Wifi connection but no internet
Your wireless device appears to be in promiscuous mode.  Maybe you are doing a packet dump or sniffing packets?  If so, no worries.  If not, I would investigate this further, as it sometimes yet not always indicates a compromised system being used as a stepping stone in further network penetration.  

First, a quick and dirty network device refresh can be effectuated by creating a new location in the System Preferences, under the network portion.  Look at the top, and under location, click edit locations.  Then click the plus button, and give the new location a name.
Then please select your home network, and re-enter the password.  

Your problem might have been resolved.  If not, then please go back to the terminal and provide the output of these:

     ifconfig -a -v

     pfctl -v -si

     pfctl -v -sr

     ipconfig getpacket en1

     netstat -nvia -I en1

     netstat -nr


Hope that this helps.
