Be92u router

[Gofran]

Hello all hope sombody has an idea i have a modem router. to that is the be92u asus connected and set as acesspoint. how i did is connect wan to modem router. why because i think the be92u has the abillity to go auto lan. when using wan connection

i have few devices example 2 mini pc and 1 gaming pc and 4phones and 3 tablets and a nas.

so this is mine problem.

weirdly only mine pc the gaming pc gets disconnected randomly as in can take a day or few days.

things i have tried

1.reinstalling windows.

2.disabbled everything like energy saving setinngs in windows.

3. checked everything latest update and even whent back bios and router patch updates.

4. as in lan connection and wifi connection. the issue happens.

5. i replaced the cables as in lan

what i find strange is that al other devices work fine.

il add a picture i see two times 1 wan/lan see picture does that mean that be92u did not change to lan maybe and need to put modem cable to number two port see picture.and why only mine pc or was this just bound to happen and mine system is the unlucky one everytime.

Is the WiFi of the modem/router disabled?  So all devices connect directly to the RT-BE92U?

Please verify the firmware version installed on the BE92U?

Hey so this is situation how iam running it.

Operation Mode:Access Point(AP) mode Firmware Version:3.0.0.6.102_38962

and its modem router wifi is on yes and no some are connected to the wifi be92 and others are on the modem router because they are closer to that.

but 

i already tried reseting both device's.

but the devices that are connected to be92u never disconnect the only thing is mine pc gaming rog xii formula.

as in wifi and bot lan connection have the issue by disconnecting and then after like 30 second or a minute come back online.

The disconnect is after Windows falls asleep?  Unfortunately I experience that.  Windows 11 24H2 and also Windows 11 25H2.  It's a lot quicker than 30 seconds.

Can you connect the PC to the modem/router and it doesn't disconnect?

[Gofran]

no i have that all of no sleep no save energy also the monitor

[Gofran]

at the moment i am trying that until now no disconnect but i need to test more because with the other it can take a day or two untill hapens again.

Not sure if I'll be able to sort out Windows side, but is this the correct motherboard?

Do you suspect the RT-BE92U is causing the problem?  Or the PC?  Or both?

[Gofran]

yes correct motherboard i wondering if there is a security setting that is was on i dont know about. because at accespoint. i left it standard

maybe this picture is also interesting.

Memory use above 90% can affect performance.  USB HDD can cause high memory use if connected to the USB port on the BE92U.  I am not aware that it would affect Ethernet but there is also USB 3.0 noise to WiFi...
