Hello@shu006 ,

Is the address you cloned the old ONU's address or the PC's MAC address?

I just ran test after enabling mac cloning. Download speed dropped below 50mbps. So it’s confirmed issues is with router.

  @Yash_Kanawjia ,

Thank you for your active participation in the discussion and extensive testing. This has been very valuable to us all.
For more analysis, I've forwarded your case to the TP-Link support engineers, who will contact you using your registered email address later. Please keep an eye on your email inbox for follow-up.

Hello @grad1e 

Could I know why the ISP insists on using Mac Clone? Why can't you directly use the TP-Link WAN MAC?
We would also like to know whether the ISP has given you a clear and detailed response. This is also very important to us.

 

Best Regards.

I am having the same issue. My ISP needs the MAC to be cloned in order to even connect. If I use the TP Link's MAC, it wont' connect. I even asked my ISP to release the MAC address. But they are not doing it. 

 

In this case, what can we do?


ISP: Keralavision, India

  @Yash_Kanawjia lets hope they fix the firmware, ASAP.

I haven't heard from them since Monday. I'll post any updates as soon as they get back to me.
 

 

Hehe, no. Eventhough we both have the same devices, the ISPs are different. And IDK hindi 🤣

Oh LOL, I was so surprised at that moment, but oh well

Also you're not the guy from the YouTube channel Geeky Twins, right? I mean, I was amazed when I read you had the VSOL 2802RH, HSGQ SFP XPON ONU on hand. He has the same ones and uploaded videos about it. Plus, you already have the XX530v like him, so three coincidences in a row left me stunned! 😂

  @grad1e That would be great! This would surely rule out any throttling done by the ISP and put all focus on the XX530v's faulty firmware. You may do the testing at your leisure, I don't think there's any reason to rush getting the results from the other ONT/ONUs as I believe the evidence we have collected up till now should be plenty for them to take it as a router-related issue, if they don't remain ignorant and actually listen.
Just talked to the engineer 15 mins ago, I told him verbally what we discovered and he said 'so throttling is when MAC Cloning is enabled. Okay, I'll check from my side' (translated from Hindi). Also forwarded him the Report made and screen recording of me doing PPPoE + MAC Cloning from Windows and getting full speeds in speed tests.
Will update you once he gets back to me. I hope they don't brush it off and call back to give updates on the issue.

  @Yash_Kanawjia I have the VSOL 2802RH, HSGQ SFP XPON ONU, Archer C64 and Archer C6. I can use that to verify that the firmware of XX530 is surely the cause. But i might need a few days to test it out since I am currently at a different place right now

Great bro. Let's hope they admit that it's the firmware that throttles the speed and not the isp

@alb3530 @grad1e @shu006 
I have complied a formal report that I'll be forwarding to TP-Link. I hope you all don't have any objections as I have mentioned you all as contributors and quoted your messages

  @grad1e Hey, that's some valuable information you gathered right there. Thanks!

 

I also ran some tests of my own to rule out that its my ISP that is throttling the speeds due to it detecting 3rd party device on network. What I found out makes it more evident that its something with the firmware.

What I did- 

  1. Put the XX530v in Bridge Mode and disabled the PPPoE interface on the router.
  2. Cloned the MAC address of the ISP provided ONT onto the Ethernet adapter of my computer. This is the same MAC that I'm cloning on the XX530v as well.
  3. Setup a PPPoE Dial Up profile on the computer and connected to it. Authentication was successful and I had internet.
  4. Ran the same 3 speed tests as the ones ran by the TP-Link Engineer so he when I tell him he at least he believes.
  5. In all the speed tests I got my full designated speeds of 100 Mbps Up/Down.


This hardens the fact that the firmware is faulty. 

Tomorrow I'll contact the engineer again and inform of all the findings we have gathered.
