Hello, if I connect my cellphone to a particular wifi network (SSID) and then leave the cellphone unattended for a while, I find that when I go back it has switched to a new wifi network (SSID). Is this normal behaviour with cellphones i.e. they will disconnect if no activity or a stronger network found ? Have you guys experienced this ? and if so do you know why ?
Yes that is normal. It will connect to the "best" network, and the only way it has to tell bestness before connecting is signal strength. There is no ordering of them on android like on a windows computer. Not sure about ios as I limit my exposure to that to only when nessacary.
If the crap network is stronger, it will connect to it.
