Computer Disconnects From Servers While Gaming

[wagnerian1992]

So, this is my first time asking for help online because I can normally solve issues by myself. I'll give the system details at the end

To start out, a few months ago I clean installed Windows 7 Ultimate 64bit onto a brand new SSD, (Crucial MX500 1tb). Since then I have updated all the drivers completely but have had a continuing problem for several months. Whenever I connect online for games (Starcraft 2, Dreadnought, or even direct IP connections to friends) I can always manage to play the game for about 10-20 minutes before i get disconnected.

At first i thought it was an issue with the ISP, however I checked another computer and played games on it without any issue for hours. Both were connected by Ethernet. I have since tried several usb wireless, PCIe Nic cards, and wireless cards to connect but all have the same issue.

I have done IP pings and noticed that there is no issue until I play games, where I see a few packet losses. I ran the Realtek diagnostic tool for networks and kept getting an IRQ failure (conlfict with another device), but when I check Device manager I do not see any conflicts and when I check IRQs my Realtek GbE controller is on its own IRQ (-2). I cannot change any IRQs in my BIOS, though I don't think I would.

I have tried for months and have done many different things over and over again but have still seen this problem. Chances are I have tried almost all of the common solutions but I need ideas. Feel free to ask any and all questions and I will tell you whatever I can. God knows its probably something simple...


WINDOWS 7 Ultimate 64bit
Gigabyte ga78lmt-usb3 mother board v6
AMD FX-8310 3400 MHZ
GTX 750 ti
20 Gb DDr3 1333 RAM
CRUCIAL MX500 1Tb SSD


EDIT: Just looked at my IRQs in System information and it says that the Realtek GbE controller is IRQ 4294967294 but under my device manager it says the IRQ is -2. I do not know if that is an issue or not.

Negative IRQ means it's using Message Signaled Interrupts (MSI). A lot of (all) devices do on modern systems and IRQ conflicts is a dying issue. All PCI-e devices no longer use line-based irq.

https://en.wikipedia.org/wiki/Message_Signaled_Interrupts

Let's try this for starters: go to the NIC Properties and go to the Advanced Tab. Once there disable "Energy Efficient Ethernet", also in device manager untick 'Allow this computer to turn off this device to save power' in Power management tab of athe NIC.

Unfortunately I have tried those settings as well. I'll double check to make sure that they still are that way. Do you have any other suggestions?
I've often heard that IRQs are not an issue really anymore, but I feel like exhausted most of my options and this is just the most recent possibility (no matter how unlikely) that I have stumbled on.
Perhaps the other Realtek settings might need to be adjusted and unfortunately i don't know how those settings (Checksum offload, Interrupt moderation, etc) change the connection so I haven't messed with them much.

I appreciate the help.
