Frequenty Asked Questions (FAQs) in Wireless Networking
Why Build a Wireless Home Network?
A network (either wired or wireless) increases the usefulness of your home computers. Wireless home networks offer even more benefits than wired ones.
What Hardware is Required to Build a Wireless Network?
Strictly speaking, no hardware other than wireless adapters is required to build a small wireless LAN (WLAN).
How Many Computers Can Share One Wi-Fi Network?
The exact number of devices that can connect and effectively share a WiFi varies but is probably larger than you think.
Can a Wireless LAN Share Dial-up Internet Service?
Try either of these two approaches for setting up shared dial-up Internet access on a home WLAN.
Can Two Routers Be Used on the Same Home Network?
Installing two routers on the same home network can be useful when building a hybrid wired and wireless network or generally expanding the existing capability.
Is 5 GHz Wi-Fi Computer Hardware Better than 2.4 GHz?
Mainstream wireless network equipment used in routers and computers generally signals in either a 2.4 GHz range or a 5 GHz range. However, just because it carries a bigger number, 5 GHz hardware is not necessarily better than 2.4 GHz hardware.
Is It Legal to Use Open Access Wi-Fi Internet Connections?
Wi-Fi technology simplifies the sharing of network connections between multiple computers and people. However, using someone else's Internet service may not be legal even if it is open access.
What is WiFi Ad-Hoc Mode?
On wireless computer networks, ad-hoc mode is a method for wireless devices to communicate with each other peer-to-peer.
What is WiFi Infrastructure Mode?
In wireless networking, infrastructure mode bridges a WLAN with a wired Ethernet LAN and allows Wi-Fi networks to support more clients with greater reach.
Are 802.11b and 802.11g Compatible?
802.11b and 802.11g are both popular standards for Wi-Fi home networking. Can 802.11b and 802.11g gear be mixed on a wireless network, or are they incompatible?
How Can I Get 300 Mbps Speed on My 802.11n Network?
802.11n network equipment supports up to 300 Mbps of rated bandwidth under certain conditions as described here. Unfortunately, sometimes an 802.11n network will operate at much lower speeds.
What Are the Limitations of WiFi Ad-Hoc Mode Networking?
WiFi ad-hoc mode networking allows devices to connect wirelessly without the need for a central access point or router. However, ad-hoc WiFi also suffers from some key limitations as described here.
Do Wireless Routers Support Hybrid Networks?
Many (but not all) wireless routers support hybrid local area networks containing a mix of wired Ethernet and WiFi clients.
What is Wi-Fi Bridging Mode?
In Wi-Fi networking, bridging mode allows two or more wireless access points (APs) to communicate with each for the purpose of joining multiple LANs.
Are Wireless Networks a Health Hazard?
Can prolonged exposure to wireless network devices cause memory loss or other brain damage?
How Does Wi-Fi Use Affect Computer Battery Life?
The Wi-Fi network protocol requires electric power to operate the radios used to send and receive data. Using Wi-Fi on a computer or handheld device can significantly increase its power consumption (shortening battery life).
Can Wi-Fi Be Turned Off for Computers and Routers?
To save power and somewhat improve your network’s security, you should consider turning off the Wi-Fi radios on both the router and all computers when not using wireless connections.
What Is Wireless Spread Spectrum Communication?
A set of techniques that have been used in radio communications for decades, spread spectrum is also employed in modern Wi-Fi networking to enhance reliability, increase bandwidth and/or improve security of wireless computer connections.
What Is Wibree?
Wibree is not much related to Wi-Fi the name notwithstanding; instead, Wibree is a short-range wireless technology more comparable to Bluetooth.
