Wireless access points are created by installing wireless routers. These routers are providing the opportunity for other devices to get wireless access to a network and or internet.
Wireless routers are required to have a wireless network connection. The stronger the wireless signal the further the signal will reach. Although the network can be seen by others within it's signal range, for security reasons your network cannot be accessed without a network key. Specifically a N rated wireless router has a powerful signal. G routers are much less powerful. For any router to work you need to connect a wireless receiver to the computer you want on the network.
If I understand your question, using the Belkin as a repeater, the answer is no.
Yes. most wifi routers have multiple ports on the back to hook up a wired network along side the wireless.
wireless access points, wireless network interface cards (NICs) and routers.
Many Wireless routers and switches have few inbuilt switching ports capable of connecting Wired computers to Wireless Computers on the same network to connect wired Computers also alongwith. (Not necessarily every every wireless router will be having switching ports)
Wireless network adapters (also known as wireless NICs or wireless network cards) are required for each device on a wireless network. Some newer laptop computers incorporate wireless adapters as a built-in feature of the system. Separate add-on adapters must be purchased for most computers, however. Popular wireless network adapters for PCs exist in the form of a PCMCIA "credit card." Macintosh computers use the distinctive AirPort card. USB wireless adapters that do not resemble cards also exist. Strictly speaking, no wireless hardware other than adapters is required to build a small wireless LAN (WLAN). However, to increase the performance of a WLAN, accommodate more computers, and increase the network's range, wireless access points and/or wireless routers can be deployed. Wireless routers function comparably to traditional routers for wired networks. One generally deploys wireless routers when building an all-wireless network from the ground up. An alternative to routers, access points allow wireless networks to join an existing wired network. One typically deploys access points when growing a network that already has a wired switch or router installed. In home networking, a single access point (or router) possesses sufficient range to span most homes. Businesses in office buildings often must deploy multiple access points and/or routers. Access points and routers often utilize a wireless antenna that significantly increase the communication range of the wireless radio signal. These antennas are optional and removable on most equipment. It's also possible to mount antennas on wireless clients to increase the range of wireless adapters. This is common practice for wardrivers, but add-on antennas are generally not required in typical home or business networks.
Make sure that you are using a correct ip address. IP address for your router you can find in network properties of your network adapter when you are connected to the wireless network.
Wireless N routers have better range and much better transfer speeds than G routers.
Do you meant a wireless booster? If yes, you can connect the LAN cable from the modem to the wireless booster so there will be 2 SSID those can be connected to your network.
The Cisco Wireless Network works by making all of the computers connect to the internet through the same router. Most Cisco routers have the wireless connect by using a password so others can not steal the bandwidth.
A WHR-G54S Buffalo device is a wireless router. Wireless routers are used by many people in home to establish a wireless network connection to the internet.
