FRC Bridge Configuration Utility Problems

[346Programer]

I have downloaded the utility fine and connected my computer to the router and started the configuration utility. However, when I am supposed to select a network interface, it does not give me any options. I have refreshed a number of times and have changed my IP address around, but it still does not give me any options and I have run out of ideas to get it to work. Please help me with this. Also, sorry if this has already been answered, I am still new to the forums. Thanks.
