Killer E3100G 2.5 Gigabit NIC keeps disconnecting








Go To Windows Settings – Network & Internet – Scroll down and click “Network reset”
This will require you to restart your system.

Additional steps, if your NIC has similar features:

In Device Manager Network Adapters, right-click on Killer E3100G adapter and hit Properties.
On the “Advanced” tab, make sure the following settings are as below (I’m on a 1gbps line).

Advanced EEE – Enabled

ARP Offload – Enabled

EEE Max Support Speed – 1.0 Gbps Full Duplex

Energy-Efficient Ethernet – Disabled

Gigabit Lite – Disabled

Green Ethernet – Disabled

Interrupt Moderation – Disabled

Jumbo Frame – Disabled

NS Offload – Enabled

Power Saving Mode – Disabled

Receive Side Scaling – Enabled

Speed & Duplex – 1.0 Gbps Full Duplex

Leave anything else as default. Also, go into Power Management inside Adapter Properties and disable “Allow the computer to turn off this device” in case it still acts up.

Whenever you update/change the driver make sure you go through these settings again, as some might reset.

Completely fixed it on my X570 Taichi Razer. On my end, it was even worse as when it failed it completely disabled my router too (both a previous Archer C6 and now an AX20) and WiFi + NAS were inaccessible when the computer side went off.

Last resort if your System has been running fine, update your Motherboard Bios:

For Asrock x570 Taichi Razer Edition

**Be careful of Beta Bios, and if you have a motherboard with “Dual Bios” or “Flashback” capabilities then you have a safety net, but if not be careful during the flashing process. You don’t want to lose power during the system Bios flash, and again if your system has been running well, flashing your motherboard with a Beta Bios can cause system instability.

  1. Not sure where my original post went… but came to post that I found a work around:

    I bought a ELECTOP – [10Gbps] USB 3.1 GEN 2 Male to Type-C Female Adapter, Support Double Sided 10Gbps Charging & Data Transfer, USB A to USB C 3.1 Converter

    this has continuously worked for me as of today. important to make sure that it is (Double-Sided) by design if you plan to look around for other similar items.

    This is what I have:
    * Gigabyte Aero 15
    * OWC Thunderbolt 3 (14port) docking station

    Although my laptop model came with internal Killer NIC 2500, but for docking and undocking conveniences I went and got a USB-C version of this (Killer E3100 USB-C). I didn't realize others are having identical issue. My would drop connection any time with a predictable pattern, including playing online games if this was connected via USB-C port of my docking station. above described fixes that issue for me.

    (i'm not reseller, just want a perfect setup)

  2. I have a Gigabyte X370 Gaming K7 that kept disconnecting randomly on both Killer and Intel nics. Would sometimes take multiple reboots before it would connect again. Turned out to be a DNS misconfiguration. The Windows 'Metro UI' network settings kept failing to properly apply network settings and basically lied about the actual settings. After forcing the settings in Network Connections (Win7 interface) everything worked perfectly. I really don't understand MS logic on phasing out the Win7 style settings when they can't be bothered to update the Metro ones to not be fundamentally garbage.
