You shouldn't need to install that software to set up your router. Here's a guide to how to do it through your web browser.

The guide is a bit old, and the setup screens will likely be a bit different because you probably have a different router from the one used in the guide, but the basic idea is the same. Just get into the settings screen and start exploring. Don't be afraid to mess up, because if you do, you can always do a hardware reset.
Hey guys,
I've been out of pocket, but I wanted to come back and thank you for all the help. I used this link, and had the wireless working right away! My ipad2 connected with no problems, and I'm now getting 12 mbs speed. woohoo. I was a bit bummed to discover that I have to buy a wireless adapter to get the Xbox on wifi, but now I can have my Xbox and computer online at the same time. Before, I would have to unplug one port which was a major pain.
I should have done this a long time ago. lol
