Model: XX530v  
Hardware Version: V1
Firmware Version: 0.7.0 3.0.0 V6096 Build 250606 Rel 25672n

I was enjoying TP-Link XX530V XPON as the main OLT (a Direct Patch Cord from Airtel was inserted into the XX530V Airtel Nokia Router, which was shut down). Inernet over Wi-Fi and LAN was working fine till 3 days back, but all of a sudden Airtel did some changes in their FAT due to which my TP Link XX530V got impacted as when I removed the Airtel Patch Cord from the TP Link router I was able to communicate using LAN cable and the LAN ports were working but without internet and when I inserted the Airtel patch cord again Internet over Wi-Fi started to work whereas all LAN ports stopped working. I am wondering what caused this issue and how to resolve it.

  @AlokJain This issue cannot be fixed as this was caused due to some new LAN port allocations, making any TP-Link ONT with LAN ports unusuable over wired.
Only the XX530v v2 and XZ000-G3 with a 22 firmware can work. Unless we have the OLT config (which is next to impossible), this cannot be fixed.
Only option I see is, if somehow TP-Link decides to use 99% of the version 2 features of XX530v into the version 1 and release a firmware. Till then, you are good without the LAN Ports.
@Joseph-TP @Kevin_Z is there any XZ000-G3 v2 2022 firmware? This is extremely important right now for the internet to work, as any 2023 firmware makes the LAN port go offline when PON cable is plugged in.

Hello @AlokJain @IfranAli 

 

I apologize that I'm confused about the weird behavior in AlokJain's network.

 

Are you saying that wireless devices can access the internet when the Airtel Patch Cord is inserted into the GPON port on the XX530v, while none of the LAN ports receive valid IP addresses?

 

If you unplug the Airtel Patch Cord from the GPON port on the XX530v, are the LAN ports active?

 

I'm even more confused by this sentence 'This issue cannot be fixed as this was caused due to some new LAN port allocations, making any TP-Link ONT with LAN ports unusuable over wired'. Could you please explain and provide more details? @IfranAli

  @Kevin_Z When we use the v2 version of XX530v, all the LAN ports work normally. As soon as we use the v1 with every parameter similar to the v2, the LAN ports just doesn't work anymore, as if they are dead. It was not the case for a long time, but after some OLT changes on ISP side (ALCL), seems like most of the TP-Link ONTs (XX230v, XC220-G3/G3v, XZ000-G3 and XX530v v1) have this LAN port shutdown issue. Strange thing is that, VSOL-based ONUs and ONTs work perfectly fine, and another strange thing is, the newly provided ISP ONT is from Nokia, and whoever has the GPON SN of Nokia registered on OLT side, their setup has this issue. If you have the Zyxel variant, suddenly the issue is gone....? I don't understand the issue at all.
And yes, as soon as you take out the GPON Port, LAN ports magically work again (lol).
Wireless works regardless, only the LAN ports have this issue
