Q: Can I use Apple’s Backup in conjunction with a USB drive attached to a new AirPort Extreme Base Station? ~ Calvin Johnson A: You can. And there’s a good reason to do so if you have a bunch of Macs: Using this scheme, you can back them all up to a single drive, because it [...]

Faster Wireless Network Speeds via Base Station Modes

17. November 2007

0 Comments

Apple’s Airport Extreme Base Station supports multiple WiFi standards, but allowing computers that use different wireless modes (802.11b, g, and n) to use the same base station slows everyone down. To allow each computer to communicate at the fastest possible speed, try using several base stations and limiting each one to a single WiFi standard. To [...]
