There is my problem description: My PC is connected to the Internet by cable modem, that is connected to the router (SMC Barricade SMCWBR14S-N2). I have Windows XP Prof. SP3, 2 network adapters onboard (nVidia and Realtek). All other PC connected through that router have no problems, and so did I until yesterday. Suddenly, I was disconnected and now cannot connect to the router. - if I try to set get IP automatically by DHCP (router log says "sending OFFER to 192.168.1.10"), no valid address is obtained (only 169.254.*.*). - if I set the IP manually, computer seems connected, but there's no response to pinging 192.168.1.1 - I tried turn off firewall and antivirus (ESET Smart Security)- no effect - I also tried to reset winsock with netsh, but no luck - then I tried to connect the PC to some other computer directly by crossed UTP and connection was working correctly Does anyone know, what should I do?
