Help setting up Avalon 2

[T68]

*Posted elsewhere on the forum but was told I'd get more help here*

Hello, I'm trying to get my Avalon 2 module set up but I'm having some trouble with the networking side of it. I followed Dogie's guide, but I can't figure out how to set my subnet mask to "0" and I can't access 192.168.0.100 -- the browser says it cannot connect to the page. I have flashed the custom firmware to the WR703N and cgminer is configured with the correct pool information. I just don't know how to change the subnet to 0. If it helps any, ipconfig in cmd turns up my ip's first number as "10"; and whatismyip.com says it is "207", as opposed to the normal "198". Any help would be great. Thanks
