These false positives can trigger Windows to suddenly start reporting DNS server not responding errors.

To verify whether this is the cause for your device, temporarily disable the antivirus program. Next, re-run the Windows Network Diagnostics.

  1. Will static IP increase speed?

Ans: Some benefits of static IP address: 

  • Running servers

A big advantage of utilizing a static IP address is that it can host servers, which other computers can access using their internet connection. Because static IP addresses do not change, they can be located from just about any area in the world. Different devices and operating systems can also gain remote access to networks using the IP address.

  • Stability

These types of IP addresses also offer more stability, as they do not change like dynamic IP addresses. Dynamic IPs change often, sometimes every couple of hours, which can mean losses in connection while using the internet. You may find yourself having to reconnect while working on tasks and facing difficulties when reconnecting.

  • Faster download/upload speeds

Depending on your network, the speed of a static IP can be drastically faster than a device with a dynamic IP. DSL connections may not produce noticeable differences in speed, but broadband users with high-speed connections may notice an increase in speed that is over 1 megabit. If you tend to download or upload a lot of files, documents, and data, you may want to compare static and dynamic speeds.
