SUMMARY
KDE Connect fails on different bands; other apps that works over WIFI on local network works fine

STEPS TO REPRODUCE

1. I use a dual-band Wi-Fi network where both the 2.4GHz and 5GHz bands share the same SSID (name). Both my Windows PC and Android device connect to this network.  Client isolation disabled in WIFI.
2. When I move away, my Android phone automatically switches to the 2.4GHz band for connectivity, while my PC stays connected to the faster 5GHz band.

OBSERVED RESULT
1. KDE Connect, fails to connect properly in this situation. Android and pc can't find each other even though both devices are on the same Wi-Fi network. Refreshing both don't work.
2. Interestingly, other apps such as Local Send and Snapdrop, which operate similarly to KDE Connect, continue to function correctly despite the band difference.
3. All windows firewall permission are given to KDE.
4. I also tried with making fixed IPs for my PC and android in my router DHCP settings. This bug still happens. Local Send and Snapdrop works fine on both situations.

EXPECTED RESULT
It should stay connected.

SOFTWARE/OS VERSIONS

Windows: 11 Pro Version 10.0.22631 Build 22631; 
KDE vesrion: 24.02.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2

Android: 14
KDE vesrion: 1.32.2 - Play Store



ADDITIONAL INFORMATION
KDE should copy how Local Send and Snapdrop.net works. Both open source, both more reliable than KDE Connect, but pales in comparison feature wise.
