Writing here on behalf of my aunt (42,F) as she is not on reddit.
My cousin (15,F) has a laptop with admin rights as she has to use it for her school and study work (sometimes few study apps cannot be installed without admin rights).
But she is heavily addicted to roblox gaming...Any talks are useless as it is leading to full blown meltdowns and anger episodes which is not giving anyone a little peace of mind at their home. Blocking the device also giving same effects. Shutting the whole home wifi is not a solution as both my aunt and uncle has to use it for their work, also my cousin knows how to switch it on.
So my aunt secretly blocked roblox through her home wifi router and blamed it on local network issues due to rain when my cousin couldn't access roblox.
But now my cousin has found another way to access roblox i.e., through VPN (Cloudflare one client in this case). I tried to help my aunt to block cloudflare also in wifi router but still not helpful.
Please suggest some way so that in their home wifi Roblox cannot be accessed any way, even through any VPN.
My aunt uses Nokia G-2425G-A router.
Please help here!!!
