i recently purchased a couple of goodies... 2 airport express and one extreme... i have the extreme connected to my modem.. one express connected in back of my stereo, connecting to my network and expanding my network, using the simple set up.. not manual and my last express in another part of the house, doing the same. my problem is that once in a while i don't see my airport expresses on the utility... and i hate to restart them.. everytime.. they should work no matter howlong they have been plugged in i think.. not just plug in when i need to use them.. specially when i am using them to expand my network. is there a reason why i can't read them all at once sometimes? at least not until i restart them...? anyone has problems with them?
