Just a couple of days ago, my mouse and keyboard started to lag every once in a while. I noticed that when ever the modem lights aren't flashing, is when my keyboard and mouse lags. Its not the battery, and both of them are connected to a single USB drive. I went to check my Netgear router and there was my computer and a device under a list. It shows his IP address and MAC, but in the device name it says <unknown>. I only had my computer without any other device using Wifi. I changed my password and again the same device shows up, but randomly he doesn't come back. That didn't solve my mouse and keyboard delay issue, but I hope both issues gets fixed. Thank you
EDIT: The <unknown> user/device came back, but keeps disappearing.
Edit 2: I have their MAC address, what should I do?
