Device goes offline



  • I don't know if this is related to wifi power saving but my devices go offline and don't respond to pings, ftp requests or requests sent to a simple http server, there are no errors it just goes offline.

    Even when it begins replying again to pings, the http requests are not getting through, I guess the socket died silently and is not able to resume it's lost connection.

    The only way to resume normal state is a restart.

    Anyone else experience this ??



  • Hi, this when it is running as a server listening on a socket:

    Here's the log when it started responding again:

    I (1260162) wifi: pm start, type:1
    

    I don't know if I am reading this correctly but it looks like it put itself to sleep and disassociated itself from the wireless ??
