EDIT: Got an email from my ISP saying “the fiber owner has resolved your issue, we are closing the ticket.” I immediately called my ISP out of curiosity, since they earlier had told me that they need to change my ONT for me to get my full speed. Well, it turns out, the fiber owner (don’t know the English word for them) can manage speed per port on the ONT. Sic. So for some reason, they had limited the speed to 100 Mbps.
I purchased a 1 Gbps down/up connection and noticed that I was consistently getting 95 Mbit/s down/up, regardless of hardware configuration (router, no router, switch, no switch, connecting directly to the ONT, cat 6/6a cables, etc) and regardless of software configuration (VPN on/off, firewall on/off, OS Linux/Android, driver updates, etc).
When nothing seemed to help on my end, I finally called my ISP. They could confirm that my ONT is a decade old and that they can see that each port only allows for 100 Mbit/s down/up.
I went through these steps before finally testing a direct connection to the ONT which finally made me call the ISP.
The ISP is going to replace the ONT for free.


Thanks for sharing! I was also surprised and even tried to “provoke” an explanation as to why it wasn’t changed a long time ago, or at the very least, why they allowed me to electronically sign a contract that they would not be able to live up to…
And your story reminded me, that I really should try to remember to tell the technician that they are sending out sometime next week to check my cables! I’d hate for them to leave me a gigabit ONT with who know what ancient category Ethernet cables in my walls…
