Welcome to BleepingComputer, jaem89. Setting up a wireless network can sometimes be rather complicated. I've programmed for a few years and I've done my small share of DIY hardware projects, including custom-building my desktop, but networking still confuses the crap out of me. There's a very steep learning curve and, since you say you live in an apartment, you may not need wireless. It will certainly save you a few bucks to return that router, and trade it for an inexpensive 'network switch', which is basically a power-strip for a network connection. You can plug a few devices into it, and they can all connect to the internet. Combine that with a few 20-foot cables and you'll save yourself a lot of headaches. I can testify that this particular network switch
works very well to connect 4 devices to the internet.
