I am connected to a wireless network some 500 meters distant using a wireless pci adapter with an external antenna. My system is windows xp professional 'new' edition. I originally set this up using a qpcom wireless pci adapter 802.11g. Due to the weak signal that I received, I changed the wireless pci adapter to a D-Link 802.11b which improved the signal tremendously. Of course I had to use the same ip information. Now I am receiving messages that I have a possible ip conflict. How do I correct this situation?
