Bridge Mode Setup Guide

Hey fellow forum users.  If anyone is willing to help me with this, it would be appreciated. 

I am wanting to make a 'bridged mode setup guide', pretty much one thread, which goes

"smc - how to"
"Cisco - how to"
"hitron - how to"

 

And would also put in a 4th section, of the alternative of how to set up your own router as just an access point as well.

As i have general knoledge, i havent done the setup myself on all the models, i am asking for your help/input.  Pretty much just step by step instructions, login, this page, change this, reboot... as detailed as possible.

 

This way we have an easy spot for reference for users comming in to point to - will be requesting it to be stickied at the top of the forum.

 

---

Yes i understand that this shouldnt be necessary, etc.. they should offer d3 modems, etc.  I dont want to get into that in this thread 🙂  Its more to collectively get this together to be able to help other users with setting it up.

Please feel free to reply here, or PM me with the info.

I look forward to your input.

Ok, here is a simple check you can do.  Look at the back of the CNG3ACR, specifically the connected port LED.  If the LED is amber, that means that the CGN3ACR interconnect rate to the airport extreme is 1 Gb/s, which will support all of rogers high speed data plans.   If the LED is green, the data rate between the two devices is capped at 100 Mb/s.  Can you let me know what colour it indicates.

 

Also, please check the model type at the back of the modem while you are there.  Is it a CGN3 or CGN3ACR - CGNM.  Silly question possibly, but I know that Rogers is short of the CGN3ACRs and as a result, customers have been receiving CGN3s.  If that is what you have, the CGN3, with the previous version firmware throttles down a 100 Mb/s connection, or connected device to 35 Mb/s max.  If this is the case right now, this will be corrected in approx three to four days when the next version firmware is uploaded.

 

The remaining question which ties in with the LED colour and modem type is what is the WAN port speed of the airport extreme.  Is it 1 Gb/s or 100 Mb/s.  I don't know the answer to that one just yet.



Re: Bridge Mode Setup Guide

Then beyond that.. would be looking at your wireless setup.

Depending on the limiations of the airport extreme wireless and your devices... interfearance, etc.. which can limit the speed.

Those speed tests i am assuming were on WIRELESS and not WIRED?

The LED is green.  It's a CNGM modem. 

 

My speed test was wireless both before and after the change.  Before the change of modem I got faster speeds than with the new, same setup.

Ok, that indicates that the max data rate to the airport extreme is currently 100 Mb/s.  That is either due to the airport extreme WAN port speed, or due to the connecting cable.  The CGNM will not be able to determine which of the two is the limiting device.  What model year is the airport exterme, and do you have another Cat 5e or Cat 6 ethernet cable on hand that you can swap in for a test. 

 

The only way to really determine if you are seeing the data rates that your plan calls for is to run a two step test. 

 

1.  The first thing to try, in your current configuration with the airport extreme in place is to connect a pc or laptop via ethernet to one of the LAN ports on the airport extreme.  Run a speedtest using Rogers speedcheck or the speedtest.net Toronto Telus server.  Take note of the ping time, download and upload rates. 

 

2.  The second step is to reset the CGNM back to Gateway mode by using the reset button at the back of the modem for 30 seconds and releasing it.  While it is rebooting, disconnect the pc or laptop from the airport extreme and connect it to one of the CGNM ports.  Can  you have a look at the connected port LED and let us know what colour it is.?  You could disconnect the airport extreme at this point or turn it off, just for test purposes.  When the pc or laptop has picked up an IP address from the CGNM, run another set of speedtests using the same servers. 

 

What you should see, on both wired tests are peak download rates above 100 Mb/s when you factor in the additional rate provided by Rogers speedboost. The upload rates should also be up just over 10 Mb/s as well. 

 

The whole purpose of doing this is to determine what the wired data rates are, through the CGNM and through the airport extreme.  If they are where they are supposed to be, in both cases, then the issue is solely between the airport extreme and the wireless devices.  If they turn out to be less than expected, that leads to the following questions:

 

1.  Is there a cable signal problem?  This can be determined by loging into the modem (at this point its using the default cusadmin / password combination), navigating to the STATUS.....DOCSIS WAN page, copying the downstream and upstream tables and pasting them into this thread.  With those tables, its possible to determine if there are any problems with the cable feed to the modem. 

2.  Is there an ethernet cable problem?  In that case, do you have a spare Cat 5e or Cat 6 cable around that you know is in good condition that can be swapped in for testing, so that you can rerun the tests.

3.  Is the end test device capable of supporting 100 Mb/s?  That sounds like a silly question but to accurately gauge the capability of the delivery system, you need a pc or laptop capable of download rates much higher than 100 Mb/s.  We have an Acer laptop that simply will not run above 200ish Mb/s, wired or wireless, so it's pretty useless when it comes to testing our 250 Mb/s connection, which provides for peak download rates as high as 340 Mb/s. 

 

When we have the wired rates nailed down, we can then look at the wireless situation, knowing that the data rates through the CGNM and / or airport extreme are where they are supposed to be.

Wow..thank you for all that.  I did try a cable swap using the short ethernet cable that came with the modem which I presume would be up to spec. 

 

I will have to get ahold of a laptop from work that I can run the wired test with.  My laptop here is a macbook air with no ethernet port. 

 

The airport extreme I believe is the 2011 model.  There is a wiki page for airport extremes.  Will follow up asap!

If you wanted to connect the Macbook Air via ethernet, you could probably use a gigabit USB 3.0 ethernet adapter.  We have a couple of these around the house for occasions when I want to run the Acer on a wired connection:

Of course drivers are always a question.  Here's the support page for the drivers:

Not sure if that would work with the Macbook Air or not.

 

On a windows laptop it actually works pretty well, but as I indicated, the Acer won't go beyond 200ish Mb/s, which isn't bad for a small laptop.

Or a Thunderbolt Gigabit Ethernet adapter, assuming it's a new enough MacBook Air that it has Thunderbolt (but if it isn't - it won't have USB 3.0 either).

Re: Help making a "Bridged Mode Setup Guide"

Out of curiosity, what protocol is used between the router's WAN port and the CGN3?  Does the router send a DHCPRequest?  I presume it needs to get a public IP, DNS server address(es) etc. from the head end.

Re: Help making a "Bridged Mode Setup Guide"

Have a look at the following Wikipedia page.  Hopefully that will answer your query:

I'm Here A Lot

Gdkitty, I found your thread and I am looking for help. I have just obtained a new Hitron modem/router from Rogers. I would like to continue to use my Apple Time Capsule as my wireless router. Can you tell me how to go about setting this up? Currently, I am using the Rogers modem as my wireless router but I would like to switch to using my TC instead.

Re: Bridge Mode Setup Guide

its the CGN3ACSMR?

Not 100% sure if its the same as the regular CGN3.  Hopefully someone else can confirm.

Log into the modem. (cusadmin/password  or whatever you changed the password to if you have)

 

Go to the BASIC tab.
Here you will have to wait like 5+ mins, till it loads the FULL client table below, before you can move tabs 😞
Once the table has loaded, go into the GATEWAY sub tab.
In there, should be the option to turn off the commercial gateway functions.

It will then reboot the modem, and then be in MODEM mode. 
Make sure at this time you are DISCONECTED from the modem, as it will latch onto the first device into it.. which should then be your ROUTER you are using in bridge mode.

Re: Bridge Mode Setup Guide

 

@Gdkitty -  I can confirm it's similar to CGN3, below is the screenshot from CGN3ACSMR model.

Cheers,

RogersMoin

 

P.S: To my understanding with CGN3ACSMR model, when you go to the Basic Tab, the connected devices will not load automatically anymore unless you click on the "Show" button. I believe this was the improvement over CGN3 model, so you don't have to wait until all connected devices are listed to move to another tab.

 

Perhaps @Datalink can confirm if this is true.

I Plan to Stick Around

Just an observation about Bridge mode on the CGN3.    As Rogers have seen fit to turn off the IPV6 configuration pages** on the Hitron, those few of us who use Rogers 6RD service have to use bridge mode to use it.  I have not found a router than can access the 6RD stuff via the CGN3 in Gateway mode.

 

** According to the Hitron web site the CGN3 can do all the IPV6 modes, native, tunneled  and 6RD.

Re: Bridge Mode Setup Guide

I Plan to Stick Around

I am on CGN3ACSMR modem. I presume bridging instructions are the same for the ones described here. I have a question before I decide to go ahead and bridge it. In my network setup I have assigned DHCP Reservation for local IP for multiple devices and NAS, so they do not change and I am wondering will it change once I bridge my Rogers modem/router? My understanding is that once I attach new router to replace gateway of Rogers modem it will be automatically assigned IP 192.168.0.1? Am I correct? From there I would be able ro re-assign permanent locla IPs for my devices?

 

Thanks for help!

 

 

Re: Bridge Mode Setup Guide

Good Afternoon @bbajovic,

 

Thanks for reaching out to us!

 

Perhaps one of our resident experts @Gdkitty or @Datalink can confirm this for you.

 

Regards,

@RogersGabrielle

Re: Bridge Mode Setup Guide

Possibly.

When you put it in bridge mode, all that happens is that the rogers modem will assign the EXTERNAL IP address to whatever device/router you plug into.

When you plug it into  your 3rd party routers  WAN port, it will then assign your external IP address to the WAN side of your router.

From there, its whatever settings your your router has.  IF its setup for 192.168.0.1 as your internal, your good to go.

hello all, i have some question about bridge mode Hitron GCN2 I've set it to bridge mode about 2 years ago, and I really cannot remember if I turned off wifi or not before i change it. Since then I've been away from home for a year and recently got home and noticed the wifi light is blinking, should I be worried? I was under the assumption bridge mode disable all routing function and wifi function, or could wifi still be working under bridge mode?

Re: Bridge Mode Setup Guide

I wonder if the modem has seen a power failure or someone has reset it, and as a result it has come back up in Gateway mode instead of Bridge mode?  That might explain why the wifi might be up and running.  You should check the modem and see if you can log into it.  In Bridge mode that shouldn't be possible.  In Gateway mode it would be possible.  You would have to connect to it directly via ethernet or wifi.  The default wifi parameters can be found at the back of the modem.  If the wifi is up and running on its default parameters you would be able to detect the network with your laptop and log into the modem by going to 192.168.0.1 and using cusadmin and password as the login credentials.  If the login page comes up, but you can't access the modem, run a factory reset by depressing the recessed reset button at the back of the modem for thirty seconds and then releasing it.  After the reboot, log into the modem and change the modem's passwork immediately to prevent anyone from accessing it via wifi.  To return the modem to Bridge mode, navigate to STATUS..... CAPABILITY page and disable the Residential Gateway Function.  Hit Apply and reboot the modem using the Reboot function located in the WAN/LAN Backup page.

 

If you load inSSIDer onto a laptop, you will be able to see if the modem wifi might be up and running.  It would be the highest powered network on the display.  If you unplugged the modem, you would see the network slowly drop in power level on the display and then disappear.  That would confirm that yes indeed, it was up and running.  Here's a link to the last freebie version of inSSIDer.  There is a new pay version out now that can display the 802.11ac networks in the 5 Ghz band.  If you use 5 Ghz networks, for $20, its worth having it around.

Re: Bridge Mode Setup Guide

thanks for the suggestion, but I think it is still in bridge mode because in my own router's WAN port the ip is Rogers assigned IP instead of the usual 192.168.x.x ones.  Also when I run trace route to external site the hop after my router's IP is already Roger's network IP.  Things seem to indicate it's in bridge mode...

 

I did download some signal strength testing app on my phone and place it on the modem, no ssid seems to suddenly increase in strength so at least there's that. 

Re: Bridge Mode Setup Guide

Its still a bit strange that you would see the wifi LED lit.  Thats the first complaint of its type for the CGN2 that I've seen on the forum, but, I haven't done a search for any others.  It wouldn't take much to run a reset and then kick it back into Bridge mode if and when you have time on your hands and nothing else to do but experiment with it 🙂

I Plan to Stick Around

I exchanged my modem with the CODA but when in bridge mode my router cannot get an IP from Roger's DHCP server thus no internet connection. My router was working fine with the previous modem in bridge mode.

There are few of us who have this issue and no one can help us. My router is TP-Link Archer AC2600.

I did all the suggestions in another topic but still the same.

 

Anyone can help?

 

Thanks
