DHCP Relay on de DIR-810L
« on: December 22, 2014, 12:12:22 PM »

Hello,

I buyed the DIR-810L some days ago because my old access point broke up.
My ISP Router have an integrated Switch with DHCP but i'm unable to broadcast the informationes over the DIR-810L Router...
So my ISP Router isn't connected on the WAN Port, only to the LAN Port...

Is this configuration not possible?
Or may i can add some Gateway to the DHCP for the Wireless clients that my ISP Router is the Gateway?

I have Hardware Version: A1 Firmware Version: 1.01
Region Europe (Switzerland)
Thanks a lot

Hi,

if I understand your scenario right, you want to use the DIR-810L device as a replacement for your broken access point. Typically an access point has no routing function but only bridges WiFi frames to wired LAN. Hence if you want to operate your DIR-810L the same way, you can't use it as a router but have to use it as a bridge. You do this by not using its WAN port to connect to your ISP router, but use a LAN port instead. Switch off DHCP server function on DIR-810L, and for its LAN interface configure an address out of the network defined by your ISP router (don't use an address out of the DHCP pool, defined by your ISP router but from the network range that is not covered by the DHCP pool and hence is reserved for static configurations of devices in this network). You don't have to configure your DIR-810L for Internet access, it is just an additional switch that enhances your wired network and an access points that connects (bridges) wireless clients to the wired network.

Link>Welcome!

  • 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.

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
  • What ISP Modem service link speeds UP and Down do you have?
  • 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
  • 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. 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 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.
    Example of a D-Link router configured for PPPoE with ISP Modem bridged: PPPoE Configuration on Router

Are you connecting to the DIR wireless or a different wireless?

I've solved the problem...
My Netopia-7000 Swisscom Router broke up step by step...
With luck a friend of mine had an other one and now everything works fine...

Bad luck that my older AP and my Router at same time brokes up...

thanks for help
