At live events with 20+ wifi signals, I often find I can't get my iOS devices (iPod Touch and iPad) to stay connected to my wireless networks.
Simply put, the devices connect and have reasonable signal strength + bandwidth, but after an indeterminate amount of time (sometimes 30 seconds, or times 3 hours), the iDevice completely disconnects from the wireless network.
I have three wireless networks, all are 2.4ghz + 5ghz; auto-negotiate for channel and all are secured with WPA2.
Would I be better off using a wireless SSID that broadcasts a local network, but then routes the traffic over the LAN? On the face of it, that question seems to be what wireless does anyways?
I've performed some wireless analysis using Mountain Lion's Wirless Diagnostics utility. It looks like channel 11 is actually fairly free, so I have switched from auto (which had me on a heavily polluted channel) and moved to one that is hopefully less busy.
There are 194 wireless radios within range of my wireless routers. Is there any way to determine how much of an issue that could be?
