    Please don't buy this. It's CAT4 rated which is probably about 10+yrs old. Will be slow as crap and I don't think it supports carrier aggregation.

    Best to buy one of the Huawei CPE modem routers that are standard issue for Optus customers if you're on a budget. If you can splurge then one of the Netgear Nighthawk modems would be better e.g. M1, M2, M5

      They're fine, I'm using three at different remote sites and they can maintain 100mbit down. Don't need 1 billion gigabits/microsecond for a backup/failover connection.

      OP - check ebay, people get rid of them fairly regularly

        Yeah no idea what the guy is on about. Stats show average 4G speed in Australia is <50Mbps anyway. My company have deployed dozens of these to plenty of sites across Vic and they run entire companies perfectly fine off them.

        Negs aren't for use because you don't like facts people.

            @dasher86: That's not the same at all though. That's nothing more than a glorified WiFi hotspot with no LAN out or WAN passthrough.

            @dasher86: I think thats a totally different use-case. People consider this Netgear unit because it has dual Ethernet with failover abilities albeit no wifi. Yes, it is a CAT4, not saying its not old tech, but definitely not logical to compare the 2.

          @Tacoo
          How well do they work when connected to a primary gateway, on the gateway's secondary WAN port?
          E.g. Can they function as a bridge for the router to the mobile network?

          • Tacooo on 13/08/2021 - 15:20
            +2

            @thedriver: They work perfectly as a bridge. That's exactly the use case in 90% of the scenarios I've used them at work. Clients either run Unifi, Sophos or Cisco gear and we use this as a failover WAN.

            • bdl on 14/08/2021 - 08:18

              @Tacooo: I second this, this is exactly my use case (i run pfsense in front of them)

              Despite being Netgear, they have been rock solid.

    • geek001 on 13/08/2021 - 13:04

      I am using a Huawei modem from Optus on Vodafone. Just be aware that the bands are not the same, so the Optus Huawei modem cannot do CA on Vodafone. If I use my old 4 year old Samsung phone to usb tethering, I can get average 150mbps on Vodafone, but on the Huawei modem, I can only get around 70mbps. Still better than wired NBN though, I can only get around 22mbps.

      • futaris on 13/08/2021 - 13:13

        Try huaCtrl

        • geek001 on 13/08/2021 - 13:37

          I have the huawei e5186 modem. I tried doing something similar using the e5186 toolbox, but I think the CA band combinations required a special huawei code. I couldn't find the code combo for CA bands for Vodafone, which was either B1+B3 or B3+B5, I can't remember. I gave up after a while, chalking down to the bands not being supported.

          70mbps is adequate, I don't think I felt any difference between the 70mbps and 150mbps. Our 500GB data allocation gets chewed up pretty quickly anyway with the higher bandwidth, because all the video streams on devices connected to the modem started to stream in full HD, because they could.

          • ESEMCE on 13/08/2021 - 13:49

            @geek001: E5186 you;'re correct will only do CA on Band 40 which is specific to Optus.
            It's a Hardware rather than Software limitation I believe.

    Would this be any better ? Says it’s cat 6 (which means nothing to me !) but it’s around your price range.

    • beaker on 13/08/2021 - 12:13

      I would go with this one as the antenna's are replaceable, which means you could point something at the tower from outside. I was looking at this option before we had the NBN connected last year as we don't have the best mobile reception in the house

      • iJebus on 13/08/2021 - 12:27

        You can plug external antennas into the Netgear. Oops I read that the wrong way around.

      Thanks for the link; yeah I spent a little time looking at the GL.iNet devices but ideally I want to get something that does one thing only and does it well. I read in the comments somewhere that they don't do passthrough and I don't want another router, another wifi device etc in the mix. Yeah, can turn things off but still. /shrug

  • Rimus on 13/08/2021 - 12:47

    Anyone could share their experience on a good not so expensive router to be used with Optus Huawei E3372? I tried TP Link TL-MR3020, which didn't recognised the E3372. Is their better GL.iNet ones? Tks in advance.

    • lwinstan on 13/08/2021 - 13:18

      I did EXACTLY the same thing earlier in the year. You probably have the Huawei e3372h-608 which isn't supported by the TP Link TL-MR3020. It only supports the Huawei e3372h-607.

      As such, I eventually ended up with the TP-link m7450 (CAT6), which has been great in my house with a strong LTE signal, not so great in my other house with a not so great LTE signal.

      I will be looking into these for the not so great LTE house:

      • Rimus on 13/08/2021 - 21:18

        Tsk for feedback. I was looking at B818, but nothing less than $100 I found. Currently using an old Ac68 with E3372 but feel wasted resources. Need for a granny flat, no need for greater wifi coverage.

    Teltonika or GTFO. Remote management, complete pass through, ideal for business usage.

    Telstra Smart Modems are $30 on Gumtree.
    Whack in a SIM Card (if the existing one doesn't still work) and you'll get as fast or faster speeds.

      • ESEMCE on 13/08/2021 - 14:47

        They're $30 cause Telstra post them out for free as a ploy to keep you on network during transition to NBN.

        Even before hacking (Technicolor variant only) to unlock them, they're perfectly acceptable modems, and an absolute bargain for a very capable 4G modem, especially if Telstra is your only choice of vendor anyway.

          i never got more than 2 bars signal on mine while my phone always had 5 (both telstra) and the wireless range in a tiny 2bdr house couldnt get wifi down the hall.

          put my somewhat old R7000 on instead and had wifi half way down the street.

            @Laserface: The indicated signal strength is irrelevant if you're still pulling 100mbps+ on 4G in your chosen location.

            And the WiFi signal strength on a Smart Modem is better than the complete lack of WiFi capability in the OP's modem which is after all what we're comparing to here.
            If you need better WiFi, you've got $110 leftover in the budget to spend before you break even with this "deal".
            You can easily grab a Ubiquiti AP for that sort of money which will blow most devices out of the water in WiFi range and performance.

              -1

              @ESEMCE: the telstra technicolors offer it as a backup to your primary connection and from what i could tell it was speed capped anyway. I never needed it but there was zero incentive to keep the telstra router at all given the wifi was also rubbish.

              The netgear product is not speed capped, actually works and gets decent signal, and isnt a huge white ugly box that even gumtree orcs dont want.

              • ESEMCE on 13/08/2021 - 20:02
                +1

                @Laserface: The 4G backup SIM is indeed speed capped to 25/2, but that is a SIM restriction not a modem capability limitation, unlike the Cat 4 modem in the Netgear.
                Stick in a proper SIM and the Smart Modem itself is speed uncapped with Cat 6 Carrier Aggregation capability that will allow it to double the Netgear in 4G throughput.

                This Netgear device does not have WiFi at all, so the WiFi capacity of the Smart Modem is infinitely better out of the box or it's irrelevant to the discussion. You consider it relevant enough to list it as a negative, so therefore it's another massive win to the Smart Modem.

                Appearance, wow, you're really clutching at straws now!
                Bland white box versus bog standard black modem with green flashy lights…
                (I disagree that the Netgear is better looking at all, but even if you consider it so) Is it really $110 better looking especially given it's otherwise inferior?

  • mcnugged on 13/08/2021 - 14:21

    Would the speeds from these modems be faster than going through a phone?

    As in would the antennas on these be better able to pick up weak signals?

    • ryang on 13/08/2021 - 14:32

      Generally, no. A mobile has a better designed antenna.

      Some can take external antennas though, which gives you a heap of options.

      • Laserface on 13/08/2021 - 14:40

        we use these for remote offices. they have MIMO antenna inputs and you can connect them to the repeater devices that telstra use, if necessary.

  • opt on 13/08/2021 - 14:34

    While this is not a fast modem by today's standards due to only supporting CAT4 / no carrier aggregation etc.. I think lot of people are missing why OP is considering this modem. They are looking for a 4G failover modem for a regional area, this one has external broadband passthrough with automatic failover and external antenna support, not all 4/5G modems have those features.

    A quick google search for B818 brings up few 3rd party sites advertising 4G failover mode as a feature, but I suggest OP read up more and make sure before buying a B818 or any of the other suggested modems if the primary purpose is to have an automatic 4G backup. But if someone is just looking for a fast 4G modem then, steer clear. There are far better options out there as indicated.

    P.S: I've had this exact same modem a few years ago, from what I recall I got around 25~50Mbps. But since then I've used a B525 and now using a Nighthawk M5. Both a lot faster than the LB2120. M5 can hit speeds over 500Mbps on 5G.

    • CheapNGood on 13/08/2021 - 18:11

      I have a LB2120 which I bought a few years ago (2nd hand thank god), not sure if it is the same as the LB2120 LTE, but for the pass through and failover it has bugs in the firmware which apparently was ignored by Netgear. For me it would randomly cutover to mobile even though the house FTTP was fine, but then would not cutback to the main line until I restarted it. Not sure if the firmware is fixed as I gave up waiting for a firmware update and shelved the device. I did in the end use it as just a normal modem behind a load balancer which handled the failover and passthrough

  • arctan on 13/08/2021 - 18:53

    Anyone had experience on this 4G LTE modem? I think it has all the bands for Optus and Vodafone.
