Deco APP 2.7.4 and earlier version + iOS 14.5 and later version
Some customers may get a warning of DNS Hijacking after running Wi-Fi Diagnostics on the Deco APP -> Deco Lab -> Wi-Fi Assistant after they update the iPhone to iOS 14.5 version.
When determining whether there is DNS hijacking, Deco APP (2.7.4 and earlier version) will send a DNS query to a test server, such as google.com. After the APP receives the response, it will compare whether the returned URL address and the requested URL address are exactly the same. If they are different, the Wi-Fi Diagnostics result would warn the Risk of DNS hijacking.
After the iPhone is updated to iOS14.5 (and later version), Google might return a different URL address, which might be caused by some security updates added in iOS14.5 (and later version). Please don't worry, this DNS hijacking warning is not caused by any security issue of your network, your network is safe.
A new Deco APP version 2.9.6 has been released and please keep attention to the new version release on the Deco APP;
Please also feel free to let me know whether the issue has been fixed on the latest Deco APP.
