What Is Wireless N?
Wireless N is a common name for computer hardware that supports 802.11n Wi-Fi wireless networking. Standard types of Wireless N hardware include network routers and adapters.

802.11a vs. 802.11b/g/n vs. 802.11ac Wi-Fi Standards
This article examines the pros and cons of 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac and Bluetooth for WLANs.

What is Dual Band Wireless Networking?
In Wi-Fi wireless networking, dual band is the capability to transmit on the 5 GHz band of 802.11a and also the 2.4 GHz band used by 802.11b/g/n. Dual-band Wi-Fi is a feature of some wireless routers and network adapters. Some cellular phones also utilize a kind of dual band communications, separate from Wi-Fi.

These ten wireless devices or services all have one things in common - the use of either "Wi" or "Fi" in their names.

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?

802.11ac is the version of Wi-Fi designed to replace 802.11n. 802.11ac was officially ratified in January, 2014 but Wi-Fi products based on this standard have been available for some time longer.

802.11n is a standard for high-speed Wi-Fi networking, operating at greater than 100 Mbps. 802.11n is designed to replace all of the earlier 802.11a, 802.11b and 802.11g Wi-Fi standards.

Do You Need to Upgrade to 802.11n Wireless-N?
802.11n provides higher network bandwidth compared to other forms of wireless networking. And compared to older Wi-Fi technology, 802.11n also offers better signal range at least in some situations. Do you feel compelled to upgrade your router or other wireless equipment to Wireless-N?

802.11b is an industry-standard technology for wireless communication via Ethernet. Because of its low cost and established history, 802.11b is commonly found in home networks.

802.11a is an established IEEE standard for wireless networking that improves on the performance limitations of 802.11b. 802.11a is a relatively high cost solution found in some business networks.

802.11 - 802.11 IEEE Networking Standards
802.11 is a family of standards for wireless local area network (WLAN) networking. This page describes each of the "802.11X" standards including 802.11a, 802.11b and 802.11g.

Choosing The Best Wi-Fi Wireless Channels for Your Network
You can leave your Wi-Fi router and network configured to use default wireless channel numbers in many cases. However, choosing a channel wisely can also help work around certain kinds of network issues.
