Bandwidth may be getting cheaper and more available all the time, but you wouldn’t guess it from AT&T’s latest announcement. The company says that, starting 1 October 2011, it will limit throughput rates for the top 5 percent of data users with unlimited plans — whose use is what AT&T calls an “extraordinary” amount of data. AT&T takes pains to point out that this will not apply to the 15 million smartphone customers with tiered data plans or 95 percent of those with unlimited data plans. follow link
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
