Access Point Lan

[Kemal Allan]

Incomputer networking, a wireless access point, or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a router or router, but, in a wireless router, it can also be an integral component of the networking devices itself. An WAP & AP is differentiated from a Wi-FiMi-Fi)hotspot, which is a can be a physical location or digital location where Wi-Fi or WAP access is available.[1][2]

Although WAP has been used correctly to describe an access point in mobile telephony phones, which are managed by an Internet service provider and can be modified while using a SIM card or ESIM which acts as a modem in mobile phone device. WAP refers to Wireless Access Point protocol in digital cellular networks in a mobile telephony device.

An AP connects directly to a wired local[3] area network, typically Ethernet, and the AP then provides wireless connections using wireless LAN technology, typically Wi-Fi, for other devices to use that wired connection. APs support the connection of multiple wireless devices through their one wired connection.

There are many wireless data standards that have been introduced for wireless access point and wireless router technology. New standards have been created to accommodate the increasing need for faster wireless connections. Access points can provide backward compatibility with older Wi-Fi protocols as many devices were manufactured for use with older standards.[3]

Some people confuse wireless access points with wireless ad hoc networks. An ad hoc network uses a connection between two or more devices without using a wireless access point; the devices communicate directly. Because setup is easy and does not require an access point, an ad hoc network is used in situations such as a quick data exchange or a multiplayer video game. Due to its peer-to-peer layout, ad hoc Wi-Fi connections are similar to connections available using Bluetooth.

Ad hoc connections are generally not recommended for a permanent installation.[1] Internet access via ad hoc networks, using features like Windows' Internet Connection Sharing or dedicated software such as WiFi Direct Access Point, may work well with a small number of devices that are close to each other, but ad hoc networks do not scale well. Internet traffic will converge to the nodes with direct internet connection, potentially congesting these nodes. For internet-enabled nodes, access points have a clear advantage, with the possibility of having a wired LAN.

Most jurisdictions have only a limited number of frequencies legally available for use by wireless networks. Usually, adjacent APs will use different frequencies (channels) to communicate with their clients in order to avoid interference between the two nearby systems. Wireless devices can "listen" for data traffic on other frequencies, and can rapidly switch from one frequency to another to achieve better reception. However, the limited number of frequencies becomes problematic in crowded downtown areas with tall buildings using multiple APs. In such an environment, signal overlap becomes an issue causing interference, which results in signal degradation and data errors.[6]

Wireless networking lags wired networking in terms of increasing bandwidth and throughput. While (as of 2013) high-density 256-QAM modulation, 3-antenna wireless devices for the consumer market can reach sustained real-world speeds of some 240 Mbit/s at 13 m behind two standing walls (NLOS) depending on their nature or 360 Mbit/s at 10 m line of sight or 380 Mbit/s at 2 m line of sight (IEEE 802.11ac) or 20 to 25 Mbit/s at 2 m line of sight (IEEE 802.11g), wired hardware of similar cost reaches closer to 1000 Mbit/s up to specified distance of 100 m with twisted-pair cabling in optimal conditions (Category 5 (known as Cat-5) or better cabling with Gigabit Ethernet). One impediment to increasing the speed of wireless communications comes from Wi-Fi's use of a shared communications medium: Thus, two stations in infrastructure mode that are communicating with each other even over the same AP must have each and every frame transmitted twice: from the sender to the AP, then from the AP to the receiver. This approximately halves the effective bandwidth, so an AP is only able to use somewhat less than half the actual over-the-air rate for data throughput. Thus a typical 54 Mbit/s wireless connection actually carries TCP/IP data at 20 to 25 Mbit/s. Users of legacy wired networks expect faster speeds, and people using wireless connections keenly want to see the wireless networks catch up.

By 2012, 802.11n based access points and client devices have already taken a fair share of the marketplace and with the finalization of the 802.11n standard in 2009 inherent problems integrating products from different vendors are less prevalent.

Wireless access has special security considerations. Many wired networks base the security on physical access control, trusting all the users on the local network, but if wireless access points are connected to the network, anybody within range of the AP (which typically extends farther than the intended area) can attach to the network.

The most common solution is wireless traffic encryption. Modern access points come with built-in encryption. The first generation encryption scheme, WEP, proved easy to crack; the second and third generation schemes, WPA and WPA2, are considered secure[7] if a strong enough password or passphrase is used.

Opinions about wireless network security vary widely. For example, in a 2008 article for Wired magazine, Bruce Schneier asserted the net benefits of open Wi-Fi without passwords outweigh the risks,[8] a position supported in 2014 by Peter Eckersley of the Electronic Frontier Foundation.[9] The opposite position was taken by Nick Mediati in an article for PC World, in which he advocates that every wireless access point should be protected with a password.[10]

A wireless access point (WAP) is a networking device that allows wireless-capable devices to connect to a wired network. It is simpler and easier to install WAPs to connect all the computers or devices in your network than to use wires and cables.

You can also use a WAP or mesh extenders to extend the signal range and strength of your wireless network to provide complete wireless coverage and get rid of "dead spots," especially in larger office spaces or buildings. Additionally, you can configure the settings of your WAPs using a single device.

In this configuration, an access point is connected directly to a wired LAN, providing a connection point for wireless users. If more than one access point is connected to the LAN, users can roam from one area of a facility to another without losing their network connection.

The repeater forwards traffic between wireless users and the wired network by sending data to either another repeater or an access point that is connected to the wired network. The data is sent through the route that provides the best performance for the client.

Access points can be configured as root or non-root bridges to join multiple networks. An access point in this role will establish a wireless link with a non-root bridge. Traffic is then passed over the wireless link to the wired network.

For example, if your business needs wireless connectivity for a group of network printers, you can connect the printers to a hub or a switch, connect the hub or switch to the access point Ethernet port, and configure the access point as a workgroup bridge. The workgroup bridge will then "associate" to an access point on your network.

In an all-wireless network, an access point acts as a standalone root unit. It is not attached to a wired LAN. Instead, the access point functions as a hub that links all stations together. It serves as the focal point for communications, increasing the communication range of wireless users.

WAPs are a more convenient, secure, and cost-efficient alternative to using wires and cables to connect every computer or device in your network. And using WAPs to set up a wireless network can provide many advantages and benefits for your small business.

For one, a wireless network is more convenient to access. Adding new users is a lot less complicated, too. And you can easily provide Internet access to guest users by giving them a password to access your wireless network securely.

I've received great help from this community in setting up an ancient netgear router as an AP for devices on the top floor of my house (see -Modems-Routers/DGN3500-as-secondary-router-access-point-bridge-... ).

Note that is disables "Internet Setup". My guess is that it ignores that setting. But in your case, this is an ancient DSL modem/router made before the time when they expected people to play these ticks with hardware.
