I'm not sure if I put this question in the right place. I have a fast internet from my ISP but am beginning to think I'm wasting my money. I have 800 Mbps, can I use the QOS Quality of Service setup in my router to slow the bandwidth (if that's the correct word) down so it would be like having the 100 Mbps package which costs a lot less. The speed test in the router is 147.47 Mbps download and 23.32 Mbps upload. In QOS I can define my bandwidth should I define upload as 47.47 Mbps save the lowered numbers and see if everything runs fine. I hope I made some sense, don't get angry, I'm old and will add another year tomorrow.
