Over the years, I've accumulated several wireless routers as technology has improved and the units have become (relatively) cheaper. I've tried selling some of them, though usually all I can get is about $10-20 each. And rather than recycling them, I thought whether I could use them as switches by turning off DHCP and wireless. Does this really make them into switches? I'm probably missing some other functionality that isn't apparent to a non-expert in networking technology.
