I'm having issues with a new Synology RT2600ac on Spark (fibre connection). When the router is turned on (it gets turned off overnight, nothing I can do about that), it fails to establish a PPPoE connection. It won't try again unless the connect button in the Web UI is pressed or the WAN cable unplugged and plugged back in again, in which case the connection establishes. Any ideas on what's causing it or how to get the router to retry the connection again after it fails the first time? Router is on the latest firmware.

I thought Spark was DHCP, is it not?

Also, enabled VLAN ID 10 in the IPTV section?

Is the ONT turned off as well? Possibly the ONT is taking longer to boot than the router?

Nope, Spark is PPPoE.

Yes, VLAN is set correctly. It works if the WAN cable is unplugged and plugged back in again (also, if the connect button is pressed in the Web GUI, in Network Centre).

Unfortunately that's out of my control.

No, ONT stays on. Also, if I turn it on, wait for it to boot (after which the PPPoE will be disconnected after a connection failure) then wait 15 minutes then try to connect in the Web UI the connection fails.

still does not explain why the router is getting turned off when the ONT is still on? what are the reasons for turning the router off? how is it out of your control? the router should be left on at all times unless there is a power cut in my opinion.

the only pppoe issues that i know of on some routers is exactly what your describing so the end result to fix that is not to turn the router off and put it on a UPS

The OP has already said that this power cycling is out of their control - there's probably a social reason for it, such as a flatmate with a tinfoil hat, but if there's nothing the OP can do about it, then it would be helpful to solve the technical problem that results.

Ok, I have a RT2600ac but on a 2degrees connection so won't have any other suggestion...

Now in really interested to know if it is a tinfoil hat situation!

A mikrotik with out wifi would solve this problem providing its left on all the time it will keep the PPPoe session live then all you need to do is setup port 2 for DHCP and let the synology connect to that to give you wifi

Does the Synology router not have a wireless schedule, could this not help with someones tin foil hat?

Turns out Synology recently released an update (1.2.1) that isn't available through the router interface yet but is available from their site that among other things:

Fixed an issue where PPPoE might not be able to re-establish the connection once it has disconnected.

Now it fails on the first PPPoE connection attempt (like before), but now retries and succeeds on the third or fourth attempt (so after about 4 minutes 30 seconds from the router being turned on at the wall). So not sure if it's the router or something at Spark's end. So it works now, but the added delay is annoying some (for a comparison I tried our old router, an old Netgear, which boots in 1 minute 30 seconds and gets a PPPoE connection immediately).

What happens when you reboot your router? Mine takes about 2 minutes to boot, then tries its first PPPoE connection attempt (I can tell by the ONT lights). A second one comes a bit later and a third around the 4:30 mark, which succeeds (this is on 1.2.1). If it's a router bug, it may exhibit itself on yours as well, unless it's something specific with my config (but I haven't changed much) or its something ISP specific triggering it (I presume you don't reboot your router all that often, so probably wouldn't have noticed the issue if it exists?).
