Are gateways the same as routers?
The gateway and the router are different; the gateway is mainly used to connect two different networks. At the same time, the gateway can also communicate with the hosts on both sides at the same time, while the router is a network layer device, usually Data is sent in packet units, and the sub-interface of the router has the function of dividing the broadcast domain.
#The operating environment of this article: Windows 7 system, Dell G3 computer.
1. Essential difference
The gateway is a device that is mainly used to connect two different networks. At the same time, the gateway can also communicate with the hosts on both sides at the same time. However, the hosts on both sides cannot communicate directly, and must communicate through the gateway. The work of the gateway is in the application layer.
Router is a network layer device that usually sends data in packet units. The sub-interface of the router has the function of dividing the broadcast domain, so when we use the switch to create a VLAN, we need to create a Layer 3 routing on the router.
2. Differences in usage
A gateway can be a router, switch or PC. Communication within the same network segment does not require the intervention of the gateway. Only when the host device communicates with a device other than the local network segment, all data packets need to be sent to the gateway device, and then forwarded or transmitted through the gateway device. There is routing processing and so on.
Router is a network layer system. Routers in the current market are generally divided into two categories, one is single-protocol router and the other is multi-protocol router. Routers can convert data formats and become necessary equipment for network interconnection between different protocols.
3. Functional differences
Gateways can be divided into transmission gateways and application gateways. Its function is to serve as the conversion task, which is essentially IP addresses from one network to other networks.
The main functions of a router are: connecting different networks and transmitting information. According to use, it can be divided into: access, enterprise level, backbone level, terabit, multi-WAN and 3G wireless.

Can the router be placed upside down?
Sep 22, 2023 pm 02:11 PM
Can. However, you need to pay attention to some issues: 1. Placing the router upside down may have a certain impact on heat dissipation, causing heat to accumulate at the bottom of the router, affecting the heat dissipation effect. Long-term overheating may reduce the performance of the router and adversely affect its lifespan. ; 2. Placing the router upside down may affect the operation and management of the device, and the indicator lights and interfaces may be blocked or inconvenient to operate; 3. Placing the router upside down may also have a certain impact on network security, and the default user name and password may cause This information is more susceptible to prying eyes.
What does router sn mean?
Oct 27, 2022 pm 05:21 PM
In routers, sn stands for "Serial Number", which means "serial number" and refers to the factory number of the router. The router serial number (SN) and physical address are both hardware identifiers, which are unique; the router will be under warranty only if the router's serial number is kept intact. The router serial number SN can be seen directly in the manual and on the back of the router.
What are the benefits of turning on ipv6 on the router 'Advantages of using the latest IPv6'
Feb 06, 2024 pm 05:34 PM
Students who know computers all know that if our computer wants to connect to the network, it must have an IP address. This IP address can be manually configured, such as 172.16.19.20; it can also be automatically obtained by the DHCP server of the computer network card, such as 192.168.1.100 etc. These IP addresses are what we often call IPV4 addresses, and the corresponding IPV6 is also a type of IP address. What is IPV6 IPV6 is a new IP address that emerged in response to the exhaustion of IPV4 address resources. Its full name is "Internet Protocol Version 6", and its Chinese name is the sixth generation of Internet Protocol. The number of IPv6 addresses is theoretically 2^128
How many lights on the router are normal? 'Recommended detailed explanation of the normal status of the router indicator lights'
Feb 06, 2024 pm 09:12 PM
The first light is on, indicating that the router is powered on. Which port is plugged in, the light of which port is on, and flashing means data is being transmitted. Wireless routers usually have three indicator lights: SYS, LAN and WAN. When the wireless router is powered on, the SYS light will light up. When the wireless router is connected to the network modem, the WAN light will light up. The LAN light corresponds to each interface of the wireless router. As long as the network cable is inserted into the corresponding interface, the corresponding LAN light will light up. 1. If it keeps flashing, it means it is transmitted by data, and the router settings should be normal. 2. If you have always been able to access the Internet, but you can't get online recently; it is probably a problem with the external line, that is, a problem with the operator (usually there is a problem with the line, causing the data signal to attenuate too much, although the line is good)
Which one is faster, gateway or router?
Jun 19, 2023 pm 03:06 PM
The difference between gateway WiFi and router WiFi is mainly reflected in three aspects: function, number of terminals that support Internet access, and WiFi signal coverage. Gateway WiFi is a combination of optical modem and router. It has more functions, but it supports fewer Internet devices and the WiFi signal coverage is not as good as router WiFi.
Why can't I ping the gateway? Why can't ping?
Mar 13, 2024 pm 03:40 PM
The network cannot ping, what's going on? In fact, this is a very common problem. It is mainly divided into two situations: pinging fails on the same network segment and pinging fails on different network segments. Let’s take a look at the details below. There are usually two reasons why the ping command cannot connect to the same network segment: one is an IP address that cannot be pinged in the same network segment, and the other is an IP address that cannot be pinged in a different network segment. These two situations have different solutions. First, let’s discuss the situation where ping fails within the same network segment. 1. Ping fails on the same network segment, and the result is "Unable to access the target host." The destination IP and source IP are on the same network segment, and the ping result is &l
