DIR-810L purchased on 6/24/2015. Was working flawlessly until 2 days ago. first incident orange power light came on (middle of night), Modem working was okay, only router down. After, unplugging modem, resetting router, starting from scratch worked great during day. Next incident Router completely shut down, middle of night, modem okay. This never happened before, until recently. I plugged in old D-link router - DIR-605L works good. But, no longer can get DIR-810L to stay on, I tried different outlets, power strip, etc. Same thing and it all happens in the middle of the night. Also, may add, the DIR-810L was new when I purchased.
