How can I assign IP of my access point Dlink DAP-1150 on my lap top. I want to add adapter network DAP-1150 on my pc

From your computer, get the MAC-address of your network adapter.
Configure the router to always give out the same IP-address for that MAC-address.

That is because your laptop has the saved connection history that you need to delete. Since your acces point does not have security which is not the same as the one that saved from your laptop. Therefore, your laptop won't be able to connect. Go to network and sharing center and from the left side of the page that came up look for change wireless adapter settings and click it. You will be able to see the connections that was saved and the top one would be your connection name. Delete that and close everything. Try connecting to your wireless network again and that should resolve the issue.

I had the same problem with a DLINK DAP-1160, it did not seem to reset and I could not connect, nor PING it. It turned out that the box WAS resetting, and although the default IP address 192.168.0.50 and subnet 255.255.255.0 was being set, my computer was assigning itself up a private IP address and subnet 255.255.0.0. In the manual, it does say that you must be on the same subnet, so I changed my alternate IP address for my ethernet to be static and set the subnet to 255.255.255.0 and everything sprung in to life.

To summarise: make sure the computer you are using to configure the DAP-1160 has its subnet to 255.255.255.0.

just make sure that you belong with in the same IP range.
default DAP-1360 IP is 192.168.0.50
username : admin password : <blank>
change your PC IP address to 192.168.0.xxx (e.g. 192.168.0.2)
from there you may choose wizard or manual configuration.
you may change your DAP-1360 IP add according to your network settings in the office and you must change you PC IP address with in the same range.

Reset the device, unplug all network cable before power on (to turn off dhcp function). After that connect the network cablethe ip device should 192.168.0.50 and subnet mask 255.255.255.0. Set your computer ip address to 192.168.0.xxx where xxx is not 50. Access the device via your web browser, the login page should be apear. User : admin, password : leave it blank

The DLink URL WEB configuration uses an IP address not //dlinkap
Try http://192.168.0.1
The default ligin = admin
The default PW = blank ie. nothing

Hi. Is this to change its settings?

Plug directly in the DAP-1522.
Set your PCs network settings under TCP/IP, alternate config:
IP Address: 192.168.0.10
Subnet mask: 255.255.255.0
Default Gateway: 192.168.0.50

Give it a try.
Regards,

address to access d-link DAP-1150
http://192.168.0.50

you have to make sure that your ip address is around 192.168.0.xx

Open a web browser and type http://192.168.0.1 in the address bar.
Enter admin for the username and no password to get into setup.
