I could really use some help. Since I upgraded to Build 1940, I can not access my internet. I have a Macbook Pro and am running Windows XP Professional and Mac OS 10.4.7. I can access shared folders and other features and am using the Bridged Ethernet, default adapter settings for my network adapter. I have gone into the Windows networking and disabled IEEE 802.1x authentication. I do not know what else to do. Can anyone offer some help? Thanks so much.
