A few months ago I hardwired the whole house with Cat6, weak Wifi signal in the basement where I moved my office. Brought a couple of SG105 for multiple devices in the same room. In the office, I have my laptop, printer, and PlayStation. Everything worked until a couple of days ago. Now my printer and PlayStation do not work. My laptop works in all the ports but the others don't work in any port now. I have moved them all around in the ports but only the laptop port lights up every time I move them.
