what i'm gonna do.
I plan to do the same sort of thing, but I don't really see much of the advantage of making desktops wireles.., i mean, how much do you move them around? I have to ask myself, am I really that Lazy to not run a little cable? Plus pay 50-100 bucks for each desktop's wireless card.
What I am going to do is just get a Linksys BEFSR41 4 port Router with built in switch and connect my Rev A iMac and my PC to it with ethernet.. THen when I buymy Ti2 laptop, I am going to get it with an airport card and then buy a wireless card for my PC and make it a base station..
You say it is slower, but think about it.. if you do all the desktops on wireless, you are really kicking yourself! You will go from 100Mbps to 11Mbps. All to save a bit of time wiring? NOt for me. WHen I use the PC as a accesspoint, I am pretty sure it would be able to handle the 11Mbps, it's slow anyway compared to the 100Mbps I will get if I am close to the Router with My laptop and can just plug in.. I'll have the option, but if I want any file sharing to the other computers, I'll want the speed of the 100Mbps, granted I won't need more than about 8Mpbs for my Cable modem.. I get up to about 8Mpbs, anything else is wasted.
DBU, the school I go to just installed the CISCO Aironet 350 system on campus and from what I have read on Cisco's site, it is compatible with the Airport. (Wi-Fi), but the tech guys say otherwise.. We'll see..
