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

Welcome to our community.
Have you bought the xx530v via a retailer? Who is your ISP?
If you have the same question that XX530v is capped at 50 MB download, please try the suggestions of alb3530 as below:
In web UI, go to "Advanced" -> "GPON WAN", and edit the current WAN interface.
Go to the very bottom of the page and see if "Mac Clone" is active.
If it is, disable it, by choosing "Do not clone Mac Address".
I found many people online with that problem.
I did some tests, and my conclusion is if current WAN interface uses a MAC address that's NOT from Tp Link, download speeds will be limited to 50Mb/s.
What I did exactly:
Disabled Mac Clone, and connected to internet. Then I copied MAC address from WAN interface, available from Advanced -> Status page.
IF I clone this MAC address (by editing WAN interface), or if I increment the last character by 1, it connects normally, with full speed.
If I clone any other mac address (both from my original ONU, or a completely random value), downloads are limited to 50mb/s.
I don't know if it's a bug in firmware, or something that's been done on purpose to limit speed, but it's something that's happening exclusively on tp link devices.

@Joseph-TP Hi Joseph. This solution isn't good if isp requires cloning mac address. Many isps have this requirement. What can I do if I need to clone mac address?

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

@Joseph-TP Hello,
There is apparently another bug with IPv6 VoIP
It never tries to connect to IPv6 servers at all, and tried both with and without [::].
The Aginet app shows "via IPv6", but refuses to turn on. Only v4 works as of now.
Another bug is the USB ftp/http and https remote access is tied to my VoIP for some reason. my Static IP interface having priority of 0 cannot get the place, but VoIP interface with 4 gets it always, even though it has no internet access. Kindly get these fixed.
Router is good, firmware is not. Needs a lot more tweaking and fixing.
Also, kindly add ssh/telnet/uart access incase this device gets bricked, very annoying to work with such device without these features in 2025.
Thank You.

@Rabatonfr TP-Link must do something about it. It is a bug, TP-Link have to fix it.

@Rabatonfr Definitely a problem with this router. I have one of these, and Im facing this very same thing. Replacing the ONU with another device fixes the problem. The other device doesn't have a speed cap when mac address is cloned.
TP-Link must fix it ASAP!!!
