    Pair this with the Telstra $15 5 gig data plan that shapes your connection to 1.5mbp once you surpass 5gig.

    • using those cheap usb dongle works the same for me

    • It wasn't so long ago that the max speed you could get on Telstra ADSL was 1.5Mbps!

  • I cannot find any firmware updates on their website. Can anyone help me figuring out when the firmware was last updated before clicking the buy button?

    • Just asking why the need to update the firmware straight away

        Think they’re trying to establish currency and general support.

  • Cat 4? Why use this over say the nighthawk m1 which can be had around the same price?

    I used this for a year before getting nbn and can honestly say it is fantastic. Really reliable and easy to setup. D/l speeds bw 15-20mps on average and up to 45 on a good day. The m1 gets horrible reviews on Telstra.

  • So does it know that your network is down and then connect to 4G?

    • Yes.

      We use them at work as failovers for our remote sites; been flawless.

      • How did you get that to work?

        Had this for a while as a failover for the home FTTP nbn. The thing would randomly switch to failover and then shortly go back to the NBN. when it goes back to the main line, it never actually connects back to the main line. I would have to power cycle the device to get it to work on the main line again.

        searched the internet for a solution, but the forums indicated that it is firmware issue and Netgear has never addressed it.

        But as a 4G modem, it works well. Just the failover function seems to be really buggy.

          It's just plug and play for us.

          No special config.

          We have them in over 50 sites, on the same SDWAN

          • @MasterScythe: Hmmm… no issues reconnecting to the main line after the drop? Are they running the latest firmware?

            • +3

              @CheapNGood: I believe you guys are talking about different use case scenarios.

              Masterscythe may have a dual wan router behind this modem and configured this 4G connection as failover, thus the router will decide when to switch over. In this case, Netgear WAN is empty, LAN is connected to one of Router's WAN port.

              However CheapNGood's setup is more simple as using this modem both as a router and 4G modem. Netgear WAN connects to FTTP NTD and LAN connects AP/Switch. Under this config, the Netgear modem will decide when to switch to failover 4G and so causes issue.

    Is this better than the Huawei B525 4g modem ? I'm running a B525 is it worth the upgrade ?

    • If am not wrong b525 is cat 6 I say stick to ur b525
