Effect of NIC, router, and DNS settings on network speed

Does Nic, router, and DNS settings affect the network speed? Yes, wrong or incorrect settings can indeed change your bandwidth to a narrow band. In many cases, it is not a problem with the communication operator, but a fault in your hardware and software settings.

The NIC may affect the network speed. from the Internet to the home port, the speed is determined by the network bandwidth, and the internal data transmission of the computer depends on the baud rate of the NIC, it is considered that there is no impact, mainly because the computer is currently installed with the 10/100 adaptive network card, few people install the KM network card and more advanced network card, because there is no comparison, therefore, the relationship between the network card and the network speed is not very large. An independent network card is better than an integrated network card and occupies less system resources without interrupting the network card. We recommend that you buy an independent network card to install it and shield the integrated network card on the motherboard. D-Link DGE-660TD 400 yuan.

Nic settings will also directly affect the speed of the workstation

The network adapter can work in full-duplex and half-duplex modes. When the server, switch, and workstation do not work properly, such as the server or workstation Nic is set to full-duplex, when the switch and hub are both in the half-duplex status, a large number of collision frames and some incorrect FCS verification frames will be generated, and the access speed will become very slow, it may take 5 to 5 minutes to copy a 20 mb file from the server ~ 10 minutes.

When both ends of the network connection are in full duplex mode, the performance is the highest, and the network adapter on the PC is easily set to half duplex mode by the user unintentionally or intentionally through the software. Monitoring the connection speed is important to check whether the duplex settings of the two ports match. Experts suggest using a software named Multi-router Traffic Grapher to monitor the performance of network connections to ensure that full duplex settings are enabled on both ends.

Other factors affecting network speed: vswitches and vrouters

Nic has some influence on the network speed, but the effect may not be very big. We don't feel it. Factors that affect the network speed, except the network card, are more likely to be reflected by other factors, such as the impact of switches and routers on the network speed.

The configuration of vswitches and routes is also an important factor in network performance.

Generally, if a broadcast packet of a network accounts for more than 30% of all communication packets, the network performance will be significantly reduced. Currently, almost all vswitches provide VLAN support. Although it is a little difficult to set a VLAN, it is recommended that the network management can configure a VLAN because of its significant performance improvement.

Vro is very powerful and has excellent speed. Therefore, if possible, an enterprise should try its best to purchase a router that meets the enterprise's requirements. Generally, the routing protocol is the PPP that connects to the ISP. There is not much improvement in the configuration. Some routers support ACL access control, and some traffic can be blocked through reasonable configuration, increasing the network bandwidth.

Have you noticed the router and DNS settings? Do not think that these things have nothing to do with your network speed. In fact, if you set them properly, it will increase your network speed to a certain extent.
