hi, i have a 5G outdoor modem NE200, and mesh, 2 be65 (main also), and for outdoor be25 and two x50. here are 5 ppl living so its 5 phones and 5 computers, also have vew other low usage iot devices, 9 cameras and NVR. iot has own network

so i have problem both, ne200 and main BE65, sometimes be65 disconnect from internet, mostly main BE65, red light and no internet, restart only helps even thou NE200 is connected and gives out internet fine, sometimes also NE200 disconnects but it shows sim card error, so im going to change simcard next week so i bet that one is no brainer but still, my main BE65 just shuts it self down, 1-4 times a day, there arent other wifis around, when i activate iot 5ghz, it crashes kinda fast and is not usable anymore untill i disable 5ghz band of iot network, sometimes also is wierd that anytime when apple devices connect, the internet goes away in sometimes after 10-15, sometimes after few hours. another wierd is that when the internet goes away,NE200 shows its connected, also the router itself works because NVR still sees all the cameras, its like somehow the link between be65 and ne200 disconnects,, i previously also had BE65-5G and it did the same thing, just disconnects from internet suddenly, i have done everything to check, different outlets, also dried different unit still, 

previous mesh system, sagemcom f266 didnt do that, worked fine but was slow and low coverage, 1x be65 gets better coverage and higher speeds than 3 of those.

all firmwares the same. BE65(eu) V2
