I learned though Trial and Error. Started our wireless using a linksys 854G with linksys stock, worked with 4 or 5 of us when we first moved into the still under construction building, worked till the owner bought his sono's setup and installed it in his office, both gyms, conference room. Kept locking up, upgraded to DD-WRT and that fixed it till 4 more people moved in, but our fiber wired network was in by then so the wireless went on the back burner. Then the iphones arrived and it became an issue again. I upgraded to Cisco 891W but cheaped out on the WAPS, Cisco WAP610's, the waps would just stop working once lunch time arrived and the workers hooked up in the lunch room, no problem as long as you were in range of the 891W in my computer room, light bulb went off, ordered 2 Aeronet 1600E SAP [stand alone points], one in the lunch room, one to learn with and it handled the lunch crowd, more important the owner could sit in the lunch room and use his iPad. Had our first big customer event with ~1500 in attendance, put up another 891W Wan'd by a 80MB cable modem and 4 aeronets poe'd from the 891 spread out over 2 acres under a big circus type tent, worked with no issues and no customer complaints, had 4 vlans, one secure, 3 open with 4 dhcp scopes. The options, features and control on the aeronet 1600's were mind boggling from what I was used to on consumer waps. When I got the first aeronet I literally spent 2 days reading and trying till I got what I wanted and I still don't use all the features.
