Alright, I had a minecraft server up originally on a server I made.
But when it went down I tried running it on my main desktop which used the Killer 2100 NIC.
But for some odd reason any computer running that piece of hardware couldn't create a homegroup or let that computer be pinged outside the network.

I uninstalled it, and removed it now using the onboard NIC but still the same issue remains.
No one can ping my server thru it's IP, not even myself I can only LocalHost it.

Anyone got any advice?
I added exceptions into the firewall for the programs, for inbound and outbound rules and still nothing.
Server IP is seriously try pinging it.

Computer repair I can handle anything to do with networking I'm completely lost at the moment.

I tried pinging it and it freaking works:p

I just pinged it fine too. Are you sure your ISP hasn't assigned that address to someone else. You can check your current address here.

Also, I'd double check that ICMP is allowed in your router. I know you said it was working, but can't hurt to double check.


I'm trying to run my minecraft server, I set everything up previously on a old comp I was using as a home server and it worked just fine, static IP, router ect, but on my desktop no matter which desktop it was it never had that capability I I believe it's cause of the killer 2100 net card I used I removed it and the software but still the problem eludes me, I'm tempted to do a reinstall of the OS to fix the problem.

Something had to have happened software wise during it's install to make a lingering problem now without the hardware or software just locating what the cause is, is driving me crazy.
The network card shouldn't have anything to do with it. Minecraft servers run on the default port of TCP 25565. You will need to port forward this in your router to the IP address of the minecraft server/PC.

There are plenty of examples on google.

As an alternative, you could probably enable UPnP on your router, assuming minecraft support UPnP.


I've done both, like I said It's not caused from the router, if it was the previous computer I had wouldn't have been able to run the server, I haven't tweaked the settings at all they are exactly the same as they were before, this computer is still hooked into that router also, so the port remains open.
Well, pinging your address shows that packets are reaching your router, so either your router isn't passing these packets on to the PC or the PC is blocking them. I know you said it worked before and nothing changed, but I would double check your router settings (port forwarding) and also the firewall on the PC the server is being hosted on. Make sure the firewall is allowing TCP on port 25565, assuming you didn't change the default port that minecraft listens on. If these are ok, then I'd try reinstalling minecraft.


it's all perfectly fine, hence why I'm saying it's a issue inside the OS, I noted this issue appears whenever I used the killer 2100 in it's build even after removing it the issue still remains, so I'm trying to locate what the killer 2100 actually disabled / tweaked and fix it so the packets get thru.
Their web site lists this for your killer NIC.

Application Blocking™ - Provides per-application control to block programs that access the network for increased performance and safety.

Maybe you should try using ccleaner and remove any remnants of the killer nic.
As I stated earlier, only the router and the/any firewall(s) should be in play if you uninstalled the killer NIC.

If the OS is reporting that port 25565 is not listening, then I can only assume minecraft isn't set up correctly. You should see the port listening even if the firewall is blocking it. In this case, the data packet would be dropped by the firewall instead of forwarding it on to the listening application.

I really don't think there is much more I can add to this. If you had a packet sniffer you can watch the flow of traffic on your LAN, but at this point it's probably useless since the port isn't even open and listening.
