    Greetings!
    I will try to keep this short.
    My current Setup:
    Main Router:
    Model : Bell Canada Connection Hub
    SSID : Wifi 1
    Security : WAP2
    Gateway : 192.168.2.1
    Subset Mask : 255.255.255.0
    DHCP : On
    IP Range: 192.168.2.10 to 192.168.2.254

    Access Point:
    Model : D-LINK DIR-820L
    SSID : Wifi 1
    Security : Same as Router (same SSID and password)
    Gateway : Was 192.168.0.1 but is now inaccessible
    No Static IP Address (may be a problem)
    DHCP : Off
    The moment I turned DHCP off, I was not able to access the Config page of the AP anymore.

    So here is my problem, all I wanted to do was being able to Port Foward, but behind two routers it gets pretty hard. So I turned my D-Link into an AP to be able to port foward easily.
    My Mother's iPhone and my OnePlus One are connected to Wifi 1 without any issue.
    But any "new" cellphone or laptop get stuck at "Obtaining IP Address...", "Authenticating..." or "Limited Access"

    I also tried to rename the Main Router SSID to Wifi 2, still can't connect to either Wifi 1 (D-link) or Wifi 2 (Hub).
    I feel like I have missed something, I can Factory Reset the D-Link as much as I want but not with the Bell Hub.

    In my Port Foward I only have 3 open Ports:
    WoL (wake on lan): Protocol UDP, port 9 on the IP address 192.168.2.254 (Broadcast)
    WoL2: Protocol UDP, Port 7 on the Static IP Address of my Main Computer : 192.168.2.28 which is plugged in the LAN Port 1 of the D-Link.
    And Minecraft, port 25565 on my Main Computer.
    I Also noticed that my ISP does not support Port Foward Loop Back (Can't connect to my own External IP address in Minecraft, I have to use my IPv4)

    Thank you in Advance!

    First, if you can't access the D-Link's config pages now you skipped a step or two in setting it up.

    JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers" is a computer.] Leave the WAN port unconnected! [TerryNet Note: assume that all routers made in the last five or six years or more have auto-sensing ports.]

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
