Regarding the 2.4GHZ band on the new CGN3ACR, the bandwidth setting defaults to 20MHZ out of the box as well as on a factory reset. Tech support can change the setting to 20/40 (above or below) on the Wireless Advanced Tab (only tech support can see this tab)... doesn't seem to help... have not been able to achieve a 40MHZ bandwidth connection on any WIFI device standalone i.e. excellent RSSI and nothing else connected. In my case, the CGN3 performed better on the 2.4GHZ band... at least 20/40 was the default and 40 worked some of the time. I would stick with the CGN3 for 2.4GHZ, jmho.
The CGN3ACR is the CGNM as per the label on the back of the device. Seems like the intent was to provide better performance on the 5GHZ band.
Lets see if anyone else has the same feedback.
Just swapped the CGN3ACR back to a CGN3 ... speed back to normal at 70 to 80+ mbps on 2.4GHZ with an n300 connected at 144.5 mpbs (20 MHZ bandwidth), right out of the box, no changes to settings...
I barely got more than 40 mpbs out of the CGN3ACR on the 2.4GHZ band, same n300 device, same connection speed of 144.5... sometimes only 4 bars out of 5 on the connection, whereas the CGN3 always had and still reads 5 bars consistently
sad but true
By the way, if anyone has a large house and wants to set up a prosumer Wifi network to leverage off of your Rogers internet service I would highly recommend the Ubiquity Unifi line of WAPs. These cost about $100 each and look rather like smoke detectors and are meant to be ceiling mounted. They are powered by PoE and they come with PoE injectors if you don't have that in a switch.
They come with good software that allows you to manage your network, see who is connected, set up Guest accounts, etc.
I've tested some UBNT gear like the ERL and the UAP-AC. I also opened up the gear I was testing and was dismayed by the quality of the internal components used. The ERL performed to my satisfaction during the test period but the internals shocked me so I would not trust the gear. The UAP=AC performance was mediocre at best for an AC device. I for one cannot recommend UBNT based on the poor quality of the internals and the dismal performance of the UAP-AC -- the only positive that I can offer for the UAP-AC is the controller software --- it works well and does a very good job managing multiple UBNT AP's.
Apologies if this has been covered already, but I did not see it elsewhere...
I recently got the new "Rocket wifi modem" (CGN3ACR) and I notice there are 2 USB ports at the back. Can I use one of these for an external HDD whose contents would then be available on our home network? We have 2 desktops (ethernet connected to the modem/router), and various wireless devices (tablets, etc.)
Last year I bought a 3TB WD external drive, which is connected to one of the desktops - I know, should have got a proper NAS device.
My perhaps naive thought now is that, by connecting it to the CGN3ACR USB port, I could access it across the network... voila, it becomes a (sort of) NAS??
Eh.. yes, kind of.
many of these devices.. they are natoriously not always that easy to connect to.
I know via PC, you should be able to connect/map a drive to it, via an SMB share..... but other devices, maybe not so much? (tablets/phones dont always have the same connectvitity options as a PC, etc).
NAS or NAS like networkable hard drives, often will set up standard windows shares where you can easily browse to them, and will have other sharing options like DLNA, etc for other devices as well.
(or, leaving them connected to a PC which does the same... but requires the PC being on.)
I am currently using the CGN3 and it is NOT compatible with my current voip.
Hitron CGN3 (Rogers Advanced WiFi Modem)
Current Status: Not Compatible
Recommendation: Replace Device or Bridge it to a compatible router.
The router feature of this device lacks the ability to disable SIP ALG and is not compatible with VoIP. We recommend that it be replaced with a standalone modem and router that is compatible, or that it be bridged to a router is compatible. We DO NOT recommend placing a phone on the DMZ of this decvice as it would compromise the security of the phone.
Is the new CGN3ACR more programable for voip systems? Does it have controls for SIP and ALG?

The CGN3ACR is the exact same firmware, etc as the CGN3.. so it would act exactly the same.
Its really the NAT which is effecting these things.
SOME people have had luck (it may vary from VIOP to VIOP provider), with using port forwarding and being able to use the device fine.
All in all.. the recomendation there of using bridge mode, with your own 3rd party router is BEST solution.
From the VOIP then likely working without issue..
And then that just general routing/switching will likely be much faster, as well as better wireless performance.
You need to call tech support and have them disable the SIP ALG setting. Its one of those settings that are accessible to the user on third party routers.
First and foremost the CGN3ACR has been accessed by using 192.168.100.1 when the modem is operating in Bridge mode. So, it is possible in that case to access the DOCSIS WAN signal level and signal to noise ratio data, which is useful for troubleshooting problems. The CGN3 no longer has that capability as of the firmware update issued in Dec 2014. Hopefully it will return in a future firmware version.
This is not my experience with the CGN3ACR.
I have been with Rogers for a very long time and have always been able to reach 192.168.100.1 utilizing a variety of Cable Modems or cable Gateways in bridge mode [within my networked environment] but not so with the Hitron CGN3ACR or the CGN3
I know that 192.168.100.1 does work if I connect a 2nd PC to a secondary switch port on the CGN3ACR bridged .
To make sure its not my Firewall [ZyXEL ZyWALL USG100] and it's latest firmware --- I tested against a CISCO DPC3825 in bridge mode and had no problem accessing 192.168.100.1 --- it is my opinion that Hitron have not fixed the 192,168.100.1 access issue in either models.
