I installed the latest copy of YDL on the PS3 fine, but when I follow the guide to setup wireless, in the step which says select the PS3's wireless device, I can't, as it isn't there.
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.
Log into YDL as a user
Unplug the wired network cable
Open the Network configuration menu by clicking on the Yellow Dog logo (Menu Button) from the main shelf, then follow the menus Applications > Applications > System Tools > System Config > Network.
Enter the root password when asked (for security purposes)
Click on the Hardware tab
Select the Sony PS3 Ethernet Dev
Confirm deletion by clicking Yes
Confirm again by clicking Yes
Set up the Wireless connection
Click on the Devices tab
Click on "Deactivate"
Select Wireless Connection
Select the Sony PS3 Ethernet Device (eth0)
Set the mode to Auto
Select Specified: forNetwork name: (SSID)
In the box provided enter the SSID of your access point (this can be found in the management settings for your access point
Select the Channel that your access point is using (this can be found in the management settings for your access point) (NOTE: only channels 1-11 are legal for use in the USA, please check local laws for other restrictions)
Set the Transmit Rate to Auto
If your access point does not use encryption make sure the box labeled Key empty, if it does please complete the Encryption selection below now
If your Network is using DHCP to hand out IP address or if you are unsure select Automatically obtain IP address settings with DHCP
Test your connection, it should be active
