You may have a wireless signal, but you sure as hell ain't got a proper network connection!
You do not have DHCP enabled - yet you have no gateway configured, nor have you any DNS servers listed. In fact, the fixed IP address you have is almost certainly the same as the wifi router!
Either switch ON DHCP, or supply the correct information manually - node IP address (subnet mask is correct), gateway address (router address) and DNS server addresses.
Otherwise you would never see anything on the network!
Here's mine, for example:
