Hey guys, I purchased an Airport Extreme tonight and I got a bad case of buyers remorse. Basically, I live in an apartment and feel like it is unnecessary. I won't use the other Ethernet ports as everything I have is wireless. I bought this for the hard drive capability, more options in regards to setting up connections and the simultaneous dual band range (2.4 and 5 ghz). These perks are nice to have. What really got me to choose the Airport Extreme over the Express was that my unit happens to be in front of the street next to the garage door. I heard that the radio signals from the garage door could interfere and cause some disruption to my internet connection. How severe or how much difference does that really make? Should I keep it or swap it back tomorrow at the store for an Express or for a different router? Thanks!
