AP Express kopplad till Ethernetskrivare? Ja eller nej?

Kan man ha en AE vid sitt adsl-modem på husets plan 1, och en till AE på ovanvåningen som kopplas till ett nätverk (icke trådlöst) som redan är draget där? Eller är det det som inte går i och med att den endast har en WANport i st f en LANport?

På ovanvåningen vill jag ha AE's ethernetport kopplad till en router som står i en garderob och är i sin tur kopplad till RJ-45-jack i 3 olika rum däruppe.

Denna info har jag hittat hos Apple. Men jag fattar inte riktigt allt ändå. Någon av er klokhuvuden som kan fortsätta hjälpa? Tack!

Question: Can AirPort Express act as a bridge?
Answer: AirPort Express can act as a bridge in three different ways:

If you have an existing wired network, it can bridge this network to wireless clients.
If it is set up as a WDS remote or relay station, it can bridge the wireless network to wired clients.
If it is set up as a WDS remote or relay station, it can bridge the wireless network to wireless clients (or "wirelessly extend" the range of the network).

Question: Can AirPort Express be used for a Wireless Distribution System (WDS)?
Answer: Yes. AirPort Express can be a WDS main, remote, or relay station. It can function as a WDS main whether or not you are using it as a router to share your Internet connection (NAT).

Question: Since AirPort Express only has one Ethernet port, does it act as a LAN port, WAN port, or both?
Answer: Depending on how you have it set up, the Ethernet port can function as a LAN port (defined as either simple bridging or distributing NAT-based "private" IP addresses) or a WAN port (connecting to your broadband Internet service provider or upstream router). However, it never acts as both simultaneously in the way that the original AirPort Base Station (Graphite) can. When the AirPort Express is functioning as the router responsible for sharing your Internet connection (NAT), the Ethernet port acts as a WAN port. When it is set up as a WDS remote station, it can act as a LAN port. Assuming that your Internet service provider only gives you one IP address (the most common scenario for homes), this means that AirPort Express can only accommodate wired clients when acting as a WDS remote base station or bridge. Therefore, if you need to support wired clients and only want to get one base station, you should get the AirPort Extreme Base Station instead.
