probably it's a very simple question, but I'm not a network expert.
At home I have a modem router with WIFI + LAN (D-LINK DSL-2680), in another room I plugged a switch (Netgear GS208) and then connected to it my XBOX and my Raspberry Pi (both with static IP). Well, with this configuration I can't even ping these two devices from my laptop using WiFI (I already checked and we are in the same IP class), but if I remove the switch everything works fine.
I checked on product page and they say I don't need a crossover cable, so my question is: what am I doing wrong?
I already tried to change ethernet ports, rebooting my router/switch and so on, but nothing works...
