GPON XX530v V1 - Download speed limited to less than 50MB
Hello everyone.
Model: GPON XX530v V1
https://www.tp-link.com/br/support/download/xx530v/
I bought a XX530v V1 GPON router to replace my ISP's router.
I configured all the GPON parameters and PPPoE authentication, and I successfully got IPv4, IPv6, and internet.
The problem occurs when the download speed is limited to less than 50Mb.
My plan currently has 500Mb download and 250Mb upload, and I have no problems with the upload exceeding the contracted speed.
I tried to install an ONU XZ000 G3 on the fiber and use the XX530v to dial PPPoE and route internet, but the problem persists.
Using the ONU and dialing PPPoE directly in Windows 11, the download and upload speeds are perfect.
I performed all my tests using a network cable and wifi, and got the same results.
I tried resetting the factory settings and reinstalling the firmware, but nothing worked.
Using the XX530v (via WAN port) connected to the ISP modem as a DHCP client, everything works fine.
Apparently the problem is related to the use of PPPoE and/or VLAN_ID.
