Hi, I know next to nothing about older Apple networking or OSX. We have an iMacG4 (aka the lamp iMac) with OSX and a functioning Airport card. It can detect another Apple network at a neighbor's house down the street, but cannot detect my trusty old WRT54G that all my PCs are networked to. Am hoping there is a simple fix? Would my Wireless encryption settings make any difference? I haven't changed them in years, so I have no idea what I have anything set to. I do have the network password protected. Would really like to get this computer on the network. Have a very specific use in mind. If I need to buy additional hardware, I will. Hard line connection is not an option. Thanks.
