Use Mountain Lion’s new Wi-Fi Scan utility to optimize your home wireless network

A new Wi-Fi scanner tool is in Mountain Lion’s refreshed Wi-Fi Diagnostics Utility, allowing users to easily discover Wi-Fi networks within range and view related data not available from Apple’s Wi-Fi menu bar item. Comparable to third-party Wi-Fi stumbler tool iStumbler, the scan tool provides data for BSSID, band, protocol, channel, signal strength, security, and more. It also has Active and Passive scan modes.

From the window, you can see what networks are in your area and their strength. Some maneuvering of base stations can increase coverage to the outermost areas of your house, and it is much, much easier to see slight differences in numerical signal vs. noise strength over those four waves Apple uses in its Wi-Fi menu.

Additionally, by looking at what Channel (1-13) your base station is on, compared to your neighbors (or other base stations in your house), you can often find the least used channel in your area to improve reception.

If you are interested in using the new Wi-Fi scanner tool, OSX Daily provided the necessary steps for quick access:

Broadcom launches next-gen 5G Wi-Fi chips with gigabit ethernet speed and increased range

Broadcom Corporation is a global innovator for wired and wireless communications, and today the company announced its first family of 802.11ac chips designed for a broad range of product segments.

The chips, also called “5G Wi-Fi” by Broadcom, do not correlate with 3G and 4G cellphone networks. The BCM4360, BCM4352, BCM43526 and BCM43516 chips improve Wi-Fi’s range and are significantly more efficient. Perhaps, the most tantalizing aspect is that the 5GHz-based technology has speeds beyond 1Gbps and is currently in the high-end range of consumer Ethernet.

Apple currently uses Broadcom Wi-Fi Chips in its Mac line and in its iOS devices, including iPad and iPods.  The latest MacBook Airs have the Broadcom BCM4322 Intensi-fi® Single-Chip 802.11n Wi-Fi Transceiver.  Maybe we will see something a little faster later this year…
