Spark Fibre on white Smart Modem 1 has been working well for a couple of months up to 800MBits down and almost the same up with 3ms ping.
In the past week, disconnects have started to occur. No pattern.  They kind of come in swarms.  Nothing for 12 hours then a couple disconnects.  Then an hour. Then a couple.  Basically green light goes red on modem and although it was coming back routinely quickly it seems to be having harder time now.  Spark run line check and are sending out swap out modem to test.  I have isolated the modem from all other devices just connected directly to ONT and the same issue.  Log extract from modem below - any thoughts or advise appreciated as I'm meant to be streaming tournament games and this is not ideal:

What do the lights on the ONT do during this? It's looking like the ethernet link to the ONT is dropping out. Try another cable.

Had tried 2 different ethernet cables already and removed the modem completely from the rest of LAN to exclude conflicts.


Just looked at ONT during an outage and the GPON has gone out (not lit) and LOS is solid RED and LAN 1 is still flashing green.

That sounds a lot like a fibre fault. Surely they can see that the ONT is dropping off the network?

The DB loss must be right on the limit for the ONT, get Spark to raise a fault with the LFC and mention your findings. Will need a tech to come out and possibly test with an OTDR and replace patch leads, resplice or re blow.

It would appear it was the Spark Smart Modem.

 

Swapped out with the test unit and have not had a single drop in over 24 hours.

Doesn't explain GPON LOS at all.




Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

Tend to agree although my knowledge on such matters is limited at best.  If I didn't have the pics of the lights on ONT I would be doubting my own recollection.  That said tech is weird and Spark was correct to swap modem as the first step evidently.
