That's perfectly acceptable- I bought an R7690P back in december which apparently has a flaw in it that when you power cycle the device, it reverts to factory defaults. Netgear's response is "take it back to the purchase place for an exchange, or pay for a support call to swap it, even if it's under warranty."
I replaced it with a TP-link something or other and DD-Wrt'd it- even though that firmware is still beta, it doesn't lose it's config after a power cycle...
I'm done with Netgear at this point for good.
