Completely Stumped By Insanely Persistent Issue

[magamonkey]

Oh man, I feel really stupid after trying to fix this for so long. Generally, I have few problems finding fixes or causes for issues, I am trained in IT some myself, but I just have no idea what to do from this point.

The Problem: I have a desktop computer on which the connection intermittedly seems to become buggy. Things either don't load, or load very slowly. Importantly, it is not a full disconnect. While trying to figure out what was going on, I managed to do a speed test, which showed my download speed is the normal 50mb/s I am used to, while the upload speed is a couple kilobytes at best. Additionally, I often have a constant ping running to help my identify when the issue is happening. When the issue starts happening again, the ping test goes from being smooth successful pings to failing with a message of "Request Timed Out", but only about half the pings fail, and there is no regularity to which ones fail. While the issue is going on, I either completely lose connection or have one so slow that loading a simple webpage can take upwards of a solid two minutes. The problem is consistent across both my ethernet connection, and the wireless usb adapter I use. The only way so far to restore connection is repeated attempts to disable and re-enable the network driver a few times until a regular connection is restored. This issue has been going on for months, but has increased in frequency to the point that it can happen multiple times per hour.

What I have Tried that didn't work:
(this isn't an exhuastive list of every thing I tried, but it covers most of it)

• 
  Using a static IP
  Using a static DHCP Server
  Limiting running programs
  Updating Drivers
  Reinstalling drivers
  Using a different wire
  using exclusively the wireless connection
  using exclusively the wired connection
  Going to a friend's house to use their connection
  Screaming
  Using a network card
  Reinstalling Windows
  Using a fresh install of windows on a new drive
  Updating my bios
  Installing a new Motherboard (Same brand)
  Running without my GPU hooked up

My Build:

• 
  Intel - Core i7-6700K 4GHz Quad-Core Processor (CPU)
  Corsair - H60 54.0 CFM Liquid CPU Cooler (CPU Cooler)
  GIGABYTE - GA-Z270X-Ultra Gaming (Motherboard)
  G.Skill - Ripjaws V Series 16GB (2 x 8GB) DDR4-3200 Memory (RAM)
  Samsung - 840 Pro Series 128GB 2.5" Solid State Drive (OS Drive)
  Seagate - Barracuda 3TB 3.5" 7200RPM Internal Hard Drive (Data Drive)
  EVGA - GeForce GTX 970 4GB Superclocked ACX 2.0 Video Card (GPU)
  Antec - Twelve Hundred V3 ATX Full Tower (Case)
  Corsair - RMx 850W 80+ Gold Certified Fully-Modular ATX (Power Supply)
  Rosewill - RNX-N600UB USB 2.0 802.11a/b/g/n (Wi-Fi Adapter)

I desperately am looking for any help anyone can give me with this. I've been trying FOR MONTHS to resolve this. It's in the last few days that I replaced the motherboard and reinstalled windows on a fresh drive. At this point, I almost feel like it isn't even the same computer, yet this issue is equally as persistent as it was before! I can try to provide any info I missed, this is my first forum post.

I also have a image of what happens with the ping, but the forums seemed to state not to show ping info.

Is this a single PC problem? You are sure it has nothing to do with LAN, WAN, ISP?

I use the PC at home, and none of the other devices on the network, including my own laptop, have the issue. Additionally, I went to another friend's house with my desktop to test if the issue persisted and it did. None of the other five or so computers in his house have this issue. Also, the exact same issue happens on both my wireless adapter, and my LAN connection.

At this point all I can offer is, PCIe NIC card, not that expensive.

Unfortunately I tried that as well, Using the Network Card didn't prevent it from happening. I appreciate the suggestion, though.

check if your router has any bandwidth monitoring.

if not test with minimal variables. only have your pc on the internet with traffic monitor up. try on modem too. see if the issue persists. if it's good add stuff back slowly until the lag starts. if it doesn't work with windows you can try a live boot ubuntu.

common things that swamp your up are photo/video syncs to cloud or cloud backup

make sure you don't have any misconfigured qos.

it looks like you have killer nics. they have some of the worst ideas for nics. make sure to get drivers from the mobo site for them. if there is some suite for it go through all the settings and disable most of the bad things it's trying to do.

it advertises auto qos on the mobo page which sounds suspect.

Again, I went ahead and check at a friend's house to make sure the router was not related. Also the most I am every doing on my network is maybe watching a video and playing a multiplayer game. It's not exactly a big bandwidth draw. I will try to check in on the qos settings, though.

So in continuing to try to solve this issue, I updated my computer to Windows 10, still no change in the frequency of this issue. I did gather some more info, however. When the issue occurs the driver seems to reset itself, giving me a "General Failure" message in the ping log.

Not sure what is broken if you have tried multiple nics and still have issues.

You would have to swap out each piece to find the problem.

I'd try the live ubuntu if you haven't. could be a windows driver issue that's not in linux or some change you made and didn't realize it's impact.

make sure to use drivers from the manufacturer site and not just the find me drivers in windows.
killer nics have all kinds of stupid features that you can disable.

have you ever used software to try and forcebindip, use client qos, create virtual networking adapters for vms, bonded/slaved any of your hardware/virtual interfaces, or any other networking config?

look through your ipconfig for anything unusual.

I haven't done any of those things. Even if I had, during the process of trying to resolve this issue, I have completely reinstalled Windows from a blank state with no backup files. Shouldn't any settings causing a problem be gone after something like that??
