If the wireless ethernet adapter is PCMCIA, which is a standard type of slot that has been found in notebook PCs for the last eight or en years (It would have its own antenna), you need to pull the blank PCMCIA slot filler (a piece of plastic that keeps dirt out of the slot) out of the slot, and plug the adapter in. The 1150 has an optional built in wireless card. If this is what you have, you need to open the machine with a small screwdriver that will fit the screws holding the back of the laptop on the machine. If you need to do some disassembly, whatever you do, do not turn the laptop so the keyboard is facing up until the back is securely in place again.
You may wonder why you need to leave the machine face down. If you don't, everything will fall out, and the keyboard keys will go all over the place. Configuration of the wireless adapter is specific to the chip manufacturer and model number. There is a single chip that does the work of the adapter, or perhaps on a wireless card two chips. Linksys has been known to use Realtek chipsets in some of their wireless laptop cards. They have also been known to use chips that are compatible with the Prism 54 driver that is part of the Linux kernel as of 2.6.22, or so.
Fedora is known to compile all ethernet devices into modules, and load the ones that are needed. If your issue is with configuration, Fedora 7 should do this also. I don't know how long you've been using Linux, so it is hard for me to give much detailed info, especially not knowing any details about the problem. I hope some of this has helped you. I'll try to watch this thread.
