I've had my DIR-601 for almost a year now and it's been working near flawlessly until just recently.  I have a very simple setup with a desktop PC, router, Time Warner cable modem, and the only device that accesses the router is my Droid phone.  I shut my PC down every night.  The next day when starting up my PC, there's no internet connection.  I haven't fooled around with any router settings, but what I've been doing to re-connect is unplug the cable modem power cord and router power code, wait a minute, then re-plug them back in and it connects right away.  Is there something easy that I can do/repair to correct this?  Maybe I should check if there are firmware updates?  Or is it a possible hardware issue?  Any help would be appreciated.
