Can't log in to CGN3

I Plan to Stick Around

We recently upgraded to the Hybrid Fibre 150 internet package, and got the new CGN3. 

What I want to do is change the name of the network from "OnyxMagnolia", and, change the default password of the network, also if there is a way, get rid of the "Guest" network and the "5G" network? Not even sure what the 5G is.

But I can't seem to log in. Called Rogers support on the first day and they told me to hook up ethernet cord to the modem, which I did, and log in using the username "cusadmin" and password "password", same as it says on this page, which I did. It keeps telling me "Login Failed. Wrong Password"

What is it that I am doing wrong here?

Looks like.. you might have got a unit, which was NOT reset, before being given to you.

Best bet, would be to do a FACTORY RESTORE on it.

 

fine the little pin hole in the back of it, and press something into it.. hold it in for a good 20 odd seconds.

It will reboot, and then should be back at factory settings.

you then should be able to plug in wired, and log in via CUSADMIN and PASSWORD

 

Once in there, under the wireless settings, you should be able to change all your wireless names, password and settings.

 

The 5g listed.. there are TWO wireless frequencies that wireless normally runs on 2.4 and 5ghz.

Most common is the 2.4... which tends to have a slightly farther range as the 5ghz... BUT.. there are a TON of stuff like portable phones, bluetooth, microwaves, etc.. which all run on the 2.4ghz freqencies and can cause interfearance.
Its an alternate wireless network, you can connect to with a device which supports 5ghz.

If that is the name of the networks that you see on your laptop, it looks like that is a recycled modem.  On that presumption, depress the recessed Factory Reset button on the back of the modem for 10 seconds and then release it.  That will initiate a factory reset and reboot.  After the reboot, you should be able to log in with the "cusadmin / password" combination.  The 5g network is the 5 Ghz network, one of two that the CGN3 will broadcast, the other of course is the usual 2.4 Ghz network.  Did you happen to use the setup key at all?  Hopefully not, as the results cause more problems than that key is worth.  The key is used to setup a guest account, set up parental controls and name the wired network.  But, as I have indicated, don't use it.  Log in manually at 192.168.0.1 to access the user controls.  If after the reboot you detect a Guest account still broadcasting from the modem, call tech support to turn it off and have them also turn off the Home Monitoring SSID, in case its on and broadcasting.  Home monitoring has its own modem now, but used to run off of the internet modem.  If you need to monitor the modem after its up and running you can load inSSIDer onto a laptop and check out the networks that it is broadcasting as well as any other networks that might be running nearby.  It worth knowing that as it will explain any interference problems that you might encounter from other networks.  Here's the link:

We have 3 people in this household actively using the internet right now. I brought it up with them and told them I'd be doing a factory reset on the modem and the internet might be out for a little while. Can you guarentee me that this reset thing won't do any damage and make me need to call in again?

Also, there are two frequencies, yes? We have two laptop computers, one smart TV, one Playstation 4, and three smart phones. Should I be connecting different devices to different frequencies? If so, which ones to which?

I apologize for my lack of knowledge here.

Re: Can't log in to CGN3

Damage? no.

It will require them to have to re-connect into whatever the NEW wireless name(s) are... but beyond that should do absoluetely nothing else.

There are many on here who have done the factory reset MULTIPLE times.

 

As for WHICH to connect to?

IF someone has a device which can SEE the 5ghz one.. and its showing a GOOD singal for it?
Personally, i would say to try it.. you might get less interfearance possibly from other things.

Otherwise, 2.4 should be fine..

(one thing, when setting it up.. and setting up the NAMES.. make sure to name the 2.4 and the 5 ghz networks DIFFERENT names... dends to play nicer with some devices.)

Re: Can't log in to CGN3

Well, look at it this way. Without the factory reset, you won’t be able to access the modem to make the changes you need to make. Normally it’s a trouble-free procedure. If you do run into problems, take the modem back and exchange it. Just let the reset run on its own and it will take three or four minutes to complete. When its done you will see the two wifi lights at the bottom of the front row of LEDs lit.

 

Frequencies, yes the CGN3 runs two networks, a 2.4 and 5 Ghz network. Note that the CGN3 wifi certificate does not indicate concurrent operation of both networks, which is rather interesting. Its listed as 2.4 GHz, 5 GHz – Switchable. I run the 5 Ghz network only from the CGN3 without any problems. Depending on the layout of your home, your device capabilities and potential interference from neighbouring wifi routers, you need to decide whether you want to run on the 2.4 Ghz or 5 Ghz band for your devices. The 2.4 Ghz networks have a better range but may run at a reduced data rate compared to a 5 Ghz network. Due to the design of the 2.4 Ghz channel spacing, overlapping 20 Mhz channels can be seen from the bottom channel to the top, so that presents challenges when it comes to finding a clear channel to operate on. The 5 Ghz channels are 40 Mhz wide and do not overlap. And, given the fact that the vast majority of devices run on 2.4 Ghz, the 5 Ghz channels are usually wide open for use, unless of course you live in an apartment. My usual advice is to kick as many devices as you can up to the 5 Ghz band. Some may only run on 2.4, so there won’t be any choice there.   Those that run on a 5 Ghz band you should experiment with, as the trade off is potentially a slightly shorter operating range from the modem versus higher bandwidth, which gives you a higher data rate. Keep in mind the certification which doesn’t indicate concurrent operation, although I’m sure that many people run both networks at the same time. Only caveat is to name the networks with different names, so that the devices can display both networks and allow you to choose the network that you want to use. There are problems with networks that have the same name, where the device isn’t able to select the desired network on its own. So, keeping the names different makes that process fairly foolproof, or should I say device proof.

 

One of the best ways to determine what channel to use is to load inSSIDer on a dual band laptop, as I mentioned above. That program will show you both 2.4 and 5 Ghz networks graphically, making it fairly easy to understand how many routers are nearby that could cause problems for you. You should see a marked difference between the number of 2.4 Ghz networks and the 5 Ghz networks that are nearby.

 

A couple points to keep in mind, combo modem / routers don’t have the greatest wifi performance. A good third party router with external antenna will give you better wifi performance and better control over features that you might need such as port forwarding. If you are going to use the 5 Ghz network, set the channel to 149 or higher as the output power for those channels is higher which should give you better range.

OK - Success! I was able to log in and rename both frequencies and change the password for both the internet connection and the CGN3ROG login. Tested out the new connection on all devices.. Noticed that the 5G network is not showing up at the moment at all. Not a big deal at the moment I guess. The guest network IS still there. Is having that network there a problem? I notice that if we do try and connect to that, it brings you to the Hitron login and asks for a password. Which is good I suppose.

Thank you very much for all the help.

Re: Can't log in to CGN3

5g wont show up on your device, unless you have a 5g capable card in it (not all do)

 

Your not the first to mention with the stock now.. seems to have the GUEST network..

I dont think there is a way to change it from OUR login into the router.. you might have to call into rogers, see if they can remove it for you.

Re: Can't log in to CGN3

The only way to turn off the guest network is to use the USB setup key, which I strongly advise against (throw it out) or by calling tech support to have them turn it off.  While you are there, ask the CSR to also ensure that the Home Monitoring SSID on the CGN3 is also turned off.  When that is done, you should be able to look at the CGN3 network with inSSIDer, and only see two networks running, one 2.4 Ghz and one 5 Ghz, provided you have a dual band laptop.  Even with a single band 2.4 Ghz laptop running inSSIDer, you should only see one network broadcasting from the CGN3.  If you look at the MAC address of the networks on the network list, you should not see another MAC address that is almost identical to your network's.  The only difference would be the last right hand digit.  Those columns on the inSSIDer network display can be sorted up and down by selecting the top column title so that would make it easy to spot another network broadcasting from your CGN3. 

 

If either one of the networks is being broadcast you will see a corresponding LED at the bottom of the front LED display.  So by looking and observing that both 2.4 and 5 Ghz LEDs are lit, and not seeing the 5 Ghz network on your laptop, that would pretty well confirm that the laptop is not 5 Ghz capable.  If you drilled down to the Control Panel .....Device Manager and copied the adapter model and pasted it here, we can look up the specs to confirm it. 

 

Given the fact that this looks to be a recycled CGN3 that had been used with the USB setup key, if you have any problems with it, don't hesitate to take it back in and exchange it

When putting it in bridge mode can I do it my self or do I need to call in? Can anybody here help me on doing it me self. And one other thing can I use my own router as a wifi extender without bridging rogers modem and being able to still use there ethernet ports is there a way?

Re: Can't log in to CGN3

You can switch the CGN3 to bridge mode yourself.  Here's a link to the instructions:

 

http://www.rogers.com/web/support/Internet/home-networking/247

 

And, you should be able to use your router in bridge mode so that you can park it somewhere else in the house and connect via ethernet to the router.  Newer routers typically have a choice of operating modes, including, router and bridge modes.  If your router has it built in, it would just bea a check box in the settings.

 

Food for thought, if your house has strutured wiring which is a bundle comprising two RG-6 cables for satellite or cable tv, one Cat-5e ethernet for data and one Cat-3 (possibly Cat-5e) for telephone, you can run data all over the house by completing the Cat-5e cabling.  That is another way around the problem of accessing the internet throughout the house.

What I was asking can I use my third party router without bridging rogers gatway / modem ?

Re: Can't log in to CGN3

Yes you can.  That is the way i have MY setup.

CGN3, NOT BRIGED.. with all four ports in use.
2 going out to two seperate wired switches.. 1 out to the Rogers Home Security router.. and one out to my ASUS RT-N66U as an access point.

The ASUS does my WIRELESS.. but the CGN3 does all the routing, forwarding, etc.

 

As to HOW to set this up.. it will vary from 3rd party router to the next... some have an AP mode.. some are just turning off settings, etc.

Re: Can't log in to CGN3

Given the fact that your running three Xbox’s you might be better off running the CGN3 in Bridge mode and use the Nighthawk for your router, unless of course you have the three Xbox’s already up and running without any issues. I still believe that using the Nighthawk as the main router would be a better solution as you would hopefully get rid of latency issues with the CGN3 when it’s running in Bridge mode. That might be worthy of an experiment just to be able to compare the two configurations and see which one is better for gaming.

 

To set up the two devices with the CGN3 in Gateway mode, you would turn off both wifi networks on the CGN3. For the Nighthawk, you would turn off the DHCP server so that the CGN3 handles all of the LAN IP addressing, and assign an IP address to the Nighthawk that is outside of the range of the CNG3’s LAN IP address range. That will require you to take the Nighthawk IP address out of Auto Mode and manually assign an IP address.  Once done, that will enable you to log into the Nighthawk to make configuration changes in the future. That should do it I believe. Plug the Nighthawk into the CGN3 and reboot the Nighthawk. You should be able to log into both in the event that any changes are required.

Just bridged the cgn3 and using my own router called netgear night hawk ac1900 , did some speed test and I was surprised that the CGN3 gave me better speeds and was more steady on wifi and direct connect all firmware up todate so what can be the cause of this Realy thought a 3rd party router would give me better speeds the the rogers CGN3

I'm trying to connect my CGN3 to my VOIP Obi110. I had some success with my previous Rogers modem router but I was told to "upgrade " to the CGN3. I have not managed to get anywhere with this modem! I thought and tried bridging the CGN3 with a cheaper D-Link N300 but all I managed to do is slow down my internet by half. Later I lost all use of Internet when trying to revert back. The frustration continues. Any help would be appreciated.

Well, your older dlink, might be SLOWER than the CGN3 in wired and wireless means.. so that could have done that.

(especially if your CGN3 hasnt updated to the new 4.2.4.5 firmware.. the router would have hit the 10/100 bug with the previous firmware)

All in all, i would at min, start be reverting your CGN3 to FACTORY.

There should be a little pin hole in the back.. depress it for a good 20 seconds, let it fully reboot.

That should set it back to gateway mode, factory settings.

 

 

From there.. can move on to your other issues.

As for your VIOP..  the CGN3 NAT is pretty strict.. and seems to not directly play nice with most VOIP units straight out.
USUALLY they will work fine, as long as you set up the port forwarding rules specific to that device.
(you would have to find out what they are).

Alternatively.. IF you get a newer/more up to date router.. you can bridge it properly (and get full speed), which many play nicer with the CGN3

I tried logging in using cusadmin/password. Didn't work. I'm trying to port forward for a Minecraft server. I have the Advanced Modem/Router. Please help!

Re: Can't log in to CGN3

Is this a modem that you have just installed or have you been using it for a while?  Either way, if you can't access the modem, the quickest and only method to guarantee access is to run a Factory reset.  Depress the recessed reset button at the back of the modem for 10 seconds and release.  The modem will run a factory reset and reboot.  When that is done you will see the two wifi LEDs at the bottom of the front LED display go active, indicating that the 2.4 and 5 Ghz wifi networks are active with default settings.  Open a web browser and enter 192.18.0.1 as the address, which will take you to the login page.  cusadmin / password should work to gain entry to the modem. 

 

1  First thing to do is change the modem password located in the Admin...Management Screen

2. Second thing to do is turn off both wifi networks as they are using the default network names and passphrases, or, change them so that they don't use the default names and passphrases.

3.  complete the other settings as required

4.  Create a backup file and store it on your pc so that if you ever have to factory reset the modem, you can simply restore the settings and be back in business within a couple of minutes of starting the reset.  Go to the Admin.....Backup tab and create a backup file.  If you ever need it, following a reset, return to that page and run the restore.
