Hello My parents have an FTTH connection with an Asus DSL-AC68U router which runs linux and pppd version 2.4.7. The network devices are connected to a UPS for stable power. Options configured: lcp-echo-interval 10 lcp-echo-failure 15 lcp-echo-adaptive If there is a short, let's say only 10 minutes, outage between the home and the ISP, the router prints "pppd[17084]: Timeout waiting for PADO packets" messages but it is able to re-establish the connection automatically when the outage is resolved. However if the outage is relatively longer the router just keeps printing "pppd[17084]: Timeout waiting for PADO packets" messages and even if the outage has been resolved the router is not able to re-establish the PPPoE connection. However after a reboot the router is able to establish the PPPoE connection without problem. Because I am remote I am not able to access the router for troubleshooting during outage. Others have the same problem for example with OpenWrt where I also see ppp version 2.4.7 is used https://github.com/openwrt/openwrt/issues/7826 Would you please help what can be the issue and how to fix it? Thank you! Best regards David
