I'm rumnning Windows 11 and have have AVG and browser running on Lenovo ideapad 5i Pro 16" for two months. On Monday 13th June 2022 all DNS stopped working on three differnet browsers. Firefox 101.0.1, Chrome and Edge. I uninstalled AVG (free) and laptop worked properly again. After an hour I re-instaleed AVG again which after 10 minutes badly affected ALL WiFi devices on channels 2.4GHz and 5GHz on my BT hub router. Phones etc. would NOT reconnect until I uninstalled AVG+ AVG browser again and rebooted my router!
All stable now, but you need to investigate the DNS and WiFi issue.

Hello Sugavaneshwaran,
I tried to connect to another network/router with the same result - no DNS on any browser.
I did not disable each component in AVG, I just uninstalled it.
Sorry, but I do not have the time to reinstall AVG and run tests for you as it disrupts my whole home network.
I cannot put AVG back on my network as three people work from home and it causes too much disruption for them.
Please let me know once you think you have a fix for the problem.
Thank you.
