I use a firewall, so none of these apply to me.

My firewall doesn't have wireless, I have a separate system of access points to provide wifi coverage across my house. Little White/beige squares dotted throughout to propagate the wireless in a coordinated effort to allow clients to connect, backhauled through a PoE switch to the firewall.

Any box my ISP gives me gets put into bridged mode and stuffed in a closet with the rest of my hardware. I never see it.

I don't like having network equipment out in the open, on shelves or whatever. All my aps are ceiling mounted and well out of the way, so they pose no more inconvenience than a smoke detector.

I have long since abandoned the consumer router industry. Most of it is borderline ewaste as far as I'm concerned. I don't trust my ISP to provide a good combination modem/router to use so all of their stuff is restricted to bridged mode, so it acts as a modem only. I won't fault anyone for not doing what I am, it's usually not cheap, but bluntly, I haven't had any significant problems with any of it since switching to this type of network, and I can upgrade any part at any time without throwing the whole thing away like you would have to for a consumer all-in-one wifi router. This path isn't for the feint of heart. It's much more difficult to manage when you need to, but when you get everything configured correctly, you basically can forget that it exists. The only down time I've had has been either power or ISP related. Obviously if the power is out, wifi doesn't work. If the ISP is having trouble getting your connection out to the internet, then all the equipment on my end isn't going to provide internet access, even if it's working flawlessly.

I've taken great pains to ensure that I don't need to look at, modify, or even think about my network or wifi very often or at all. It just works. It blends into the scenery and I don't even see it most of the time.
