The issue I'd say is the IP address that your wireless "isn't" getting. A 169.254.161.124 address is a default IP that the system generates when it can't get an IP address from the network connection that's established. Has this wireless connection ever worked on this computer? If it has and suddenly stopped working, then you can delete that connection (not the wireless adapter, but the connection) and then the next time you attempt to connect it will ask for the security key (if you're running security) and then all should be well.
From time to time, we have been tempted to believe that society has become too complex to be managed by self-rule, that government by an elite group is superior to government for, by, and of the people. But if no one among us is capable of governing himself, then who among us has the capacity to govern someone else?
