Archer VR1210V and Sky WiFi Internet Provider - working only with IPV6 but not with IPV4
2021-07-31 09:55:02
Model: Archer VR2100v  
Hardware Version: V1
Firmware Version: Archer_VR1210vv1_2.0.0_0.9_v6041.0_Build_210701_Rel.27192n

Hello,

 

I'm trying to replace the Modem/Router provided by Sky WiFi (a relatively new Internet Provider in Italy) with a TP-Link Archer VR1210v with a FTTC connection, but I can only make it work with IPV6 addresses and not IPV4.

Essentially I managed to connect the DSL and to get a public IPV6 address which allows me to connect to Internet but only to a limited number of sites (e.g. Google and Youtube work, but Speedtest.net does not).

If I enable IPV4 in the Internet configuration the modem doesn't connect to the DSL. If I disable IPV4 and leave only IPV6 enabled, and I manually provide the IPV6 DNS primary and secondary address then I can get through and connect to Internet, but only partially as I'm limited to the IPV6 stack.

 

Before I bought this modem/router I checked with the requirements provided by Sky WiFi (below) and to my understanding the Archer VR1210v covers all of them

  • IPoE IPv4/IPv6
  • NAT: MAP-T Mapping of Address and Port, Translation mode (RFC7599)
  • Encapsulation: IEEE 802.1Q VLAN
  • VLAN: 101
  • VDSL2 standard (ITU-T G.993.2)
  • Profili 8b, 12a, 17a and 35b (ITU-T G.993.2)
  • SRA (ITU-T G.993.2)
  • Retransmission (ITU-T G.998.4)
  • Vectoring (ITU-T G.993.5)

 

I feel I just miss the last mile to be able to solve the issue, and I'm looking for suggestions. 
Thanks in advance for helping out

 

Andrea

@Magilla 

Hi, have you tried IPv4 only configuration?

Did you get any PPPoE username and password from SKY?

Could you please send me two pictures of the advanced>status>internet when you used IPv6 only and IPv6& IPv4?

 

Thank you very much.

@TP-Link 

 

Hi, IPv4 only configuration doesn't work as Sky WiFi only give DNS via IPV6. If I check IPV4 the modem doesn't connect to the DSL at all, while it does it if I only use IPV6.

 

the provider doesn't use PPOE, but IPOE, and therefore there are no credentials to be provided.
