Based on what you say, Rogers is providing IPv6, but the router is not passing it. Rogers uses something called DHCPv6-PD, which not only provides an IPv6 address for the router, but also the prefix for your LAN. So, either your router doesn't support DHCPv6-PD or it's misconfigured. The fe80 link local addresses are essential for IPv6 to work properly, but will not work beyond the local LAN. For example, with IPv6, your gateway address will likely be a link local address, even though it may have a public address. On this computer, my default gateway address on IPv6 is fe::1:1, even though it also has an address that begins with 2607.
When your router is working properly with DHCPv6-PD, it will announce the LAN prefixes to all devices on the LAN. The devices will then take that prefix and create a host address, using either the MAC address or a random number.

The Mississauga server is no longer in operation. That was the one closest to me.
@TomasLee don't know why you indicate that Passthrough mode should be the operating mode for Asus routers. That reference to Asuswrt Version 3.0.0.3.78 is for a version that is 6 years old. Asus has long since moved on from that version and has rewritten its firmware, so I would completely discount the reference to using Passthrough mode. Checking latest versions, for example:
RT-AC68U Version 3.0.0.4.385.20433 Released April 14 2020
RT-AC86U Version 3.0.0.4.384.81792 Released April 14 2020
Check the latest version released for your router model.
Native IPV6 is what Rogers has developed and this is used across multiple routers and multiple operating systems.
At the present time I have one of my routers running Merlin's Asuswrt, running Native IPV6 without any problems, as have others.
To run IPV6 on an Asus router you have to set up IPV6 as follows:
Connection Typs: Native
DHCP-PD: Enable
Release prefix on exit: Enable
Auto Configuration Setting: Stateless or Stateful (Stateful works now. It didn't for a very long time)
Connect to DNS Server Automatically: Enabled or Disabled as per your preference
If you disable that setting, you will see the three IPV6 DNS server address entry windows. Enter the addresses as required.
Enable Router Advertisement: Enabled or Disabled as per your preference.
Apply the setting and reboot the router. When all is said and done you should end up with the router running Native IPV6.
"Release prefix on exit"
Are you sure you want to do that? If you do that, your prefix can change, which means all your addresses will be different and it makes it impossible to use a DNS server to point to your devices. There is a similar setting with pfSense and I set it to not release.
I can be convinced to use either setting. I think that might be the default for Merlin's Asuswrt, but, don't quote me on that one.
If all you're doing is going out to the Internet, it makes no difference. However, if you want to access things on your network by host name, then you'll want addresses that stay put. The same is true if you want to access your network from elsewhere, such as with a VPN, etc.. If your address can change, you'll find yourself locked out. I found out about this when I discovered that simply disconnecting/reconnecting the Ethernet cable to the modem was enough to cause my prefix to change.
@Longpar3 running stock firmware or Merlin's Asuswrt? Your settings look correct, but, typically you have to reboot the router after setting it up for IPV6.
Reboot both modem and router. Pull the power for the modem, wait for about 15 seconds and plug it back in. While the modem is rebooting, reboot the router. The end result should be IPV4 and IPV6 to and through the router when the modem and router reboot cycles are complete.
The modem is running in Bridge mode, correct?
@Longpar3 my first question at this point is how are you running a Surboard SB-6141 modem? Rogers usually doesn't allow private modems to run on the network. Did a Rogers agent at a Rogers store or did someone at tech support manage to register that modem on your account? Just wondering at this point how you even got to this point with that particular modem?
The internet plan cost comes with a built in modem cost for what ever modems are eligible for your particular internet plan. The installation tech should have installed an appropriate modem or Rogers should have sent you a modem via courier. Thats the modem that you should be using.
"I guess I will have to figure how to log in to it to see if it's in bridge mode."
What WAN address do you get? If in one of the RFC1918 blocks, the modem is in gateway mode. If a public address, it's in bridge mode.
Rogers can provide a /56, which means you get up to 256 /64s. A /60 will only get 16.
@clarenceb5 there appears to be 4 versions of that particular router. The latest version, V4 is listed on the datasheet as running 680 Mb/s for NAT throughput. That is IPV4 Network Address Translation throughput. So, if you're getting 400 to 450 Mb/s throughput, that implies that you have an earlier version, or, that the router, even if it is a version 4 router, is maxed out.
Here's the support page for the router.
https://www.tp-link.com/ca/support/download/tl-r600vpn/
You have to select the correct version to download the datasheet that matches your router. On the bottom or back of the router, should be a product sticker which indicates the version of the router.
It appears that you need to buy a faster router to run gigabit rates. Practically speaking you can expect 940ish Mb/s on the downstream side, considering the ethernet overhead.
If you're looking specifically for faster VPN rates, you need a router that supports Intel's Advanced Encryption Standard New Instructions (AES-NI). At the most these days with OpenVPN, you could see somewhere in the order of 250 Mb/s with an Asus router running Merlin's Asuswrt. OpenVPN is a single threaded application, so it will max out one core of a multi-core processor. Processor speed and AES-NI hardware support is the key to running faster VPNs. Alternatively you could run Wireguard on a pc which is a multi-threaded application, and which should produce faster VPN data rates.
Just as a test, you should kick the modem into Gateway mode, connect your pc to the modem and run a speedtest using the www.speedtest.net Rogers Toronto, Montreal, or Ottawa server, which ever is closer to your home. With the www.speedtest page up, change the test server and type in Rogers to display the Rogers servers. You could also use the Rogers speedtest which is located at:
https://www.rogers.com/customer/support/article/internet-speedtest
The question at this point is, are you actually seeing ~940 Mb/s on the download side and 30 Mb/s on the upload side?
