Ubuntu 12.04 host – Virtualbox 4.1.12 Guest=Windows 7 – Network will not connect.

I'm using Ubuntu 12.04 on an Acer Aspire 5742-7645 laptop with 4GB memory, Intel Core i3 processor, Intel HD Graphics, DVD drive, 802.1 b/g/n, and 500 GB HD. I connect to my router via a wireless connection.

I have installed Virutalbox 4.1.12 from the Ubuntu Software Center and installed Guest additions 4.1.12 in the Windows 7 guest session.

I have Windows XP and Windows 7 installed as guests in Virtual box The network settings are different for XP and 7 – see below. Network Settings XP guest = Adapter 1: PCnet-FAST III (NAT) - Network works perfectly and has worked well for several years.

Network Settings Win 7 = Adapter 1: Intel PRO/1000 MT Desktop (Bridged adapter, eth1) Promiscuous Mode = allow all Cable connected = checked

When I originally installed Windows 7, I tried NAT and the guest network would not connect. Once I changed the setting to the above (Bridged) the Network worked perfectly. However, what I believe is after updates (not sure if it was an Ubuntu or Windows update) the guest network stopped working and I can not get it to connect.

I'm not sure what else to do. Can someone provide the troubleshooting steps to determine what the problem is and possible solution?
