super this ip is modem native with a ethernet cable to my gentoo box, my tp-link have now badly config that make ipv6 not working, i was have problem with incomming ipv5 via the tp-link, but outgoing ipv6 was ok on all lan ipv6, will try to reset it and start from fresh to make it better configured, its sadly one of them that cant have openwrt installed :/
i have another tp-link that have openwrt but missing wireless on 5Ghz, if i give op with it, i would need to search for a better router then
but it seems my pear bundled adsl now works stable :)
