Configuring a D-Link DIR 655 as a pure access point

Ok, so this hasn't really anything to do with any Oracle technology, but it's part of my ongoing network configuration and I couldn't find a real simple guide to do this. I have a D-Link DIR 655 wireless router which used to connect to the Comcast cable modem and handle all the traffic into and out of my local network. However i've since deployed pfSense and untangle leaving the DIR to only handle my wireless requirements.

So my requirement now was to have the DIR 655 only handle the wireless network and allow clients to connect to the LAN network, basically it becomes just an access point. This is simple to do and i've taken a few screen shots for clarity. There may be differences depending on your firmware, but the theory is the same and could also apply to other similar wireless routers.

Oh and one more thing, ALL network numbers and mac addresses on the screen shots have been changed for obvious reasons.

    First make sure you understand how to connect to the admin interface of the DIR when making changes. I've never bothered to connect via the USB port, instead I do everything via the web interface. This means that I have enabled remote administration so that I can access the router on either the LAN or WAN interface. For the total newb, I should explain the difference between the two interfaces.

    • WAN (Wide Area Network) refers to the network beyond your home system. Typically this is the Internet and you connect to it via the WAN port on the router that connects to your internet provider. This takes the form of an Ethernet connection.
    • LAN (Local Area Network) refers to your network of desktops and laptops that are local to you, i.e. the ones in my house. On the DIR 655 there are 4 LAN ports, again they are Ethernet connections.

    So the following is a screen shot of making sure that you can connect to the router via the WAN interface in case you need to.

  • Next setup the WAN interface to a static address that doesn't really get used because we are not going to be connecting it to anything.

    1. Login to the router web interface as admin and click on SETUP
    2. Select "INTERNET" from the menu on the left
    3. Select "Manual Internet Connection Setup"
    4. Choose "Static IP" for "My Internet Connection is..."
    5. Enter in some non used network information like the screen shot below. I'm not sure if it matters if these values conflict with any numbers on your local network because nothing will be connected to the port anyway, but I play safe and have use a network that doesn't exist on my LAN.

  • Next setup the LAN information. I use the DHCP server on my pfSense device to configure the addressing for my clients and I only want the DIR to handle connecting wireless clients to my local subnet.

    1. Login to the router web interface as admin and click on SETUP
    2. Select "NETWORK SETTINGS" from the menu on the left
    3. Deselect the "Enable DHCP Server" check box
    4. Now enter in the network values for your LAN. You will need to specify a "Router IP address" and this is what you will use to connect and administrate the router. There is a good chance this is already setup correctly. It is good practice to give this interface a number very high on the subnet. Again have a look at the screen shot below for what i've got setup.

  • Finally the most important piece, take an Ethernet cable from the LAN switch/hub (I hope people don't still use hubs!) and stick it into any one of the 4 LAN ports on the router. By doing this you have now made the wireless network and extension of your LAN network. Any broadcast packets will also reach onto the wireless network. So now any wireless client is going to get a DHCP address from my pfSense device and I can communicate using protocols such as Bonjour.

Thanx for this. I'm looking at basically the same setup and wanted to check that it was indeed doable. Cheers! :)

Hi Simon, thank you for this Tip ! I only have access to a Wireless Access provider in my area and it works fine as long as a use my built-in Wireless Nic#1 (HP Slimline 7112). Still, I can not make the D-655 work as a " Point of Access" when trying to use the Ethernet Nic#2 (Nic#1deactivated) and 1 Lan port of the 655 ! ...(Website not found) Aren' t we suposed to set up a routing feature of the 655 to redirect a LAN request from the 655 Gateway to the final remote Wireless Providor's Gateway ? (Acess Provider is using Wifi without Wep/Wap and a fixed IP.) (Dir-655 A1/A2 firm. 1.21)

Thank you so much for the tip. My dealer was unable to help. Your setup worked perfectly

By far the best description I've found of turning a DIR-655 into an AP. It got me most of the way there. The caveat: I was not initially aware that the MAC filtering affected both the WLAN and LAN! Don't turn on MAC filtering unless you are prepared to do the LAN side, too. Otherwise you can't get to the other router's gateway for DHCP.

This was hugely useful--thank you! We spent several hours this weekend trying to figure out how to do this.

as i understand it, your DIR-655 needs to be wired to the LAN. i.e. the DIR-655 doesn't support functioning as an AP while itself being connected via WIfi. Is that correct? My googling seems to indicate so. -a

Thanks a lot it works perfectly :D Big <3 !

Instructions were very helpful. Had to take my Qwest router off the net since it was using same ip as new router. I use low end addresses for network components and servers. Anyone have experience using 655 in place of Qwest Actiontech?

This is AWESOME. I just had Comcast installed and I didn't know what to do with my DIR-655 router. Thank you so much!

Thank you very much. I've used about 20 hours setting up this network, with no luck... until reading your article about this very subject. Thank you very much. You rock!!

Perfect guide - thanks a lot. Configuration done in a few minutes!
