Hi! Thank you for reaching out. I suggest looking into routers that have content filtering or parental control features. These features allow you to block websites based on keywords, categories, or URLs.
One option you can consider is the Netgear Nighthawk AC2300 (R7000P). It has advanced parental controls that allow you to block specific websites or content using keywords. It also has a traffic meter that lets you monitor and control internet usage.
Another option is the ASUS RT-AC88U. It has a built-in Adaptive QoS (Quality of Service) that can prioritize internet traffic and limit bandwidth usage. It also has an AiProtection feature that blocks malicious websites and content based on categories.
Both routers are powerful and reliable, and should be able to meet your needs. However, do note that setting up these features may require some technical knowledge. Be sure to read the user manual carefully and seek help if needed.
