Wifi cuts for few minutes

At first, when I started using the Wi-Fi, it performed very well. However, around mid-year, it started losing connection for a few minutes before coming back. Whenever I call for support, the agent only performs basic troubleshooting like restarting the Wi-F which, frankly, even my 5-year-old could do.

For someone who works from home occasionally and relies on streaming, this is unacceptable, especially considering the amount I pay every month.
