Arduino.local not working...HELP PLEASE!!

I am trying to connect my Arduino Yun to the internet either via WiFi or a Ethernet Cable. Preferably by WiFi.

  1. My first problem:

"When you first power on the Yún, it will create a WiFi network called ArduinoYun-XXXXXXXXXXXX. Connect your computer to this network."

I have no network called ArduinoYun-XXXXXXXXXXXX,when I power my Arduino and its bugging me.

  1. I abandoned the idea of using WiFi and resorted to Ethernet cable. But I cant turn my computer into a static IP address (I dont know why) or as a DHCP server.

What should I do????

Is there a simpler way I just don't know about? I am a beginner in Arduino.

Please help!
