Try to see if the wifi is active (there are simple wifi scanners such as inSSIDer that might help http://www.metageek.net/products/inssider/). Can you swap the control board with a known working Ant?
If you are trying to run it standalone against a PC, you should set the PC temporarily to a fixed IP in the same space as the Ant and connect them with a crossover cable, or through a hub/switch. An ethernet switch would give you a clue if the connection is alive through the status lights of the port that the Ant is connected to. If all else fails, try to contact Bitmain (see email addresses at https://www.bitmaintech.com/about.htm)
Good luck
i know that it is not seen via the ip pfsnece is not picking it up
ive scanned the ip range and tested a couple of other common ip router ranges.
the switch is showing that it is connected.
i have contacted bitmain with no luck.
