      Antenna Types

      In antenna engineering, a dipole is the most basic type of antenna and serves as basic framework for all other antennas. Dipoles consist of a metal rod that acts as a conductor with a radio feed line at its core. The conductor splits the signal and creates a positive electrical charge on one end of

      802.11g

      802.11g is one of the standards used for high speed wireless networks, commonly known as Wifi. This standard was created by the IEEE (Institute of Electrical and Electronics Engineers) in June of 2003 and uses a 2.4 to 2.5 gigahertz radio frequency to send and receive data from one device to another. There are several

      Wireless Networks

      Wireless networks are those computer networks that use electromagnetic waves instead of wires in order to carry signals over the various parts of the network. Wireless networks which run over other wireless networks often utilize the lower layer networks to provide security and encryption. Stand-alone wireless networks either provide their own security and encryption features

      Netopia Default Password

      Netopia is a popular broadband product company that produces Internet routers and other WiFi devices. Motorola acquired the company in 2007 and made partnerships with wireless providers around the world. Such providers include AT&T, Swisscom, and NextGen Tel in Norway. Unlike other router brands, Netopia’s default password is the 6 digit serial number located on

      How to Reset a Netgear Router

      Netgear routers are some of the most popular routers in the world, providing both residential and commercial users with wireless networks that are accessible from a wide variety of mobile devices such as laptops, tablets, smartphones, and even desktop computers that are outfitted with a wireless adapter (which Netgear also sells). Netgear routers are available

    • RSN (Robust Secure Network)

      RSN (Robust Secure Network)

      RSN (Robust Secure Network) is a protocol for establishing secure communications over an 802.11 wireless network. RSN (Robust Secure Network) is part of the 802.11i standard. The RSN Protocol Process The RSN protocol functions as follows: The wireless NIC sends a Probe Request. The wireless access point sends a Probe Response with an RSN Information

    • WEP (Wired Equivalent Privacy)

      WEP (Wired Equivalent Privacy)

      Wired Equivalent Privacy (WEP) is the encryption algorithm built into the 802.11 (Wi-Fi) standard. WEP encryption uses the RC4 stream cipher with 40 or 104 bit keys and a 24 bit initialization vector. WEP Key Generation Most 802.11 devices allow WEP keys to be entered using an ASCII passphrase or in hexidecimal format. The conversion

    • MAC Address Filtering

      MAC Address Filtering

      MAC Address filtering is a technique that is implemented on many wireless networks to filter which devices are able to connect to the wireless network. MAC Address filtering allows an administrator to allow specific devices to connect to the network while blocking all other devices. MAC Address filtering is a free service provided by most

      How to Change WEP to WPA

      Changing WEP to WPA is a great way to increase a wireless network’s security. These are the two main types of protection available through modern wireless routers: WEP or Wired Equivalent Privacy is a security algorithm that wireless networks use. Hackers can break into wireless networks using WEP very easily with simple software that is
