Bandwidth Issues

Anytime I download a file it uses up all my bandwidth. Can barely load a website.

This is my router: https://www.amazon.com/gp/product/B0787TRNMH/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I've done this, but then shortly after restarting it went back to the same issue.

Click Start and type "cmd."

- Right click on Command Prompt and run as administrator.
- Copy and paste the following line one at a time, pressing enter each time. You must press Enter after each command and wait.

netsh winsock reset
netsh int ip reset
ipconfig / release
ipconfig / renew
ipconfig / flushdns

Windows 11.

Thank you in advance!
