Archived - Using wireless routers with WEP and Remote Install Mac OS X
You may notice you cannot use the "Remote Install Mac OS X" feature to install Mac OS X across wireless routers that use the WEP (Wired Equivalent Privacy) security algorithm.
When holding down the Option key on startup, no WEP-enabled wireless networks appear, or can be selected.
Remote Install Mac OS X is not compatible with WEP-enabled wireless routers. The WEP algorithm does not provide optimal security for wireless networks and is not recommended.
Changing your wireless router from WEP encryption to a more secure standard (such as WPA or WPA2 Personal) enables remote installations of Mac OS X and enhances the overall security of your wireless network.
