For about three months and 3-4 Asuswrt-Merlin versions I have a Problem. I switch off router and modem overnight via a timer. This worked until 3 months without Problems. Since that time, both devices start but the Internet connection does not work anymore. I have to restart the Asus router again (during ongoing modem) thus the Internet works. It appears that the router starts faster and the modem is not ready. The router will then appear in a "no Internet" loop to hang instead of recognizing that the modem is also started and reconect. Is there a Firmware fix?
