Transitioned from VDSL to UFB and installed a Draytek 2862 router 3 days ago 5th March.

There have been a couple of disconnections, and talking to Spark faults just now their RADIUS logs show disconnections on the 7th 4.28am and today 8th March 7.51am.

VLAN tag insertion is set to 10 but on the Service side, perhaps this should be the Customer side? The router does not connect if both are set to zero.

Hoping someone can assist here .. is it perhaps normal to have a UFB disconnect once a day? The disconnection this morning may have lasted for 10 minutes or so ..

Hey Foiler, I would say that's not a normal UFB experiences.

If you're on the chorus network I can check the physical side of the network for you Just PM your address.

Hey, on the physical side it looks fine. There's no errors or drops.

MTU should be set to 1500 Though.

Does that mean the VLAN tag setting is ok? or does that relate to the PPPoE session?

Yup your Vlan tag settings looks good to me 10/0 is correct.

PPPoE MTU should be set to 1500 or Auto for best services.

ok many thanks for the various assistance with this .. resolved that the UFB is in fact stable, except for a couple of managed outages which are now explained as pushing out plan changes.

Throughput question also came up, and that was resolved by changing the defined bandwidth in the Draytek QoS setup .. bit of a trap there where the bandwidth was (for historic reasons) "declared" at 100/20.

The question of MTU came up in the above discussions .. but the Draytek has a tool for determining the highest possible (nearest 8 increment) ..

.. which is 1468.

Does the Draytek support mini jumbo frames?
