Nothing is wrong with them, it's just not necessary to have that many ports for an AP. A RB433G would cost less. RB493G would work for now if you really needed it gigabit though.You already have RB433 and RB493G, what's wrong with them?
Something like this:
how are you supposed to power a usb stick?Any device plugged in 411uahr USB port is not powered via USB port - external power adapter is required.
Normis,I think "those times" are when this switch costs 2x less (or even less that) of RB750G
