I have a D-link DAP-1353 n2, I can connect to it fine, but I am not given an IP address. If I assign myself a static IP I can browse the network without any problems. Some other laptops are able to connect and get an IP without any problems.
It seems to be about 50/50 of users that can and can't connect and there is no obvious connection between them. What can I check that might help?
What OS are you using? Maybe the driver is too old for your Laptop WLAN Card/Stick.
Maybe you can try in the command shell:
ipconfig /renew
Checked for Known Issues on D-Link homepage?
I turns out the the router had a date set of something in 1970, I set the date correctly and pointed it at a time server and it now serves the IP addresses as it should.
