DIR-625 Blocking DWL-G510 connection

I had my wireless network working for my 10 years old computer on the 3rd floor. My Wireless router is in the basement along with my 2nd computer. I just brought a new computer to replace the 10 years old one. So I remove the network adapter from old comp and put it into the new one. The drivers were up-to-date and installed correctly. I see connectivity bars and entered the correct password. However the connection process never reaches the point of acquiring ip address. It just stay at trying to connect and never connect. I reinstall every drivers, move the adapter to another PCI slot, reboot wireless router, checked firewall connection. This computer does work for wired connection.
I did notice that the router is BLOCKING the TCP connection from my computer. The weird part is why does it only block this connection, but for my other wireless laptop it worked. Also this adapter worked for my old computer but not new one? I read other forums here stating that the router may block some MAC adresss. Well how do I unblock it? I thought it was suppose to be plug and play and if you enter the correct WPA key, (like how I do with all my other wireless) that it should work.
Also I noticed that the Dlink connection wizard has error for the new computer and doesn't open. So I used windows wizard to connect wirelessly.

Computer Spec:
Asus P5N-MX mobo
Dlink DWL-G510 wireless (rev. B)
Intel Dual Core E5200
Window XP service pack 3

    having same issue; laptop connects fine to dir-615, but another xp-home pc with xp-sp2 that connects to dir-615 with dwl-G510 card will not connect to the router. Have all updated firmwire! Any suggestions. Protocol is WEP with shared access on key 1.

    I have the same problem. I can connect wirelessly with two computers but then my laptop is blocked when checking the logs. However, if I turn off one of the computers, all of a sudden, my laptop can connect. So I was thinking that maybe the dir-625, can only support a maximum of two wireless connections. I have checked in the settings and can't find a place to raise that number, even if that is possible. Can anyone confirm if this is the answer?

    P.S. For the solution #1, I have the updated firmware and drivers, and mac filtering is off. So that didn't solve anything.

Are you trying to connect to the wireless network ?
You are using windows XP computer. and you have D-link adapter.
In case of windows XP computer there is built in utility to connect to the wireless network. and also you have Dlink utility to connect to the wireless network.
It will be better to use the Windows utility to connect to the wireless network.
Search for the wireless network and you will see your wireless network. I believe you have the wireless router.

Use with dwl-2100ap

What you need to do is configure the dwl-2100AP. You need to login into the repeater's configuration page and go to Home tab, click on wireless on the left. Select AP Repeater under Mode. A new screen will show up. Click on the scan button to see if your router's signal is being picked up in the box. Just select the signal if you see it in the box and put in your security info if you have one.
