Debugging Wifi Connectivity and Routing

Sometimes wifi connectivity issues can be massaged a little by getting a little pushy with it… turn your internal airport card off. Leave it off for a minute then turn it back on and see if by forcing it to attempt to re-connect to your local network.  Oftentimes this will clear up minor issues.

Check your routing tables:

netstat -nr

Get just the default route:

netstat -nr | grep default

In action:

[root@howie ~]$ netstat -nr | grep default
5:default            192.168.1.1        UGSc           11        5     en1
