I own an Apple iMac G5, this has not such a strong Wi-Fi reception, but sometimes it can access the Internet. That's why I bought the product offered up to reflect on the power grid Internet. It works just fine! While it noted that the speed is a little lower than if you were to connect the computer directly to a LAN cable, but at least it works consistently. In Windows you can simply in the network connection list select the appropriate compound that is produced by the Allnet Powerline device. In Macintosh, however, it should be noted that firstly the Ethernet connection configured in the system settings under network that the IP of your computer is automatically determined via DHCP and is not set manually (ie tab "TCP / IP" - then in "IPv4 Configure Setting "" DHCP ").
