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.Continue Reading
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 about Internet & Networking

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 >
A digital subscriber line, or DSL, Internet connection is no more secure than a Wi-Fi connection when appropriate security measures are not taken before use. DSL connections are always on, and without the protections provided by a software or hardware firewall, they are open to nefarious intrusion.Full Answer >
