Hi

There are around 25 devices in my home connected to this router via wi-fi (there are no devices connected to  LAN ) .  Router was configured in standard way . I only changed DHCP service  with range 192.168.1.10-199.

I reboot this router everyday at 10:00pm. In most days everything is ok , but somtimes (once a week)  , after reboot, only around  15 devices are connected , rest devices are not connected. When i see this strange case , I reboot router manually (from web page or by unpluging and plugging power supply cable) and in most cases  it helps , but ....somtimes i have to reboot router many times. 

When i see this strange case , log file shows me after reboot  :

Recv REQUEST from xx:xx:xx:xx:xx:xx

Send ACK to 192.168.1.18 

....

for this 15 connected devices

.....

then i see  log entry :

LTE connected UP

then i see next log entries for the rest of NOT connected devices :

joining wifi xx:xx:xx:xx:xx:xx

leaving wifi

......

Could  someone  help me ? to solve this strange router behaviour ?

as you can see , after "LTE connected UP" someting is wrong with wifi..... strange :)

thx a lot !
