Activate Wifi on the PS3 under Linux
The Wifi on the PS3 in Linux takes a little bit of work to activate wireless networking to use eth0 (Linux ID for the networking device). This unforently only allows for either a wired OR wireless connection NOT both. This is due to limitations of the Hypervisor that all otherOS (in this case Yellow Dog Linux) have to go through to get to the hardware.
