Thanks for the pointer, I'll try it in the morning. I do have a router. The the problem is that i have never been able to consistently get the laptop to work with any network other than the one at school or wireless networks.

This is odd. First of all, my Windblows laptop is alleged to have built-in WiFi. However, I have never been able to find any wireless networks with it. So, I bought a LinkSys WiFi A card for it a few weeks ago. (It was only $5.00. So I figured what the heck.) With this I had no trouble getting on the wireless network I set up for my parents. ($10 LinkSys wireless A router.) I was also able to use it to get onto the wireless networks at both of the hotels at which I stayed on the drive back here to Texas.

Now I am still having trouble with getting it connected to a wireless network with my G5. I have turned on sharing my internet "from Built-in Ethernet To computerusing: Airport" in the Internet tab of the Sharing preferences pane. I have also turned on Personal fire sharing in the Services tab of that same pane. Now my laptop (using the LinkSys card rather than the alleged built-in WiFi) can see and connect to the network, but neither of the computers seems to be able to see the other to share files. So anybody got any ideas as to where I should go from here?

(I was about to write that my laptop also could not get to the Internet via the network because my first attempts to access it via web browsers failed. Then while I was writing this post the one of the other internet based applications started to beep at me indicating that it had receive some data. I went back and found the internet connection working at least.)

Also, I am picking up some other wireless networks in the area. So, I would also like to know how to secure my network to keep others from piggy-backing on my signal when it is on. I thought I had it figured out, but I can't seem to get the laptop to connect to my wireless network if I have it secured. In the Airport options sections of the Internet tab of the Sharing pane, I set a password and verify it. Then when I try to use that same password on the laptop to connect to the network it does not work. So, any help on these two problems would be appreciated. Thanks.

It sounds like that Linksys card is 802.11a, which is completely incompatible with 802.11b and 802.11g. I'm surprised you're able to connect to the Powermac at all if it is. As for the other wireless stations, I'm surprised there are so many 802.11a stations out there, as I thought it was a dead standard.

My bad. I knew it was the first widely available version of the technology and the one that Apple used for its Airport hardware. So, I assumed that it was the "a" protocol. A quick look at the box would have revealed to me that it is in fact the "b" protocol. Sorry for the miss understanding.
