The only updates that appear in the Software Update window are those that are required by your machine. The version for the Intel mac did NOT get downloaded to your machine and likewise, the version for the G4 did not get downloaded to any Intel Mac.
So, unless there has been a minor catastrophe, the update you got is the one that is for your machine.
Where did you learn that it was not for your build version?
You might want to take a look at your airport settings to see if anything got reverted to a default position and that you still have access to the hotel network. if you cannot find the problem, I'm not sure there is a way to remove the security update. This was not a software update as such.
Try using an ethernet cable into the router in your room and see if it works that way

Help please! I have recently downloaded AirPort security update 2006-001 for Mac OSX. I have a powerbook G4, not an intel mac. Although apple's update said it was for all macs, I have since learned that it is not for the build version of my computer. I am using my computer on a hotel wireless network. Since installing the update I cannot get anything from the web even though the computer says I am connected to their network and shows a full strength signal. Being relatively new to mac, can i remove the update and if so how do I do it? Any help would be greatly appreciated.
