Perhaps the greatest technological advancement in networking the past decade was not the progression to the 10 Gigabit/sec standard, but the capability to connect to home and business networks wirelessly. For the residential user this permitted the capability of connecting several computers in various locations throughout the house.
For the business end, this technology permitted businesses to bridge close geographic locations without running leased lines and permitted vendors to have remote access without technical staff onsite or unwieldy cabling.
The evolution of Wifi is growing by leaps and bounds from year to year. From the original 2Mb/s connection of the original wireless protocols from the military to the current wire speed equivalents using pre-N and spectrum bonding, Wifi has come a long way, proving the naysayers wrong at every turn.
What is evident now is that WiFi is here to stay! Take advantage of the advances in security, speed, and capability that an access point offers. Double traffic to your coffee house with free wireless. Connect that spare PC in the basement to the internet. Pin your children head to head in their own rooms on the latest MMOG. The possbilities are endless!

The greatest deterrent to incorporating wireless access by both residential and business consumers is the often misguided fear of intercepted credit card numbers and personal information freely trnasmitted through the air. Although initial implementations of WEP (Wired Equivalent Protection) had some loopholes, the evolution from WEP2 to the current WPA (Wireless Protected Access) virtually eliminates any opportunity hackers have at getting to your data.
In many cases, compromised data is often a side-effect of using default settings from a wireless access point or lack of security encryption options and misconfiguration. Even older equipment can be reprovisioned with an IOS or firmware upgrade with the latest security standards. Don't throw away that 3 year old access point, with the proper firmware, it may be compliant with today's stricter security standards.
Oftentimes many customers will return hardware because of the dizzying array of options that today's networking devices offer. Due to the various options now available, it can be very intimidating to create a network mingling wired and wireless while keeping security at a premium.
