After I installed DI-524UP router, I lost access to my LAN, i.e. to other computers, earlier it worked fine with linksys router. I can access Internet from any PC from my lan, but no access to other PCs. I have set up home network a few times(all XP computers), sharing and necessary protocols are enabled, but the problem still remains. Anyone has an idea what might be causing this problem? I have a few "normal" desktops and couple of wireless notebook in my lan.
