iPhone won't connect to internet
Apparently, DHCP is not enabled on your laptop, but it has the right configuration, so I figure either DHCP must have been disabled on your router recently, or your phone was configured with static addresses which got cleared recently.

For a quick fix, try filling in the Router, IP address, and subnet mask fields on your phone after choosing Manual for "Configure IP". Something like:

Configure IP: Manual  
IP address: 192.168.1.123  
Subnet Mask: 255.255.255.0  
Router: 192.168.1.1  


But you probably want to fix the settings on your router so you don't have to configure every device that connects to your network in the future.

Look for a setting that enables DHCP in your router's administrative interface, possibly on http://192.168.1.1
