XFI Pods

What is the deal with the XFi pods contantly going down during the day?  I don't have a large house and have three of them set up throughout because the main base station signal does not travel far enough.  But these pods multiple times per day are blinking and trying to reconnect.  My computers have wired connections and as long as the service iteself is active thye work fine. (All be it nowhere near gigabit speeds that I pay for).  But the pods continuously fail.
