Hello,
We finally had internet installed at our home after waiting for three months (with seven installation appointments, no less), and it works just fine with quick speeds for almost every device except for one: my laptop. While our other laptops and phones get 140Mbps, my laptop gets speeds that are basically unusable (around 0.1Mbps to 0.5Mbps if I’m lucky).
The laptop in question is a 2017 Macbook Pro running macOS 11.0.1. The modem is a KPN Box 12. Are there some settings on the modem that I can change to improve the situation?
