An access point may be built into your Ethernet router, or it may be a stand-alone unit. Each access point has a limited range, up to about 300 feet, or 100 meters. However, you can have more than one access point, and they can talk to each other. To let WiFi computers within range access the Internet, at least one access point has to connect to your Internet modem, usually with an Ethernet cable.\nTo make your Mac a WiFi access point, follow these steps on the computer that has the Internet connection: Select System Preferences from the Apple menu, click the Sharing icon, and then click the Internet button. From the Share Your Connection From popup menu, select the way this computer is connected to the Internet: typically Ethernet, Modem, or Bluetooth.\nIn the To Computers Using section, select the AirPort check box. Click the AirPort Options button and assign your new network a name. Turn on encryption if you like, enter a password, and click OK.

As the user moves out of the range of one access point, another access point automatically picks up the user and takes over without interrupting the user’s network service.\nTo set up two or more access points for roaming, you must carefully place the WAPs so that all areas of the office or building that are being networked are in range of at least one of the WAPs. Then, just make sure that all the computers and access points use the same SSID and channel.\nTwo or more access points joined for the purposes of roaming, along with all the wireless computers connected to any of the access points, form what’s called an Extended Service Set, or ESS. The access points in the ESS are usually connected to a wired network.\nOne of the current limitations of roaming is that each access point in an ESS must be on the same TCP/IP subnet. That way, a computer that roams from one access point to another within the ESS retains the same IP address. If the access points had a different subnet, a roaming computer would have to change IP addresses when it moved from one access point to another.\nWireless bridging\nAnother use for wireless access points is to bridge separate subnets that can’t easily be connected by cable. For example, suppose that you have two office buildings that are only about 50 feet apart. To run cable from one building to the other, you’d have to bury conduit — a potentially expensive job.\nBecause the buildings are so close, though, you can probably connect them with a pair of wireless access points that function as a wireless bridge between the two networks. Connect one of the access points to the first network and the other access point to the second network. Then, configure both access points to use the same SSID and channel.\nAd-hoc networks\nA wireless access point is not necessary to set up a wireless network. Any time two or more wireless devices come within range of each other, they can link up to form an ad-hoc network. For example, if you and a few of your friends all have notebook computers with 802.11b/g wireless network adapters, you can meet anywhere and form an ad-hoc network.\nAll of the computers within range of each other in an ad-hoc network are called an Independent Basic Service Set, or IBSS.","item_vector":null},"titleHighlight":null,"descriptionHighlights":null,"headers":null},{"objectType":"article","id":185109,"data":{"title":"Network Basics: Configuring Internet Access","slug":"network-basics-configuring-internet-access","update_time":"2016-03-26T19:54:58+00:00","object_type":"article","image":null,"breadcrumbs":[{"name":"Technology","slug":"technology","categoryId":33512},{"name":"Information Technology","slug":"information-technology","categoryId":33572},{"name":"Networking","slug":"networking","categoryId":33581},{"name":"General Networking","slug":"general-networking","categoryId":33585}],"description":"To enable the network users to access the Internet, you need to make sure that the TCP/IP configuration settings on each client computer are set correctly. If you have a high-speed Internet connection, such as T1, DSL, cable, or ISDN, connected to the Internet via a router and your network uses DHCP for automatic TCP/IP configuration, you may not need to do anything special to get your clients connected to the Internet.\nConfiguring clients for DHCP\nThe easiest way to configure client computers to access the Internet via a shared high-speed connection is to use DHCP. DHCP automatically distributes the detailed TCP/IP configuration information to each client. Then, if your configuration changes, all you have to do is change the DHCP server’s configuration. You don’t have to manually change each client. Plus, the DHCP server avoids common manual configuration errors.\nBefore you configure the clients to use DHCP, you should first set up the DHCP server. The DHCP server’s configuration should include:\n\n A scope that specifies the range of IP addresses and the subnet mask to be distributed to client computers.\n \n The IP address of the router that should be used as the default gateway for client computers to reach the Internet.\n \n The IP addresses of the DNS servers that clients should use.\n \n\nNote that DHCP can be provided either by a server computer or by an intelligent router that has built-in DHCP.\nAfter the DHCP server is configured, setting up Windows clients to use it is a snap. Just follow these steps for Windows 7:\n\n Open the Control Panel and click View Network Status and Tasks.\n \n Click Change Adapter Settings.\n \n Right-click the LAN connection icon and choose Properties.\nThis brings up the Local Area Connection Properties dialog box.\n\n \n Select Internet Protocol Version 4 (TCP/IPv4) from the list of items used by the connection and then click the Properties button.\nThis displays the Internet Protocol Version 4 (TCP/IP) Properties dialog box.\n\n \n Make sure that both the Obtain An IP Address Automatically and Obtain DNS Server Address Automatically options are selected.\nThese options enable DHCP for the client.\n \n Click OK to return to the Local Area Connection Properties dialog box and then click OK again.\n \n\nThat’s all there is to it. The computer is now configured to use DHCP. You should check to make sure that every computer on your network is configured for DHCP.\nIf your network doesn’t have a DHCP server, you’ll have to configure the TCP/IP configuration manually for each computer. Start by deciding the IP address that you want to assign to each computer. Then, follow the preceding procedure on every computer. When you get to Step 4, enter the computer’s IP address as well as the IP address of the default gateway (your Internet router) and the IP addresses of your DNS servers.\nFrankly, setting up a DHCP server is a lot easier than manually configuring each computer’s TCP/IP information, unless your network has only two or three computers. So unless your network is tiny, get a DHCP server.","item_vector":null},"titleHighlight":null,"descriptionHighlights":null,"headers":null}]},"relatedArticlesStatus":"success"},"routeState":{"name":"Article4","path":"/article/technology/information-technology/networking/general-networking/configuring-a-wireless-access-point-200662/","hash":"","query":{},"params":{"category1":"technology","category2":"information-technology","category3":"networking","category4":"general-networking","article":"configuring-a-wireless-access-point-200662"},"fullPath":"/article/technology/information-technology/networking/general-networking/configuring-a-wireless-access-point-200662/","meta":{"routeType":"article","breadcrumbInfo":{"suffix":"Articles","baseRoute":"/category/articles"},"prerenderWithAsyncData":true},"from":{"name":null,"path":"/","hash":"","query":{},"params":{},"fullPath":"/","meta":{}}},"dropsState":{"submitEmailResponse":false,"status":"initial"},"sfmcState":{"status":"initial"},"profileState":{"auth":{},"userOptions":{},"status":"success"}}

The physical setup for a wireless access point is pretty simple: You take it out of the box, put it on a shelf or on top of a bookcase near a network jack and a power outlet, plug in the power cable, and plug in the network cable.

The software configuration for an access point is a little more involved, but still not very complicated. It's usually done via a Web interface. To get to the configuration page for the access point, you need to know the access point's IP address. Then, you just type that address into the address bar of a browser from any computer on the network.

Multifunction access points usually provide DHCP and NAT services for the networks and double as the network's gateway router. As a result, they typically have a private IP address that's at the beginning of one of the Internet's private IP address ranges, such as 192.168.0.1 or 10.0.0.1. Consult the documentation that came with the access point to find out more.

Basic configuration options

When you access the configuration page of your wireless access point on the Internet, you have the following configuration options that are related to the wireless access point functions of the device. Although these options are specific to this particular device, most access points have similar configuration options.

  • Enable/Disable: Enables or disables the device's wireless access point functions.
  • SSID: The Service Set Identifier used to identify the network. Most access points have well-known defaults. You can talk yourself into thinking that your network is more secure by changing the SSID from the default to something more obscure, but in reality, that only protects you from first-grade hackers. By the time most hackers get into the second grade, they learn that even the most obscure SSID is easy to get around. So leave the SSID at the default and apply better security measures.
  • Allow broadcast SSID to associate? Disables the access point's periodic broadcast of the SSID. Normally, the access point regularly broadcasts its SSID so that wireless devices that come within range can detect the network and join in. For a more secure network, you can disable this function. Then, a wireless client must already know the network's SSID in order to join the network.
  • Channel: Lets you select one of 11 channels on which to broadcast. All the access points and computers in the wireless network should use the same channel. If you find that your network is frequently losing connections, try switching to another channel. You may be experiencing interference from a cordless phone or other wireless device operating on the same channel.
  • WEP — Mandatory or Disable: Lets you use a security protocol called wired equivalent privacy.

DHCP configuration

You can configure most multifunction access points to operate as a DHCP server. For small networks, it's common for the access point to also be the DHCP server for the entire network. In that case, you need to configure the access point's DHCP server. To enable DHCP, you select the Enable option and then specify the other configuration options to use for the DHCP server.

Larger networks that have more demanding DHCP requirements are likely to have a separate DHCP server running on another computer. In that case, you can defer to the existing server by disabling the DHCP server in the access point.
