XX530v is capped at 50Mb download in a 500Mb plan

I installed this device in my house, put fiber directly on it, it registered without issues.
But I noticed a odd issue:
Any download is always capped at 50Mb/s (my plan is 500Mb/s for both downloads and uploads), but UPLOADS happen at full speed (500Mb/s).
I tried some troubleshooting but nothing seems to work!
If I return to the old ONU I was using, it downloads at full 500Mb/s (ONU in bridge mode and XX530v connecting via PPPoE).
As soon as I return the fiber cable to XX530v, the problem happens again.
I suspect it might have to do with firmware (I've updated it to latest firmware), but the problem is I can't find the original firmware that came with it (Firmware Version:0.4.0 3.0.0 v6096.0 Build 240426 Rel.38762n).
ISP told me this router is compatilble, and they advised me to contact TP LINK, which I'm doing, because it might be a software fault on device's side.
Local TP Link support couldn't help me. They just say the same old stuff like "this router is targeted to ISP, so ISP has to help you... etc etc etc".
It seems this is a secret device only ISPs have access.
I mean, come ou guys! This router is sold in many places, and we currently can buy it from stores and install it ourselves.
TP LINK has to support this device because it's sold to end users!
My network already directed me to contact Tp Link, so I demand a solution!
And my ISP is very open, you only need the right GPON SERIAL to connect. Pratically any device can be used in their network as long as the GPON SN is right.
I even tried another ONU (different from the original) and no problem with it as well.
There was even a similar topic in this forums with the EXACT SAME PROBLEM.
GPON XX530v V1 - Download speed limited to less than 50MB
Can anyone escalate it to engineers?

@Yash_Kanawjia lets hope they fix the firmware, ASAP.
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! 😂
Hehe, no. Eventhough we both have the same devices, the ISPs are different. And IDK hindi 🤣

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

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

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

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 @shu006 ,
It looks like you changed to a new ISP, and your devices are now receiving full speed, right?
Which Mac were you using when connecting to your old ISP's network? Was it the TP-Link Mac or the Mac that cloned the old device?
Did both Mac addresses successfully connect to the network, or did only one work?
If only the Mac clone worked with the XX530v, have you contacted your ISP to find out why they required the Mac clone?
Have you directly tested the connection using the TP-Link Mac? What will be the specific manifestations?
Looking forward to your reply!

I changed my broadband from excitel to RailTel. They don't bind mac. Now I am getting full speed with xx530v.
Also there is no issue with using blue cable with green port. So its confirmed. Issue is with tplink firmware.

@Joseph-TP I cloned MAC address from ONU that Excitel provided.
I contacted excitel to change mac or remove Mac binding. But they refused by saying our device work best with our infrastructure. ( I know they are just making it up ).
I did these tests
Test 1 ---
Broadband - Excitel
Mac cloning- disabled
Result - pppoe does not connect
Test 2 ---
Broadband - Excitel
Mac cloning - Enable, Using excitel's onu mac
Result - pppoe connects but speed limited to 50mbps
Test 3 -----
Broadband - Excitel
Excitel onu on bridge mode
connected onu and xx530v via lan cable
mac cloning disabled
Result - EWAN pppoe does not connect
Test 4 ----
Broadband - Excitel
Excitel onu on bridge mode
connected onu and xx530v via lan cable
mac cloning enabled and used onu's mac
Result - EWAN pppoe connects but speed limited to 50mbps
Test 5 ----
Broadband - Excitel
Excitel onu on bridge mode
connected onu and AXE75(another tp link router) via lan cable
mac cloning enabled and used onu's mac
Result - pppoe connects and getting full speed (200mbps)
Test 6 ----
Broadband - RailTel (300mbps)
Mac cloning off
result - pppoe connects and getting full speed
Test 7 ---
Broadband - RailTel
Mac cloning on (added random mac )
result - pppoe connects but speed limited to 50mbps
Test 8 ---
Broadband - RailTel
Mac cloning on (added xx530v's mac )
result - pppoe connects but speed limited to 50mbps
Note - Railtel didn't gave me any I already had xx530v and they said Railtel does not bind mac so any device can be used.
