If you want to surf in internet but find that you can not connect to network, then how to find out what problem is and then solve it? I will tell you how to.
1. First, make sure that your ADSL modem and ISP account are working; otherwise you should ask your ISP for help. If you connect internet through LAN, then test whether you can connect to the gateway. The gateway is a computer or device which connects LAN to Internet or other LAN. You can use command 'ping' to check, but sometimes the gateway turns off its ICMP response. If it does, you can use command 'arp /a' to see all live dynamic MAC addresses stored in memory after ping. If there is a item which belongs to gateway, that means it can be connected, so the physical link is ok.
2. Second, check your DNS setting. DNS means domain name service. If DNS service does not work, you can not open any website when you type domain in browser. Using command 'nslookup' to check whether DNS server works, type some website domain to see if any IP address return. If it works go to the next step, or you should check you DNS setting. Change your DNS server address or ask for technology support.
3. Finally, use command 'tracert' and the website domain or IP address as command argument to see if the path through your PC to the destination IP address is ok, you can watch each hop information through IP packets transfer. If it stopped in a step, then check route setting about this hop, solve it and check again.
