Cannot connect to wireless network

Hello,

I cannot connect my netbook to a wireless network. Or, I should say, I can connect to the network, but not to the internet. A previuos thread (now closed) suggested

"1) 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"

I turned off the firewall, but call be dumb nowhere can I find the place to check my TCP/IP properties. I clicked on the adapter and went to properties...shouldn't it be there?

Any help would be appreciated and please excuse my idiocy LOL
