Sounds like a configuration problem or MAC problem. Try turning the modem off for a while or clone the PC's MAC. -- Strange as it seems, no amount of learning can cure stupidity, and formal education positively fortifies it. -- Stephen Vizinczey
thanks for your reply. can you please tell me the source and target for cloning? on the MAC address configuration page, there are two fields: "WAN" and "Wireless". Which of these are the target? When I click "Clone PC", it populates the field with an address which is different from what I get when I run ipconfig /all from the cmd window on my windows desktop. I've tried both numbers in both fields (separately) but to no avail.
