W9980B - No Internet connection via Lan, Wifi works

Hi everyone,

i just bought a W9980B and upgraded the firmware to the newest Version (Hardware V 1.0).
In Germany we have Annex B/J.
I get a perfect internet conncection via ADSL2+, where VLAN must be activated and set to channel 7.
However, i can only access the internet via Wifi (5G and 2.4G).

Via Lan i can only establish a connection to the router. Weirdly i CAN ping and dig websites. Also the routing seems to work there.
No matter whether i use DHCP or type everything in by hand it is not possible to open a browser and surf.

I have tried 3 different systems (Mac, Linux and Windows).
I tried with and without VLAN, however i cannot choose a WAN connection to group e.g. LAN and WIFI and WAN together.

Of course i have tried all four LAN ports.

I read through the manual but i found no hinge on "connection WAN and LAN". Anyway whats really weird is that ping works.

Has anyone experienced something like this?
What am i doing wrong?

Best regards
Douglas

I wanted to add some information:
I just changed to a FritzBox 7430. With the same VDSL cable i get 15.8MBit from my Box, whereas the TP Link only does 11.2 MBit.
Further if i stream something via WIFI (e.g. Netflix) and try to watch a Video on Youtube and surf (with another device) the TP Link gets very slow.
The FritzBox has no problem with it at all.

I do not understand why there is this big difference in performance. The quality of the TPlink seems to be VERY LOW!

Hi,

Did you try change the DNS on the router to like 8.8.8.8? What's the current firmware version of your router?

Hello,
i have the TD-W8970B and i have the same problem. ADSL2+ (Annex J) with VLAN 7 -> LAN Ports are not able to access Internet, but Router it self is accessable.
I tried serval things, but nothing seems to work. On my old ADSL AnnexB everything was fine.

It seems that TP-Link has there a general Problem with their Firmeware in several products.

So to solve the Problem it seems, that i have also to change to AVM (Fritzbox), because i need the LAN Ports.

I had the same issue but i got replacement of the device and now it works fine but i think the issue was from the modem's motherboard.

I contacted the German Support and they were nice and tried to help with "basic tryouts". From reseting, over changing DNS to google-servers and so on. But nothing helped.
Then they stopped replying. So i think TP-Link had no interests or ideas any more.

So my conclusion was like i wrote in the last message: I changed to AVM (FritzBox). Now it's working fine.
