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 so many stupid steps before finally testing a direct connection to the ONT which finally made me call the ISP. I guess that is the difference between being an educated network engineer and a self taught enthusiast… 💔
The ISP is going to replace the ONT for free.


Sounds perfect to me. You thoroughly tested and eliminated every variable on your side before pointing fingers. Network techs hate it when someone starts blaming “the network” when it’s something stupid like a damaged cable behind the user’s desk.
Thanks! In that case, I am proud :D
