Re: New Optus-supplied NBN AC Routers

Hey @Jiefu, the modem doesn't have an external antenna. It's the same size as the N version of the Sagemcom F@st 3864 but it's black instead of white.

 

Yes, you'd need to take up one of our in-market plans when recontracting, there's no way around that unfortunately. If we were replacing your existing modem under warranty you'd receive an N version original Sagemcom modem as a replacement. I hope this helps.

Re: New Optus-supplied NBN AC Routers

@Hannah-L Thank you for the information and the photograph. I have also received Specifications from another moderator Jax, who has been really great and I will post them up here for others to see. It does seem odd though, the specs indicate 2xUSB 2 ports and in your picture I can see a USB 3 port on the RHS of the photo.

Anyhow, I want to upgrade my hardware, but not my plan, what do I need to do?

 

Thanks, Jeff

Re: New Optus-supplied NBN AC Routers

The other USB port is on the back of the modem. 🙂 If you'd like to go ahead with the upgrade please let Jax know via private message and she will place an order for you.

Re: New Optus-supplied NBN AC Routers

which is the better modem. I see one is offered on one plan and the other comes with a dearer plan

Re: New Optus-supplied NBN AC Routers

@Khun_Tilt

The specs are for the 3864AC modem which is a wireless AC device; it is backwards-compatible with wireless N and wireless G (by default).

 

@dottway

The Sagemcom 3864 has a white enclosure and is wireless N: the Sagemcom 3864AC has a black enclosure and is wireless AC. The AC version is, therfore, 'better'. My best guess is that they are otherwise similar.

Re: New Optus-supplied NBN AC Routers

Hey Guys, I had the White N series router and I bought the Black AC router without changing my plan. Admittedly it cost me $99 to do this, but the choices are limited if you want a home phone as well.  I was going to follow a path of my own, but since getting the 3864 AC, I have found little that does not meet my requirements so far.  I am on a FTTP connection and I have tried it a full speed for a month as well. It handled that and I was hitting D/L speeds of 95 to 98Mbps. Now I am back on my normal tier and I am 47 to 51 Mbps with the wifi throughput in house to laptop at 867Mbps on the 5Ghz and anything on the 2Ghz always at 300Mbps.  The 3864 N never achieved better than 270 Mbps and the D/L speed was always giving me grief at 30 to 45 Mbps, with many drop outs occurring each week.

The 3864 also has other features which are useful when turned on, such as beamforming technology, IPV6 is there if OPTUS enable it and it has the two bands, 2.4 and 5 Ghz.  I have about 12 wireless items connected with only about three of them on the 2.4 ghz frequency and the rest on the 5ghz frequency. I also have one hard wired computer which is connected at 1Gbit via cat 6 ethernet cable. The home phone has been fully functional except for two occaisions, but then it is a Telstra Cordless 🙂 so it's probably feeling like it is on strange turf.  If you want to have the phone and not mess about, dual band capability then the AC version is a good choice.

Re: New Optus-supplied NBN AC Routers

@Newline  I'm not sure what the point of your comment was. Bricko made the comment the new modem was NOT AC but N. I just pointed out it was both. Whether N is there as part of backward compatability or not is irrelevant.
