network ok but no internet

OpenDNS servers:
DNS1: 208.67.222.222
DNS2: 208.67.220.220
Turn off your firewall
2) Open your "wireless adapater" properties, make sure your "TCP/IP properties" have "Automatically assigned by DHCP" everywhere
3) If the above steps didn't bring any light, then open "Status" for your "Wireless connection", write down your IP address (the first line), network mask, gateway address and DNS servers addresses
4) Disable your "wireless adapter", open its properties, change "TCP/IP properties" to the written down information, change the places of DNS server with written one, so that DNS1 will be DNS2 and DNS2 will be DNS1
5) Enable your "wireless adapter" and try google
ipconfig /releasel
ipconfig /all
ipconfig /flushdns
ipconfig /renew
