@BenoitVIALE, there are three ways to do what you want to do.
- The first is to convince the owner/operator of the Central Router to disable IPV6. It is possible to live without it, however, there are good reasons to run IPV6 for some XBox games to avoid NAT issues.
I'm not exactly sure at this point if you are referring to the modem, or follow-on router when you refer to the "Central Router".
- Failing the attempt to run the Central Router in IPV4 mode only, you can run a secondary router as an ethernet and wifi access point off of the Central Router. In your particular case, that secondary router could be set for IPV4 mode only. If you had a printer connected to the Central Router, you would have access to that printer through the secondary router.
- If you are referring to a modem - router combination as the Central Router, then the modem should be running in Bridge mode with the router in full router mode. You can run a secondary router as an access point off of the existing router, as indicated above. You can also simply plug in a secondary router into the modem and set that router to operate in full router mode. The modem will supply a second IPV4 and IPV6 address to that added router and you can simply disable IPV4 in the router for your purposes. In this particular configuration, there is two independent networks running, so, sharing files and printers across the networks would not be possible.
In terms of wifi it gets a little interesting. You should have a look at your wifi settings and the existing wifi environment to see what channels are occupied and which might be unoccupied. I would expect all 2.4 Ghz channels to be occupied. The 5 Ghz channels may or may not be totally occupied. Your preference should be to use the upper channels, 149 to 161 as the power output from a device is allowed to run at 1 watt max. The lower channels are restricted to 50 or 200 mw, depending on when the device was approved by Industry Canada. 200 mw is the newer limit.
check/set the following 2.4 Ghz wifi parameters:
Wireless Mode: 802.11 n
Channel Bandwidth: 20/40 Mhz, although, for test puposes you could set this to 20 Mhz. In a crowded wifi environment, I would set this for 20 Mhz.
Wireless channel: AUTO or, to an open channel if one existed, or to the channel that offers the least interference from neighboring routers and modems
WPS Enabled: OFF
Security Mode: WPA-Personal
Auth Mode: WPA2-PSK
Encrypt Mode: AES only
TKIP is no longer secure and will cause the wifi data rates to cap at 54 Mb/s which is the g rate.
Check/set the following 5 Ghz wifi parameters:
Wireless Mode: 802.11 a/n/ac mixed
Channel Bandwidth: 80 Mhz, although, for test puposes you could set this to 40 Mhz
Wireless channel: 149 to 161
WPS Enabled: OFF
Security Mode: WPA-Personal
Auth Mode: WPA2-PSK
Encrypt Mode: AES only
Look at your wifi environment using one of the following applications:

In the modem itself, if you have a white CODA-4582, there is a wifi Site Survey under ADMIN .... DIAGNOSTICS. Since it uses all three of the 2.4 Ghz antenna and all four of the 5 Ghz antenna, its fairly sensitive compared to a laptop or phone. The user interface isn't great, but, you can copy all of the data in one go and dump it into something like MS Excel, where you can sort it any way you want.
That;s the last freebie version of inSSIDer and at this point in time is getting a little old. Its fine for 2.4 Ghz application and does work for 802.11n 5 Ghz networks. It does display 802.11ac networks but not as well as it should. This has become a licenced application now for $20 US and works very well for both frequency bands, 2.4 and 5 Ghz.
The other applications are fine for 802.11ac. Acrylic is graphical, WifiInfoView is text only.
The actual settings wouldn't be a problem. I can send you a list to follow which details all of the settings. The 1900P would be a good choice. There are other forum members who have bought that router and as far as I know to date, they are satisfied with the 1900P's performance.
When you indicated the "Central Router", does that indicate the Rogers modem, or does it indicate a router that is already connected to the modem?
Depending on what is already installed the end result might look like one of the following:
1. Modem - 1900P The 1900P operates in full router mode
2. Modem - Existing Router - 1900P The 1900P connects to one of the Existing
Router ports and is set to run in Access
Point mode
2. Modem Port 1 - Existing Router This router operates in full router mode
Port 2 - 1900P The 1900P operates in full router mode
Normally the router is connected via Ethernet cable to the modem. You would then connect to the router via ethernet or wifi.
The router has three operating modes;
1. Router mode: The router provides Firewall, IP addresses, wifi services, etc, etc.
This is connected as follows: Modem - ethernet cable - 1900P - ethernet cable or wifi - XBox and/or other devices using IPV4 only.
2. Access Point mode: The router is used as an ethernet and wifi Access Point, but, it relies on the upstream modem or router for firewall and IP Addresses.
This is connected as follows: Modem - ethernet cable - 1900P - ethernet cable or wifi - XBox and/or other devices using IPV4 only.
3. Bridge mode: This is not the same as the modem's Bridge mode. In this mode, the router connects to the modem via wifi and relies on the modem for firewall and IP addresses. You would then connect to the router via ethernet connection. What I don't know at this point is whether IPV6 is enabled when you enable this mode. I suspect that its not as IPV6 on the router is enabled via a second tab. All of the devices connected to the router via ethernet should be running IPV4 only. If you used wifi from the modem as the connection, that would still be running IPV6, but, the IPV6 addressing should stop at the router and not go beyond it. So, this brings up the question of what you really want, an ethernet connection that provides IPV4 only, or both ethernet and wifi that runs IPV4 only. It also depends to some degree on where the modem is located and where the router will be located.
This is connected as follows: Modem - wifi connection - 1900P - ethernet cable only - XBox and/or other devices using IPV4 only
At the same time, for your wifi devices, you would connect as follows:
Modem - wifi connection - other devices using IPV4 and IPV6
If you intend to connect to the modem via wifi, then you have to consider the network that is currently operating and you would want to ensure that the modem's wifi network is set to run as efficiently as possible and that the router is connecting at the highest possible data rate. That would probably mean that your first choice would be a 5 Ghz wifi connection, but, that depends on the existing wifi environment, so, you would have to look at that and see what the best operating channel might be. That could be a 2.4 or 5 Ghz channel but I would bet that the 5 Ghz channel would be the best choice.
Hey @GoodData,
I can totally appreciate wanting to be in the know when it comes to your modem's settings and security capabilities! I'll be happy to provide what information I can and perhaps some members of our community may also be able to share their insights as well.
Regarding advantages of having IPv6 enabled, there's a few general notable ones such as increased packet processing and routing efficiency as well as support for new services. By eliminating NAT there's also a true end to end connectivity at the IP layer so not just P2P connections but VOIP and QoS are improved as well. All of this essentially just means a more fluid/consistent browsing and device utilization experience.
As for the setting "ICMPv6 Inbound to Hosts", this covers a necessary selection of ICMPv6 requests. As ICMPv6 handles a variety of necessary features for IPv6 functionality leaving this enabled is recommended. Regarding your security query, IPv6 does have several security improvements over IPv4 so having both enabled would be optimal. I will note however that while it is common practice for the firewall to disable IPv4 echo requests to protect against things like denial of service attacks, port scanning via IPv6 is not nearly as common and ICMPv6 is necessary for IPv6 to function. Filtering specific ICMPv6 traffic would not be available through our current modems.
I hope this helps in answering your questions!

Hi @GoodData,
I'll be sure to forward your feedback to RogersAndy 🙂.
To my personal knowledge there's no common reason a residential consumer would need to filter any of the ICMPv6 requests as doing so would likely cause visible usability issues, such as websites taking longer to load or not loading at all. Filtering can be a complex task that does involve a wide depth of understanding in both what your security requirements are and how best to filter unidentified packets without impacting the user experience.
That said, ICMPv6 packet filtering can be done in an effort to gain protection from denial of service, probing or redirection attacks among others but these are not common over ICMPv6 and know that our network is scanned continuously to track any traffic that may be conceived as malicious. These kind of filters are typically set in place via firewalls for businesses.
