Hi All,

I have an issue that has bothered me for a year or so now and I have a workaround but not a solution.

I have Spark FibreMax (PPPoE VLAN 10) that is being run by a MikroTik RB2011. Approx. every 3 months the unit will get stuck in a PPPoE loop which in the logs goes "Initializing" -> "Connecting" -> "Terminating" -> "Disconnected"

The work around is to unplug the ONT from the wall for 15-30 mins then plug it back. Quite annoying.

I found an article here which looked to be someone with the same problem but nobody really had a solution just a hypophysis in why it was happing.

Hope you can help.

Cheers.

Hi put in a netwatch entry to ping say 8.8.8.8 every 1min and timeout of 2.5sec, the script below assumes your pppoe session is ref 0

/interface pppoe-client disable 0; delay 10; /interface pppoe-client enable 0; :log info "pppoe restarted"

disable detect wan.

you will likely find that for whatever reason it's sending a dhcp packet.. it's a nasty little quirk of mikrotiks

Interesting! I actually turned this on via the app thinking I was doing myself a favour. Will let you know how I get on.

Cheers.

Yup that's a fun feature of that app... it expects you to use the feature... but doesn't warn you of the downsides.

to be fair, on many networks you won't notice a thing.

on some providers you won't notice this as they are less attentive to invalid traffic...

Mikrotiks are a funny beast with quirks like this
