The answer is "yes, but." Yes, your PowerBook can plug into the network, but it has to have an Ethernet adapter (PC card), and you might have to buy an extra IP address. Whether this is the case or not depends on your Router and your ISP. If you just have one IP address allocated to you by your ISP, your router will probably have to have some way of sharing it with those other machines. Your SpeedStream router probably do this with NAT (Network Address Translation http://webopedia.internet.com/TERM/N/NAT.html) -- to ensure it's turned on and properly configured you'll have to consult your documentation and/or contact Efficient for help. I've heard tell that Windows 98 has built-in Internet sharing features, so if you have a machine running Win98, you might be able to accomplish what you want using that, even if you don't have a router with NAT. If you don't have a way for multiple machines to share one IP address, and you don't have multiple IP addresses allocated to you, you'll have to get appropriate hardware/software or talk to your ISP about getting another address. Like I said before, the quickest way to figure it out is to plug it in and try it. Just set your TCP settings to try and pick up an IP address over DHCP, plug in the Mac, and try to connect to the Web. This is all fairly new to me, too, so I might have gotten something wrong here. Talk to your ISP and consult the SpeedStream documentation. zm At approximately 8/16/00 3:11 PM, the esteemed kevin raleigh (krr at ix.netcom.com) typed the following: > I was wondering if I could plug the powerbook into a exisisting network that > uses ADSL without the notebook having to install special software??
