Windows 10: Problem with DNS cache

I have 3 yr old PC with Windows 11. The wifi internet connection is fine but pages won’t load. I rebooted router, restarted computer , followed suggestions on the trouble finder. Checked network is DHCP Connected. I also tried using command prompt to flush etc as per online connections. I could briefly connect to some sites, but now no pages will open . All updates are automatic. I could not find anything else to try to fix this problem. This has been happening only the last few days. I would appreciate any help or suggestion. Thanks so much!

Windows 10 DNS caching problem

After some time of messing around with the two windows 10 machines I have, one a laptop, the other a surface pro 4, I've consistently hit the DNS resolution issues that many other people have reported.

Basically what happens is DNS resolution stops functioning for a period of time, however previously cached domains still resolve. A simple and effective solution to this is to just flush dns cache with ipconfig /flushdns command. More frustrating is that
it appears when DNS resolution fails, nxdomain is cached as well (which may actually be a significant part of the problem).

Microsoft network engineering should take a good look at how the resolver cache is handled, as it appears that some failure which results in DNS resolution failure will end up with a cached nxdomain (which should never happen). The fact that a simple dns
flush fixes the problem instantly strongly suggests that there is a bug in this part of the code which needs closer examination.

 

DNS server causing problem

Hi Andrea,

DNS is a server that translates websites' addresses so that browsers can connect to them. If the addresses become outdated or the server has issues, problems and DNS errors occur. For us to provide an accurate solution, we would need you to answer the following
questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to your device before this issue occurred?
• Are you experiencing the same issue regardless if you are trying to be connected to a wired or wireless connection?

For initial troubleshooting, we suggest deleting the DNS cache. This can refresh the DNS files and settings on your PC. Follow these steps to delete the DNS cache:

• Using Search type Command Prompt.
• Form the search results, right click on Command Prompt (Desktop app) and then choose Run as administrator.
• In the Command Prompt window, type ipconfig /flushdns and then hit the Enter key.
• Once done, restart your computer and then check if the same issue persists.

We are looking forward to your response.

 

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.
