I have been searching many posts and still cannot solve this problem after formatting the computer and installing windows xp, all the drivers had to be installed. The ethernet driver was installed as well and it says network is connected. But the problem is that it is sending packets slowly but not receiving any at all. A wireless modem is connected to the router and it is working, it's just the LAN that does not work. I have already tried -turning on 'obtain ip address automatically' and DNS as well. -resetting the router -release and renew ip address from cmd -turning off firewall says dhcp is enabled in ipconfig And i am wondering if having 00-00-00-00-00-00 as the physical address is normal. Please answer this problem!!
