How to Flush Your Cache on Windows and Router

5/5 – (1 vote)

I work a lot with DNS settings for my websites and apps.

Today I added a few new DNS entries to set up a new server. I used DNS propagation checkers and confirmed that the DNS entries were already updated internationally. But unfortunately, I myself couldn’t access the website on my Windows machine behind my Wifi router. I could, however, access the website with my smartphone after switching off Wifi there.

This left only one conclusion: My browser, Windows OS, or router cached the stale DNS entries.

So the natural question arises:

Question: How to flush your browser cache, Windows cache, and router cache and reset the DNS entries so they’ll be loaded freshly from the name servers?

I’ll answer these three subproblems one by one in this short tutorial:

Step 1: Flush your browser DNS cache (Chrome, Edge, Firefox)
Step 2: Flush your Windows DNS cache
Step 3: Flush your router DNS cache

Let’s dive into each of them one by one!

Now your browser has no stale DNS entries — but in my case, this didn’t fix the problem. After all, your operating system may have cached it first!

Step 2: Reset Your Windows OS Cache

This one is simple (although a bit time-consuming): To reset your router DNS cache for sure, unplug your router and leave it unplugged for 30 seconds or more. This will reset its DNS cache for sure. Done!
