@Andrask  I am assuming the VPN you mention is being accessed by a VPN app on the mobile device. If that is the case, a poor Wi-Fi signal, among other network issues can cause this. One example might be poor roaming. If the transfer from one AP to the next is not fast enough, and your device hangs on to the weak signal of the current AP, that can result in the VPN tunnel closing. Since you mentioned " able to move within the house without disconnection" specifically, I have a suspicion that could be your problem.

If you are running the VPN app on the mobile device, you could look into running VPN on your router itself so the VPN connection is not dependent on your Wi-Fi. For example on my router, I have a VPN set up that I connect to when needed.

@Virgo ,  @RickJamesBish thanks for your comments!

Let me add a bit more context.

Two scenarios:

1)I work remotely and I need to connect to the corporate VPN on my laptop. It works seemlessly without any disconnects if I stay stationary. If I switch floors it disconnects and I need to connect again

2) similarly, I run a test here using my phone: packetlosstest . com. Started the test, packages were sent and received. As soon as I moved between floors and it switched to the other AP, it carried on sending packages but stopped receiving back any. If I restart the test on the floor all works fine.

Therefore I feel that maybe something is wrong with my setup/router settings/DHCP/ or general the mix of vendors that I have in place now?

  @KimcheeGUN this tool is fantastic, thank you!

I did a survey across the whole house, and also performed a test specific to the VPN connection.

I was connected to the purple natras (3rd below), then walked to the basement, it switched to blue (1st below) around -65.
In the moment it switched to the new AP, the VPN got disconnected (23:15:06).

From the below screenshots, do you see anything 'obvious' that I am doing wrong?

 


 

  @Andrask Not sure if this has been asked or mentioned but are all of your APs wired back to a switch or router, or are they MESHED?  Since you have not mentioned a controller I assume they are all wired.

If they are wired and not meshed, I would test again and get an RSSI between your device and basement AP, right at the location where it switches over. In the graph you provided, it appears you have some very weak signals.
