No, no other connectivity issues. I know the light should blink but it has become rapid in blinking even when the computers are all off.
Just found a post in dslreports.com about this also.http://www.dslreports.com/forum/r21088493-DIR655-Internet-LED-And-DIR655-now-has-50GHz
so I guess it's just a normal thing now...
never really had this until about a month ago. Light would be on/off/on/off but not such a fast pace.
