Goto network settings, change adapter settings, right click on wireless connection 3, properties, networking tab, left click on internet protocol version 4 (not 6!), click on properties. Make sure the following are both checked: obtain an ip address automatically, obtain dns server address automatically. Click on ok and back out. These will make your wireless adapter run DHCP to get an ip address from your router. If still no success then you will need to ensure that your router is set to run dchp and exactly how to do this varies from one router to another but it should normally default to that so just resetting the router should do it for you.
