thammer: Just another user responding. All that network ID info is stored in the iFly's internal memory, and there does not seem to be an easy, direct way to delete it. There is nothing on the SD card as far as I can determine (remove the SD card and you can still boot up and connect to the network(s)). The only way I have been able to eliminate all the old network ID info is by re-loading the OS. In fact, every time you upgrade to a new OS you will need to re-enter your secure network keys and passwords, etc. Hardly user friendly.The nuisance is that my 720 finds my home network, connects to it, but every so many minutes it goes out and runs down the list of networks it has formerly seen, searching for those other networks and in the process it disconnects me from my home network temporarily then reconnects me (because those other networks are nowhere in range). Meanwhile the browser or WiFi update fails. About all I am able to download successfully is a weather update because it is so short. Seems like once you connect to your preferred local network it should quit hunting around; if it does go hunting it should not disconnect you automatically from the network you are presently connected to; and we should be able to manage the list without having to re-load the OS. ===Ralph
