<div class="im">Hi Paul,<br> I'm a little confused by this statement:</div><div><br><div class="im">"I got for a few days now a "Self-assigned IP address" message when I
select the Airport Extreme in our iMac to use it to connect the iPad 3G."<br><br></div></div><div class="im">My ipad connects directly to the airport extreme, without interaction with my iMac. Can you perhaps rephrase your statement?<br>
<br>Are
you setting the LAN address of the airport to 192.168.0.1, or the WAN
address? You probably need to leave the WAN address alone, that address
should come from your internet provider.<br>
<br>I don't have my setup in front of me, but, in a nutshell, My
internet service provider (ISP) uses DHCP to provide a WAN address to my
airport extreme. My airport extreme in turn uses DHCP to provide LAN
addresses to the devices inside my network. Each device is set to use
DHCP to get an ip address.<br>
<br>So, try to answer these questions:<br>1) Where does your airport get it's WAN (outside address)?<br>2) What is your airport's LAN (inside) address?<br>3) Is your airport extreme set to provide DHCP addresses to the devices inside your network?<br>
3) Are your inside devices set to use DHCP to get addresses?<br></div><div class="im"><br>Clue: LAN addresses usually start with 192.168. or 10.0.<br>Clue2:
The airport extreme has a WAN address and a LAN address. It's LAN
address is usually 192.168.0.1 or 10.0.0.1. The WAN address is assigned
by your ISP.<br>
Clue3: Two devices on the same network cannot have the same address.
For example, if your Airport Extreme's LAN address is 192.168.0.1, your
ipad and imac should use 192.168.0.2 and 192.168.0.3 (or some other
address on the same 192.168.0. subnet).<br>
<br>Clear as mud I'm sure......<br><br>Good Luck,<br> Drew</div><br clear="all"><br>-- <br>--<br>Andrew T. Lynch<br>
