Wireless IP Address on Virtual Machine

[aaronj2]

I use a vm a lot as I am learning programming.  I am using a Virtual Box vm with a Ubuntu operating system.  However, I can't get an IP address on my home network through my wireless router (dlink 2750b).  The network on the vm is set to bridged adapter so it should be connecting through my host machine, a MacBook.  I haven't had this problem on any other wireless network or even on my home network when I connect my computer to the router directly with an Ethernet cable.  Any ideas would be greatly appreciated as I've played around with the router settings to no avail.

 (I am switching the network settings on the vm to wireless)
