I hope someone can help me here.
I have a home network running Windows 10. There is one hardwired computer and printer and a Linksys WRT1900AC router. All the remaining devices are wifi connected. There are iPads, iPhones, Xbox, Fire TV, a Apple TV box and a wifi connected computer. The network runs quite smoothly. I am however, having some major issues with my son. Specifically for this forum I am referring to his ability to hack into the network.
As I mentioned before, I have a Linksys WRT1900AC router. It is currently setup to allow only MAC addresses that I approve. The router is setup to allow only the MAC addresses I approve, on the network. Each access to the router (2.4GHZ, 5GHz and Hardwire) are password protected. I even have parental controls setup. For some time now, every time I login to the router (from my phone or wired pc), I have noticed that the parental controls change. They are changed to give him more time on the computer. At first I thought it might be the router flaking out. It wasn't long before I found out that my son was indeed hacking into the router.
While researching the net I came across a number of helpful ideas to limit access. What I haven't found yet is how he is able to determine, within minutes, what my new router password is. It doesn't matter if I change it, he is still able to get into it. I wanted to turn off remote administration but my wife was against that. Maybe I haven't searched long enough but I have seen a number of hacks when the default password had not been changed. This however, is not the case with my router. I changed the password right from the beginning.
I'm guessing he is using some type of app to break in.
My goal is to not only keep him out but everyone else as well.
Any help would be appreciated.
