I have an Airport Express 802.11n, a time capsule (802.11n) and also an Airport Express 802.11g. I am trying to setup a network. I connected the AE802.11n to my cable modem. Everything worked fine. I then set this up to run as a WDS. Then I reset/powered up my AE802.11g and tried to set this up as part of the existing network. However, my AE802.11n then went into yellow-blink mode before I could do anything in Airport Utilities. Im using up-to-date firmware. the only way I can get my main AE802.11n to repond is unplugging the AE802.11g !!! Any ideas what I am doing wrong? Is the AE802.11g compatible with the AE802.11n? Should I be using WDS or wireless extender mode? Thanks M.
