I turn off the pwoer stick for my Motorola cable modem and rotuer every night before I go to sleep to save some electricity.
When I turn it back on, routerr will not reconnect to the modem automatically. I have to recycle the power switch on the router or disconnect and reconnect the rotuer to modem ethernet cable to get them to talk again.
I bought he N900 a week ago and it is a daily occurence. My previous D-Link would come back on and reconnect immediately.
Other than that, I like the router.
