It takes ages for my iMac and ibook to detect my airport express after I put the computer to sleep. Even if I shut off the imac and turn it back on, it doesn't detect the express right away. I have to shut everything off - the router, the express, and the imac, and only then will the express be instantly detected again. Here's the current configuration: The express is connected to my existing wireless network powered by a DI-524 DLink router. I am only using it for AirTunes and as a print server. I have tried having the router assign a static ip address to the express rather than a dynamic one, but this doesn't seem to make a difference. I have also configured the ip address manually on the express to reflect the static ip I set for it on the DLink router. Still no difference. I have hard re-setted the express several times and reconfigured it to no avail. I can turn everything off and back on again, and then iTunes and printing apps detect it, but if I put the computer to sleep and wake it again, it either takes the imac ages to detect the express again or I have to repeatedly scan for the express using the Airport Admin Utility. I can't seem to find a solution.
