TCP/IP or Transmission Control Protocol/Internet Protocol handles PC communication. If the tcp/ip.sys goes corrupt, then it will misbehave and often lead to BSoD errors. Thankfully in this guide, we have a lot of solutions that will help you to resolve the tcp/ip.sys latency issue in your PC.

What can cause DPC latency?

There are several common causes for DPC latency, with the following ones being the most common:

Outdated drivers – Outdated drivers can cause this and many other issues. To fix it, just update your drivers and the issue should be gone. DNS cache – DNS cache can sometimes cause problems with your network adapter, but you simply need to flush DNS to fix that. Power settings – Adjusting the power plan or network adapter settings can sometimes fix this problem. IPv6 – This is a fairly new protocol, and it can cause issues with certain network adapter drivers.

Now that we know the reasons behind this problem, let’s apply the right solutions.

How can I fix tcpip.sys latency?

1. Flush the DNS cache

One of the ways to fix the DCP latency issue caused by tcpip.sys is to flush the DNS cache. Running commands removes the IP addresses or other DNS records from the cache.

2. Change the current power plan

Several users have reported that switching from the Balanced power plan to a high-performance or other power plan helped them resolve the tcpip.sys latency.

3. Update the network driver

Chances are the outdated network drivers are causing the tcpip.sys latency issue on your PC. Update the driver by following the above steps and check if this resolves the issue or not. SPONSORED Another simple and fast solution to keep your drivers updated and avoid future errors is to use an automated driver update tool.

4. Turn off the Energy Efficient Ethernet option

After doing that, check if tcpip.sys latency is gone. Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions.

5. Disable the IPv6

There are chances that the internet protocol that you have selected is problematic. In such a case, you can disable the protocol and check if this resolves the issue or not. If you are facing an audio latency issue on your Windows PC, you can check out our guide, which gives you a bunch of solutions to resolve the problem. You can also refer to our guide, which lists five effective solutions to resolve high ping, ping spikes, and latency issues on your Windows PC. Let us know in the comments below which one of the above solutions helped you resolve the tcpip.sys high DPC latency issue.
