R7000 keeps losing IPv6 WAN address
Hello, I'm with Rogers Cable and am able to obtain and keep an IPv6 address when using the Rogers Hitron CGN3 gateway, but when I use the R7000 it gets an IPv6 address for an hour or so and then ...
ElaineM - It seems this entire situation has to do with the Hitron CGN3ACR modem. Apparently all the Hitron CGN3 AC related modems including the 3552 have this exact issue when in bridge mode. In gateway mode they can hold an IPv6 address, but in bridge mode they seem to have an issue passing the address to a third party router.
I changed the modem to a Hitron CODA-4582, bridged it, and I've had an IPv6 address on my Netgear R7000 since doing the change (over two days now).
ElaineM - No firmware version has been able to maintain an IPv6 address for more than an hour or so.
I've been trying IPv6 for the past year or so. Everytime a new fw version is released, I update it and try IPv6 again. I'm currently on the latest version V1.0.8.34_1.2.15.
Noted on that. I thought you had it working previously with a lower fw version.
Let me check on this and will get back at you.ElaineM - It seems this entire situation has to do with the Hitron CGN3ACR modem.
