Nah, you don't need to take it anywhere. Just connect a network cable between your PC and the Antminer. This will allow you to communicate with the interface directly to set up the new static ip address.
So I've tried both what you said and taking it to a friends house that is a 192.x.x.x network, their network didn't show the miner as well... I tried connecting the miner directly to my laptops ethernet port as well, and still nothing. I also timed myself holding the "reset" button for a good 240 seconds (4 minutes) before my arms got tired, but no matter how short OR how long I held it, it didn't beep or flash anything differently.
I've also tried re-downloading the stock firmware and put it on a micro SD card, plopped it in and didn't notice anything new/different.
