Problem with android connection

Hi all

when I connect me to As400 using the telephone's Router WiFi (telephone is


SAMSUNG therefore Android), it happens that in the case in which for
instance I started

two sessions on As400, the session that I don't use for some

minute go down, while the session that i use is remain active, as if

there pits from some part some timeouts that the session throws down me

not used; if I connect me instead through home's Adsl, always to the

same As400, this doesn't happen.. I Have the suspicion that depends on some


setting of the telephone...

is there someone that can give me some suggestion?

Thanks
