You're probably right. The setup they have now is an old netgear nighthawk with an AP to cover the second story. It works fine if it works, but it needs to be restarted when the prepaid internet shuts off and comes back. My dad rewired the AP and then wondered why it didn't work anymore.
There's the option of cameras where they can't make up their mind. If cameras I'd like an integrated system for everything, which is why I was looking for a modular approach. But if I use a Dream Router that's not even the case anymore, either.
I guess I have to tell them - once again - that we have to sit down and make up their minds about what they want. Then I can make up mine about what debugging options I want.
