Question about D-Link AirPlus DI-524 Wireless Router

After replacing Cable Modem, D-Link DI-524 Wireless will not work

I replaced my Cable Modem with a Motorola SB5101 SURFboard cable modem. I hace Comcast High Speed Internet. I connected everything properly to my D-Link DI-524 Wireless Router. I cannot access the internet with my laptop now unless i am plugged into the back of the Router with an Ethernet Cable. The Status light is also not on on the router. If I plug into the Router, i can surf just fine. I went into the configuration and checked all the settings. I also made sure that my IP Address was set to load from the DHCP. I have tried to remove the WEP 128-bit security, but that did not change anything. I also reset my router using the reset button, still, no wireless connection. It was working just fine yesterday before the Modem was changed. Obviously the modem works well since i can connect by plugging into the Ethernet port. My laptop is a Compaq Presario CQ50, running Vista, here is a copy of ipconfig:

I am completely at a loss and figure that i am missing something stupid. I would be eternally grateful if anyone can offer assistance!

    For Solution #2, I called Comcast on the way home from the store with the new Router. I am actually an IS person, it has just been a long time since I have dealt with a stubborn Router. The MAC address is loaded correctly since I am able to successfully connect to the internet.

    Connect the Cable modem to the router's Internet/WAN port, then connect the PC to any one of the router's ports.
    Reset the D-Link router:
    D-Link Router reset
    Step 1 Locate the reset pinhole on the back of the unit.
    Step 2 With the unit powered on, press and hold the Reset button.
    Step 3 Hold the Reset button for about 10 seconds.
    Step 4 Release the Reset button.
    Step 5 The unit will reboot. Allow 20-30 seconds before reconnecting.
    Step 6 The device is now at factory defaults.
    Note: Do not recycle power during the reset procedure. The default user name for most D-Link devices is admin and the password is left blank.
    When it says hold for about 10 seconds, don't hold for more than ten seconds or the procedure will likely fail, if ten seconds doesn't work try 5 seconds. Then:

    Shutdown your PC. Unplug the power from the router and the cable modem.
    Wait 30 sec. then plug in the power to the cable modem, wait 30 sec. then plug the power to the router. Wait till you have "Internet" light then restart your PC. The PC should pick up an IP address and you should be able to get on-line. This is if you have a cable service provider. If you have DSL, the router needs to be configured with PPOe.
    If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
    Thanks, Joe

    Your ipconfig looks so good. Try to ping the router if you can get for 4 lines with a good communication indication. Or check if the router's is broadcasting, could be SSID, or DNS settings.

Did you call Comcast and give them the new MAC address of the Motorola SB5101 SURFboard cable modem? I'm surpised it works at all without doing this first. This is the hardware address of your modem so the world can see you, no one in the world has the same MAC address, they are all different. It's on a sticker on the modem.

Hi Serina - first of all: what a great post! Very detailed and professional. I just have to say that, since I'm reading here lots of "interesting" questions sometimes.

To your problem:
Apparenatly the router does the "routing" part well, since you can access the internet via cable. The problem is the wireless access point.
Your IP output looks actually good - I can't see any problems with the values. What I would try to do is to disable IPv6, since it is only used on your internal LAN and not yet implemented on the WAN side. This page (link) has a good write-up on the how-to. Don't do the registry part - just disable it in the Properties window.

I had noticed conflicts on computers where IPv4 and v6 were installed simultaniously.

Try it and see if that corrects the problem. If it does not, please let me know.If you have any more questions, just come back here and leave a comment - I'm happy to help.

I cant get my motorola sb5101 surf board cable modem to connect to a belkin g wireless router. the light on the belkin flashes orange when i try to connect it to the modem but no internet connection

I have a similar problem. The common denominator seems to be the SB5101. I have a brand new Belkin Surf 300N, same issue. The modem will not give DHCP to the router. I can connect fine via ethernet to the modem directly.
This modem seems to be a dinosaur.

How to connect my motorola surfboard sb5101 cable modem ot my ps3

Hi turn both modem and PS3 off. Then connect the ethernet cable from the modem to the PS3 and then turn the PS3 first. Then after the PS3 is completely on, then turn the modem on so the PS3 will get the modem's IP adress.
I recommend you get a router and connect it to the modem and the PS3 to the router. It's way better. I hope this helps.
