Re: Wired vs wireless
I have both. I wired myself back during the early days of cable modem, so it's a touch old with normal CAT5, but you'd be surprised how well it still carries things even now. And before that I had linked a few computer to a Linux-powered dialup box over 10-Base2 (yup,BNC cables run along the floor, at the time it was easier plus one of the devices could ONLY use coax, as it was a parallel-port adapter).
I have a wireless setup for those devices that must use it (laptops, phones, tablets, etc.), but to be on the safe side, my password's at the length limit and uses as broad a character base as I could use. I usually have to use WPS-PBC to add a device (WPS-PIN is turned off) because I can't remember it, it's so long.
