Apple has informed its official retail stores, AppleCare employees, and authorized resellers that a small number of third-generation Apple TV units have WiFi issues. These issues surround not being able to locate a WiFi network, unable to join a network, and dropped or intermittent connections.
Apple has determined that a very small number of Apple TV (3rd generation) products might experience one of these Wi-Fi related connectivity issues: Cannot locate network, Unable to join network, Dropped or intermittent connection.
If an Apple technician determines that an applicable Apple TV has these issues, the unit can be replaced as part of a replacement program that Apple has begun because of these WiFi issues. Apple says that replacements can be offered free of charge up to two years after the device’s purchase date.
Here are the serial number pairs that are eligible:
Apple is preparing to soon release new Mac computers that support super-fast 802.11ac Gigabit wireless, according to code-findings inside of Apple’s latest OS X Mountain Lion 10.8.4 beta seed to developers. The code was located by a tipster inside of the operating system’s WiFi-frameworks folder. As you can see in the image directly below, the 802.11ac code is not found in OS X 10.8.3, which is the latest public release of Apple’s Mac operating system.
Previous reports have claimed that Apple is working with wireless chipmaker Broadcom to produce 802.11ac chips for future Macs. Now, it appears, Apple’s software is ready to support the new wireless technology as well. More details below…
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.
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…
