 == Trouble shooting & miscellaneous info ==
+After running the experiment, if the dependent variables (ie. kBperS) are all 0, then it's most likely the Wimax BS needs to be configured properly. Please try the following:
+  * Set the BS back to default configuration.[[BR]]
+  * Set the RF attenuator matrix to 0 dB attenuation. Please refer to ''RF Matrix Control Services'' under http://wimax.orbit-lab.org/wiki for more details on changing attenuator values. Many times the attenuator values is set to the maximum (63 dB) in which case the nodes will not be able to with the BS.
