How do I connect to a corporate LAN network for help?

50 computers, 6M bandwidth, it is not a problem for office Internet access, and your LAN is also very slow, I estimate that the situation of your network is bad, the fundamental reason is that some computers are infected with viruses, constantly sending spam messages, blocking the network. A few poisoned computers will clog up your network. You should check it out thoroughly.

In addition, you also need to consider whether there is a problem with a computer network card or a router or switch. It is also recommended that you check it out. I have once encountered such a situation where the network card of one computer is broken, causing the entire network to go down.

A network of hundreds of computers.

In such cases, it is advisable to:

1.VLANs are used to divide subnets on the switch to shield broadcast storms.

2.Introduce a hardware firewall to control access to subnets while enabling QoS3It's best to bring in centralized virus and threat protection software.

4.MAC bindings can be used to quickly find and shield problematic terminals.

5.You can use the built-in network monitoring software of the device or purchased to understand the real-time network status and quickly find and solve the problem.

Landlord, you'd better draw a network topology map.

It is possible that this phenomenon is caused by broadcasting or ARP viruses.

Dizzy.. Hit most of the article.,A guy stopped.。。

Angry and don't fight.

Tell you to set up dual network cards.

The desktop primary NIC is connected to the external network.

Right-click on the second NIC - Advanced - Connection Sharing - Allow other users to tick which one IP will be automatically generated

This way the host is done.

Connect it to the laptop with a crossed cable.

Laptop IP settings.

Subnet gateways. This is from Inner Mongolia. To fill in your local area).

Host dial-up Internet access. In this way, both can be used.

This method is not easy to find the ISP provider.

Let's add some points.

To be honest, I'm a Netcom company.

Here's the solution:

1。If the company has other computers to access the Internet, find a switch and assign one to you.

2。If the company has an extra switch port, you can get on it by slitting the network cable from that port. The premise is that you don't have any other settings in the router...

3。The company doesn't have a computer with Internet access, so you can only pull a network cable or buy a wireless Internet from the wire.

4。Plug other network cables into your computer to see if you can access the Internet, if you can access the Internet, it means that you only need a network cable, you can refer to 1,2,3.

5。If you have a local connection to the company's network, you can access the Internet, dial in and let the router dial for you!!

A 150-meter network cable will definitely not work, at least I haven't seen a 180-meter cable.

It is recommended that you still use the fiber optic connection honestly at 150 meters or add a repeater to the twisted pair.

Put the switch near the telecom router, try it with a shorter cable, if it still doesn't work, then you need to consider the standard of the cable, whether to use a crossover cable, and many advanced routers and switches need to manually enable the port.

Slow to surf the internet? Could it be that someone is using a P2P tool, you can limit the traffic, or it could be an ARP attack, you know.

It is likely that when the network was first built, the administrator had allocated and limited your bandwidth, and some people may occupy a relatively large amount of bandwidth when surfing the Internet, which will cause others to surf the Internet very slowly.
