Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Do your phones not have a passthrough ethernet port? Since your plan has you wiring them. At-least then you could wire your desktops and have a backup plan incase your wireless goes down for your laptop users
what I would do is right click on the wireless network listed and go to properties. There check the security to make sure that it matches the security type that you set up on the router.
