During last night's IOP, the users were having to cycle power to the Netgear WiFi box every 15min because of dropped connections. As a test, I have been running today using WiFi for more than 2 hours straight. Nevertheless, I just decided to change the WPA "key lifetime" from 60 -> 120 minutes. Perhaps this will keep the connection going longer?
Obviously, the other logical conclusion is that RF interference from things like the tethersonde that only operate during IOPs might be the source of poor connections?
