I started my computer yesterday and dialog boxed popped up asking me if I wanted to allow or deny something. I didn't read it and just selected deny. Every since then I haven't been able to connect to any network wirelessly. I still don't have any issues connecting through ethernet, and have tried to reset my modem and router. I have also tried to delete the network and re-add it, manually assign an IP address, delete a couple of com.apple files in the preferences folder, turned off the firewall, and accept all incoming connections in the firewall options, and install / update my Mac and airport all to no avail. Any help would be greatly appreciated.
