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?
