I have a $250 TESmart HDMI/keyboard/mouse switch, after 6 months I have to power cycle it each time when I woke up the computer. Unreliable.
Also bought Synergy that works fine but I need keep the software running(a wifi switch will lose the connection, so it's not the same as the hardware kvm switch).
I now use usb-switch for keyboard/mouse only, and use my monitor's own button to switch displays, so far it is not convenient but "works".
If you bought the switch from them, their support is pretty good. I would recommend reaching out to them. Otherwise I guess reach out to who you bought it from.
