Internet Painfully Slow When A Computer is Powered ON on Network

post #1 of 8
Thread Starter 
Hey guys,

so I've been having problems recently, where if my server is powered on, then my internet on my desktop will randomly tank at times, and then as soon as I turn it off it speeds back up. This is more than just "its a bit slower because more than one computer is on the network". It seriously tanks from being extremely fast to not usable. I've checked to make sure the server and my desktop aren't downloading anything and at this point I have no idea what the hell is going on.

I thought about an IP conflict? So I gave both computers a DHCP reservation (although I really don't know what I'm doing LOL)

Who is your ISP provider? You really can't run a server at home internet speeds, it swallows the bandwidth. you really need a dedicated commercial internet connection for your server to run properly if it needs to be connected to the internet. What are you using the server for?

Does your GPU (not CPU) show 100% usage? If yes you have bitcoin malware that is using your GPU to mine for someone else.

If a computer is slow only connected to the internet it usually is some form of malware.

the server is a home server, it doesn't send much at all through WAN, only LAN, and even then its slow when I'm not streaming anything. CPU and GPU are almost idle.

Was browsing google, found that a dying NIC could be the issue? Anyone think this is the problem? Im somewhat skeptical due to the fact that at times its fast, but then it will slow down until i shut off the computer

So I installed wireshark, and started to stream some stuff from my home server, and filtered the packets to just the IP of my server. The internet is working fine right now, and I did get a *few* bad packets, but I'm guessing that isn't something to worry too much about? 99% of them were fine

I guess I'm asking how the hell do I use this to diagnose the NIC LOL (again, I'm usually well versed with computers but servers and networking I'm somewhat of a noob at compared to you guys)

Could be a virus sending/downloading stuff. It doesn't happen too often, but it's possible.
