S21 Ultra WiFi Lag/Slow

Is anyone else having issues with WiFi on their S21 Galaxy device? Speeds are fine once the connection gets going, the problem is when I'm browsing web pages or doing anything that requires internet and it takes some time to load the site and images.

For instance if I go to Google.com, it'll just sit there loading for about 10 seconds before it finally goes to the page.

No other device on my network has this issue, and the issue isn't present on mobile data, it's only on wifi. I already rebooted my router, changed channels, and ensured it was connecting to the 5GHz band but still have issues.

Which browser?

Also, is there a Private DNS set?

Any browser. It's not just isolated to the browser though, it's system wide. And once the connection gets going, it'll work for a little before it does that pause again. I do use a pihole for DNS but I rebooted that and changed servers as well but still have the same issue.

Congrats on the use of a separate DNS server on your network.

The Private DNS I'm referring to, is a WiFi setting on the phone - it's a system-wide setting under More Connection Settings
