I don't know too much about all the different networking protocols and ways to keep your network safe from hackers, so I hope this makes sense. I have 2 laptops running Windows XP with Broadcom wireless network cards. I am using a wireless router with WPA-PSK security. I can get the laptops to browse the internet fine with WPA-PSK security but have problems getting file sharing to work between the 2. Before I switched to WPA-PSK security from WEP, I had just NWLink IPX/SPX/NetBIOS Compatible Transport Protocol bound to File and Printer Sharing. Once I switched to WPA-PSK security, file sharing stopped working. In order to get it to work again, I had to also bind Internet Protocol (TCP/IP) to File and Printer Sharing.
The reason I believe it had to do this is from what I have read on the internet, a lot of wireless cards don't transfer NetBIOS information through WPA-PSK encryption. However, I have read that binding TCP/IP to File and Printer Sharing is not a good idea for security reasons. So, I was wondering if anybody has any ideas or suggestions on how to make my current wireless network setup better and safer if it isn't already.
