DNS Cache problem recurring on Windows 11 Laptop

[JasonPang]

Recently my home upgraded our wifi routers and satellite, towards the end of the week I faced no issues. Until the same afternoon which it showed I was connected to wifi but refused to load. The next day, I used the built in network troubleshooter and it stated that there was a problem with the DNS Cache. I attempted to resolve this issue by checking for updates on windows, device manager, wifi driver was uninstalled and restarted, using Cmd prompt as admin to flushdns, manually routing DNS, restarting the laptop, forgetting the network and connecting again, disabling firewall and restarting the router and satellite itself. To which I have had no luck in solving the issue. There have been temporary fixes where most the time I get online for about 5-10 minutes before DNS cache issue comes back. All other devices connected to the network are working fine. My phone has no issue loading anything for long periods of time neither does other devices.

Im not sure if this issue is with the network or the laptop as Ive tried all solutions suggested to me on microsoft support about related issues and google. Flushdns, ipconfig release, reset, renew, netsh commands all doesnt work. Ive attempted to uninstall and reinstall wifi drivers, disabled wifi 6 and currently only running on Wifi 5, turned down roaming aggressiveness, ran diagnosis from advanced reset and it found that the wireless network had passed, full network resets, defaulted the power management and still have no luck. The wifi adapter used is "Realtek RTL8852BE Wifi6 802.11ax PCIe adapter" and is the most up to date according to device manager. There are no pending Windows update either. Thus the issue remains puzzling and frustrating. The issue only occurs on my home wifi and does not appear when connected to my hotspot or other wifi networks. Other devices in the same network face no issues.
