Wifi Instability
#1
Hi,
I have a new
-Raspberry Pi 3 
-running Openplotter 0.12.0 Alpha
 -dAISY 2+ 
-wireless keyboard & mouse 
-HDMI monitor

Problem: I'm trying to set it up to be a headless system on my sailboat but am still in setup/testing phase at home.  The Pi is connected to my home wifi network successfully.  I'm able to VNC, RDP, and SSH into the pi from my laptop also on the same network.  All runs great right after bootup and as long as I have an active remote connection into the Pi.  If I don't remote into the Pi or if I leave the connection inactive for 10-15 mins, the Pi goes offline.  At this point I can no longer connect remotely into the Pi.  If I use the connected keyboard/mouse/monitor I can use the Pi perfectly fine and see that the Wifi connection to the home network is still up and am still able to connect to the internet.  It's like all the remote hosting services just go to sleep which would make the setup useless in a headless setup.  I have searched this forum and google for other's with similar issues and solutions to no avail.  I have disabled Wifi Power Management and verified it with iwconfig to make sure that wasn't the issue.  

Thank you for the support and such a cool community and technology!

Does this happen working as access point?

When I use it as an access point, it does not timeout/sleep/drop the signal.  So far, it seems quite stable using the internal wifi as an access point.  The instability only seems to occur if the Pi is not setup to be used as an AP and just connected to my home network.  

I do not have a second wifi device to use yet, but my goal is to be able to use the internal wifi in conjunction with an external wifi dongle so that one will broadcast out as an access point and one will connect to my phone to tether internet access.  This way I will have an internet equipped wifi network on the boat.

It does not matter to me, I don't think, which wifi card will be used for the AP and which will be used for connecting to the phone's network.

Is there a way to use the internal wifi to connect to my home network and have a persistent remote access to it?

Thanks in advance : )

I am using the internal wifi for the AP and sharing an internet connection from my house via an external wifi adapter (TP-Link N150 Wireless High Gain USB Adapter (TL-WN722N)). I too have trouble with the uplink to the house dropping after awhile. The AP stays up. LSUSB still sees the problem adapter, iwconfig doesn't, I think ifconfig woke it up one time, another time I had to disconnect the adapter from USB and plug back in to wake it up. I have been blaming hardware/drivers.
