DIR-815 is not connected
« on: July 09, 2015, 04:28:03 AM »


I had to re-arrange and before everything was working fine and now my router is disconnected. I have the SurfBoard SB5101 and I have a Dlink DIR-815 router and my PC is a PC that was built so it does not have a proper brand and/or model.

This is how I have it connected. From SB5101-->DIR-815 to the blue 1 port using the blue cable than DIR-815-->PC and on the router it is the internet port using the white cable.

I tried to ping in CMD but it failed. General failure.

I also tried the troubleshooting in Windows, but Local Area Connection doesn't have a valid IP configuration.

Any help I would appreciate. Thank you,

  • What Hardware version is your router? Look at sticker under the router case.
  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?
  • Are you wired or wireless connected to the router?
  • Has a Factory Reset been performed?
  • Was a Factory Reset performed before and after any firmware updates then set up from scratch?
  Link> >FW Update Process
  • Was the router working before any firmware updates?
Internet Service Provider and Modem Configurations
  • What ISP Modem service link speeds UP and Down do you have? Link> Speed Testing Sites
  • By-pass the main host router and check internet connection by connecting a wired LAN PC directly to the ISP modem to verify connection access and ISP speeds.
  • Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
  • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
