MacWireless today announced its 3-port Powerline Network Adapter. Powerline networking allows you to route your network through the already installed home/office power lines with speeds of up to 14Mbps. MacWireless says that Powerline devices can work over up to 600 feet of electrical wiring--enough range to cover most homes in the US. The 3-Port Powerline Network Adapter ($80) works in exactly the same way as MacWireless.com's single port adapter, but with the added flexibility of a built-in 3-port 10/100 ethernet switch; it also includes built-in surge protection up to 475VAC. The company also lowered the price on its single-port adapter to $50 ($10 reduction) as well as on its WiFinder Keychain hotspot finder to $20 ($5 reduction).
