Hello!  I've had this router for about a year and a half, and it's been great!  Unfortunately, the internet stopped working on my wired connection a couple of days ago.  Upon inspection, the router's front LED lights were behaving differently.  As the title suggests, the power light stays lit, but the others blink slowly, staying on for a few seconds, then turning off for a few seconds, repeatedly.  I am able to access internet when plugged directly into my modem.  I've tried multiple ethernet cables and they also do not work.  Additionally, our wireless networks are not available - they are not even recognized by our devices.  Has anyone else seen this, and do you have any recommendations?  Thank you!
