    TL-PA8035P not compatible with IPv6

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    I have recently bought a TL-PA8035P kit and discovered that they seem to be not compatible with IPv6.

    I have made different tests and I was able to demonstrate that any equipment connected to any port of an adapter is not able to obtain an IPv6 address. All other equipments (wireless or wired) can obtain successfully an IPv6 address. My feeling is the incompatibility lies in the internal switch of the adapter because this IPv6 filtering happens even on the same adapter through the internal switch.

    Am I the only one to experience such a bug? Do you know how to enable IPv6?

    (Of course, I have updated the firmware to the latest available on tp-link website.)

    Many thanks for your help,

    Antoine

    Is the model number correct? I don't see a TL-PA8035P. But I know that TL-PA8030P support IPv6 but you need to contact tplink support to get the software to enable it.

    I can confirm the model number. It is sold (at least in France): http://www.tp-link.fr/products/detai...8035P-KIT.html

    I have already contacted by email the (french) support 2 weeks ago without any answer. What would you recommend to contact tplink support?

    The fastest way to get support in the UK seems to be to post a negative review on Amazon! Whilst I have never seen any support given by TP-Link on these support forums they seem to check and respond to Amazon reviews on a daily basis...Once you get in touch with them they are pretty helpful though, But any non routine questions / issues seem to require referring to HQ for an answer.

    Alternatively, the devices should pass any IP traffic - it probably just doesn't know how to deal with the v6 DHCP broadcast. If you set a SLAAC IP v6 address that might work - and SLAAC tends to be preferred for IPv6 networks.

    And do you really need IPv6 on your LAN? Many routers can gateway IPv4 on the LAN to IPv6 on the internet

    Thank you for the advice. I will try this route.

    I am using SLAAC but the Router Advertisement packets are barely passing through the adapter. After a while my system manage to acquire a valid IPv6 but unfortunately, it cannot contact any other hosts. This leads to a very poor user experience with plenty of timeouts before the OS switches to IPv4. For this reason, I have to completely disabled IPv6 for the hosts connected to the adapter.

    I will try to capture packets on both side to understand better what is filtered/blocked.

    I am heavily using IPv6 to access some private network/VM. I really need direct IPv6 access.

    I'm seeing exactly the same problem with the TL-WPA8730 Kit with both statically and dynamically assigned IPv6 Addresses.

    Considering I just bought this to replace 4 year old powerline wifi kit that handled IPv6 without a single problem this is shockingly poor and without a guarantee of an imminent fix this will have to be returned for a full refund as unit for purpose

    Just to follow up on this, I spoke to TP-Link support over live chat about this and to their credit they sent over an update which when applied to the WPA8730 does seem to have helped the problem - I only applied it yesterday evening so I'm still testing it but I definitely was seeing IPv6 working in initial testing.

    So for anyone else seeing the issue it might be worth trying tech support to see if they have anything to help.

    That does seem sucky that you have to ask, but then I guess these are sold as consumer level devices and relatively few home users need IPv6 these days!

    Sorry, but that's just plain nonsense. Internet service providers hook you up on IPv6, the main routers in people's houses do IPv6, Windows does IPv6. A simple home infrastructure gadget like a PLC adapter breaking it is flat out pathetic.

    I have to agree. I'm a home user and my ISP has been supporting IPv6 for more than 10 years and even the mass market ISPs in the UK like BT are FINALLY starting to roll out access.

    I'm not aware of a single ISP that defaults solely to "hooking you up" to IPv6. Sure many of them support it but for niche uses and you usually have to choose to enable it or even request it be enabled. And of those most are "dual stack" where you also still get an IPv4 address.

    For the vast majority of consumers IPv6 is simply not a requirement and is unlikely to become one any time soon. And much of the legacy router and wireless access point kit currently out there doesn't support IPv6 either. For instance Virgin Media - one of the largest UK ISPs - don't as yet support IPv6 at all.

    That being said I would expect kit on the market in 2017 should support IPv6 by default. But that this doesn't probably says a lot about just how few people actually care...

    In Germany, all VDSL is IPv6. Every single Windows 10 computer defaults to using IPv6 straight out of the box.

    That's really the end of the story, unless you work for a hardware vendor who can't get it right and tries to argue their way out of it instead of fixing their product.

    That's a particularly German situation then I think if you mean it's IPv6 only. How do they support the many devices that don't yet support IPv6? Or if you mean that IPv6 AND IPv4 are enabled by default then as above - most people wont care if they can't use IPv6.

    And sure WIndows 10 supports IPv6 - Windows has supported that out of the box since Vista. Doesn't mean you have to use it...

    It is IPv6 with IPv4 still supported as an extra. That's not the point though.

    Every single Windows PC uses IPv6 by default, and it's way beyond normal home users to dabble with that.

    The main point remains: In 2017, to have a brandnew home network infrastructure devices fail to support IPv6 is flat out pathetic. There simply isn't a viable excuse for this kind of miss.

    If it is the official standpoint of TP-Link that IPv6 need not be supported, then advertize your kit as IPv4 only. Let's see what that does to sales figures.
