So I have an AEBS that's about 1.5 yrs old. I really like the guest sharing application for a current set up I'd like to make, but I realize that it's not available with my model. Essentially, there is someone that lives in the apartment below me that wants to share the internet with me. I could use the extra cash, but I have all my media and data connected to my AEBS. Now I realize that you can password protect your HDs (which I do) but I really just don't want my neighbor on my network. Are there any alternatives? I have an old 802.11g Airport Express that I was going to connect wirelessly to the AEBS so my printer could connect to it, so that may be an option. What set ups or suggestions do you all have?
