Fix ERROR_NDIS_PAUSED (0x8034002A) – network offload paused

Quick answer: Open Device Manager, find your network adapter, right-click it, and select Disable device, then Enable device. If that doesn't work, run netsh int ip reset from an admin command prompt.

What's actually happening here?

The error code 0x8034002A maps to NDIS_STATUS_PAUSED. What this means is the Network Driver Interface Specification (NDIS) layer inside Windows has told your network adapter to pause a specific offload operation — usually TCP checksum offloading, large send offload (LSO), or receive side scaling (RSS). The adapter is stuck in a paused state and can't resume that operation on its own.

I've seen this most often after a laptop wakes from sleep or hibernate, or when a dock is disconnected while the machine is still on. The NIC driver loses its state and NDIS won't let it restart the offload until the adapter itself is reset. The real fix isn't to disable offloading entirely (though that works too) — it's to force the adapter to go through a full stop/start cycle.

Why step 3 works

The numbered steps below walk you through the most reliable fix first, then the nuclear options. Step 3 — disabling the adapter — forces NDIS to tear down the entire miniport driver instance. When you re-enable it, the driver re-initializes from scratch, and the offload state machine starts clean. That's why it works when nothing else does.

Fix steps

1. Open Device Manager. Press Win + X and select Device Manager.
2. Find your network adapter. Expand Network adapters. Look for your physical NIC — something like Realtek PCIe GbE Family Controller, Intel(R) Ethernet Connection I219-V, or a USB Ethernet adapter. Don't touch the virtual adapters (Hyper-V, VPN clients).
3. Disable and re-enable the adapter.
   • Right-click the adapter, select Disable device. Wait 10 seconds.
   • Right-click again, select Enable device.
   • Your network will drop momentarily, then reconnect. The error should be gone.
4. Check the error now. Try whatever operation was failing — copying files over SMB, a speed test, or a large upload. If it works, you're done.

Alternative fixes if the main one fails

If disabling and re-enabling didn't help, the problem might be deeper — the offload state is corrupt at the system level. Try these in order:

Reset TCP/IP stack

Open an admin command prompt (right-click Start, Command Prompt (Admin), or PowerShell as Admin). Run these commands one at a time:

netsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Reboot after. What this does: netsh int ip reset resets TCP/IP parameters to defaults, including offload-related registry keys under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters. The winsock reset clears any stuck socket state. This fixes cases where the NDIS pause is tied to a cached TCP connection.

Disable hardware offloads via registry (nuclear option)

If the error keeps coming back — especially on a Realtek or Qualcomm adapter — the offload features themselves might be buggy with your driver version. You can disable them without uninstalling the driver.

1. Open Device Manager, right-click your NIC, select Properties.
2. Go to the Advanced tab.
3. Look for entries like Large Send Offload (LSO), TCP Checksum Offload, UDP Checksum Offload, Interrupt Moderation, or ARP Offload.
4. Set each of these to Disabled.
5. Click OK, then reboot.

This forces every packet to be processed by the CPU. You'll lose a tiny bit of throughput, but the NDIS pause error won't appear. I've had to do this on older Realtek chips (RTL8111 series) where the driver has a known bug with LSO under Windows 10 22H2.

Update or roll back the driver

Sometimes the problem is that your driver is too new for your chipset, or too old for the current Windows build. Go to your NIC manufacturer's website and download the latest driver directly (don't trust Windows Update for this).

If you just updated and the error started, roll back: Device Manager → right-click NIC → Properties → Driver tab → Roll Back Driver. This has saved me twice on Intel I219-V adapters after a Windows cumulative update broke things.

Prevention tip

This error is almost always triggered by a power state transition. So the single most effective prevention is: disable the network adapter's ability to be turned off to save power.

Go to Device Manager, right-click your NIC, Properties → Power Management tab. Uncheck Allow the computer to turn off this device to save power. That's it. The adapter will stay alive during sleep, and you won't hit the paused state.

If you're on a laptop, also go to Control Panel → Power Options → change plan settings → Change advanced power settings → expand Wireless Adapter Settings → set Power Saving Mode to Maximum Performance. This prevents the OS from aggressively throttling the NIC during light usage.
