I'm using Dell laptop both at home and work. I have Xircom NIC installed with TCP/IP binded to it. IP address set to obtain automatically, DNS disabled and for WINS it is using DHCP Server. At work everything works fine, but when I get home and hook it to my home network (DSL router connected to the switch, and all computers are connected to that switch), all computers work and configuration is identical on all of them, but not laptop. I think I've tried anything I could think about, but still no luck at all. Any ideas ?
