Hi @Vickont, You can try reserving the BOSCH's ip address using address reservation in the router's LAN settings.
Log in to the router then navigate to: advanced>network>lan settings, find the alarm panel's ip address in the client's list then add and save that address in the address reservation section below.
Once you've done that then navigate to advanced>nat forwarding>DMZ.
Enter the same reserved ip address into the DMZ host ip address box click enable and save,
Logout and see if that helps the crashing.
I'm just trying to understand what your system is doing, so it has 1 wireless reciever module for communicating to your router with the smartphone app? Can you set a static ip on the system or does it get it's ip from the gateway?
Thanks for the info, I thought it was basically that, I was thinking ip conflict as that's the common denominator with both devices being clients to the same dhcp server. Another thing to try is connect the iphone to the 2.4ghz Wifi band only and then the 5ghz band only to see if there's any change.
The 2.4 and 5g bands use different physical modules with seperate MAC addresses. So it's still doing the same with everything you've tried so far? Have you got an android device you can try the app on?
