Hello,
I would like to know if it is possible to restrict secured wireless internet access to specific laptops. Here is the scenario - A co-worker and I have had wireless access for a couple days and after that zilch. We are detecting the network but even after entering the key still cannot get access. I brought a brand new laptop to the office to see if I would be able to detect and connect. I detected it, entered the key and connected successfully. Still no access on the other two aforementioned laptops but other departments have access 24/7. How is this possible?

router or access point recognizes the MAC address of the wireless card in your laptops. A router can be configured to perform specific functions based upon MAC addresses; such as assign the same DHCP address to that MAC address, or deny access to a particular MAC address. Why it worked before and is not working now is another question. If you have access to the router, you'll need to check the logs and the settings to see if those 2 laptops are being blocked.
