I admit it: I have too many Raspberry devices.
On the router I have only 4 Ethernet ports and should buy two switches. One for the lower floor (4 ports - router is also there) and one for the upper floor (6 ports).
What do I need to consider when buying a switch? What can you recommend me?
I ask you so that I do not buy crap.
Is it possible to run OpenWrt on a cheap switch? Or is this too advanced?
