NBN Interference with The TV Reception

We recently got the NBN installed in the lounge room, near the TV, now we are having a lot of interference from it & the TV reception on the LCD keeps breaking up or blacking out, I have tried moving the TV away as far as the cords allow & moving the antenna cord sometimes helps a little but it is still loosing reception, is this normal ? do others have this problem ? How can I fix this ? Please.

    My NBN and router was directly behind the tv unit now as we've moved it slightly it's about half a meter away and neither times did we have any problems.

    NBN - laser light in an optic fibre

    router — wifi operates in the 2.4ghz and 5ghz band, digital TV operates in the 190~536 mhz frequency range, so due to the freq difference a wifi router should not interfere with digital TV.

    It's not your networking equipment at fault.

    Most likely you have damaged cabling (check or replace coax cable and the DTV antenna) or perhaps it's something power-related. Most likely, what might have happened is during the NBN installation, the cable guy must've accidentally cut, damaged or dislodged the tv antenna cable. If you have a rooftop antenna and the cabling is leading from the rooftop and into the walls, you must call an electrictian and have them inspect the cabling.

    • Thanks, it is NBN with wifi,

        Have you turned off the NBN and found the reception go back to normal?

        If this "fixes" issue then there is some electrical interference, if not then like Scrimshaw says then the cable is likely to have been damaged during installation,

        As there is no real power on the fibre to interfere with the TV. Turning off the power (and battery backup needs disconnecting) plus modem power will eliminate these sources for checking.

    Yep get an electrician to inspect your cabling or try a friends external DTV tuner and see if that fixes it. If it doesn't fix it, you have something else going on there. I live in Sydney's eastern suburbs right on the beach and I used to think we had bad reception until I realized that all the low flying aircraft (joy flight/rescue/military/police helicopters and light planes are actually the cause of my problems :/ . Can't fix those myself. Feel sorry for people who own the 10 million dollar houses in my street and can't even watch TV when they want.

      They can probably afford Foxtel and IPTV…why feel sorry for them?

        Because the rich people deserve my pity as well.

        • so….where can I 'share' a rich persons burden???

  • Seems to be the WIFI router, some how, as soon as I turn it off no more trouble - perfect, turn it on & when it restarts the problem is back, tried a different cable but no difference,
    I have moved it away as much as possible from the TV, better but still a little trouble,
    so I'll ring Telstra (oh crap)tomorrow to hopefully replace it (fingers crossed), or get some longer cords,
    Thanks all for the advice.

      There's something wrong with your router. They shouldn't do that.

      Now you are on the way to becoming a technican, first rule is always isolate factors so you can at least narrow down the problem, Getting in expensive electricians etc without at least doing some trouble shooting isnt a bargainers way of operating.

      Given that you have narrowed this down to the router, which I would say to Telstra that you had an electrician come and determine. You are dealing with CSR who will listen if an electrician said its the issue, but if it's you they will assume you know nothing etc.

      They should replace it as it's obviously faulty. But if they require you to do some sort of "test" play along then go back and tell them "nope" it didn't work etc (depending on the "test")

      On the whole Telstra isn't too bad, in the past they were but they have improved markedly

      I would borrow a friends router and test that first. To make sure it isn't something to do with your wiring.

      Wtf it should have absolutely nothing to do with your router. It's on a different frequency it's a wiring / electrical interference issue.

      If Telstra's technician caused that - good luck convincing them.

      Dicksmith might have 5m coaxial cable on their eBay site for 30% off so that could be a temporary fix? Otherwise can you get a new port? Maybe in the same room so they can just run cabling through the roof.

  • I will try ringing tomorrow first, if no good try new coaxial cable at dickies ebay, 30 % off ends tomorrow, try borrow another router,

  • In ballarat newspaper here they said there's been a few thousand complaints in the last few months, being one of the first towns to get NBN they have a lot of bugs to fix so far.

    If your tv cabling from the wall socket to the antenna on the roof is old you probably should replace it with newer shielded cabling. Digital tv seems to be more obviously affected by interference from my observation.

    I had similar issues and a range of things would upset the picture on the tv. Replaced the cabling during a reno and it is all good now.

    Hi All this is a common problem where the NBN have installed WIFI Towers.
    there is a fix and its relatively simple. You need to install or have an installer put a Filter on your antenna. they're easy to fit they have F type connectors on each end of the filter they must be placed between the TV antenna and the Pre Amplifier, not inside the house! they are around $20-40 depending on the size filter you need, it will clean your Picture up completely once you install the filter.
    you can contact me here or your local TV installer should be able to supply you with a filter
    good hunting

    It was our 6-7yo ALDI TV, static leak, used a radio on AM to check, the telsta technician never heard of it so he vidio recorded me moving the radio close to the TV and back, to show the other technicians, so i moved the WIFI 2-3 meters away from TV and now all is good, fixed it.

    • leak from the router, meaning it was faulty?

      • No, The TV was leaking static, badly, it was affecting the WIFI reception, unusual.

        • I thought you said the tv had bad reception not the wifi.

  • Thanks all for your input

    Yes you can be lucky in your case you were In my area we have small towns were the WI FI Towers are swamping the local viewers reception black screens are quite common and you need to resort to external filtering
    I am surprised that by know filtering hasn't been combined with the router
    that would be a simple and cheap solution
