Can't connect arduino to wifi

I'm new to arduino so my question may sound stupid. I bought a wifi shield which says that the chip is RN-171 I/RM. I followed this tutorial: http://cairohackerspace.blogspot.co.il/2011/05/beginners-guide-to-connecting-and.html Here's my init function:

boolean initSettings()
{
  wifi.SendCommand("set wlan auth 4",">",bufRequest, REQUEST_BUFFER_SIZE);
  //wifi.SendCommand("set wlan key <value>","AOK",bufRequest, REQUEST_BUFFER_SIZE);
  wifi.SendCommand("set wlan channel 0",">",bufRequest, REQUEST_BUFFER_SIZE);
  wifi.SendCommand("set wlan join 1",">",bufRequest, REQUEST_BUFFER_SIZE);
  wifi.SendCommand("set dhcp 1",">",bufRequest, REQUEST_BUFFER_SIZE);
  wifi.SendCommand("save",">",bufRequest, REQUEST_BUFFER_SIZE);
  wifi.SendCommand("reboot",">",bufRequest, REQUEST_BUFFER_SIZE);
}

And I have my credentials configured in the Credentials.h file. When I run this code, I get the following output:

It continues endlessly, and I can't access the arduino through the ip and port, it results in an endless spinner...

Can anybody help? Thank you.
