I have a PC that would need to be "wirefull" (lol), and then my macbook which is wireless of course, and my father would be running a laptop as well, which is also wireless. So I guess the airport express would be perfect, right? Since I only need my desktop PC plugged into it?
I am interested to know what the difference between this and the Apple Base station is then... Range? Speed?
Erm... no, not exactly... there's no simple or elegant way you can do this with just the Airport Express. It only has *one* ethernet port TOTAL, including the one that you're using to connect it to the internet.
You could...
(1) Connect the modem directly to the PC, and then share through the PC's ethernet card (but basically only if either you can connect the modem to the computer by USB or the PC has two ethernet ports). The PC would have to be on all the time to be able to do this... I really wouldn't recommend using a several $100s PC to replace a $20 router.
(2) You can use a wired router in conjunction with the airport express...including the one you've got. You plug the wired router into the modem and then you plug the airport express into one of the wired router's LAN ports
(3) You can use another router that has LAN ports (Airport Extreme Basestation, Linksys, Netgear, etc).
In terms of differences between the AEBS and the Express, assuming you're talking about the new AEBS (802.11n):
- AEBS is faster (even with 802.11g clients, because of MIMO) and longer range (802.11n clients only)
- AEBS can support both hard drives and printers on the USB port; only one printer on the Express.
- Express can stream music but not video; AEBS cannot stream anything.
- AEBS has three lan ports; the Express has none.
Compared to the old AEBS (the one that looks like a mushroom top or a UFO), the old AEBS can handle more clients, has one LAN port, and cannot stream anything.
What Linksys do you have? Is it a WRT54G, or is it a wired one? What's wrong with it? Their routers are generally excellent.
