Last night I lost internet. ISP contacted (Ziply) and diagnostics were ok on their end. ISP address seems to be reaching the Deco, but nothing getting to devices on the network. Can connect to the Deco web interface but in System -> Time Settings, current time is December 31 1969. Tried firmware load from local bin file downloaded from tplink website. No luck. Traded a different Deco unit (I have 3) to use as main unit and internet was restored. Subnet mask was slightly different, so put back to 255.255.255.0. I ended up rebooting just to be clean but now this 2nd Deco shows it's 1969 again. Some update being pushed is bricking the network, likely due to the system time issue. Tried changing continent/region but no help. I have 1 unit left - not sure I should risk another swap if the same
result happens. Need help.
