I have a Netgear wireless router. If my iPhone gets connected to that MB will not connect to the router (will say connection time out). If iPhone is disconnected MB connects right away.
Try manually adding the Macbook MAC address to allowed computers on the router. I was having a similar problem in a office I was contracted out to, and this solved my macbook connectivity issue.

Do you have conflicting static IPs? Might want to make sure DHCP is on, has a sufficient range (re: enough free IPs), and DHCP is enabled on both the Macbook and the iPhone.
