I am trying to configure a roaming network inside an office building with 2 airport extreme base-stations. In the past, we have used 1 basestation with great success. But we have a cinderblock wall that we are contending with now and the signal degrades too much on the other side. So, I bought an additional Airport Extreme and first tried to set up an extended network. That didn't work because the two could not see each other. So, I decided to run a cable and go with the roaming network.
I have now run a cable from the primary base-station to the slave and plugged that into the WAN port of the slave. I have pretty much followed the instructions on apple's site (although they refer to the older version of the airport admin software) and after two times, got it to work. However, the problem I am having is the network is not properly distributing DHCP addresses, and am getting several of these 169.254.xx.xx numbers that do not work. However, if I manually define a static IP for the device on the wifi, it works. So, the problem MUST lie in the DHCP situation.
Here is how my network is somewhat different:
1 - We have multiple DHCP servers on our network. The main intenet router (192.168.1.1) is serving a small block (192.168.1.225-240) for DHCP for any guests NOT using wireless. The main airport (static, 192.168.1.111) is ALSO serving DCHP (192.168.1.160-190) for wireless clients.
2 - I want to connect the 2nd base station and give it a static IP (do I really need to do this? When I tried in the beginning, the 2nd base did NOT get an IP assisgned from the first airport, maybe because it is wired?). The airport software keeps wanting to change it to DHCP instead for some reason. It appears to have kept the static config (192.168.1.114) even though it now says DHCP. Strange.
I am simply trying to get this roaming network to work properly. If I disconnect the slave station, everything works fine.
Thanks so much for your help!
