WiFi connecting Issues

[Jay94]

My wi-fi works great at home and whenever I go to McDonalds, but anywhere else my laptop wont connect, even though I have a strong signal and it even troubleshoots to find the problem. Help!

Hi,
do you have the 2 options "Obtain an IP address automatically" and "Obtain DNS server address automatically" selected? Do you know how to select them?
