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…
