Routers, or routers as they are also called, are network communication devices. They redirect data packets in networks, analyze information flows, determine the subscriber's address, and choose the best route. It is advisable to buy a used Wi-Fi router if you need to connect several networks with different IP addresses and provide Internet access. Industrial routers support large networks, while household routers support several dozen devices. The price of a used router is much lower than a new one.
Characteristics of routers
The main task of a router is to provide communication between devices and Internet connection. There are wired and wireless models. Wired ones distribute the Internet via a cable, while wireless ones are connected via Wi-Fi. The easiest option is to buy a used Wi-Fi access point.
Routers differ from modems in that they combine switch functionality and analytical capabilities. They can build local networks, change data packaging, encrypt, and monitor traffic.
The main characteristics of routers:
- Supported protocols
- Interfaces
- Overall performance
- Antenna design
- VPN tunnel support
- Frequency of Wi-Fi operation
- LAN port speed
- Wi-Fi speed
Most models support standard protocols such as IP, OSI, IPX, AppleTalk, etc., as well as routing protocols such as RIP, OSPF, BGP, and others.
Interfaces:
- 1 x Gigabit Ethernet (10/100/1000 Mbps)
- 4 x Fast Ethernet (10/100 Mbps)
- 5-10 x Gigabit Ethernet
- 1 x SFP (Mini-GBIC)
The overall performance of the router depends on the type of processor and supported protocols. For example, an ASUS BU or Cisco BU router can have high performance for the corporate segment.
According to the design of antennas, routers can be equipped with external or built-in antennas. The antenna power is measured in dBi.
VPN tunnels are an additional feature for data encryption and remote network management. For example, the D-Link BU router may have this option.
Wi-Fi operates at 2.4 GHz or 5 GHz. The former is more stable but overloaded; the latter has better quality but worse interference.
LAN ports allow you to connect devices via cable. For home use, 100 Mbps is enough, and for business, it is better to choose models with 1000 Mbps.
Wi-Fi speed is another important parameter. It starts from 300 Mbps and can reach 1733 Mbps and more.
Among the well-known brands, the best performers are: Cisco, Aruba, D-Link, Extreme, Fortinet, Mikrotik, ZyXel.
