I'm have a D-Link DIR-615 Wireless N 300 Router. I didn't use the CD it comes with to set up the network. Instead I configured it manually through the router's settings that are accessed via a web browser.
The main changes I made are:
- Secured the router so that a password is required before clients can use the wireless internet.
- Broadcasting 802.11N only (not B or G).
I can connect to the router just fine and I'm able to access the internet. The only problem is that I don't see any of the other computers in my LAN. When I try connecting to another Wi-Fi router that I have (which is connected to the same network), I can see all of the computer's on my LAN just fine. Therefore, I'm guessing that the reason I can't connect to the LAN is not a problem with my computer and is a problem with the router instead.
I'm on a MacBook Air running Mac OS X 10.6.6.
I tried contacting D-Link technical support, but they only try to help you if you have problems connecting to the internet. They aren't really concerned with problems that have to do with the accessing PC's on the same network.
