Good day:

I have a MSI z87M Gaming with built-in network adapter Killer e2205, i have random disconnects (red cross on network icon on taskbar) like the cable has been unplugged.

I disabled Killer e2205 and bought a new Gigabit NIC from TP-LINK, but problem persists.

There are 4 PCS connected to the router (mine included) and all 3 work fine 24/7, only mine disconnects.

My cable is CAT.6 and 25m, usually i can download files at 32Mbps (300MB) without any problems, even 50GB files, but when i play league of legends 1 of every 4 or 5 games randomly disconnects my ethernet for about 10-15 seconds and reconnects, works well for about 10 seconds and again disconnects, then reconnect and works fine for hours.

It happens sometime when browsing videos (not watching), when watching videos never disconnects.

So far, i know:

-It's not the router/modem fault because 3 PCs works perfectly all the time
-It's not the NIC because i replaced it and problem persists

Maybe is:

-Some malware or virus
-Cable is faulty

Thanks in advance and sorry for bad english.
