DIR-810L good until recently
« on: July 08, 2015, 06:09:33 AM »

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.

ROUTER:  VER: 2.01 / B1   using router wireless
MODEM: Motorola Surfboard SB6121 3.0 CABLE modem
INTERNET:  Cable/ speeds: 50 mbps down

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
