Problems with wireless routers and wireless APs 50

Functionally differentiated.

Wireless AP: AP is the abbreviation of Access Point, generally translated as "wireless access node", which mainly provides wireless workstation access to the wired LAN and from the wired LAN to the wireless workstation, and the wireless workstations within the coverage of the access point can communicate with each other through it. Generally speaking, wireless AP is a bridge between wireless and wired networks.

Since the coverage area of the wireless AP is a circular area that spreads outward, the wireless AP should be placed in the center of the wireless network as much as possible, and the straight-line distance between each wireless client and the wireless AP should not exceed 30 meters to avoid communication failure caused by excessive communication signal attenuation.

Wireless router: A wireless router is a combination of a simple AP and a broadband router. With the help of the router function, it can realize the Internet connection sharing in the home wireless network, realize the wireless sharing access of ADSL and cell broadband, in addition, the wireless router can assign the terminals that carry out wireless and wired connection through it to a subnet, so that the various devices in the subnet exchange data is very convenient.

It can be said that a wireless router is a collection of APs, routing functions, and switches, and supports wired and wireless networks to form the same subnet and directly connect to the modem. A wireless AP is equivalent to a wireless switch, which is connected to a wired switch or router, and the IP is allocated from the router for the wireless network card connected to it

Therefore, the wireless AP can be connected to the wired router, and then send out a wireless Internet signal, so that our notebook, with wifi Internet access function and other devices can access the Internet through the combination of wireless AP and router, but there is also a premise that the router is connected to the Internet service through the cat, it is recommended that you buy a wireless router as well! More stable!

A wireless AP is a wireless terminal, which is lower than a wireless router. You can connect the wireless AP from the router, as long as the cat and router are on, the mobile phone can access the Internet through the AP. This has nothing to do with whether you can turn on the computer.

You can also directly change the existing line from wireless router, then you don't need wireless AP.

The differences between wireless APs and wireless routers are as follows:

1) The application is different:

Wireless APs are used in large companies, which need a large number of wireless access nodes to achieve large-area network coverage, and all access terminals belong to the same network, which is also convenient for the company's network administrator to easily implement network control and management.

Wireless routers are generally used in home and SOHO environment networks, and in this case, the coverage area and user users are generally not large, and only one wireless AP is sufficient. Wireless routers can realize the access of ADSL network and convert them into wireless signals at the same time, which is a more affordable and convenient choice than buying a router and a wireless AP.

2) The functions are different:

Wireless AP: The full name of AP is AccessPoint, and its function is to convert a wired network into a wireless network. Imaged point of view, wireless AP is the bridge between wireless network and wired network.

The signal range is spherical, and it is best to put it in a relatively high place when building, which can increase the coverage, and the wireless AP is a wireless switch, which is connected to a wired switch or router, and the wireless terminal accessed is the same subnet as the original network.

Wireless router: It is a wireless AP with routing function, which is connected to the ADSL broadband line, realizes automatic dial-up access to the network through the router function, and establishes an independent wireless home networking through the wireless function.

3) The connection method is different.

Wireless APs cannot be connected to ADSLmode, and a switch, hub, or router must be used as an intermediary. The wireless router has a broadband dial-up function, which can be directly connected to ADSLMODEM to dial-up the Internet to achieve wireless coverage.

Different concepts: First of all, the concept is different, wherein, AP is an access point of a wireless network, commonly known as a "hotspot", which can only be connected to the local area network, and has no Internet function, but only an intranet connection function. It is connected to other network devices through wired spikes, and then it transmits wireless signals by itself, so that other computers can access other networks through it, and the maximum coverage distance of general wireless AP can reach 500 meters.

A router is a router with wireless coverage that is used for users to surf the Internet. The wireless router can be regarded as a device, which can connect the broadband network signal from the wall of the home to the nearby wireless network equipment through the antenna, which can be connected to the Internet and the local area network.

Different functions: AP is the bridge of communication between the wireless network and the wired network, because the coverage of the wireless AP spreads in the circular area, so the wireless AP should be placed in the center of the wireless network as much as possible, so that the wireless client is within the signal radiation range of the wireless AP, it is equivalent to a wireless switch. The router is a combination of simple AP and broadband router, which can realize the sharing of Internet connection in the home wireless network, realize the wireless sharing access of ADSL and cell broadband, and also realize the wireless LAN to facilitate data exchange.

Different applications: APs are used in many places that require large-area coverage, such as hotels, office buildings, banquet halls, etc., and all APs are connected to independent wireless LAN firewalls through Ethernet. Wireless routers are used more in a small area of home coverage, and in the case of a small range and several users, wireless routing is easier to manage and cheaper.

The connection mode is different: APs cannot be directly connected to ADSL modem, and a switch or route server must be added when using it. However, most wireless routers have broadband dial-up capabilities, so they can directly connect with ADSL modem for broadband sharing.

The cost is different: there is still a difference between AP and wireless router, generally speaking, the number of routers needed for wireless coverage in a large area is much more than that of AP, that is, the router has more equipment when forming a wireless LAN, which is not easy to maintain. Therefore, a lot of large-area coverage uses high-power wireless APs.

Wireless APs and wireless routers are different in connection mode and function application.

Wireless APs are used more in larger companies and require a large area of network access to the same network for easy control and management. Wireless is suitable for use in the home, generally speaking, the coverage area is not large, and this can also realize ADSL access, which can be converted into a wireless signal.

The function of the wireless AP is that it can be converted into a wireless network, which is a bridge between wireless and wired. The wireless router has the function of wireless AP, which can be connected to ADSL broadband, and can also establish an independent home network.

The wireless AP cannot be connected to ADSLMODE, and the switch must be used as an intermediary. Wireless routers have their own dial-up function, which is directly connected to ADSLMODEM and also achieves wireless coverage.

Difference Between Wireless AP and Wireless Router:

1.Functional differences:

The function of wireless AP is to convert the wired network from the AC product to the wireless network, and the popular saying and understanding is: wireless AP is a bridge connecting the wired network and the wireless network.

Wireless router is a combination of AP and broadband router, it can realize the sharing of Internet connection in the home wireless network with the help of routing function, and can also understand the wireless router as a **device, the broadband network signal received from the wall at home through the antenna** to the nearby wireless network equipment (laptops, mobile phones that support wifi and all devices with wifi function), that is, the wired network can be directly converted into a wireless network product.

2.Differences in application scenarios:

Wireless AP is generally used in the construction of medium and large wireless networks, and a certain number of wireless APs are used with AC products to build a large wireless network coverage, and the use scenarios are generally large shopping malls, supermarkets, scenic spots, hotels, corporate offices, etc.

Wireless routers are generally used in the construction of small wireless networks, which can work independently and do not require the cooperation of AC and other products.

3.Differences in performance:

Wireless APs can be used with AC products for centralized management, which can centrally manage thousands of wireless APs and realize roaming functions, so that the wireless network covers a wider area under the condition of fully ensuring that the network does not drop.

Wireless routers cannot be centrally managed, need to be configured separately, the configuration work is cumbersome, and roaming function cannot be carried out, the wireless network coverage area is limited and the network is prone to disconnection.

4.Differences in advanced features:

Wireless APs work with AC products to roam wireless networks, making wireless network connections more secure. Wireless APs can be used with AC products to optimize radio frequency and other functions, making wireless networks faster and more stable.
