds. However, how many netizens will verify it?

The first step of verification: use anti-disease and high-rolling software to check the virus comprehensively. This is the easiest way to do this, but it doesn't always work out.

Verification Step 2: Observe the CPU operation and network conditions. If the CPU is running non-stop for no reason, and the network connection is constant, it is possible that a virus Trojan is the cause.

Verify Step 3: Dos commands. Ping under DOS to see how responsive the network is.

Cause 2: Server issues.

Internet access has to go through many services to reach the destination. Therefore, the server directly affects the user's network speed. Network congestion can also slow down internet speeds.

Cause 3: Network viruses targeting the server.

Network viruses that target servers tend to slow down or bring down networks. However, it is not the user's business to solve this problem.

Cause 4: Local system issues.

The system takes a long time and often fails. If the internet speed slows down suddenly long after the device is turned on, you may want to restart it to see if it solves the problem. Sometimes, it is even necessary to reinstall the system to solve the problem.

Reason 5: The CPU is busy working.

The CPU is busy working and will directly affect the network and computer speed. So it's necessary to check how your CPU is working when the internet is slow.

The total bandwidth is limited, and the more people who use it, the slower it will be.

For example, 100 people and 10,000 people on the road have to travel at different speeds.

Because the network cable of the Internet café is a network cable for several machines.
