Hello Modem Guru's on OzBargain.

Sorry i have 0 knowledge on modems and NBN stuff ( I'm a old school)

I am currently with myrepublic using their NBN. We have NBN type called HFC.

I am sick and tired of slow evening speed. I am looking to change my modem to netgear nighthawk C1900. Does anyone know this modem will work with HFC?

I am paying $85 for high speed NBN and getting 10MBPS evening time( other times 85MBPS)

Please advise guys. Should I change my modem or change the provider?

Appreciate your help.

    Change the provider will probably help the most. I'm on HFC with Aussie Broadband and get 90-100 MBPS at peak times just using the standard modem they shipped out when I got connected. If your modem is capable of 85 MBPS at non-peak times it doesn't sound like it's the problem.

    Thanks for the reply. One question i always have in my mind, regardless of the providers (myrepublic, aussie, telstra, etc) NBN is the main boss than how come different speeds with different providers even though you paying for the top speed. If you know what i mean.

      I think NBN installs few lines on one street (my street has four nbn lines) and the providers pay NBN to use the line. On my street, Telstra bought two lines for their use only and the other two lines get shared by others. So Telstra NBN is usually faster than other providers since their lines are less congested compare to the other two.

        40Mbps evening speed for the most expensive provider lol

        Not the case. All on one HFC cable.
        If the max he can get is 85Mbps in non peak, it could be cable condition.

        The difference in peak times is the CVC purchased by each provider. The local congestion is still a factor though.

      Depends on how much CVC they purchase to divide up between their users. Some will buy as little as possible, some will buy enough to guarantee that everyone has a good experience (like ABB).

    The modem for a HFC connection is actually the nbn NTD, which takes the coax cable in and provides an ethernet port out. You'll then have a router plugged into this which will give you wifi, additional LAN ports to connect other devices to etc.

    I'm not sure how RSPs authenticate on nbn HFC but you could potentially try plugging a computer directly into the LAN cable coming out of the modem and see if that improves anything - if not, your router likely isn't the issue.

    Unfortunately with HFC on NBN, you cannot replace the modem. Its locked to NBN's system, however you can change providers like Aussie Broadband as suggested which can help with your internet speeds.

    Hello, sure hope someone can help me out here. I'm on Optus NBN, and I'm using the devices that were provided by them. I have wired connection to my PS4. I have wireless connection to all other devices. There are times when my iPhones work, but not my laptop, and vice versa. My PS4 is almost always stable.

    I suspect the modem has issues where WiFi is not stable.

    Should I change the modem? If yes, which is a good choice? I'm in a single storey house, and the modem is centrally located.

      LAN>5Ghz>2.4Ghz

      the problem with 5Ghz is that it does not travel far (but neither does your neighbors to interfere.)

      Check the settings and make sure 5Ghz is on!

      From memory, to use the optus voip you have to use their router.

      There are still a heap of things you can do.

    As knightslay says, Modem (Arris) is property of nbn, and cannot be changed.

    1. Make sure you are using LAN not wifi to check speed. Particularly as overlapping wifi networks are such a problem now for many.
    2. A change of provider may give better results.

    There are 3 factors here.
    1. The HFC line as more users are added (more electrical devices) can perform worse, not able to deliver 100Mbps
    2. The local are congestion (number of people connected to the same cable segment) is high and growing. nbn are spending billions on going to DOCSIS3.1 to combat this. (planned-so does not help now)
    3. RSP CVC They do not buy enough in your area. This is a financial throttle by nbn to reduce the financial losses.

    The first two there is nothing you can do about.

    Your Router can be changed. Connect to 5Ghz where you can. You may be better served by an AP
