Hello,
Could you please confirm from which firmware version the devices were updated to 7.14.2? Also, was the update performed with ‘Keep Settings’ selected or not?
For testing purposes, please try executing the following commands via CLI/SSH on one of the affected routers:
uci set network.mob1s1a1.dhcp='0'
uci commit network
/etc/init.d/network restart
Additionally, check this similar topic here: RUT956 disconnecting every hour with ESM reject
Once applied, kindly monitor if this brings any improvement. If the issue persists, we’ll need to continue the investigation and troubleshooting privately.
Let me know the outcome.
Best regards,
