DHP-309AV losses connectivity
« on: July 20, 2015, 05:58:30 PM »

I have a power line DHP-309AV in use in my apartment. The incoming router is provided by my ISP (FIOS) the DHP-309AV feeds a DIR 655. The connection generally works fine. But, about once a month it losses connectivity until I unplug the sending unit for an hour, reset it and then it is good for about another month. I am trying to narrow down the reason for the failure. Any thoughts?

We recommend using the DHP after the DIR series router as the main host router should connected right after the main host ISP modem...

  • For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
  • If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. Call the ISP and ask to see if the ISP modem can be bridged. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to or .0.254.
