Problems with Airport Extreme Basestation

I recently purchased a new 27" iMac to replace a Early 2004 iMac. I have a Airport Extreme Basestation connected via CAD 5 cable to the iMac. When the iMac boots many times the Airport Extreme does not propperly connect. When I open the Airport Utility I have Internet but the harddrives don't mount and if I click on the Airport Icon in the utility it asks for my password. I enter my password and it does nothing. I have to unplug the Airport Extreme then replug for a proper connection. It is either Mavericks since I had Mountain Lion on the older iMac and the day I received the new 27" iMac Mavericks was released. Anyone have any ideas on how to fix this?
