That means there is no cure for this one. The router does have parental controls but a hard reset and it's game over.
As to the DD-WRT path, compile questions are put to DD-WRT forums.
Hey to you all!
I want to limit my youngest brother's internet access (he's addicted).
If I change password for router and set rules/mac filtering/wifi password etc., he can still hard reset router (by long-pressing reset button on it) and login/password will change to default admin/admin, giving him full access.
I don't want to use physical restrictions (keys, locks, boxes etc.).
I thought I'd try installing DD-WRT or similar CFW, but what I need is to set default login/password and wifi password in CFW BEFORE flashing this new CFW.
I think this will successfully prevent him access because even if he tries to hard reset, he won't know changed values (LAN access is not possible in my house, router is on the attic and you need to drill many walls to do so, other things like using adapters in electrical sockets is way too expensive).
This combined with passwords for my family's other devices will do the job, I suppose.
Is it possible? Can I compile myself this new firmware? Can I do this on Windows? I guess I'm decent with PC's, but I've never compiled things from sources on Linux, let alone making changes in them.
I really, really appreciate your help!
My router is TP-LINK WR740N V4
