in UP Board Android

I have two Up boards with ubilinux. I have tried the Realtek and the UP-Store wireless dongle. Both exhibit the same problem. They will both show a connection as per Connman, but will not transmit or receive data after a very short period (2 minutes). I have to use connman to disconnect the wireless, then re-connec it. It works for 2 minutes then drops the service.
Anyone else have this problem?

    Hi CliffR,

    Could you please PM me the output of this troubleshooting script (while the dongle is plugged in)?

    Not sure why I did not get an email notification of your response. I would have answered immediately. I'll make sure profile is correct.

    I am on another network now and am not experiencing drops. Possibly the wifi is stable on secure networks (password auth). The previous network with the wifi dropping had no security.

    I did a fresh install of ubilinux with update and upgrade on UpBoard. The wifi adapter still fails after a short period of time and needs to be restarted with Conman. This is a serious issue. Attached is the debug log as requested. I did get an error from the debug script but do not know if it is important: tail: cannot open '/sys/kernel/debug/regmap/AA/' for reading: No such file or directory

    I had to restart the wifi during this comment.....

    Please assist. Thank you,
    Cliff

    ENet interface does not fail. A continuous ping from the board to my router will keep the wifi connection alive. Shorty after stopping the ping, or after no activity on FireFox, the wifi will die. I have to restart in Conman. About 30% of the received packets are discarded. I turned off power saving using the desktop tool, I'm not sure how to verify, as it still goes into screen saver.

    OK, I have a solution. I am on ubilinux on the UpBoard. DO NOT use a Realtek or the UPBoard store wireless dongle. They will drop connections on some networks. I tested several other dongles, and the "Panda Wireless Mini Wifi N USB Adapter" works!! It is plug and play, no drives to install.
