Extending AirPort's range with multiple base stations Network
I used a second AirPort base station (version 1, grey) to extend the range of my first base station (or any other access point) for sharing my internet connection. With that, I'm able to access the internet with a remote computer that has no direct access to the first AirPort base station. Please don't tear me appart for the use of the word "repeater / bridge". I know, it's technically not correct, but I think it describes somehow what I was doing here. Here is how I set it up:

Base station 1 -> Computer 1 + Base station 2 -> Computer 2

The computer 1 is in range of base station 1. I connected base station 2 (ethernet port) with a crossed-ethernet cable to computer 1's ethernet port. The following settings were necessary:

Configuration of Base station 1:
Standard settings, using DHCP.
Shared IP range that I used: 192.168.1.x
with Basestation 1 being the router @

Configuration of Basestation 2:
Internet tab
Connect using: Ethernet
Configure: Using DHCP
IP address: leave empty
Subnet mask: leave empty
Router address: leave empty
DNS servers: leave empty
Domain name: leave empty
DHCP client ID: leave empty

Network tab
Distribute IP address: CHECKED
Share a single IP address (using DHCP and NAT): CHECKED
DHCP lease: 60 min (default)
Enable AirPort to Ethernet bridging: CHECKED
all others: leave empty / unchecked

At the beginning, it should show; at the end, it should show, but not editable. I don't know exactly why that range was shown, maybe because I used it some time before?

System Preferences - Network:
Airport - TCP/IP Tab
Configure: Using DHCP
all others: leave empty
IP address, subnet mask and router should be filled in automatically from base station 1 with DHCP active. If you used the IP range 192.168.1.x, IP address should be, subnet mask and router

Built-in Ethernet - TCP/IP Tab:
Configure: Using DHCP
all others: leave empty
No other information is automatically entered, so don't worry...

System Preferences - Sharing - Internet Tab:
Click "Start" for sharing your Airport connection. You should see in small letters: "You are connected to the Internet over AirPort. This connection will be shared with computers connected to Built-In Ethernet." That's it.

If you go back in the base station admin utility, checking on base station 2, you should find under the Internet tab that IP address, subnet mask, router and DNS servers have been entered. Now try to connect any computer out of distance of Base station1 to Base station 2. It should be able to connect to the Internet through the Base station 2 and Computer 1.

[Editor's note: I have but one base station, so this one's untested...]

roaming doesn't require e computer in-the-middle. you can setup roaming with just the 2 base stations. Check Apple's "Designing Airport networks" document.

Yes and no.

What you mean is using airport basestations in a setup called "roaming" (-> Apple Tech Docs).
But that requires, that all basestations are connected via ethernet to the LAN.

I haven't found any solution yet, where I can set up a basestation (without being connected to a computer) that picks up a network "wirelessly" and re-transmits it.

I don't know at all if a basestation can in fact "join" a wireless network in a way an airport /WLAN enabled computer / laptop does...

Anyone ?

Only the first base station has to be connected to the LAN via ehternet. All of the others don't. As long as they are in wireless range of each other all they need is power via a wall outlet. Base station 1 which is connected via ethernet passes info to base station 2 wirelessly which then passes info to base station 3 wirelessly, and so on, and so on. All of the other base stations pick up info from one another.

Only Airport Extreme supports wireless bridging (or wireless distribution as Apple calls it):

Not with Version 1 Basstation (grey)
Authored by: reinmund on Feb 14, '03 05:04:59PM

I don't think that works, neither with Version 1 Basestation (grey) nor Version 2 (white).

If you indeed have a solution, please post how you set it up.
Or give links to Apple Tech Docs.

The Lynchpin is the Computer in the Middle
Authored by: madmizzen on Feb 14, '03 10:21:30PM

From everything I have read the ability to bridge wireless networks, or repeat them is a function that is dependent on the new Airport Extreme base-station (and some other wireless products notably the Linksys WAP11). What the hint poster is doing is to use a computer in the middle to make all this magic work.

DSL (or some such) <ETH>BASE 1<802.11>COMP 1<ETH>BASE 2<802.11>COMP 2

In the case above he is taking advantage of the internet sharing inherent in OSX, but you could just as easily use a linux box or router in the space of COMP 1.

I know this is redundant information for some of you, but I have been confused by this stuff before (a week trying to get afore mentioned Linksys WAP11 to work) so i thought I would throw my two cents in

The reports I have are the Linksys WAP-11 only works in "bridge" mode with another WAP-11 (or maybe another Linksys router).

Also, it can either act as a wireless access point or a wireless bridge, but not both at the same time.

It cannot act as a wireless to wireless bridge. In "bridge mode" all it can do is act as a "client" of another WAP-11 which then gives you an ethernet connection for a computer, network printer, etc.

Extending AirPort's range with multiple base stations
Authored by: Winston on Jul 09, '03 12:37:37PM

This is a really neat use of an extra ABS and an AirPort equipped computer. A couple of thoughts:

- AirPort Extreme Base stations can do wireless to wireless bridging from one central AEBS to up to four other AEBSs in a "star" pattern. You can only get one "hop" - i.e. the main AEBS signal can be forwarded one time by a second AEBS, but the signal from the second cannot be forwarded again by a third (although it could with the trick in this post).

My guess is that like the D-Link mentioned below, the wireless signal loses half its speed when repeated by a second AEBS.

- The D-Link DWL-900AP+ Access Point works as as stand alone repeater:
the signal loses half its speed on each repeat or hop.

- the graphite ABS can only use the IP address range to for DHCP. This is the default Apple set up, and is part of one of three ranges allowed for "private" (behind a firewall on a LAN) IP addresses. The graphite ABS can, however, recognise to The upper range is good for something like a network printer. "Snow" or "white" ABSs use to for DHCP and to for "also recognised".
