Wi-Fi networking gives you the freedom to add mobile devices in your network and share data or an Internet connection, but it can also allow outsiders to gain access to your network if your security is not sufficient. Wireless connections are also slower than wired connections and prone to interference from radio signals or other electronic devices. Weak Wi-Fi signals lead to slow data transfer or dropped connections.Know More
Wi-Fi networks are also more complicated to set up than wired connections. In addition to basic networking configuration, administrators also have to consider what type of Wi-Fi signal each device uses. Older devices may be limited to slower 802.11b and 802.11g standards, while new hardware can use multiband technology such as 802.11ac for faster speeds. In many cases, wireless routers communicate with multiple Wi-Fi standards, but older hardware on the wireless network can cause a bottleneck for all data connections.
An unsecured wireless network is also a beacon to hackers. The original wireless security protocol, WEP, can be broken in minutes, and even modern WPA2 security protocols are vulnerable to certain types of attacks. Any wireless network requires careful monitoring to ensure no unauthorized users make it past security and gain access.Learn more in Internet & Networking
A Wi-Fi connection is a wireless connection that connects a device to a network using a wireless router. Wi-Fi connections allow electronic devices to exchange data or connect to the Internet. Devices that use Wi-Fi connections include personal computers, smartphones, video game consoles and tablets.Full Answer >
Most routers provide Wi-Fi coverage for about 100 feet in all directions, according to How Stuff Works. Range extenders or repeaters can be used to expand this distance.Full Answer >
The main ways to extend Wi-Fi coverage include upgrading the router and network adapters, installing a high-gain antenna and putting in additional access points. These can be traditional access points or wireless versions. Wireless repeaters also extend Wi-Fi coverage areas.Full Answer >
Wireless local area network (or WLAN) is a network of computers or devices that uses high frequency radio signals to communicate data, while Wi-Fi, short for wireless fidelity, is the trademark name used to identify WLAN-compatible devices.Full Answer >
