I have set up quite a few (simple) Airport networks in my life. Well, setup might not be the right wording; attaching a couple of Airport Expresses into the power, launch Airport Utility and go. Now I'd like to implement a larger network of about 20 APEs in a hotel environment. For having good wireless connectivity around a property, but also to be able to stream music in every room. My questions are - Is this amount of access points feasible? - What are the caveats? - How does the Airport handles the frequencies / channeling? - Would a couple Airplay streams cough up the entire network? - Can I go for wireless only or do I need some cabling? The last question is quite important. In the past I tried to wire up APE's, treating them as normal access points (LAN in, WLAN out). No matter what I tried, all APE's ended up being wireless repeaters rather than getting source signal from the LAN cable. Any suggestions, ideas or real life experience are greatly appreciated!
