I have been on TPG NBN HFC for about 2 months and observered stange traffic on disconnected LAN ports. I was monotoring traffic as I had seen reports of bad performance of NBN and HFC but I must admit having a stable and good speed with Speedtest.
TP-LINK AU brushed it off since the frimware is a TPG version. TPG support told me to reset the router but I refused as there is no backup/restore option and I have 8 devices with fixed IPs and other tweaks so I rebooted the device at 9:00 11/10/2019 with wifi disabled and only one LAN port connected to another access point - to cut down on number of variables.
Attached are 2 screenshots about 5 dours apart 4 days after the reboot.
The access point is on LAN 4 and compare it to the ewan_pppoe data.
Has anyone seen similar behaviour?
Traffic monitor stopped logging traffic last night so I have reset the counters again. In the system log there were ppp3 errors (see attached) that I had not seen before. Previous logs just had VOIP, DHCP and DSL retraining entries.
Seems someting went down around 4 am.
The disconnection lasted 3 minutes from 04:40 to 04:43 and it seemed to stop the traffic monitor logging any traffic - it flat lined at zero rx and zero tx. Using the web interface I reset the traffic data and the logging traffic resumed.
I assume something happened on the HFC connection - the first I have encountered.
