I have two computers networked through a wireless router:
The Linksys BEFW11S4 wireless router is attached to my desktop PC. My laptop accesses the network and internet through a Microsoft MN-520 Wireless Notebook adapter. Both computers also have Trend Micro Internet Security installed. Everything worked fine until I updated Windows XP to install Service Pack 2 on both computers. Now, I can no longer access the internet or shared files from the laptop and I cannot access shared files residing on the laptop from the desktop PC. Here's the sequence of events:
1. Installed Service Pack 2 on Desktop PC. Laptop can access internet but can not see or share files from the Desktop PC.
2. Installed Service Pack 2 on the Laptop. The laptop can no longer access the internet or access shared files from the Desktop PC.
I turned off Windows firewall, left the Trend Micro firewall on.
Help is appreciated!
