NBN drops the second it rains (then fixes itself shortly after)

    I must confess i started my career working in ISP support, but im perplexed as to why this is happening.

    I have Internode NBN.
    FTTC

    Since getting it installed (I didnt immediately draw the correlation) as soon as I hear it rain hard, the internet stops working. it'll be gone for about 3-7 minutes. And then it will continue working (with no degraded speed from what I can notice).

    Why would this be?
    It might make sense that it drops when it rains and doesnt come back. But the fact it comes back is unusal?

    Appreciate my next steps in terms of troubleshooting. Trying to avoid any "NFF Tech Callout Fees"

    Wait just your net goes down or the physical device goes down?

    You would think so - but then why would it start working a few minutes later presumably while still raining hard? Usually water logged damage waits for the rain to die down or stop and for a little bit of time for it to dry out. The fact it goes out then comes back 5 minutes later doesn't fully preclude this but it does make it a bit peculiar.

    A guess would be that it takes a few minutes to fail over to a backup system - the fault may be further upstream.

    I have a similar problem but I'm on HFC, whenever we have decent rain we lose connection. A few hours after the rain stops it comes back. If it is prolonged drizzling rain it's fine, it is only just the big downpours where it goes out.

    what changes with the LEDs on the NBN NCD when the issue occurs? specifically the DSL and link LEDs? (latter looks like two chainlinks.)

    this is very peculiar as there would be a piece of equipment getting very wet that shouldn't... if you can log the faults and downtime..maybe ask your neighbours if it happens to them.. all of you get on your respective RSP's to escalate it then it "might" get fixed

    Had the same thing in Mosman with HFC. Heavy rain and the net would go down for a day or so. Once it dried up the service would restore.

    A search for "NBN rain" produces many many results... gotta love relying on old copper!
    Old building, old wiring?

    Some may disagree, but I highly doubt every pit has been "repaired" by NBN too.

    If it's not sorted eventually then;

    To be fair to the copper...

    My folks place in inner Brisbane - Red Hill, the copper there is what was put in, in the 70's, the ol PMG days, it's been as reliable as anything - far better than my place in a 17yo estate. I guess if you dont put joins in at every pit - and only when you need to, its fantastic.
